TCO has declared force majeure effective January 23, 2026 due to an unexpected mechanical failure at Emporia Compressor Station Unit 3 in Greensville County, Virginia. As of this third revision (last updated March 20, 2026), TCO states there is no anticipated commercial impact under current operating conditions, but the Emporia VA-34 interconnect (E13) may be restricted if pressures or nominations fluctuate. No restoration timeline has been provided and the force majeure remains active with no confirmed curtailments.
Force majeure remains active at TCO Emporia CS with no confirmed volume curtailments and no restoration date; monitor Transco Zone 4 and Dominion South basis for any tightening if E13 interconnect restrictions are triggered.
Reroute: Moderate: Texas Eastern (TETCO, monitored) and Equitrans serve overlapping Appalachian/Mid-Atlantic markets, providing partial reroute options if commercial restrictions materialize at the Emporia E13 interconnect.

Notice Text:
Columbia Gas Transmission, LLC (TCO) notifies customers that an unexpected mechanical failure at Emporia Compressor Station Unit 3 in Greensville County, Virginia has created a potential inability to serve that cannot be prevented or overcome by the due diligence of TCO. Therefore, pursuant to Section 15 of the General Terms and Conditions of TCO’s FERC Gas Tariff, TCO is declaring a Force Majeure effective for Gas Day Friday, January 23, 2026.
Based on current operating conditions, there is no anticipated commercial impact related to this unexpected event. However, if restrictions become necessary due to fluctuating operating conditions including operating pressures and nomination levels, the Emporia, VA-34 interconnect (E13) may be impacted. TCO will provide as much advanced notice as possible if commercial restrictions become necessary.
TCO will provide updates as additional information becomes available. Please continue to monitor critical notices and the Daily Capacity Posting for any adjustments related to this Force Majeure.
Reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 38 of TCO’s FERC Gas Tariff (“Tariff”). However, TCO will only issue RCCs if TCO is unable to schedule and deliver primary firm nominated capacity as a result of the Force Majeure for a period greater than ten consecutive days. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day average usage quantity less any scheduled and delivered quantities on the contract. By means of this notice, TCO is establishing which specific Gas Days will be included when determining a shipper’s 7-day average usage quantity pursuant to the provisions in the Tariff.
Please contact your Customer Services Representative with any questions.

Author: Author: Jonah Skiles
Notice Text
In an effort to communicate current operating conditions to customers, Columbia Gas Transmission, LLC (TCO) is issuing the following Operational Alert effective Saturday, August 29, 2026, and continuing until further notice.
Potential Critical Day for Storage Injections:
It may become necessary for TCO to limit storage injections to firm quantities only, which would constitute a Critical Day in storage. The potential for a Storage Critical Day is due primarily to forecasted mild weather, higher storage and line pack levels, and reduced market demand resulting in increased daily injections into customer’s storage accounts. Customers can assist TCO operations and reduce the potential need for a Critical Day by not exceeding their Maximum Daily Injection Quantities and keeping supplies and markets balanced.
Firm Storage Service (FSS) shippers are reminded that, per section 3(c) of the FSS Rate Schedule, the Maximum Monthly Injection Quantity (MMIQ) for August is 18% and September is 13% of the Storage Contract Quantity (SCQ), and the Maximum Daily Injection Quantity (MDIQ) is 1/25th of the MMIQ.
Pre OFO – Receipt Points in Market Areas 26, 30, 35, 41, 42:
TCO notifies all Shippers under all Transportation Rate Schedules within its FERC Gas Tariff, and Meter Operators in Market Areas 26, 30, 35, 41, and 42, that the issuance of an Operational Flow Order (OFO) may become necessary beginning as early as August 29, 2026, to preserve system integrity and protect the operating performance of TCO’s pipeline system.
Pursuant to Section 17.1(d) of the General Terms and Conditions of its Tariff, TCO is providing advanced warning of the operational variables that may in the future give rise to the issuance of an OFO. The operational variables that may require issuance of an OFO in the future are the following.
Due to forecasted mild weather and the anticipated lower market demand, TCO has experienced excess receipts during a time when storage and line pack levels are high. TCO has limited operational flexibility for positive imbalances and cannot allow actual receipts to exceed scheduled receipts.
In order to avoid the issuance of an OFO, receipt points must be balanced such that actual receipts into Market Areas 26, 30, 35, 41, and 42 are equal to or less than the scheduled receipt quantities in these Areas. Any excess receipts can threaten the operational integrity of TCO’s system and TCO’s ability to maintain its firm obligations. An OFO may also be avoided if Shippers and Meter Operators adjust nominations to align with flowing supplies during each nomination cycle.
In the event TCO is forced to issue an OFO, Shippers who do not comply will be subject to penalties in accordance with Section 19.3 of TCO’s Tariff.
Imbalances and AutoPAL:
As noted above, TCO has limited operational flexibility for positive imbalances, including positive AutoPAL balances. Physical flows must match scheduled quantities to prevent further action. As a reminder, the intent of the AutoPAL service is to utilize nominal quantities to resolve minor pool imbalances that result from small upstream or downstream reductions during the cycles of the Gas Day. These quantities are then paid back the next cycle of the Gas Day.
TCO will monitor AutoPAL activity and reserves the right to adjust the current AutoPAL limits, make AutoPAL unavailable, or declare an OFO to prevent abuse.
TCO encourages customers to monitor critical notices, including the Daily Capacity Posting, for updates. Please contact your Customer Services or Marketing Representative with any questions.

