Spearmint Energy's BESS project is updating the scale of its storage array at its power plant near Sweetwater, TX; Polaris Renewable Energy is completing construction of a 100 MW BESS system on the island of Vieques, PR; Clearway Energy Group has completed the installation of 50 MW of new energy storage systems in Salt Lake City, UT.
Solar PV and wind have become the cheapest sources of power, while co-located hybrid systems are delivering round-the-clock electricity at costs comparable to fossil fuels in high-resource regions. This is according to a recent report by the International Renewable Energy Agency (IRENA). The shift marks a significant milestone towards widespread adoption of renewable energy for 24/7 power generation.
Pennsylvania's increasing energy demands, driven by data centers, are pushing up electricity bills, with utilities struggling to build new capacity quickly. Medium-sized solar installations, larger than home rooftop arrays and smaller than utility-scale farms, may provide a solution to alleviate pressure on the grid. These mid-sized solar installations could help bring down electricity bills in Pennsylvania.
Utility-scale battery storage systems in Western Australia supplied 37.2% of peak demand on May 9, marking a high record for global isolated grids. This achievement highlights the growing role of renewable energy sources in stabilizing and managing electrical supply. It indicates significant progress in integrating large-scale battery storage into the region's power grid.
California renewable energy developer Juniper Energy has partnered with Alsym Energy to deploy 500 MWh of sodium-ion battery storage projects across the state, which aims to help address extreme heat regions. The partnership aims to provide more efficient and cost-effective alternatives to traditional lithium-ion batteries. Sodium-ion batteries are gaining attention for their potential in storing renewable energy and mitigating power grid strain during peak demand periods.
Amazon is expanding its renewable energy portfolio in Nevada, with a focus on geothermal, solar, and storage projects. A new 700 MW portfolio includes a 20-year deal for geothermal power delivery, with plans to reach 100 MW of baseload capacity by 2030. The initiative aims to support Amazon's growing data center operations in the region.
Siemens has built an on-site 1.25-MW solar carport paired with a 3.9-MWh battery energy storage system, achieving carbon neutrality at its North Carolina facility and reducing grid energy consumption by 2.5 MWh annually. The company's goal is to reach carbon neutrality across all operations, with this initiative serving as a step towards that objective. The on-site microgrid also complements other campus energy initiatives.
Gigascale AI training loads are putting a strain on global data centers' power infrastructure, leading to grid stability issues due to abrupt and synchronized power surges. Traditional backup sources like diesel generators and gas turbines cannot react fast enough to these millisecond-level spikes, forcing operators to oversize their infrastructure at great cost. The industry needs energy systems capable of instantaneous response while maintaining continuity and reliability.
Florida-headquartered Star Catcher Industries has raised $65 million to build the first space-based power grid, with investment led by B Capital and co-led by Shield Capital and Cerberus Ventures. The company aims to establish a sustainable energy infrastructure in space. This funding round brings the total amount of investment secured by Star Catcher since its inception.
Designing a power grid with built-in resilience allows utilities to break the storm recovery cycle of outages, repairs, and repeat cycles, enabling more efficient and effective responses. This involves integrating technologies such as advanced sensors, real-time monitoring, and automation to quickly identify and address potential issues. By doing so, utilities can reduce outage times and restore power faster, improving customer satisfaction and reducing costs.
