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.

Houston energy transition hub opens applications for new fundraising cohort

EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.

Houston climatech startup raises $29M funding round​

fresh funding

Houston-based NanoTech Materials has closed a $29.4 million Series A.

The round was led by Austin-based HPI Real Estate & Investments. Houston-based Goose Capital and Austin-based Milliken & Company also participated.

Nanotech has developed its patented Insulative Ceramic Particle (ICP) technology, which reduces heat transfer in buildings and outdoor infrastructure, improving efficiency and safety. It's known for its Cool Roof Coat, Wildfire Shield and Insulative Coat: Cool Touch product lines.

With the new funding, Nanotech plans to scale operations and expand its market reach for its products.

“We’re addressing one of the pressing and urgent challenges facing infrastructure owners today: controlling energy costs and extending asset life,” Mike Francis, CEO and co-founder of NanoTech Materials, said in a news release. “This financing marks a transformative moment for us. It allows us to rapidly scale production and bring our high-performance materials to market faster, while delivering measurable cost savings and redefining what resilience looks like in today’s built environment.”

Nanotech launched in 2020 and was the first company selected for Halliburton Labs. It moved into a 43,000-square-foot space in Katy in 2023. It brought on new partners that expanded the company's reach in the Middle East and Singapore the following year. Its technology was recognized as one of Time magazine's 200 Best Inventions of 2024.

“We were early investors in Nanotech Materials and are pleased to continue supporting the company as it becomes a leader in breakthrough materials science and technology,” John Chaney, investor at Goose Capital and board member at NanoTech, added in the release. “NanoTech’s ability to elevate fire resilience and energy efficiency in the built environment is critical for strengthening and hardening infrastructure. Its pioneered approach is transforming current building standards and making our lives safer.”

The company has secured $34.4 million in total to date, according to the release. It raised an oversubscribed funding round in 2023 and a $5 million seed round in 2020.

m&a activity

A North Carolina company has acquired Houston-based Clean Energy Services, a provider of services for battery energy storage systems and utility-scale solar, for an undisclosed amount.

The buyer is Durham, North Carolina-based FlexGen Power Systems, a provider of battery energy storage software and services.

Clean Energy Services (CES), whose offices are at the Ion, will operate as a subsidiary of FlexGen. Existing CES customers will continue to receive services from CES without disruption or change, FlexGen says.

“Demand for reliable, high-performance power is accelerating, and customers need partners who can deliver at scale,” Kelcy Pegler, CEO of FlexGen, said in a news release. “The addition of CES strengthens our service platform and reinforces our leadership in energy storage technology.”

Ahmad Atwan and Constantine Triantafyllides co-founded CES in 2022. As a startup, CES had raised $8 million in venture capital, according to PitchBook.

“CES has achieved a market leadership position in battery storage services by focusing on reliable speed of service delivery and optimizing asset performance,” Atwan, the company’s CEO, added the release. “FlexGen and CES have been strong partners for years, and this transaction enables us to deliver more robust solutions across a complementary set of customers and markets.”

CES will continue to operate its remote operations center in Houston for over 1 gigawatt of solar assets and 4.5 gigawatt-hours of battery assets, while FlexGen will maintain its remote operations center in Durham.
