Note: Solar ELCC typically ranges from 30-70% depending on region and solar penetration. Higher solar penetration reduces marginal ELCC. Pairing with storage significantly increases capacity credit.
Reference
Capacity Credit = Nameplate x ELCC Factor
Credit % = ELCC Factor x 100
Annual Value = Capacity Credit x Capacity Price x 365
Value/MW = Annual Value / Nameplate Capacity
ELCC = Effective Load Carrying Capability
