Compensation and Billing 

This page explores your billing and compensation as an AMP customer with a grid interconnected solar generation system.

How Interconnection Works

  • When you generate your own electricity, the immediate energy needs of your home or business will be served first, reducing the amount of energy you pull from the grid.  
  • Any surplus energy you generate but do not consume will be exported back to the electric grid.
  • In the same way, any additional power you require - day or night - is automatically supplied by AMP.
  • Interconnection to the grid allows you to continue to receive the reliable service you are accustomed to as an AMP customer.

Net Energy Metering (NEM)

Net Energy Metering, or NEM, is a special rate schedule for interconnected solar and renewable generation customers. By law, NEM is available to all new renewable self-generation customers until total installed renewable capacity is equal to the NEM Capacity Value (defined as 5% of aggregate customer demand). The NEM Capacity Value is reviewed annually, and currently equals 3.6 MW. Existing installations in Alameda make up 2.2 MW, leaving 1.4 MW of NEM capacity to be filled.

New renewable generation customers will be billed under AMP's Net Energy Metering (NEM) program until the NEM capacity is reached. Once the NEM capacity value is reached, new customers will be billed under an alternate rate schedule. Existing NEM customers will continue to be billed under the NEM according to the terms of their NEM agreement, which lasts for a period of 20 years starting on the date of interconnection. For more information on Net Energy Metering, please refer to the NEM Rider.

How Net Energy Metering Works
  • Under NEM, AMP keeps track of all electricity flowing in and out of the property with a specialized net energy meter.

  • When you generate more electricity than you use in a month, you get a credit at full retail rate value for excess energy exported to the grid.

  • This credit can be used to offset energy drawn from the grid during months when you use more than you generate.

  • Every 12 months, roughly at the anniversary of interconenction to the grid, AMP zeros out any remaining credits that were not used during the year.

  • AMP provides compensation for the remaining credits that were not used at a rate equal to the average of AMP's purchases of renewable generation, currently 5.7 cents per kWh.

Annual True-Up Statement 

You will receive a true-up statement every 12 months, roughly on the anniversary of when you installed your system.

  • Depending on your usage and generation over the year, your true-up statement will be either be in the form of a check for the balance AMP owes you, or a bill for the balance you owe AMP.

  • Generally, if your system generated more electricity than your home used over the year, you will receive a check. If your home used more electrcity than your system generated over a year, you will receive a bill.

  • To complete the true-up, AMP balances your monthly energy charges, monthly energy credits, and additional taxes and fees.
    • If you generated more energy than you used, your true-up will include: refund for the electricity charges you paid on a monthly basis; compensation for the net surplus energy you generated; and charges for remaining taxes and fees.
    • If you used more energy than you generated, your true-up will include: any remaining electricity charges; and charges for remaining taxes and fees.
