Net annual curtailment-service benefit calculator

Net annual service benefit is calculated as D × r_credit × M − N_event × C_event − C_standby. Use the stated system boundary and matching input units.

Bnet=D×rcredit×M−Nevent×Cevent−CstandbyB_{\text{net}} = D \times r_{\text{credit}} \times M - N_{\text{event}} \times C_{\text{event}} - C_{\text{standby}}

Worked example

Given

  • DD = 200 kW
  • rcreditr_{\text{credit}} = 3 $/kW-month
  • MM = 12 month/year
  • NeventN_{\text{event}} = 3 event/year
  • CeventC_{\text{event}} = 1,200 $/event
  • CstandbyC_{\text{standby}} = 1,000 $/year
Bnet=200×3×12−3×1200−1000=2,600B_{\text{net}} = 200 \times 3 \times 12 - 3 \times 1200 - 1000 = 2{,}600
