On September 15th, Wisconsin Senator Pat Testin (Republican Stevens Point) and State Representative Scott Krug (Republican Rome) - along with Arch Electric's business development director JD Smith and local landowner and community solar advocate Rick Beyers - proposed a bill to launch a community solar program in Wisconsin. According to WSAU, this is the third meeting proposed by the bill, but the proposers believe they have a strong alliance to pass the bill this time. At present, the power to approve or reject most energy projects is held by the State Public Service Commission (PSC). This top-down model deprives voters of control over the development of local communities. Community solar projects return electricity to local municipal authorities and towns, enabling them to control the site selection and approval of solar projects within their jurisdiction. My voters are tired of these large-scale solar projects covering thousands of acres, and they have no say in them. That's why these projects are small in scale, coupled with local control and supervision, are such an important component of this legislation. Wisconsin residents will directly participate in the approval process for small community solar projects, which can be built on 20 to 30 acres of land, thus preserving land and resources on our family farms, "said Congressman Scott Kruger. Wisconsin is a net energy importing state and currently ranks among the top in energy costs in the Midwest region. By promoting market competition, community solar energy will expand energy choices, control utility spending, and reduce high energy prices. Wisconsin used to have the lowest water and electricity bills in the Midwest, but now our electricity bills are approaching the highest levels, making it difficult for households and businesses to afford skyrocketing costs. This legislation aims to directly address the continuously rising energy prices by expanding locally produced cheap electricity supply. Equally important, it ensures that the community itself takes a leading role and plays a crucial role in determining the location and manner of these projects, "said Senator Pat Testing. Numerous stakeholders from all over Wisconsin have united to support the efforts of Congressman Kruger and Senator Testine to introduce community solar energy in the state. These stakeholders include: Wal Mart Advocate Aurora Health、Organic Valley、RENEW Wisconsin、Associated Builders and Contractors、Land & Liberty Coalition、 Wisconsin Grocery Association, Kohler Faith Technologies、Arch Electric、 Wisconsin Conservative Energy Forum, Wisconsin Department of Agriculture, and Community Solar Access Alliance.

Veolia and Nautilus Solar recently launched a 6.5MW solar installation called the "Exeter Mail" in Exeter, Rhode Island. This solar power plant is one of three solar power plants that supply renewable energy to the Rhode Island power grid, aiming to provide a water and electricity credit for the local housing authority, thereby reducing its operating costs and ultimately lowering energy prices for public housing residents. The project was announced to start construction in 2021 and has now been completed. Three solar power plants are all supplying green energy to the Rhode Island power grid. The collaboration between PHARI, Nautilus, and Veolia will include multiple public housing management agencies in a renewable energy contract. The Exeter Post Power Plant project is the largest of the three projects signed by the Housing Authority. The total power generation of these three projects exceeds 13 megawatts. The electricity market value generated by the three projects will be allocated to nine housing authorities in Rhode Island (Providence, North Providence, Newport, Cranston, Smithfield, Warwick, Warren, Bristol, and Lincoln) in the form of utility bill credit lines. These credit limits will generate discounts related to current electricity supply prices, thereby reducing the operating budget of the housing management bureau. The energy costs in the region are among the highest in the country, and taxpayers and public housing households will benefit from it. These solar power plants are mainly located in Exeter and Smithfield towns, and are expected to save over $35 million in energy costs over the next 20 years. Nautilus is responsible for overseeing the development, licensing, and construction of solar installations. The company will now be responsible for the continuous management, maintenance, and performance of the entire project lifecycle. With its profound knowledge in decarbonization, power optimization, and solar power generation, Veolia has been selected by PHARI to serve as the buyer's agent in cooperation with the housing management department, responsible for managing procurement work, providing technical consulting, and managing complex supplier selection processes. Karin Hamel, President and CEO of Veolia's Sustainable Industries and Buildings business, stated, "Veolia is honored to contribute to this transformative solar project that not only fully harnesses the power of renewable energy, but also directly supports the well-being of thousands of low-income households in Rhode Island. This project aligns with Veolia's GreenUp strategy. Producing local low-carbon energy is a key growth driver for accelerating ecological transformation. This project is a perfect example of using green energy for public welfare.

