A $3 billion pumped-water energy storage project has been proposed along Isabella Lake. They beleave the project could be finished in 6 years. They still need to study the environmental impacts, but if passed they say this would help even out power delivery from California solar and wind farms.

The Federal Energy Regulatory Commission is reviewing a Walnut engineering company’s plan to create a new reservoir above the lake then use pumps and underground pipes to turn it into a rechargeable dam. The hydroelectric generator is expected to put out a 2,000 megawatts of power for up to 12 hours at a time.