In an effort to communicate current operating conditions to customers, Columbia Gas Transmission, LLC (TCO) is anticipating it may be necessary to implement as early as issuing the following Operational Alert effective Saturday, September 5, 2026, and continuing until further notice.

OFO – Receipt Points in Market Areas 26, 30, 35, 41, 42, Effective September 5, 2026
SEV 3/5
Operational AlertUntil Further Notice
TCO has issued a formal OFO effective Gas Day September 5, 2026, requiring shippers with receipts in Market Areas 26, 30, 35, 41, and 42 to align physical receipts at or below scheduled quantities. The OFO is driven by mild weather, reduced market demand, and elevated storage and linepack levels causing excess Appalachian production to threaten system integrity. The order runs until further notice, with penalties up to three times the Columbia Gas Appalachia spot price for non-compliant shippers.
TCO receipt-side OFO across five Appalachian market areas caps physical injections and forces upstream producers to curtail flows into the basin, adding bearish pressure to Columbia Gas Appalachia basis, which was already at -1.265 vs Henry Hub on 2026-09-03 (five-day average -1.122); no volume cap is stated, but the open-ended duration and system-wide geographic scope across MAs 26, 30, 35, 41, and 42 keeps downward pressure on Dominion South and TETCO M2 as excess supply is trapped in the Appalachian basin.
Reroute: Limited: the OFO restricts the receipt side of TCO's Appalachian network; affected producers have few near-term alternatives as TETCO (monitored) and TCO are the two dominant Appalachian takeaway pipes, and any TCO receipt constraint that backs gas up in the basin similarly pressures available TETCO capacity at M2 points. Some modest diversion to Rover or REX Zone 3 is possible but unlikely to absorb material volumes given the broad market-area scope of the OFO.