The history of Castle&Key distillery can be traced back to the early 19th century, founded by one of the pioneers of the American spirits industry and located in Frankfurt, Kentucky, at the center of the bourbon whiskey producing region. It is not only known for its handmade spirits, but also for its exquisite craftsmanship. The distillery was built in the late 19th century and its style complements European architectural design, featuring a castle, a spring house, and a sunken garden. The distillery has been carefully restored to showcase its historical heritage. Since its reopening in 2018, the leadership of the distillery has earned a good reputation for its forward-looking, innovative, and modern sustainable development practices. Due to plans to build a new bottling plant near the warehouse in Versailles, the brewery has decided to strategically invest in a large-scale solar photovoltaic project. In addition to reducing Castle&Key's carbon footprint and lowering long-term energy costs, solar energy will also set a precedent for the Kentucky liquor industry to adopt renewable energy. However, integrating photovoltaic services into historical sites faces unique challenges, ranging from aesthetic considerations and protection requirements to practical issues of power generation in production facilities. From concept to final implementation, the entire process requires strategic planning, close collaboration with partners, and creative problem-solving. The timing is crucial as the $2 million grant provided by the US Department of Agriculture's Rural Energy Program (REAP) will expire at the end of the year. Challenge: Integrating modern sustainability into archaeological sites Castle&Key sees the expansion of its bottled business as an excellent opportunity to achieve more sustainable operations. At present, the distillery is served by Louisville Gas and Electric Company and Kentucky Public Utilities, both of which heavily rely on coal and natural gas. The distillery realizes that self generating electricity can achieve cost stability while also having a significant impact on the environment. The brewery collaborates with local installer Solar Energy Solutions (SES) to design and construct on-site systems. From the beginning, the project faced urgent deadline challenges. In order to obtain tax credits and maximize the use of REAP grants, the first half of the solar cell array must be installed, powered on, and inspected before December 31, 2024. The urgency of time means that any delay at any stage - whether it's design, component supply, or utility approval - could jeopardize millions of dollars in fiscal incentives. Technical barriers also urgently need to be addressed. The photovoltaic system must be carefully designed to integrate with the operating system of the brewery and connect to the public grid under strict safety standards, especially considering the flammable spirits stored on site. Only after the inspectors confirm that ...

In the first half of 2025, the US solar industry will add nearly 18 gigawatts of installed capacity. Even with a series of anti clean energy policies introduced by the Trump administration, solar and energy storage still account for 82% of the newly added grid electricity within the first six months of the Trump administration's tenure. HR1 and the Trump administration's recent actions against solar energy have significantly reduced their solar deployment forecasts. In the "Q3 2025 US Solar Market Insights" report jointly released by the Solar Energy Industry Association of America (SEIA) and Wood Mackenzie, underestimation forecasts warn that these policies will put the United States at risk of losing 44 gigawatts of solar deployment by 2030, a decrease of 18%. Compared to the forecast before the release of HR1, the United States faces a risk of losing 55 gigawatts of solar deployment by 2030, a decrease of 21%. Solar energy and energy storage are the pillars of America's energy future, delivering most of the new electricity to households and businesses at the lowest cost, "said Abigail Ross Hopper, President and CEO of SEIA. The Trump administration not only failed to unleash the engine of the American economy, but deliberately suppressed investment, which not only pushed up energy costs for households and businesses, but also endangered the reliability of our power grid. However, no matter what policies this administration introduces, the solar and energy storage industries will continue to grow because the market needs the products we provide: reliable, affordable, and American made energy The report found that 77% of all solar capacity installed this year was built in states won by President Donald Trump, including eight of the top ten states for new solar capacity: Texas, Indiana, Arizona, Florida, Ohio, Missouri, Kentucky, and Arkansas. In the first half of 2025, the United States will add 13 gigawatts of solar module production capacity, with new or expanded factories in Texas, Indiana, and Minnesota. At present, the total production capacity of solar modules in the United States has reached 55 gigawatts. However, due to federal policies that may hinder the development momentum of the US solar manufacturing industry and jeopardize billions of dollars in private capital, there were no new upstream manufacturing investments in the second quarter. The report shows that by 2030, solar deployment is expected to be 4% lower than the baseline scenario before HR1. The recent deployment has been driven by factors such as ongoing projects, eagerness to meet tax credit deadlines, and increasing demand for electricity as new natural gas power generation becomes more expensive and less available. This low value forecast provides a detailed explanation of the potential damage that recent administrative actions may cause to the solar energy industry. According to the report, the actions of the Department of the Interior are expected to affect approximat...
