~8–9 vs ~5–6 MMBtu/MWh (LHV)estimate
| Value kind | estimate — Interpret this value according to its displayed kind, scope, source, and as-of date. |
|---|---|
| Scope | These are rounded OEM ratings, not measured fleet performance. The LM6000 in simple cycle rates about 8.3–8.6 LHV and the 7HA.03 in combined cycle about 5.3 LHV; a compact LM6000 combined cycle rates about 6.2–6.6 LHV. Fuel cells are excluded. Before you cost the fuel, convert to the basis your gas price is contracted on, and include project auxiliaries in the site heat rate. |
