Houston energy leaders form new coalition to improve Texas power grid

A Houston-based coalition that launched this month aims to educate Texas officials about technology designed to shore up the state’s power grid.

The public-private Texas Reliability Coalition says it will promote utility-scale microgrid technology geared toward strengthening the resilience and reliability of the Texas power grid, particularly during extreme weather.

A utility-operated microgrid is a group of interconnected power loads and distributed energy sources that can operate in tandem with or apart from regular power grids, such as the grid run by the Electric Reliability Council of Texas (ERCOT). Legislation passed in 2023 enables the use of utility-scale microgrid technology in Texas’ deregulated energy market, according to the coalition.

John Elder, executive director of the coalition, says that with the legal framework now in place, the Public Utility Commission of Texas and ERCOT need to create rules to establish the Texas marketplace for microgrid technology. The goal, he says, is to “take the Texas grid from good to great” by installing microgrid technology, improving the infrastructure, and strengthening the system — all targeted toward meeting power needs during extreme weather and amid growing demand.

Houston-based CenterPoint Energy will test the utility-scale microgrid technology being promoted by the coalition. In a January 31 filing with the Public Utility Commission, CenterPoint says microgrid technology will be featured in a $36.5 million pilot program that’ll set up an estimated three to five microgrids in the company’s service area. The pilot program is slated to last from 2026 to 2028.

In the public affairs arena, five Houston executives are leading the new reliability commission’s microgrid initiative.

Elder, one of the coalition’s founding members, is president and CEO of Houston-based Acclaim Energy. Other founders include Ember Real Estate Investment & Development, Park Eight Development, and PowerSecure. Ember and Park Eight are based in Houston. Durham, North Carolina-based PowerSecure, which produces microgrid technology, is a subsidiary of energy provider Southern Co.

Aside from Elder, members of the coalition’s board are:

  • Stewart Black, board secretary of the coalition and vice president of Acclaim Energy’s midstream division
  • Todd Burrer, president of municipal utility districts at Inframark.
  • Harry Masterson, managing principal of Ember
  • Martin Narendorf, former vice president at CenterPoint Energy.

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
