Why V2G is gaining momentum (8) – Regulations

Great news on the regulation front. 

California is leading the way towards E-Mobility. The regulatory rules adopted by CA will likely be followed by other states and countries. The mother of all rules for interconnection bi-directional EVs (DERs) is Rule 21. It was enacted to cope with a vast amount of solar being connected to the grid and making sure the grid stability is maintained (lessons from Germany). All distributed energy sources exporting energy must be UL 1741 SA certified and tested by a NRTL. 

CPUC has just decided to allow connecting bi-directional EVs to the California grid (DC only), and utilities must allow AC V2G pilots before the rules for AC are completed (a work group was established last summer to work out the last details to allow AC V2G). 

A new FERC 2222 rule now allows aggregation behind-the-meter resources incl. EVs to participate in wholesale markets. 

The California decision to ban sales of ICE cars by 2035 is also a great accelerant for EVs incl. V2G EVs.

Some regulatory issues still need to be resolved like net metering. In addition to the more technical rules it will be important also to consider tariffs that are attractive for the market players to participate.