Notice Text
Pursuant to the provisions of Section 17 of the General Terms and Conditions of its FERC Gas Tariff, Columbia Gas Transmission, LLC (TCO) is issuing an Operational Flow Order ("OFO") to Shippers under all transportation rate schedules with receipts in Market Areas 26, 30, 35, 41, and 42 to protect the operational integrity of TCO’s system and its ability to meet its firm service obligations.
As explained in Pre OFO (Notice ID 26205016), due to mild weather forecasts, anticipated lower market demand, higher storage and line pack levels, and the level of production received in Market Areas 26, 30, 35, 41, and 42, physical receipts must be equal to or less than scheduled receipts in order to maintain system integrity and provide reliable firm service. Consequently, TCO cannot allow excess receipts at any receipt point in these Market Areas.
Therefore, TCO is issuing the following Operational Flow Order (OFO):
1. The Time and Date of Issuance of this OFO is Friday, September 4, 2026, at 8:05 AM ET.
2. The OFO will become effective for Gas Day Saturday, September 5, 2026.
3. This OFO will continue in duration until TCO issues further notice of termination of this OFO.
4. The Shippers impacted by this OFO are those scheduling receipts of gas in Market Areas 26, 30, 35, 41, and 42 whose physical receipts are not less than or equal to their scheduled receipts during a Gas Day.
5. Pursuant to the OFO, the following actions must be taken:
During the period this OFO is in effect, impacted shippers must align scheduled quantities with physical quantities in Market Areas 26, 30, 35, 41, and 42, which may require communication with upstream operators. Shippers must remain in balance at the start of, and throughout, each Gas Day, beginning Saturday, September 5, 2026, and continuing until further notice. Receipt points must be balanced such that actual receipts into Market Areas 26, 30, 35, 41, and 42 must be less than or equal to the scheduled receipt quantities into these areas unless otherwise mutually agreed on a nondiscriminatory basis.
6. The justification for issuing the OFO is as set forth above.
7. Additional information: Shippers who do not comply will be subject to penalties in accordance with Section 19.3 of TCO’s FERC Gas Tariff. Shippers are encouraged to stay coordinated with upstream suppliers regarding changes in physical flow for the duration of the OFO.
If a penalty is assessed, the penalty will be based on all quantities in aggregate in violation of the OFO in excess of a tolerance of 5% of scheduled receipt quantities or 5,000 Dth whichever is higher. This tolerance will be in effect during the OFO unless revised through an update to this notice. Penalties will be based on the shipper’s prorated share of the total excess quantities above the tolerance at the receipt point for that day at the higher of: (i) a price per Dth equal to three times the midpoint of the range of prices reported for "Columbia Gas, Appalachia" as published in Platts Gas Daily price survey for the days on which the OFO is issued, or (ii) a price per Dth equal to 150 percent of the highest midpoint posting for either: Mich Con City-gate, Transco, Zone 6 Non-N.Y., or Texas Eastern, M-2 Receipts as published in Platts Gas Daily price survey for the days on which the OFO is issued. Penalties under Section 19.3 (ii) will only be assessed on days in which the daily spot price of gas exceeds three times the midpoint of the range of prices reported for "Columbia Gas, Appalachia."
Please contact your Customer Services Representative with any questions.

A bid must contain all of the applicable information required by the attached Bid Form at the end of this posting. Bidders must satisfy creditworthiness in accordance with Columbia’s Tariff. A potential shipper may submit multiple bids, each higher than its preceding bid, for all or any portion of the capacity or term of service made available by Columbia in this open season. Bidders may bid on Package 1, Package 2, or both packages. If a bidder submits multiple bids, Columbia will consider only the last, highest bid submitted by bidder for the purpose of awarding capacity offered in this open season. Bidder shall specify that they are bidding the Total Effective Rate (defined above) or a monthly reservation rate (or other firm or demand charge(s), if applicable, herein referred to collectively as “Reservation Charge”) it is bidding for the service. The rate for the monthly Reservation Charge shall be expressed as a monthly rate per dth and shall be expressed to the nearest thousandth of one dollar ($0.000). For bidders proposing a Reservation Charge or other form of revenue guarantee which exceeds the current applicable Recourse Rate during all or any portion of the term proposed by the bidder, the net present value (“NPV”) calculated for the bid may not exceed an NPV that is calculated assuming that the Recourse Rate shall be in effect during the full term proposed by the bidder, in place of the reservation rate(s) or other revenue guarantee(s) proposed by the bidder. Any bid, other than a contingent bid, not withdrawn before the close of the bidding period will be binding.
Assessing Bids- Columbia reserves the right to reject any bids that do not conform to the primary points or terms listed herein or any bids at a discounted rate. Columbia reserves the right to reject any bid that is incomplete or includes conditions or provisions that Columbia determines, in its reasonable discretion, to be unacceptable. The NPV for each package of any bids submitted in this open season will be determined in accordance with Section 4.4(b) of Columbia’s Tariff. Bids will be assessed based on the total NPV to Columbia as determined by adding the individual NPV for bids on Package 1 and Package 2 offered under this open season (“Total NPV”). If a shipper does not bid for both packages in this open season, the NPV for the package not bid on will be 0. Columbia reserves the right to reject any bid or request that contains modifications to the Bid Form or conflicts with Columbia’s Tariff. Columbia has the right to clarify bids.
Total NPV is calculated as (NPV of Package 1) + (NPV of Package 2). Individual package NPVs will be calculated as follows:
Package NPV = ? n [R*(1 / (1+i) ^ n)]
? n = Summation of months 1 through n
n = term in months of applicable package
R = Incremental monthly revenue for the applicable package (Package Bid Rate*Package Contract Quantity)
i = Monthly Discount Rate (the current FERC quarterly rate which can be found at https://www.ferc.gov/enforcement-legal/enforcement/interest-calculation-rates-and-methodology)

If two or more bidders submit acceptable bids of an equal NPV, and which are conforming to the terms of this notice, and there is insufficient capacity available to serve all such bidders, then Columbia shall determine the successful bidder based on the order in which the bids were received.

