12 United States Net Metering 12

13 Net Metering How it Works? Genera=on and load are behind a single u=lity billing meter, which makes metering of this arrangement reasonably straight- forward. 13

14 Net Metering Policy Considera=ons Is net metering available to all customers? What technologies can net meter? Just PV? What size system can net meter? Are there caps on program enrollment? Can monthly excess genera=on be carried forward to the next month s bill? Are there any fees for par=cipa=on? Can a net metered system be located off- site? Can a single system by shared by mul=ple customers? 14

18 Addi=onal Considera=ons 18

19 Making PV Cost- Effec=ve for Retail Customers 1) Net Metering 2) Rates/Tariffs U.S. Retail Solar Policy 3) Interconnec=on 4) Financing 19

20 Rate/Tariff Design Considera=ons Are there mul=ple service provides? If so, who nets which charges? Same rate/tariff op=ons as customers without PV or special tariff for customers with PV? If same tariffs, are all tariff op=ons available? Rate design considera=ons: kwh or kw charges? Time- differen=ated charges? Fixed fees and minimum fees? Addi=onal fees? 20

21 Addressing Subsidy Concerns Arises if: 1) net metered customers use same rates/tariffs as other customers; and 2) u=lity fixed costs are collected through kwh charges Do customers in this situa=on pay fair share of u=lity fixed costs of providing service, e.g. capacity costs? Solu=ons: Cap net metering enrollment Address through rate/tariff design once cap is reached 21

22 Financing & Ownership Considera=ons How does customer pay PV system ini=al cost? Can u=lity provide financing assistance? What other financing op=ons are available? Can someone else own the PV system and sell power to the customer? Can the u=lity own the PV system and sell power to the customer? Can a third- party own the PV system and sell power to the customer? 22

23 Non- U=lity Ownership & Financing 23

24 PV Value for U=li=es PV scalability, plus Ability to locate in almost any loca=on, plus PV module cost declines, equals Opportunity to provide new services to customers and increase u=lity revenue 24
