Welcome to!  We always review the country’s interstate natural gas pipeline companies for their most recent critical postings and bring you information about changes in pipeline operating conditions. 

Plus, we will update you on the latest publicly released news from major energy companies and provide the extended temperature forecast for the next few weeks from the National Weather Service, too.  


From the US Energy Information Administration, working gas in storage was estimated at 1,653 Bcf as of Friday, May 10, 2019. This represents a net increase of 106 Bcf from the previous week.

Stocks were 130 Bcf higher than last year at this time and 286 Bcf below the five-year average of 1,939 Bcf. At 1,653 Bcf, total working gas is within the five-year historical range.


OG& E Chairman, President and CEO Sean Trauschke today told the company’s shareholders that the company is “strong and built for the long term.” Speaking at the company’s annual meeting, Trauschke said he was pleased with the performance of OG&E, Oklahoma’s largest investor-owned utility, and Enable Midstream, in which the company owns interest, as both had contributed to the company’s ability to invest in its customers, and maintain utility rates that are 31 percent below the national average.

“2018 will be the benchmark the company uses to gauge future performance. OG&E completed its largest ever investment program, wrapping up more than $6 billion of infrastructure investment since 2011, on time, under budget and while receiving recognition as the safest utility in the Southeastern Electric Exchange,” Trauschke said. “At Enable, we’re seeing continued solid operational and financial results, while volumes are increasing across all of their business segments.”

Looking ahead, he said the company will continue to focus on growing the business through an enhanced customer experience at affordable rates. “The new assets we’ve put into operation have increased fleet resiliency for customer benefit. We will continue to leverage our smart meters and technology that increases reliability and reduces outage response and restoration times.”

OGE Energy is the parent company of Oklahoma Gas and Electric Company, a regulated electric utility serving approximately 852,000 customers in Oklahoma and western Arkansas. In addition, OGE holds a 25.5 percent limited partner interest and a 50 percent general partner interest of Enable Midstream Partners, LP.


On Tuesday, Sempra Energy celebrated the completion of construction of Train 1 of the Cameron LNG export project in Hackberry, La., with a group of international, federal, state and local officials, including the U.S. president and members of the U.S. administration. The celebratory visit coincided with today’s announcement that Cameron LNG is producing liquefied natural gas (LNG) from the first liquefaction train of the three-train facility, a major commissioning milestone.

Sempra Energy set a goal in 2018 to become the largest developer of North American LNG export infrastructure, targeting 45 million tonnes per annum of LNG export capacity to serve global markets. 

“With a renaissance in domestic energy production, Sempra Energy is pleased to advance America as one of the world’s largest exporters of LNG,” said Jeffrey W. Martin, chairman and CEO of Sempra Energy.  “We are committed to providing a cleaner fuel source to the global markets while supporting job creation right here at home.”

Cameron LNG Phase 1 is one of five LNG projects Sempra Energy is developing in North America. Other projects under development include Cameron LNG Phase 2, previously authorized by the Federal Energy Regulatory Commission (FERC), which could include up to two additional liquefaction trains and up to two additional LNG storage tanks; Port Arthur LNG in Texas, which recently was approved by FERC; and Energía Costa Azul LNG Phase 1 and Phase 2 in Mexico.


Several interstate natural gas pipeline companies have posted notices warning customers that there isn’t much room left for excess gas supplies heading into the weekend. Let’s review the latest EBB postings:

ANR Pipeline:

ANR will begin planned maintenance at the Brownsville (Tennessee) Compressor Station located in the Southeast Southern Segment (Zone 2). The total Brownsville Southbound (LOC #1260569) capacity will be reduced by the following:

230-MMcf/d (leaving 900-MMcf/d available) 5/20-5/22

Based on current nominations, it is anticipated that this posting may result in the capacity allocation reduction of IT, Firm Secondary and possibly a portion of Firm Primary volumes. Since ANR anticipates that this restriction may impact its ability to deliver all nominated Firm Primary services, ANR will apply the Reservation Charge Crediting Mechanism of Section 6.36.4 as necessary. This posting will be updated as more information becomes available. Additionally, customers may experience lower than normal line pressures south of the Brownsville Compressor Station.