Columbia notes that the maximum applicable Recourse Rate for the capacity offered in this open season is the Total Effective Rate (maximum base tariff rate plus all applicable surcharges) for Rate Schedule FTS, as set forth in the Tariff.
The capacity offered herein is not subject to an existing ROFR. Contractual ROFR will not be offered under this open season.
Length of Bidding Process – The bidding process will begin on Wednesday January 21, 2026, at 09:00AM CT and conclude on Wednesday January 21, 2026, at 02:00 PM CT. All bids must be submitted to Columbia prior to the conclusion of the bidding process.
Participation in the Bidding Process – All bids submitted for this posted capacity will be treated in a nondiscriminatory manner under this open season. To participate in the bidding process, interested parties must send an email with bid terms to:
Diana_Roberts@TCEnergy.com
capacityrequest@TCEnergy.com
All bids should refer to Open Season # 2026-0121 – MC FTS Milford to Martins Creek
A bid must contain all of the applicable information required by the attached Bid Form at the end of this posting. Bidders must satisfy creditworthiness in accordance with Columbia’s Tariff. A potential shipper may submit multiple bids, each higher than its preceding bid, for all or any portion of the capacity or term of service made available by Columbia in this open season. Bidders may bid on Package 1, Package 2, or both packages. If a bidder submits multiple bids, Columbia will consider only the last, highest bid submitted by bidder for the purpose of awarding capacity offered in this open season. Bidder shall specify that they are bidding the Total Effective Rate (defined above) or a monthly reservation rate (or other firm or demand charge(s), if applicable, herein referred to collectively as “Reservation Charge”) it is bidding for the service. The rate for the monthly Reservation Charge shall be expressed as a monthly rate per dth and shall be expressed to the nearest thousandth of one dollar ($0.000). For bidders proposing a Reservation Charge or other form of revenue guarantee which exceeds the current applicable Recourse Rate during all or any portion of the term proposed by the bidder, the net present value (“NPV”) calculated for the bid may not exceed an NPV that is calculated assuming that the Recourse Rate shall be in effect during the full term proposed by the bidder, in place of the reservation rate(s) or other revenue guarantee(s) proposed by the bidder. Any bid, other than a contingent bid, not withdrawn before the close of the bidding period will be binding.
Assessing Bids- Columbia reserves the right to reject any bids that do not conform to the primary points or terms listed herein or any bids at a discounted rate. Columbia reserves the right to reject any bid that is incomplete or includes conditions or provisions that Columbia determines, in its reasonable discretion, to be unacceptable. The NPV for each package of any bids submitted in this open season will be determined in accordance with Section 4.4(b) of Columbia’s Tariff. Bids will be assessed based on the total NPV to Columbia as determined by adding the individual NPV for bids on Package 1 and Package 2 offered under this open season (“Total NPV”). If a shipper does not bid for both packages in this open season, the NPV for the package not bid on will be 0. Columbia reserves the right to reject any bid or request that contains modifications to the Bid Form or conflicts with Columbia’s Tariff. Columbia has the right to clarify bids.
Total NPV is calculated as (NPV of Package 1) + (NPV of Package 2). Individual package NPVs will be calculated as follows:
Package NPV = ? n [R*(1 / (1+i) ^ n)]
? n = Summation of months 1 through n
n = term in months of applicable package
R = Incremental monthly revenue for the applicable package (Package Bid Rate*Package Contract Quantity)
i = Monthly Discount Rate (the current FERC quarterly rate which can be found at https://www.ferc.gov/enforcement-legal/enforcement/interest-calculation-rates-and-methodology)
Awarding of Capacity – Columbia will notify successful bidders no later than 04:00 PM CT, Wednesday January 21, 2026.
Any awards of available capacity will be made independently based upon objective criteria and the NPV of the bids to Columbia. Columbia will award capacity posted in this open season in accordance with Sections 4.4(b) and (e) of Columbia’s Tariff. If two or more bidders submit acceptable bids of an equal NPV, and which are conforming to the terms of this notice, and there is insufficient capacity available to serve all such bidders, then Columbia shall determine the successful bidder based on the order in which the bids were received.

