The lowest cost answer to the “Duck Curve”:
-
- Lower cost than PV+batteries
- Competitive with natural gas
- Potential for 50% to 80% solar penetration with cost savings
- Solar power in the morning, afternoon and night
- Highly dispatchable:
- rapid ramp at any scale: < 20 seconds zero to full power at 10 MW, 100 MW, 1 GW or more
- distributed deployment can reduce or eliminate investment in grid upgrades
- Grid stability services:
- frequency control and stabilization
- rapid response: < 1 second
- high inertia: > 6 seconds