The estimated impact to Firm Primary is as follows:

17% – Based on the Current Net Southbound Shipper Nominations
20% – Based on the Current Southbound Contracted MDQ

Columbia Gas Transmission:

Columbia Gas Transmission, LLC (TCO) reminds customers of upcoming pigging on MXP Line 100 (previously posted on the Construction and Maintenance Schedule) beginning Tuesday, May 21, 2019 through Friday, May 24, 2019.   Due to the pigging, the below impact is anticipated for the following Gas Days: 

643131 – Corral:

May 21, 2019 – 0 Non-Firm

SHERWODB – Sherwood B MA42:

May 21, 2019 – 940,000 Total Capacity


May 22, 2019 – 1,720,000 Total Capacity

May 23, 2019 – 1,600,000 Total Capacity

May 24, 2019 – 1,600,000 Total Capacity 

Based on current scheduled volumes, there are no anticipated reductions to firm service. As a reminder, the impacted capacities will not be reinstated until the work is complete, which may impact Timely and Evening Cycle nominations for Gas Day May 25, 2019. 

Reservation charge credits will be determined per the process set forth in the General Terms and Conditions, Section 38 of TCO’s FERC Gas Tariff.  Any shipper eligible for reservation charge credits should review this section and comply with the described process to ensure receipt of any credits.  

Dominion Energy Questar Pipeline:

Effective Gas Day May 16, 2019, Timely Cycle and continuing until further notice, Dominion Energy Questar Pipeline (DEQP) will not allow in-kind imbalance payback to the pipeline and is requiring shippers and point operators to have production volumes aligned with scheduled nominations.

This notice is due to the high inventory in DEQP’s Clay Basin balancing account and current pipeline conditions resulting in minimal line pack available for balancing.

Customers with questions should contact their DEQP representative or call the Customer Service Hotline at (801)324-5200.

Gas Transmission Northwest (GTN):

Effective immediately, GTN Pipeline is issuing an OFO watch. GTN Pipeline is concerned about the operational integrity of its system as a result of high line pressures.

The OFO watch is in effect through gas day Tuesday May 21st, in order to allow for GTN pipeline system to regain its operational integrity. GTN has limited flexibility to manage imbalances and strongly encourages all shippers manage their system requirements to ensure the matching of receipts and deliveries daily.

The latest six-to-ten day temperature forecast from the National Weather Service continues to project that above average temperatures will dominate the eastern US through May 26.  The West Coast and Rockies will continue to see below normal weather conditions through late this month.

Thanks for joining us at!  We’ll be back on Monday to bring you the publicly sourced natural gas pipeline and energy news for you along with an updated weather outlook for the coming week. 

Please tell a friend in the natural gas scheduling and transportation business about us.   Have a great weekend!

Monday, May 13, 2019

Welcome to  A variety of springtime weather conditions has caused a late season snowfall in the Rockies and northern tier of states while a large area of severe weather and flooding caused issues in the South.  Meanwhile, spot natural gas prices seem to be stuck in neutral as we start the new week.   

Today, we’ll also review the latest interstate pipeline company critical notices, provide an update on latest energy news, and cover the latest National Weather Service temperature forecast into late May, too.


From the US Energy Information Administration’s “Natural Gas Weekly Update” publication:

Net injections to working gas totaled 85 billion cubic feet (Bcf) for the week ending May 3. Working natural gas stocks are 1.547 Tcf, which is 16% lower than the five-year (2014–18) average for this week.

At the New York Mercantile Exchange (Nymex), the price of the June 2019 contract was nearly static at $2.62/MMBtu on Monday.  The price of the 12-month strip averaging June 2019 through May 2020 futures contracts is now about $2.75/MMBtu.

