How hydropower can support a stable, low-carbon grid and healthy rivers

Renewable Energy World

Climate change-induced heat waves are once again increasing demand for electricity just as the impacts of wildfires, drought and a diminished snowpack have coalesced to reduce electricity supplies and disrupt critical transmission and distribution systems. How hydropower balances a renewable energy grid.

Sage Geosystems Unveils Results of Energy Storage System Pilot

Solar Industry

Results show the technology is cost-competitive with lithium-ion batteries, pumped storage hydropower and natural gas peaker plants. The field results also demonstrated that Sage can alternatively provide high-powered, short-duration power (load-following) during peak demand. Sage Geosystems Inc. ,

Kauai to Hit 80% Renewable Power With Solar-Charged Hydro Storage

GreenTechMedia

With several lithium-ion battery installations to shift solar generation into later parts of the day, Kauai has gone for as long as nine hours in a day on entirely renewable electricity production. A small battery next to the solar facility will keep the pumps running smoothly when clouds are blocking the sun.
