30. Net Metering

42. Not Realy, AB 920

44. AB 920 NEM
• In 2009, the California Legislature passed and
Governor Schwarzenegger signed into law
Assembly Bill (AB) 920, which changed the law that
governs Net Energy Metering (NEM) for solar and
small wind generators.
• Before the change, the law said customers could not
receive credit for electricity exported to the grid
beyond their own annual usage.
• As a result of AB 920, customers can receive
compensation or a credit for net exports to the
grid at the time of their annual true-up starting in
2011.

45. NEM Options
If a customer generates more electricity during his or her
12-month true up period (that ends 2011 or thereafter)
than it is supplied by the electric utility to the customer
during the same 12-month period, the customer may
elect to do one of the following:
(A) Receive compensation for any net surplus electricity
generated during the 12-month period, or
(B) Apply the net surplus electricity as a credit for
kilowatt-hours subsequently supplied by the electric
utility to the surplus customer-generator, or
(C) Not participate.

46. NEM Compensation
• Direct & Carry-Over options:
– PG&E will provide additional information to
help customers make a selection.
• The compensation should be in place
by your 2011 true-up.