Strong natural gas production, as well as rapidly-rising demand, resulted in record-high production of natural gas plant liquids, which reached 4.7 million barrels per day (b/d) in February 2019. Growth in natural gas plant liquids production was led by ethane, which was nearly 130,000 barrels per day (b/d) higher than in the previous month.

The natural gas plant liquids composite price at Mont Belvieu, Texas, fell by 43¢/MMBtu, averaging $5.69/MMBtu for the week ending May 8. The price of natural gasoline, ethane, propane, butane, and isobutane all fell, by 2%, 5%, 8%, 12%, and 13%, respectively.

According to Baker Hughes, for the week ending Tuesday, April 30, the natural gas rig count decreased by three to 183. The number of oil-directed rigs rose by two to 807. The total rig count decreased by one and now stands at 990.


OG&E, a subsidiary of Oklahoma City-based OGE Energy Corp., announced that the Oklahoma Corporation Commission (OCC) today unanimously approved the company’s preapproval application to acquire the AES Shady Point plant near Poteau, Oklahoma, and the Oklahoma Cogeneration LLC facility in Oklahoma City.

The company, which filed its preapproval request in December 2018, is expected to pay approximately $53 million for the two plants – both of which have served OG&E customers for several decades under federally mandated power purchase agreements.

“These acquisitions create a win-win on multiple fronts,” said OG&E spokesman Brian Alford. “Our customers will save tens of millions of dollars each year by eliminating costly, federally mandated agreements. The Shady Point acquisition will help maintain grid stability as growth continues in eastern Oklahoma and western Arkansas. It also ensures many jobs will be preserved in an economically challenged region. The Oklahoma Cogen acquisition will help ensure the facility’s natural-gas-fired capacity will continue to support reliability and resiliency in the ever-growing Oklahoma City-metro area. And, we’ll see a further reduction in power plant air emissions as a result of the acquisitions.”

Shady Point has a generation capacity of 360MW and Oklahoma Cogeneration has a capacity of 146MW.


On Friday, Weatherford International plc (“Weatherford” or the “Company”) announced that it has executed a restructuring support agreement (the “Restructuring Agreement”) with a group of its senior noteholders (the “Ad Hoc Noteholder Group”) that collectively holds or controls approximately 62% of the Company’s senior unsecured notes. The proposed comprehensive financial restructuring would significantly reduce the Company’s long-term debt and related interest costs, provide access to additional financing and establish a more sustainable capital structure.

Weatherford expects to implement the Restructuring Agreement through a “pre-packaged” Chapter 11 process and expects to file U.S. chapter 11 and Irish examinership proceedings (collectively, the “Cases”). As part of this process, Weatherford intends to continue engaging in discussions with, and begin soliciting votes from, its creditors in connection with a proposed Plan of Reorganization prior to filing.

“During the past year, we have been executing a company-wide transformation to fundamentally improve the way we operate our business and to strengthen Weatherford for the long run,” said Mark A. McCollum, President and CEO of Weatherford. 

Under the terms of the Restructuring Agreement, the Company’s unsecured noteholders would exchange approximately $7.4 billion of senior unsecured notes for approximately 99% of the equity in the Company and $1.25 billion of new tranche B senior unsecured notes (the “Tranche B Notes”).

The Restructuring Agreement contemplates the Company will continue operating its businesses and facilities without disruption to its customers, vendors, partners or employees and that all trade claims against the Company (whether arising prior to or after the commencement of the Chapter 11 Cases) will be paid in full in the ordinary course of business.


We’re off to a relatively quiet start to the work week Monday along the interstate natural gas pipeline grid.

East Tennessee Natural Gas:

As previously posted, East Tennessee Natural Gas (ETNG) has limited operational flexibility to manage imbalances. As a result, effective May 13, 2019, ETNG requires all delivery point operators on the system to keep actual daily takes out of the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position unless otherwise coordinated with your operations account representative. All receipt point operators on the system are required to keep actual receipts into the system equal to or less than scheduled quantities regardless of their cumulative imbalance position unless otherwise coordinated with your operations account representative.

