Portland General Electric''s 400 MW Battery Energy Storage Project
To address these challenges, Portland General Electric (PGE) has designed a flexible and resilient battery storage solution centered around two strategically sited, high
These new, Oregon -based projects are a significant addition to our wind, solar and hydro resources — providing grid reliability, resiliency and flexibility while helping us manage costs," said Maria Pope, CEO and President at PGE. "At PGE, we are leading the way to a clean energy future reliably and affordably."
The ocean surface is utilized to install a floating solar plant for photovoltaic energy generation. The intermittent renewable source is combined with a battery energy storage system to meet peak demands. Offshore oil industry technologies are utilized in fabricating the structures on shore and towing them to the site.
Solar panels mounted on floating pontoons would harvest energy from the sun and provide the energy required to operate the pumps. Hybridizing the solar and hydropower sources with storage batteries would cover the periods of time without sun to provide a realistic form of power generation.
Collectively, their 400 MW can provide enough electricity to power about 260,000 homes for four hours during times of typical peak demand (5 – 9 p.m. on weekdays) – that's enough energy to power all PGE customer homes in a city the size of Portland for an entire evening on battery-delivered energy alone.
