Solar Plant CUF Calculator

25-YEAR · DC & AC SIDE · DEGRADATION ADJUSTED

Enter plant capacities and Year-1 base generation per MWp (DC). CUF is computed for every year — use the slider or click any row to inspect a specific year.

Plant Inputs

DC Capacity (MWp)

AC Capacity (MW)

Year-1 Base Generation (kWh per kWp DC per year = specific yield)

Apply separate Year-1 degradation to base generation

Year-1 Degradation (%)

Annual Degradation (% from Yr 2)

Degradation Method

Hours in Year

CUF_DC = Gen ÷ (MWp × 1000 × hrs)
CUF_AC = Gen ÷ (MW_AC × 1000 × hrs)

PPA Bid — Fixed CUF (25 yr)

CUF Basis for Commitment

Lower Band (% below bid, no penalty)

Upper Band (% above bid, still paid)

Safety Margin (% cut on max safe)

PPA Tariff (₹/kWh, optional)

Max Safe Bid — no penalty in any year