This notice will remain in effect until further notice.

Natural Gas Pipeline Company of America (NGPL):

Effective for gas day Tuesday, May 14, 2019, and continuing until further notice, Natural is at operating capacity for northbound flow through Compressor Station 106 located in Gage County, Nebraska (Segment 11 of Natural’s Midcontinent Zone).  AOR/ITS and Secondary out-of-path Firm transports are at risk of not being fully scheduled. 

Natural Gas Pipeline Company of America, LLC also conducted its customer meeting today, May 13, 2019.  In an effort to keep all customers informed relative to items discussed, the presentation slides from this meeting have been posted to the internet and can be accessed by clicking on the following link:


The National Weather Service six-to-ten day temperature forecast through May 23 shows temperature extremes on both coasts of the United States.  The eastern half of the country will see warmer than seasonal weather, while the West Coast and Rocky Mountain regions are expecting significantly colder than normal temperatures for the period.

That’s all for this Monday edition of  We’ll return Thursday to provide an update on the interstate gas pipeline conditions expected for the weekend.

Edition 25 – Thursday, December 20, 2018

Like George Bailey on the bridge in It’s A Wonderful Life, the natural gas business is hoping for a wintertime miracle to give another boost to natural gas prices for the coming year.

Welcome back to!   We take care of wrapping up the packages of natural gas news and gas pipeline bulletin board postings for you – all for FREEHo, Ho, Ho!

Before we take a look at a large number of critical notices from the interstate pipeline companies, let’s check out some of the latest natural gas news today:


From the US Energy Information Administration‘s “Weekly Natural Gas Storage Report“, working gas in storage decreased by 141 Bcf from the previous week.   Natural gas stocks were 720 Bcf or 20.6% below the five-year average.


Oklahoma Gas & Electric, the utility subsidiary of OGE Energy Corp., announced today that it will acquire two existing power plants to meet customers’ energy needs. The plants will replace capacity currently provided by power purchase contracts set to expire in 2019.

The company announced it will acquire the Shady Point plant near Poteau, Oklahoma, and the Oklahoma Cogeneration plant in Oklahoma City.

The Shady Point facility is a 360 MW coal- and natural gas-fired plant utilizing circulating fluidized bed boilers that produce lower emissions due to their design features and emissions controls.

The Oklahoma Cogeneration facility is a 146 MW natural gas-fired combined-cycle plant.

The company will pay approximately $53 million for the two plants, which currently serve OG&E customers.

“In the past five years, we’ve completed several critical projects that advance our commitment to deliver energy reliably and affordably to customers in an environmentally responsible way.  Today’s announcement builds on that commitment,” said OGE Energy Corp. Chairman, President and CEO Sean Trauschke. “Our diverse energy portfolio of natural gas, wind, solar and coal gives us the versatility to meet a variety of economic and environmental needs. The result is our electric rates are 29 percent below the national average, which is a driver of economic development, and OGE is among industry leaders in emissions reduction performance.


ENGIE Resources today announced the acquisition of Plymouth Rock Energy based in Woodmere, NY. The transaction, which has received approval from the Federal Energy Regulatory Commission and became effective December 19, 2018, will enable ENGIE Resources to expand its natural gas and electricity presence in seven states and by more than 20,000 customers.

The combined organization expects to benefit from complementary products, geographies, and systems in addition to shared information technology and billing and service economies.


The interstate gas pipeline network is getting ready for the long Christmas break by posting a number of critical notices to shippers and customers.  Let’s take a look:

Algonquin Gas Transmission:

In order to maintain the operational integrity of the system, Algonquin Gas Transmission, LLC (AGT) is issuing an Operational Flow Order (OFO) pursuant to Section 26 of the General Terms and Conditions of AGT’s FERC Gas Tariff effective 9:00 AM CCT, December 24, 2018, to all parties, with the exception of those Operational Balancing Agreements required by FERC regulations, on the AGT system.