Notice Text
Columbia Gas Transmission, LLC (TCO) notifies shippers the Operational Flow Order (OFO) impacting receipt points in Market Areas 26, 30, 35, 41 and 42 is lifted effective Intraday Gas Day Tuesday, September 8, 2026.
TCO reserves the right to reinstate the OFO as operationally necessary. As a reminder, the Pre-OFO (Notice ID 26203010) remains in effect.
Please contact your Customer Services Representative with any questions.
***Previous Posting***
Pursuant to the provisions of Section 17 of the General Terms and Conditions of its FERC Gas Tariff, Columbia Gas Transmission, LLC (TCO) is issuing an Operational Flow Order ("OFO") to Shippers under all transportation rate schedules with receipts in Market Areas 26, 30, 35, 41, and 42 to protect the operational integrity of TCO’s system and its ability to meet its firm service obligations.
As explained in Pre OFO (Notice ID 26205016), due to mild weather forecasts, anticipated lower market demand, higher storage and line pack levels, and the level of production received in Market Areas 26, 30, 35, 41, and 42, physical receipts must be equal to or less than scheduled receipts in order to maintain system integrity and provide reliable firm service. Consequently, TCO cannot allow excess receipts at any receipt point in these Market Areas.
Therefore, TCO is issuing the following Operational Flow Order (OFO):
1. The Time and Date of Issuance of this OFO is Friday, September 4, 2026, at 8:05 AM ET.
2. The OFO will become effective for Gas Day Saturday, September 5, 2026.
3. This OFO will continue in duration until TCO issues further notice of termination of this OFO.
4. The Shippers impacted by this OFO are those scheduling receipts of gas in Market Areas 26, 30, 35, 41, and 42 whose physical receipts are not less than or equal to their scheduled receipts during a Gas Day.
5. Pursuant to the OFO, the following actions must be taken:
During the period this OFO is in effect, impacted shippers must align scheduled quantities with physical quantities in Market Areas 26, 30, 35, 41, and 42, which may require communication with upstream operators. Shippers must remain in balance at the start of, and throughout, each Gas Day, beginning Saturday, September 5, 2026, and continuing until further notice. Receipt points must be balanced such that actual receipts into Market Areas 26, 30, 35, 41, and 42 must be less than or equal to the scheduled receipt quantities into these areas unless otherwise mutually agreed on a nondiscriminatory basis.
6. The justification for issuing the OFO is as set forth above.
7. Additional information: Shippers who do not comply will be subject to penalties in accordance with Section 19.3 of TCO’s FERC Gas Tariff. Shippers are encouraged to stay coordinated with upstream suppliers regarding changes in physical flow for the duration of the OFO.
If a penalty is assessed, the penalty will be based on all quantities in aggregate in violation of the OFO in excess of a tolerance of 5% of scheduled receipt quantities or 5,000 Dth whichever is higher. This tolerance will be in effect during the OFO unless revised through an update to this notice. Penalties will be based on the shipper’s prorated share of the total excess quantities above the tolerance at the receipt point for that day at the higher of: (i) a price per Dth equal to three times the midpoint of the range of prices reported for "Columbia Gas, Appalachia" as published in Platts Gas Daily price survey for the days on which the OFO is issued, or (ii) a price per Dth equal to 150 percent of the highest midpoint posting for either: Mich Con City-gate, Transco, Zone 6 Non-N.Y., or Texas Eastern, M-2 Receipts as published in Platts Gas Daily price survey for the days on which the OFO is issued. Penalties under Section 19.3 (ii) will only be assessed on days in which the daily spot price of gas exceeds three times the midpoint of the range of prices reported for "Columbia Gas, Appalachia."
Please contact your Customer Services Representative with any questions.

