ERCOT Texas Fall Grid Forecast outlines ample power supply, planned maintenance outages, and grid reliability, citing PUC oversight and Gov. Abbott's remarks, with seasonal assessment noting mild demand yet climate risks and conservation alerts.

Key Points

ERCOT's seasonal outlook for Texas on fall power supply, outages, and reliability expectations under PUC oversight.

✅ Projects sufficient supply in October and November

✅ Many plants scheduled offline for maintenance

✅ Notes PUC oversight and Abbott's confidence

Gov. Greg Abbott said Tuesday that the Texas power grid is prepared for the fall months and referenced a new seasonal forecast by the state’s grid operator, which typically does not draw much attention to its fall and spring grid assessments because of the more mild temperatures during those seasons.

Tuesday’s new forecast by the Electric Reliability Council of Texas showed that there should be plenty of power supply to meet demand in October and November. It also showed that many Texas power plants are scheduled to be offline this fall for maintenance work. Texas power plants usually plan to go down in the fall and spring for repairs to improve reliability ahead of the more extreme temperatures in winter and summer, when Texans crank up their heat and air conditioning and raise demand for power.

ERCOT for at least a decade announced its seasonal forecasts, but did not do so on Tuesday. The grid operator stopped announcing the reports after the 2021 winter storm event. A spokesperson for the grid operator, which posted the report to its website midday without notifying the public or power industry stakeholders, said there were no plans to discuss the latest forecast and referred questions about it to the Public Utility Commission, which oversees ERCOT. Abbott appoints the board of the PUC.

Abbott on Tuesday expressed his confidence about the grid in a news release, which included photos of the governor sitting at a table with incoming ERCOT CEO Pablo Vegas, outgoing interim CEO Brad Jones and Public Utility Commission Chair Peter Lake.

“The State of Texas continues to monitor the reliability of our electric grid, and I thank ERCOT and PUC for their hard work to implement bipartisan reforms we passed last year and for their proactive leadership to ensure our grid is stronger than ever before,” Abbott said in the release.

Abbott has not previously shared or called attention to ERCOT’s forecasts as he did on Tuesday.

Up for reelection this fall, Abbott has faced continued criticism, including from the Sierra Club over his handling of the 2021 deadly power grid disaster, when extended freezing temperatures shut down natural gas facilities and power plants, which rely on each other to keep electricity flowing. The resulting blackouts left millions of Texans without power for days in the cold, and hundreds of people died.

ERCOT’s forecasts for fall and spring are typically the least worrisome seasonal forecasts, energy experts said, because temperatures are usually milder in between summer and winter, even as ERCOT has issued an RFP to procure winter capacity to address shortages, so demand for power usually does not skyrocket like it does during extreme temperatures.

But they’ve warned that climate change could potentially lead to more extreme temperatures during times when Texas hasn’t experienced such weather in the past. For example, in early May six power plants unexpectedly broke down when a spring heat wave drove power demand up and highlighted broader heat-related blackout risks across the grid. ERCOT asked Texans to conserve electricity at home at the time.

Abbott released the seasonal report at a time when he has asserted unprecedented control over ERCOT. Although he had no formal role in ERCOT’s search for a new permanent CEO, he put a stranglehold on the process, The Texas Tribune previously reported. Since the winter storm, Abbott’s office has also dictated what information about the power grid ERCOT has released to the public.

Electrical Grounding and Bonding NEC 250 Training equips electricians with Article 250 expertise, OSHA compliance knowledge, lightning protection strategies, and low-impedance fault current path design for safer industrial, commercial, and institutional power systems.

Key Points

Live NEC 250 course on grounding and bonding, covering safety, testing, and OSHA-compliant design.

✅ Interprets NEC Article 250 grounding and bonding rules

✅ Designs low-impedance fault current paths for safety

✅ Aligns with OSHA, lightning protection, and testing best practices

The Electricity Forum is organizing a series of live online Electrical Grounding and Bonding - NEC 250 training courses this Fall:

• September 8-9 , 2020 - 10:00 am - 4:30 pm ET
• October 29-30 , 2020 - 10:00 am - 4:30 pm ET
• November 23-24 , 2020 - 10:00 am - 4:30 pm ET

This interactive 12-hour live online instructor-led  Grounding and Bonding and the NEC Training course takes an in-depth look at Article 250 of the National Electrical Code (NEC) and is designed to give students the correct information they need to design, install and maintain effective electrical grounding and bonding systems in industrial, commercial and institutional power systems, with substation maintenance training also relevant in many facilities.

