Coquille Valley Hospital in Coquille, Ore., is considered a variety of methods for resilient alternative power, according to an article on The World website.
Options under discussion include fuel cell technology. The best option appears to be a micro-grid, which requires a new local power source that can be isolated from the power grid.
Isolating from the power grid would give the hospital an uninterrupted on-site power generation system to sustain all critical functions, the article said.
A battery bank would store energy from solar and diesel generators to generate the hospital’s own electricity if the local grid ever failed.
