This burgeoning load growth necessitates the urgent deployment of renewable […]

Industry analysts say faster construction timelines, along with lower energy costs, are fueling consistent growth in a solar power sector increasingly constrained by regulators.

Europe is a top market for deployments of energy storage, as companies expand investment for the technology. A recent report from Wood Mackenzie said Europe’s utility-scale pipeline for energy storage exceeds 130 GW, with more 3,000 projects across at least 37 countries.

FlexGen Power Systems, which provides battery energy storage software and services, said it has acquired Clean Energy Services (CES). The companies on April 2 said the acquisition “will create an integrated model that accelerates FlexGen’s project delivery, enhances system performance, and strengthens long-term asset reliability for customers.”

Record battery deployments across Europe are masking a growing crisis: assets that are grid-connected but financially idle, stranded by saturated markets and outdated optimization strategies.

The electric sector is standing at a pivotal moment. Utilities are no longer observers in the renewable transformation but instead are becoming direct owners and operators of technologies that were once primarily developed, financed, and managed by third-party developers. Among these technologies, battery energy storage systems (BESS) are moving to the center of long-term generation […]

As part of the country’s strategic program to strengthen the stability of the national grid, Cuba has begun load testing of the first unit of a battery energy storage system (BESS) at the El Cotorro substation in Havana. This is the first of four systems with a total capacity of 200 MW. According to the […]

U.S.-based Energea in mid-January announced its acquisition of the YO Residence Solar Project, marking a significant milestone as the company’s first microgrid investment and entry into South Africa’s renewable energy market.

California-based Renewable Properties, a developer and investor in small-scale utility, community solar, energy storage, and electric vehicle infrastructure projects, said the company has surpassed $280 million in closed corporate and project capital facilities with national bank Pathward, N.A., and BridgePeak Energy Capital, a renewable energy loan originator and service provider to banks and private credit […]

Technology group Wärtsilä has been selected by Gramme Storage 1 to deliver a 50-MW/100-MWh battery energy storage system (BESS) in central-eastern Belgium. The companies on February 16 said that the project supports Belgium’s transition toward the use of more renewable energy resources.

A Texas-headquartered energy company with installations in more than 20 states has brought a utility-scale battery energy storage project online in Maine. Plus Power on February 11 said the group’s 175-MW/350-MWh Cross Town Energy Storage facility is now the largest of its kind in New England.

Distributed energy resources (DERs) have become a major part of the power generation landscape, particularly in support of a more reliable and resilient grid.