This OFO does not affect the ability of AGT to receive or deliver quantities of gas for scheduled nominations to any customer or pipeline.

During the effectiveness of this OFO, all parties must be balanced such that actual deliveries of gas out of the system must be equal to or less than scheduled deliveries. The penalty shall apply to each dekatherm of actual delivery quantities that exceeds the greater of 4,000 Dth or 104% of scheduled delivery quantities.  The penalty will be equal to three times the daily Platts Gas Daily “Daily Price Survey” posting for the High Common price for”Algonquin, city-gates” for the day on which such violation occurred as indicated in AGT’s General Terms and Conditions Section 26.8. In addition, AGT will not permit retroactive nominations to avoid an OFO penalty.

This OFO will remain in effect until further notice.

Columbia Gulf Transmission:

Effective December 20, 2018 for the ID1 cycle, the Kinder Morgan La. interconnect, Meter 4206 is now designated as bidirectional and available for delivery nominations on Columbia Gulf Transmission, LLC (CGT).  This meter is located in Evangeline Parish, LA on CGT’s Mainline.  

Dominion Energy Questar Pipeline

Dominion Energy Questar Pipeline’s fuel reimbursement rate is changed for January 1,2019 from 1.87% to 1.57% pending FERC approval by the end of December. If there are any changes to the rate, the approved rate will be reposted.

East Tennessee Natural Gas:

Line 3100 Outage Update

Enbridge is working with PHMSA towards a timely in-service of East Tennessee Natural Gas’ (ETNG) 22-inch natural gas pipeline impacted by the incident that occurred in Pleasant Shade, Tennessee, on December 15, 2018.

Safety is a fundamental principle in everything we do and we are ensuring all construction and restoration operations are completed safely.  We continue to refine our return to service plan, and currently do not have an estimated time of restoration. 

Enbridge is committed to bringing the affected section of its East Tennessee Natural Gas system back to operation in a safe manner.  We will provide further updates as future milestones are achieved or as circumstances warrant.

El Paso Natural Gas: 

Pipeline Conditions – Weekend Linepack Concerns 

Currently EPNG linepack is within acceptable limits going into the holiday weekend. However, EPNG is concerned that the forecasted milder weather across our service area could result in a high linepack situation. 

Customers are encouraged to review their transport to ensure that their flowing quantities are aligned with their scheduled supplies.   

Delivery point operators are encouraged to take gas according to their scheduled quantities. If the situation warrants, EPNG will declare an SOC for a PACK condition. 

Supply operators are encouraged to maintain their deliveries into the EPNG system at their scheduled rates. 

Washington Ranch is on maximum injection. 

Payback to the system, such as Make-Up Receipt (MR) transactions, may be limited or denied due to operational concerns related to the potential for a high linepack condition. 

Enable Gas Transmission:


New Information Posted December 19th, 2018

This Operational Alert is being issued pursuant to Section 20, GT&C, of EGT’s Tariff to notify shippers of planned maintenance at EGT s Byars Lake Compressor Station.

Effective February 6, 2019, at 9:00 a.m. and continuing through February 7, 2019 (previously January 9 through 10), EGT will conduct planned maintenance on its Byars Lake Compressor Station, located in McClain County, Oklahoma and in EGTs West 2 Pooling Area.  During this maintenance, capacity through EGT’s Allen Compressor Station will be limited to approximately 780,000 Dth/d; point operators will experience higher pressure.

Based on current nominations, EGT expects impacts to its services, including potential impacts to firm service.  During the planned maintenance, shippers whose receipts are in the West 1 and West 2 pooling areas West of the Allen Compressor Station should nominate point to point in order to maintain the highest priority level of service.

Gulf South Pipeline:

Olla (Louisiana) Compressor Station Maintenance – Update

Effective date:  December 20, 2018               End Date:  December 28, 2018

For the Marksville Deliveries Scheduling Group, capacity could be impacted by as much as 100,000 dth/d for the duration of the maintenance.

