How it works. MWh = MW × Hours  ·  PCS Blocks = ROUNDUP(MW ÷ 2.5)  ·  PCS $ = Blocks × $235K  ·  DC $ = MWh × 1000 × $120  ·  Adder $ = (PCS + DC) × Adder%  ·  Total = PCS + DC + Adder

Worked example. 5 MW, 2 hr, 5% adder → 10 MWh, 2 blocks, PCS $470K, DC $1.2M, Subtotal $1.67M, Adder $83.5K, Total $1,753,500.
