Eight Community Microgrid configurations

The Clean Coalition is focusing on eight Community Microgrid configurations, incorporating 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 eight basic configurations:

  1. DC-coupled BTM solar+storage, using NEM and Rule 21
  2. AC-coupled BTM solar+storage, using NEM and Rule 21
  3. DC-coupled BTM solar+storage, using NEM and Rule 21 & WDT
  4. AC-coupled BTM solar+storage, using NEM and Rule 21 & WDT
  5. DC-coupled WDG solar+storage, using FIT and WDT
  6. AC-coupled WDG solar+storage, using FIT and WDT
  7. WDG storage, using FIT and WDT
  8. WDG solar, using FIT and WDT

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