Northern Natural Gas:

In an effort to provide timely and useful information that may impact customers’ decisions regarding nominated volumes, and to assist shippers in scheduling their transportation and storage services, Northern is providing advance notice of the Carlton Sourcing Obligation, System Underrun Limitation (SUL), and System Overrun Limitation (SOL) for the holiday weekend.

Based on temperatures that are currently forecast for the Market Area throughout the holiday weekend, the following system conditions will be in effect to ensure adequate line pack and delivery pressures.

The Carlton Sourcing Obligation will be as follows:

Gas Day Saturday, December 22, 2018, will be 0%

Gas Day Sunday, December 23, 2018, will be 0%

Gas Day Monday, December 24, 2018, will be 0%

Gas Day Tuesday, December 25, 2018, will be 0%

Gas Day Wednesday, December 26, 2018, will be 0% 

SUL and SOL status for both the Market and Field Areas will be as follows:  No SUL or SOL 

Holiday Weekend Temperatures Projected to be Warmer-Than-Normal

The likelihood of storage injection allocations is at a higher probability for the extended holiday weekend due to the forecast of warmer than normal temperatures. These conditions could lead to the allocation of interruptible storage injections, including firm deferred delivery overrun injections.

Although Northern does not anticipate calling an SUL, Northern may be required to allocate overperforming receipt points and/or underperforming delivery points located in the Permian basin to actual flowing volumes during an intraday nomination cycle in order to maintain adequate supply/market balance. As performance improves at these receipt and delivery points, allocations would be lifted.

Northwest Pipeline:

Effective December 21-23, 2018, Jackson Prairie will be undergoing maintenance. Nominations that net to an injection or withdrawal of 50,000 Dth/d will be accepted. Northwest requests that customers stay on rate to avoid the issuance of an Entitlement.

Northwest will schedule up to 10,000 Dth at $0.10 for both Park and Loan at JP for December 21-23. 

Northwest is NOT allowing interruptible in or out of JP December 21-23.

Northwest is asking Shippers to voluntarily reduce nomination through the Rangely compressor station to avoid the issuance of an OFO over the holidays. Operational capacity is 370,000 Dth/d. If nominations exceed 370,000 Dth/d Northwest could issue an OFO.

Northwest encourages you to continue scheduling your supply so that sufficient gas is being delivered to Northwest to cover your market.

Northwest Pipeline reserves the right to cut secondary gas to protect the operational integrity of its pipeline. This includes cutting secondary gas at any compressor in a constrained corridor; moving balancing gas to and from Clay Basin and Jackson Prairie; or to minimize OFOs for primary irm shippers.

PG&E – California Gas Transmission:

Due to the completion of maintenance on Line 300 A/B, pipeline inventory limits will be restored to the following ranges starting on today’s gas day, December  20, 2018:

Total System Demand above 2,800 MMcf will change back to 4,350-4,000 MMcf from 4,200-3,850 MMcf

Total System Demand at 2,800 MMcf or below will change back to 4,300-3,900 MMcf from 4,150-3,750 MMcf.

Southern Star Central Pipeline:

Line Segment 130 Force Majeure (UPDATE #13):

Southern Star Central Gas Pipeline (Southern Star) posted a Force Majeure Update on Line Segment 130 Tuesday, June 19, 2018. Southern Star continues working to fully restore service for Line Segment 130.

Additional work has been completed, Effective TIM Cycle Gas Day December 20, 2018, and Southern Star will increase capacity at the Kansas Hugoton Receipt constraint to 383,000 Dth/d.

Texas Eastern Transmission:

TE Imbalance Notice – UPDATE

As previously posted, Texas Eastern (TE) has limited operational flexibility to manage imbalances. As result, effective immediately, TE requires all delivery point operators in Market Area Zones M1-24 and M2-24 to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance position unless otherwise coordinated with your operations account representative.
