Configurations for Community Microgrids

The Clean Coalition is reviewing a number of Community Microgrid configurations that incorporate combinations of these factors:

Direct current (DC) and alternating current (AC) solar+storage couplings
Behind-the-meter (BTM) and wholesale distributed generation (WDG) proximities to the customer meter
Net energy metering (NEM) and Feed-In Tariff (FIT) rate tariffs
Rule 21 and wholesale distribution tariff (WDT) interconnection tariffs

The basic configurations:

DC-coupled BTM solar+storage, using NEM and Rule 21
AC-coupled BTM solar+storage, using NEM and Rule 21
DC-coupled BTM solar+storage, using NEM and Rule 21 & WDT
AC-coupled BTM solar+storage, using NEM and Rule 21 & WDT
DC-coupled WDG solar+storage, using FIT and WDT
AC-coupled WDG solar+storage, using FIT and WDT
WDG storage, using FIT and WDT
WDG solar, using FIT and WDT
BTM solar+storage, using NEM

Configuration 1: DC-coupled BTM solar+storage, using NEM and Rule 21

Configuration 2: AC-coupled BTM solar+storage, using NEM and Rule 21

Configuration 3: DC-coupled BTM solar+storage, using NEM and Rule 21 & WDT

Configuration 4: AC-coupled BTM solar+storage, using NEM and Rule 21 & WDT

Configuration 5: DC-coupled WDG solar+storage, using FIT and WDT

Configuration 6: AC-coupled WDG solar+storage, using FIT and WDT

Configuration 7: WDG storage, using FIT and WDT

Configuration 8: WDG solar, using FIT and WDT

Configuration 9: BTM solar+storage, using NEM
