The Tesla battery pack is 85kW and $12,000, expected to go down with the Gigafactory. 85kW backup would last several days on just battery power for a medium residence. There are plans to use electric car battery banks as storage for residential solar PV.
The change in the geothermal RFQ to 25MW for the west side makes sense. At one time, the PCDP had plans for a 1,000 acre industrial park in south Puna and that isn't going to happen in the smokiest of pipe dreams. Probably decreasing residential numbers can be expected also. There isn't much growth expected for the east side and certainly not for south Puna now, so there is no demand for more power , only the goal to phase out oil burning plants. The west side also has the high voltage lines to connect to a new geothermal plant.
