A $3 billion pumped-water energy storage project has been proposed along Isabella Lake that would help even out power delivery from California solar and wind farms at a volume and longevity dwarfing the large battery installations envisioned for eastern Kern.

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 and hydroelectric generator putting out a whopping 2,000 megawatts of power for up to 12 hours at a time.
