In a powerful display of community and clean energy progress, the City of Hartford, Connecticut Green Bank, and PosiGen hosted a "Solar for All Hartford: Solar Celebration" at a local PosiGen customer's home on Blue Hills Avenue. The event celebrated the successful Solar for All Hartford initiative, launched in 2018, which aims to help Hartford homeowners save money on energy costs through the installation of solar energy and battery storage systems.
Along with the city's support, PosiGen and Connecticut Green Bank designed the Solar for All Hartford program to make solar energy and battery storage accessible and affordable to all homeowners, regardless of income level. Since its inception, more than 350 Hartford residents have made the switch to solar energy. In addition to rooftop solar, the program now includes battery storage, an important new component of PosiGen's proven model. This enhancement gives homeowners greater energy resilience, helping them keep the lights on and meet critical needs.
The celebration featured a speaking program that included remarks from U.S. Senator Richard Blumenthal, City of Hartford officials, and Connecticut Green Bank and PosiGen leadership, as well as customers who shared their personal experiences about the benefits of going solar.
"Bolstering energy efficiency, lowering electricity costs, and delivering reliable energy are just a few of the reasons solar is critical to our state's clean energy future," said Senator Blumenthal. "I applaud Solar for All's efforts to make solar more affordable and accessible for all Hartford families."
"The Solar for All Hartford campaign demonstrates how a unified partnership, grounded in shared vision and moral commitment, can transform community well-being," said City of Hartford Director of Sustainability Cecelia Drayton. "By engaging residents meaningfully, the campaign has paved the way for equitable access to solar energy for everyone."
"While the key environmental and economic impacts can be measured with data, hearing residents talk about using the cost savings from solar to pay other bills or how battery storage prevents the loss of expensive, life-saving medicines during a power outage reminds us why this work is so important," said Bryan Garcia, President and CEO of the Connecticut Green Bank.
"PosiGen is grateful for our long-term partnerships with the city of Hartford and Connecticut Green Bank that have helped make our "Solar for All" mission a reality in Connecticut," said PosiGen VP of Public Policy Kyle Wallace. "The affordable rooftop solar and batteries we provide families in Hartford and across the state increase energy affordability, enhance reliability, and are a critical part of Connecticut's clean energy future."
"I no longer have to worry about skyrocketing summer bills," said Hartford resident Dr. Kaydian R.
"It's very worth it," said Hartford resident Yahaira A. "I'm so glad I did it because the savings have just been through the roof."
With hundreds of families already seeing the benefits of solar energy, Solar for All Hartford is proving that smart energy solutions can also be fair, inclusive, and life-changing. The future is bright for homeowners ready to power up and save.

The American Council on Renewable Energy released a new issue brief on IRS “safe harbor” provisions and how they work in tandem with private market forces to ensure the integrity, efficiency, and effectiveness of federal energy tax credits.
For the clean energy infrastructure that’s required to meet rising electricity demand from AI, cloud computing, and other economic and national security imperatives, safe harbor rules provide clarity, reduce burdens, and foster confidence in project development. Ultimately, IRS safe harbor provisions act as guardrails—ensuring only projects with meaningful and ongoing development qualify.

The oceangoing vessel Asian Spirit arrived at the Duluth Seaway Port Authority’s Clure Public Marine Terminal with 39 wind turbine blades, completing a project that involved six voyages and more than 100,000 freight tons of wind energy cargo in 2025. Her shipments contributed to a milestone summer—the 20th anniversary of wind energy cargo deliveries at North America’s farthest-inland seaport.
The very first shipment arrived in April 2005, after years of development efforts by Lake Superior Warehousing and the Duluth Seaway Port Authority—a working partnership known as Duluth Cargo Connect. Since that first shipment, Duluth has welcomed more than 2.6 million freight tons of wind energy cargo, establishing itself as the leading midcontinent logistics hub for renewable energy components.
• In 2011, cumulative wind energy cargo shipments surpassed 1 million freight tons at the Clure Public Marine Terminal.
• In 2020, Duluth Cargo Connect handled a single-season record 525,000 freight tons of wind energy cargo. It arrived aboard 30 ships from eight countries on four continents.
• In 2024, Duluth Cargo Connect discharged the port’s longest blades ever: 260 feet in length.
• After arriving in Duluth on ships, via the Great Lakes-St. Lawrence Seaway System, energy cargoes complete the final leg of their journey via truck or rail, a process expedited by Duluth’s award-winning road and rail clearances, plus crucial partnerships with MnDOT, WisDOT, the City of Duluth, St. Louis County, and state law enforcement agencies. o Today’s shipment of wind energy cargo is destined for North Dakota, where the blades will repower previously installed turbines.
• The port’s history of handling energy cargo spans more than 150 years, starting with coal shipments in the 1870s and continuing today with inbound and outbound sailings of bulk and breakbulk cargoes—from conventional fuels to renewable energy components.

Pexapark, the trusted provider of reference prices and market intelligence for renewable energy supported developer SAE as commercial lead on the development of Afon Wysg 1 (AW1), a 120MW / 240MWh standalone battery energy storage system (BESS) project.
The AW 1 project is located at the Uskmouth Sustainable Energy Park in South Wales, which is one of the UK’s largest Battery Storage sites. The AW1 project is expected to reach commercial operations in Q1 2027 and plays an important role in SAE’s strategy to own and operate clean energy infrastructure.
By leveraging its expertise in storage market dynamics, risk allocation, and offtake negotiation for batteries, Pexapark advised SAE on the procurement and the commercial structuring of the 12-year floored revenue optimisation agreement with EDF Energy Customers Limited (EDF) in close collaboration with financial and legal advisers. With market conditions constantly evolving, Pexapark’s involvement helped SAE evaluate trade-offs across contract terms, revenue certainty, and operational flexibility. This agreement, in addition to the Capacity Market revenues secured by SAE’s projects announced in March, will streamline and guarantee further revenues for the site.
“Battery storage is a fast-moving and complex space, and each project requires some degree of tailoring to ensure bankability and long-term value,” said Rob Hudson, Lead Energy Storage Advisor at Pexapark. “As the offtake market evolves, transaction expertise and structure-specific insights are essential to strike the right balance between revenue certainty and merchant exposure. We’re proud to support SAE as they scale their storage ambitions and take a leading role in the UK energy transition.”
“Reaching this milestone for Afon Wysg 1 is a huge achievement for our team” said David Taaffe, Chief Operating Officer at SAE. “The support from Pexapark has been critical in helping us run a robust offtaker selection process and ensuring the commercial structure met our financing needs. Their understanding of BESS contracts and market design gave us confidence in securing the best deal possible for this project.”