Notice Text
Columbia Gas Transmission, LLC (TCO) notifies customers of upcoming maintenance on Line SM-80 Loop in West Virginia beginning Thursday, September 10, 2026, and continuing through September 26, 2026. During the maintenance, TCO will utilize the temporary internal constraint Ceredo West MA19 (CEREWEST), which has been enabled in TC eConnects (Notice ID 26196010).
Based on forecasted operating conditions, TCO currently anticipates CEREWEST will be restricted to zero non-firm effective Timely Cycle for Thursday, Gas Day September 10, 2026, and continuing until further notice.
TCO reminds customers it may become necessary to reduce the capacity through CEREWEST to a level as low as 1,400,000 Dth Total Capacity (zero non-firm). TCO encourages customers to reference the Daily Capacity Posting for the specific capacity through CEREWEST each day during the maintenance.
Reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 38 of TCO’s FERC Gas Tariff (“Tariff”). However, TCO will only issue RCCs if TCO is unable to schedule or deliver primary firm nominated capacity as a result of the outage. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day average usage quantity less any scheduled quantities on the contract.
Please contact your Customer Services Representative with any questions.

Columbia Gas Transmission, LLC (TCO) notifies customers of upcoming pipeline maintenance on Line SM-80 in West Virginia scheduled to begin on Wednesday, September 9, 2026, through Saturday, September 26, 2026. During the maintenance, TCO will be utilizing the temporary internal constraint Ceredo West MA19 (CEREWEST).
Due to the utilization of CEREWEST, TCO has configured the temporary constraint in TC eConnects. This will allow customers to view CEREWEST on the Internal Constraint Rights screen, as well as the Operationally Available Capacity screen on Informational Postings.
Based on forecasted operating conditions during the maintenance, TCO does not currently anticipate any reduction to firm nominations through CEREWEST. However, based on operating conditions, including the logistics involved with the performance of work, it may become necessary to reduce the capacity through CEREWEST to a level as low as 1,400,000 Dth Total Capacity (zero non-firm).
Customers are encouraged to monitor the Construction and Maintenance Schedule for any non-firm impacts and the Daily Capacity Posting for specific capacity settings each day of the outage.
Reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 38 of TCO’s FERC Gas Tariff (“Tariff”). However, TCO will only issue RCCs if TCO is unable to schedule or deliver primary firm nominated capacity as a result of the outage. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day average usage quantity less any scheduled quantities on the contract. By means of this notice, TCO is establishing which specific Gas Days will be included when determining a shipper’s 7-day average usage quantity pursuant to the provisions in the Tariff.

Diana_Roberts@TCEnergy.com
capacityrequest@TCEnergy.com
All bids should refer to Open Season # 2026-0123- H FTS Milford to Hanover
A bid must contain all of the applicable information required by the attached Bid Form at the end of this posting. Bidders must satisfy creditworthiness in accordance with Columbia’s Tariff. A potential shipper may submit multiple bids, each higher than its preceding bid, for all or any portion of the capacity or term of service made available by Columbia in this open season. Bidders may bid on Package 1, Package 2, or both packages. If a bidder submits multiple bids, Columbia will consider only the last, highest bid submitted by bidder for the purpose of awarding capacity offered in this open season. Bidder shall specify that they are bidding the Total Effective Rate (defined above) or a monthly reservation rate (or other firm or demand charge(s), if applicable, herein referred to collectively as “Reservation Charge”) it is bidding for the service. The rate for the monthly Reservation Charge shall be expressed as a monthly rate per dth and shall be expressed to the nearest thousandth of one dollar ($0.000). For bidders proposing a Reservation Charge or other form of revenue guarantee which exceeds the current applicable Recourse Rate during all or any portion of the term proposed by the bidder, the net present value (“NPV”) calculated for the bid may not exceed an NPV that is calculated assuming that the Recourse Rate shall be in effect during the full term proposed by the bidder, in place of the reservation rate(s) or other revenue guarantee(s) proposed by the bidder. Any bid, other than a contingent bid, not withdrawn before the close of the bidding period will be binding.
Assessing Bids- Columbia reserves the right to reject any bids that do not conform to the primary points or terms listed herein or any bids at a discounted rate. Columbia reserves the right to reject any bid that is incomplete or includes conditions or provisions that Columbia determines, in its reasonable discretion, to be unacceptable. The NPV for each package of any bids submitted in this open season will be determined in accordance with Section 4.4(b) of Columbia’s Tariff. Bids will be assessed based on the total NPV to Columbia as determined by adding the individual NPV for bids on Package 1 and Package 2 offered under this open season (“Total NPV”). If a shipper does not bid for both packages in this open season, the NPV for the package not bid on will be 0. Columbia reserves the right to reject any bid or request that contains modifications to the Bid Form or conflicts with Columbia’s Tariff. Columbia has the right to clarify bids.
Total NPV is calculated as (NPV of Package 1) + (NPV of Package 2). Individual package NPVs will be calculated as follows:
Package NPV = ? n [R*(1 / (1+i) ^ n)]
? n = Summation of months 1 through n
n = term in months of applicable package
R = Incremental monthly revenue for the applicable package (Package Bid Rate*Package Contract Quantity)
i = Monthly Discount Rate (the current FERC quarterly rate which can be found at https://www.ferc.gov/enforcement-legal/enforcement/interest-calculation-rates-and-methodology)
Awarding of Capacity – Columbia will notify successful bidders no later than 01:00 PM CT, Tuesday January 27, 2026.
Any awards of available capacity will be made independently based upon objective criteria and the NPV of the bids to Columbia. Columbia will award capacity posted in this open season in accordance with Sections 4.4(b) and (e) of Columbia’s Tariff. If two or more bidders submit acceptable bids of an equal NPV, and which are conforming to the terms of this notice, and there is insufficient capacity available to serve all such bidders, then Columbia shall determine the successful bidder based on the order in which the bids were received.

