Solar Compensation & Billing

Alameda Municipal Power (AMP) customers who install solar systems are placed on the Eligible Renewable Generation (ERG) plan.

Understanding the ERG Plan

ERG, a special rate plan for new renewable generation customers, went into effect on December 31, 2016. 

The ERG plan does not affect customers in the net energy metering (NEM) plan. 

How the ERG Plan Works

  • Customers will be paid monthly with a bill credit for the excess energy they deliver to AMP’s power grid.
  • The bill credit will amount to the cost of the renewable energy that AMP won’t need to buy, as a result of using the customer’s solar energy.
  • You’ll be billed monthly for the energy AMP delivers to you.
  • Currently AMP provides compensation for the remaining credits that were not used at the rate of $0.10515 per kWh. (For details, see Rider ERG (PDF)
  • You will not need to get a separate Energy Generation (EG) meter.

Application Fee

A non-refundable interconnection application fee is required for all new commercial solar and energy storage projects as well as existing NEM customers adding battery storage.

  • As of November 1, 2022 the $330 interconnection fee is being waived for residential customers whose interconnection application is dated on or after November 1, 2022.
    • Fees are only waived for residential buildings built before January 1st, 2020.
  • For commercial and multi-family installations up to 50 kilowatts, the fee is $660.
  • There is a minimum fee of $1,100 for installations greater than 50 kilowatts. AMP will provide an estimate for these fees if they exceed $1,100.


AMP’s Net Energy Metering (NEM) compensation plan closed to new customers in August 2017. Existing NEM customers stay in the plan for 20 years from their interconnect date.
