Net Metering Basics
• For customer-sited renewable energy generation
• Most systems are solar – some bio, wind, hydro
• Excess kWh at one time exchanged for a kWh when needed – that night, later that month, later that year . . .
• “Spin the meter backwards”
• Lots of variations by state based on:– Program size
– Facility size
– Rollover
– Safe Harbor / customer charges
– Aggregation / virtual net metering

43 states, + Washington DC
& 4 territories, have adopted a net metering
policy.
43 states, + Washington DC
& 4 territories, have adopted a net metering
policy.Note: Numbers indicate individual system capacity limit in kilowatts. Some limits vary by customer type, technology and/or application. Other limits might also apply. This map generally does not address statutory changes until administrative rules have been adopted to implement such changes.
• Comparison of state net metering and interconnection rules
• Online with filters: able to view by key criterion and year
• Updated regularly, includes DSIRE data
• Collaborative effort, including IREC

Arizona: One of 15 “A” States in FTG
Not SRP
• ACC rules for all but Salt River Project
• No program cap, but program under review
• Facilities cap at 125% of customer’s load
• Rollover to end of year, then avoided cost payment
• Customer owns the RECs
• Third party ownership allowed / used for 90% of systems
• Meter aggregation not addressed
• 14,000 systems in APS service territory
Where Are We Heading?• Problems
– Concern about rate impacts is stalling program expansion, leading to proposed customer charges or VOSTs
– High up-front costs
– Gradually shifting utility peak demand to later hours
– No practical access to net metering (shading, renting, etc.)
• And Solutions– Rate Impact studies showing minimal impacts
– Costs plummeting / third party ownership (90% in AZ)
– Potential to load shift utility peak back to daytime
– New models opening new markets: aggregate net metering, virtual net metering, community solar, feed-in-tariffs
