Solar Meter Aggregation: Regulations Have Not Changed Yet For Multiple Meter Owners

Updated 11/21/2023


Solar energy systems are an excellent source of renewable energy that can reduce costs, increase profits, and decrease carbon emissions. However, many businesses face the challenge of having multiple energy meters and some in locations that are less than ideal for solar. This is where meter aggregation can come in handy.

Meter aggregation is a system that allows a single photovoltaic system to be connected to one meter and generate energy credits that offset multiple meters at the same time. This innovative technology was introduced in 2014 by the California Public Utilities Commission (CPUC) and has provided many opportunities for California’s agricultural industry. However, meter aggregation offers a range of benefits that can also make it an attractive option for businesses and homeowners.

One of the primary advantages is that it enables businesses or individuals with multiple meters on their property to offset multiple energy loads with just one single solar system. This flexibility provides great advantages for system placement and allows you to save on installation costs, making it a cost-effective solution. This can also translate to improved return on investment (ROI) for businesses.

How Does Solar Meter Aggregation Work? 

Aggregated meters must be located on continuous land parcels owned or leased by the same entity. Parcels divided by public thoroughfares are still considered contiguous, and system sizes are limited to Mega Watt (AC) arrangements. Additionally, the following Net Energy Metering rules are applicable for aggregated systems: 

  • Energy generation is credited at retail energy rates, including “Time-Of-Use” (TOU) energy pricing.
  • Only the energy charges of your utility bill can be offset; monthly demand and service charges still apply.
  • There is a one-time $20 set-up fee per meter, and $5 fee per meter, per month.

The benefits of meter aggregation are not just limited to reducing energy costs. It also provides a unique solution to rising utility costs that may be especially advantageous for energy users with multiple small and mid-sized loads. Solar Meter Aggregation still receives the more advantageous Net Energy Metering (NEM2.0)  and does not abide by the same rates as new NEM 3.0, meaning you continue to save big for years to come! 

Aggregated solar systems allow agricultural, commercial, and residential accounts to be combined, providing more options and flexibility to businesses and homeowners alike. This flexibility also allows for adjustments to your meter portfolio annually, making it an even more attractive option. Those that take advantage of meter aggregation technology can also reduce their carbon footprint. 

So, if you’re looking to save money and make a positive impact on the environment, meter aggregation may be the perfect solution for you.
