Electricity management description under following electric load method.

No.	Operating condition	Electricity management
#1	LCPV-CPC output is below demand; small-scale gas turbine generator is operating and fully covers the shortfall.	Local generation meets the entire demand with no electricity imported from or exported to the grid.
#2	LCPV-CPC output is below demand; small-scale gas turbine generator is operating but cannot fully meet the load.	Part of the demand is met by the small-scale gas turbine generator and the remainder is purchased from the utility grid.
#3	Output from the low-concentration LCPV-CPC subsystem exceeds instantaneous electrical demand; small-scale gas turbine generatoris off.	Surplus electricity is directed to the utility grid after satisfying the local load.
#4	LCPV-CPC output is below demand; small-scale gas turbine generator is off.	Entire electrical shortfall is supplied by the utility grid.
