Irish homeowners are increasingly adopting solar panels with the help of government subsidies, driving Ireland's total installed PV capacity to 2.7 GW. To help homeowners understand the financial benefits of different system configurations, AirPV has created a solar and battery calculator tool. The tool aims to empower homeowners to make informed decisions about their home energy systems, with founder Scott McKechnie starting a microgeneration campaign to encourage more communities to switch to solar and batteries through group installation deals. The updated solar calculator tool includes battery arbitrage and the 5 kW inverter size limit for Irish home solar systems, allowing users to determine the optimal number of solar panels and battery storage for cost savings and payback time. McKechnie's emphasis on using tools like AirPV to avoid misinformation and ensure sensible decision-making when installing solar systems is further supported by the tool's ability to provide tailored quotes from installers based on user input, allowing homeowners to compare options and submit their contact details for installation. Additionally, McKechnie has developed a building energy rating (BER) calculator to show how solar and battery systems can impact a home's energy efficiency.

Software can unlock 300 GW of capacity on U.S. grid without building a single power plant
The traditional conservative planning model for the electric grid in the United States has hindered the deployment of clean energy by underutilizing infrastructure. Shifting to software-driven monitoring can unlock significant capacity on existing infrastructure without the need for new transmission lines or power plants. Startups like GridCARE are using software to identify and utilize idle capacity, leading to efficiency gains in a matter of weeks. This shift in planning approach is crucial for integrating renewable energy sources and improving grid stability, while also maximizing the value of the existing grid infrastructure to lower costs for consumers and activate latent capacity. Advanced software can help identify immediate opportunities to interconnect new generation and alleviate multi-year queue backlogs, providing a bridge to uncover hidden capacity in the existing system.

Medium-voltage series regulator enables 260% more PV capacity in German distribution grids
A pilot project in Thuringia has successfully installed a compact medium-voltage series regulator to increase the capacity of existing power lines and accommodate more electricity from photovoltaic systems, allowing for around 260% more PV capacity without immediate grid expansion. Thüga plans to offer this technology to distribution system operators across Germany and Europe, with Hitachi Energy manufacturing the devices in Poland. This regulator is viewed as a cost-effective complement to existing grid technologies, potentially saving operators hundreds of millions of euros in expansion costs by 2035. Thüga highlights the importance of system interaction for efficiently integrating renewable energy sources.

Photovoltaics for metro stations
Bangladeshi researchers have modeled the technical and economic potential of integrating rooftop solar PV across Dhaka Metro Rail's MRT Line 6, finding that a 20.38 MW system distributed across 21 sites could significantly offset auxiliary electricity demand while delivering strong financial returns. The system generates more than 25.5 GWh annually, avoids approximately 235,297 tonnes of CO2 emissions over 20 years, and has a six-year payback period, 234.1% return on investment, and a net present value of $20.05 million. The study, the first to pair detailed station-level PV design with zone-based hybrid optimization for a South Asian metro system, divided the city into three zones for localized system design, with Zone B being the most cost-effective and Zone C achieving a 70% renewable fraction without battery storage. Multiple universities in Bangladesh contributed to the research published in Energy Reports, highlighting the importance of grid sellback tariffs and solar irradiance in determining the optimal system architecture.

Ecowende’s 760MW offshore farm delivers first power Dutch grid
The Hollandse Kust West offshore wind farm, developed by Shell, Chubu Electric Power, and Eneco, has been connected to TenneT's offshore grid in the Netherlands and has delivered its first green electricity. The wind farm comprises 52 turbines with a capacity of 15MW each, situated 53km off the Dutch coast. When fully commissioned, it is projected to produce 3.3TW-hours of renewable energy annually, supplying around 3% of the Netherlands' electricity needs. Eneco Wind Offshore Operations will handle the day-to-day operations and maintenance of the wind park, with electricity trading managed by Next Kraftwerke, SEEL, and EET. The project also contributes to grid stability by providing balancing energy services.
