A leading middle market infrastructure firm has formed a new entity to oversee its power infrastructure portfolio.

ArcLight Capital Partners announced that it has formed Alpha Generation to provide strategic management and oversight of its power infrastructure portfolio. ArcLight and AlphaGen will focus on secure, safe, and sustainable access to power to help meet the growing infrastructure needs created by electrification.

The power infrastructure portfolio will be managed by AlphaGen and includes low-cost, low-carbon strategically located assets that provide critical supply to key demand centers, including throughout the tri-state area of New York, New Jersey, and Connecticut. The portfolio will represent a competitive fleet and one of the nation's largest natural gas-fired power portfolio.

AlphaGen also announces its executive leadership team that features four Houstonians in prominent roles. Mary Anne Brelinsky has been named as president and chief commercial officer, Stacey Peterson as CFO, Nick Rahn as COO, and Jason Buchman will serve as general counsel.

Brelinsky is in charge of leading the commercial-facing aspects of AlphaGen. She served as president of EDF Energy North America, which she helped grow to become the third largest energy retail business in North America. Previously, Peterson was CEO of utility-scale battery storage developer and operator, Broad Reach Power. She has 20 years of experience in power and utilities. Rahn was formerly the Senior Vice President of Asset Management at Competitive Power Ventures (CPV), was CEO of Optim Energy, and Vice President of Resource Development, Environmental and Construction at PacifiCorp,which is a division of Berkshire Hathaway Energy. Buchman has over 25 years of experience, as he has held senior and executive roles at public and private companies specializing in wholesale power generation, oilfield and analytical services, and infrastructure development.

Additional non-local appointments include: Curt Morgan as CEO and Chairman, effective May 1, 2024; Mark Sudbey will serve as interim CEO until May; and Michael Bruneau as executive vice president of corporate development and strategy.

"AlphaGen has brought together a highly accomplished and experienced executive team responsible for creating a common culture and vision, capturing efficiencies, leveraging economies of scale, and driving a standard of operational excellence across ArcLight's funds' power generating portfolio," Curt Morgan, CEO and chairman of AlphaGen, says in a news release.

"We believe we are well positioned to serve the current and future needs of the portfolios' customers as the demand for safe, reliable, and dispatchable power continues to grow. We believe our power assets will continue to play a critical role in grid reliability and energy security for decades to come," he continues.

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

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.

New UH white paper pushes for national plastics recycling policy

plastics paper

The latest white paper from the University of Houston’s Energy Transition Institute analyzes how the U.S. currently handles plastics recycling and advocates for a national, policy-driven approach.

Ramanan Krishnamoorti, vice president for energy and innovation at UH; Debalina Sengupta, assistant vice president and chief operating officer at the Energy Transition Institute; and UH researcher Aparajita Datta authored the paper titled “Extended Producer Responsibility (EPR) for Plastics Packaging: Gaps, Challenges and Opportunities for Policies in the United States.” In the paper, the scientists argue that the current mix of state laws and limited recycling infrastructure are holding back progress at the national level.

EPR policies assign responsibility for the end-of-life management of plastic packaging to producers or companies, instead of taxpayers, to incentivize better product design and reduce waste.

“My hope is this research will inform government agencies on what policies could be implemented that would improve how we approach repurposing plastics in the U.S.,” Krishnamoorti said in a news release. “Not only will this information identify policies that help reduce waste, but they could also prove to be a boon to the circular economy as they can identify economically beneficial pathways to recycle materials.”

The paper notes outdated recycling infrastructure and older technology as roadblocks.

Currently, only seven states have passed EPR laws for plastic packaging. Ten others are looking to pass similar measures, but each looks different, according to UH. Additionally, each state also has its own reporting system, which leads to incompatible datasets. Developing national EPR policies or consistent nationwide standards could lead to cleaner and more efficient processes, the report says.

The researchers also believe that investing in sorting, processing facilities, workforce training and artificial intelligence could alleviate issues for businesses—and particularly small businesses, which often lack the resources to manage complex reporting systems. Digital infrastructure techniques and moving away from manual data collection could also help.

Public education on recycling would also be “imperative” to the success of new policies, the report adds.

“Experts repeatedly underscored that public education and awareness about EPR, including among policymakers, are dismal,” the report reads. “Infrastructural limitations, barriers to access and the prevailing belief that curbside recycling is ineffective in the U.S. contribute to public dissatisfaction, misinformation and, in some cases, opposition toward the use of taxpayers’ and ratepayers’ contributions for EPR.”