A bid must contain all of the applicable information required by the attached Bid Form at the end of this posting. Bidders must satisfy creditworthiness in accordance with Columbia’s Tariff. A potential shipper may submit multiple bids, each higher than its preceding bid, for all or any portion of the capacity or term of service made available by Columbia in this open season. Bidders may bid on Package 1, Package 2, or both packages. If a bidder submits multiple bids, Columbia will consider only the last, highest bid submitted by bidder for the purpose of awarding capacity offered in this open season. Bidder shall specify that they are bidding the Total Effective Rate (defined above) or a monthly reservation rate (or other firm or demand charge(s), if applicable, herein referred to collectively as “Reservation Charge”) it is bidding for the service. The rate for the monthly Reservation Charge shall be expressed as a monthly rate per dth and shall be expressed to the nearest thousandth of one dollar ($0.000). For bidders proposing a Reservation Charge or other form of revenue guarantee which exceeds the current applicable Recourse Rate during all or any portion of the term proposed by the bidder, the net present value (“NPV”) calculated for the bid may not exceed an NPV that is calculated assuming that the Recourse Rate shall be in effect during the full term proposed by the bidder, in place of the reservation rate(s) or other revenue guarantee(s) proposed by the bidder. Any bid, other than a contingent bid, not withdrawn before the close of the bidding period will be binding.
Assessing Bids- Columbia reserves the right to reject any bids that do not conform to the primary points or terms listed herein or any bids at a discounted rate. Columbia reserves the right to reject any bid that is incomplete or includes conditions or provisions that Columbia determines, in its reasonable discretion, to be unacceptable. The NPV for each package of any bids submitted in this open season will be determined in accordance with Section 4.4(b) of Columbia’s Tariff. Bids will be assessed based on the total NPV to Columbia as determined by adding the individual NPV for bids on Package 1 and Package 2 offered under this open season (“Total NPV”). If a shipper does not bid for both packages in this open season, the NPV for the package not bid on will be 0. Columbia reserves the right to reject any bid or request that contains modifications to the Bid Form or conflicts with Columbia’s Tariff. Columbia has the right to clarify bids.
Total NPV is calculated as (NPV of Package 1) + (NPV of Package 2). Individual package NPVs will be calculated as follows:
Package NPV = ? n [R*(1 / (1+i) ^ n)]
? n = Summation of months 1 through n
n = term in months of applicable package
R = Incremental monthly revenue for the applicable package (Package Bid Rate*Package Contract Quantity)
i = Monthly Discount Rate (the current FERC quarterly rate which can be found at https://www.ferc.gov/enforcement-legal/enforcement/interest-calculation-rates-and-methodology)
Awarding of Capacity – Columbia will notify successful bidders no later than 01:00 PM CT, Friday January 23, 2026

If two or more bidders submit acceptable bids of an equal NPV, and which are conforming to the terms of this notice, and there is insufficient capacity available to serve all such bidders, then Columbia shall determine the successful bidder based on the order in which the bids were received.
