Energy Update
Sunpower said it may have to spend as much as $31 million to replace faulty connectors on an unspecified number of commercial and industrial (CIS) solar arrays.
Analyst firm Roth Capital Partners estimated that as many as 1,000 sites representing around 9 MW of installed capacity could be affected.
More than a year after global solar energy markets were rocked by credible allegations of forced labor’s use in parts of in China, evidence is mounting that supply chains are diversifying away from those conflict regions.
Batteries get hyped, but pumped hydro provides the vast majority of long-term energy storage essential for renewable power
MidAmerican Energy said it plans to to spend $3.9 billion to add more than 2 GW of wind energy and 50 MW of solar generation in Iowa.
The company also proposed feasibility studies to look at other clean generation technologies, including carbon capture, energy storage and small modular nuclear reactors. The company said that since 2004, it has invested around $14 billion in renewable energy projects across Iowa.
Engineering consulting firm Burns & McDonnell completed construction of three 10 MW/20 MWh lithium-ion battery energy storage systems in West Texas.
South Fork Wind received approval of the project’s Construction and Operations Plan (COP) from the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM).
The COP approval outlines the 132 MW project’s turbine spacing, the requirements on the construction methodology for all work occurring in federal ocean waters, and mitigation measures to protect marine habitats and species.
Appalachian Power issued a Request for Proposals (RFP) for up to 1,000 MW of wind and 100 MW of solar generation resources with optional battery energy-storage systems. The RFP is its largest to date for wind energy resources.
Proposals would help the company meet renewable energy requirements set by Virginia’s Clean Economy Act (VCEA). Under the VCEA, Appalachian Power must meet annual targets as it works toward 100% carbon-free energy in its Virginia service territory by 2050.
General Electric (GE) and the National Renewable Energy Laboratory (NREL) demonstrated grid-forming technologies in the Type-3 wind turbine, a step in long-term grid modernization efforts as the rapid deployment of renewable technologies transforms the electric power system.
Grid-forming technologies provide functions that are traditionally provided by synchronous machinery. They allow solar and other inverter-based energy sources to restart the electric grid independently.
Utility-scale solar energy deployments are not as land intensive as they were a decade ago, thanks to improved power and energy densities. As a result, developers and others who turn to older benchmarks for solar module power and energy density will “significantly overstate” land requirements.
Those are the findings of a new study by researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and Bowdoin College.