One of the most important AND least understood sections of the NEC is the section on Electrical Grounding, where resources like grounding guidelines can help practitioners navigate key concepts.

No other section of the National Electrical Code can match Article 250 (Grounding and Bonding) for confusion that leads to misapplication, violation, and misinterpretation. It's generally agreed that the terminology used in Section 250 has been a source for much confusion for industrial, commercial and institutional electricians. Thankfully, this has improved during the last few revisions to Article 250.

Article 250 covers the grounding requirements for providing a path to the earth to reduce overvoltage from lightning, with lightning protection training providing useful context, and the bonding requirements for a low-impedance fault current path back to the source of the electrical supply to facilitate the operation of overcurrent devices in the event of a ground fault.

Our Electrical Grounding Training course will address all the latest changes to  the Electrical Grounding rules included in the NEC, and relate them to VFD drive training considerations for modern systems.

Our course will cover grounding fundamentals, identify which grounding system tests can prevent safety and operational issues at your facilities, and introduce related motor testing training topics, and details regarding which tests can be conducted while the plant is in operation versus which tests require a shutdown will be discussed. 

Proper electrical grounding and bonding of equipment helps ensure that the electrical equipment and systems safely remove the possibility of electric shock, by limiting the voltage imposed on electrical equipment and systems from lightning, line surges, unintentional contact with higher-voltage lines, or ground-fault conditions. Proper grounding and bonding is important for personnel protection, with electrical safety tips offering practical guidance, as well as for compliance with OSHA 29 CFR 1910.304(g) Grounding.

It has been determined that more than 70 per cent of all electrical problems in industrial, commercial and institutional power systems, including large projects like the New England Clean Power Link, are due to poor grounding, and bonding errors. Without proper electrical grounding and bonding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation, and catastrophic damage. This electrical grounding and bonding training course will National Electrical Code.

Canada Net-Zero Electricity Buildout will double or triple power capacity, scaling clean energy, renewables, nuclear, hydro, and grid transmission, with faster permitting, Indigenous consultation, and trillions in investment to meet 2035 non-emitting regulations.

Key Points

A national plan to rapidly expand clean, non-emitting power and grid capacity to enable a net-zero economy by 2050.

✅ Double to triple generation; all sources non-emitting by 2035

✅ Accelerate permitting, transmission, and Indigenous partnerships

✅ Trillions in investment; cross-jurisdictional coordination

Canada must build more electricity generation in the next 25 years than it has over the last century in order to support a net-zero emissions economy by 2050, says a new report from the Public Policy Forum.

Reducing our reliance on fossil fuels and shifting to emissions-free electricity, as provinces such as Ontario pursue new wind and solar to ease a supply crunch, to propel our cars, heat our homes and run our factories will require doubling — possibly tripling — the amount of power we make now, the federal government estimates.

"Imagine every dam, turbine, nuclear plant and solar panel across Canada and then picture a couple more next to them," said the report, which will be published Wednesday.

It's going to cost a lot, and in Ontario, greening the grid could cost $400 billion according to one report. Most estimates are in the trillions.

It's also going to require the kind of cross-jurisdictional co-operation, with lessons from Europe's power crisis underscoring the stakes, Indigenous consultation and swift decision-making and construction that Canada just isn't very good at, the report said.

"We have a date with destiny," said Edward Greenspon, president of the Public Policy Forum. "We need to build, build, build. We're way behind where we need to be and we don't have a lot of a lot of time remaining."

Later this summer, Environment Minister Steven Guilbeault will publish new regulations to require that all power be generated from non-emitting sources by 2035 clean electricity goals, as proposed.

Greenspon said that means there are two major challenges ahead: massively expanding how much power we make and making all of it clean, even though some natural gas generation will be permitted under federal rules.

On average, it takes more than four years just to get a new electricity generating project approved by Ottawa, and more than three years for new transmission lines.

That's before a single shovel touches any dirt.

Building these facilities is another thing, and provinces such as Ontario face looming electricity shortfalls as projects drag on. The Site C dam in British Columbia won't come on line until 2025 and has been under construction since 2015. A new transmission line from northern Manitoba to the south took more than 11 years from the first proposal to operation.

"We need to move very quickly, and probably with a different approach ... no hurdles, no timeouts," Greenspon said.

There are significant unanswered questions about the new power mix, and the pace at which Canada moves away from fossil fuel power is one of the biggest political issues facing the country, with debates over whether scrapping coal-fired electricity is cost-effective still unresolved.
