What is Net Metering Aggregation, and How Does it Work?

Net Metering Aggregation also known as, meter aggregation and Net Energy Metering Aggregation (NEMA) broadens the advantages of Net Metering for enterprises equipped with numerous solar energy systems, all while being powered by non-solar metered electricity on the same premises. This innovative approach allows businesses to harness the combined energy output of multiple solar installations, optimizing the overall efficiency of their renewable energy initiatives.

By leveraging NEMA, businesses can consolidate the energy generated by various solar systems and offset the consumption of traditionally sourced electricity. This streamlined integration not only enhances the sustainability profile of the organization but also contributes to greater cost savings and environmental impact reduction.

Furthermore, NEMA facilitates a more comprehensive and centralized monitoring system, enabling businesses to track and manage the collective performance of their solar energy assets. This enhanced oversight ensures optimal utilization of renewable resources, allowing for data-driven decisions to improve overall energy efficiency.

In essence, Net Energy Metering Aggregation empowers businesses with multiple solar installations to amplify the benefits of Net Metering, fostering a more sustainable and economically advantageous energy ecosystem. As organizations continue to prioritize environmentally conscious practices, NEMA emerges as a strategic tool to maximize the potential of solar energy investments for a brighter and greener future.

Net Metering

Net Metering enables users of grid-tied solar systems to sell surplus energy back to utilities, earning credits applied to their electricity bills. For solar users with electricity needs across multiple sites and meters—such as agriculture businesses with dispersed facilities like buildings, pumps, and other electric equipment—Net Energy Metering Aggregation (NEMA) extends the benefit. NEMA enables them to credit solar power production against the total electrical usage of the entire business, going beyond the facilities directly connected to the solar installation.

In the past, Net Metering was limited to the electrical usage measured on the meter attached to a specific solar system. However, NEMA introduces a more comprehensive approach, allowing businesses to maximize the advantages of solar energy across their entire electrical consumption. This inclusive feature recognizes businesses diverse energy needs with dispersed operations and contributes to a more efficient and cost-effective energy landscape.

Net Metering Aggregation NEMA presents a transformative approach to renewable energy project design, making a single large PV system as impactful as numerous smaller systems dispersed across multiple fields. This innovation is a more efficient and practical strategy for implementing renewable energy projects without aggregate net Metering agriculture businesses with diverse metered locations face challenges in obtaining full credit for all solar energy production.

The beauty of aggregate net Metering lies in its ability to integrate multiple meters under different rate plans. For instance, a residence on a ranch may fall under residential rates, while a pump station may be subject to commercial or agricultural rates. NEMA enables solar customers participating in net metering programs to amalgamate the excess power generated across these varied rate plans and sell it back to utility companies.

In California, NEMA is accessible to PG&E, SCE, and SDG&E customers, as well as certain customers of other public and private utilities. The enrollment process involves a $25 sign-up fee (capped at a maximum of $500) for each meter, along with a $5 per month billing charge. This inclusive approach makes NEMA a valuable tool for a broad spectrum of consumers, fostering greater flexibility and financial viability in adopting solar energy.

Requirements for Net Metering Aggregation (NEMA)

The California Climate and Agriculture Network outlines specific requirements for those seeking to participate in the Net Energy Metering Aggregation (NEMA) program. These criteria, established to ensure compliance and effective operation, are as follows:

1. Ownership or Leasing Consistency:

  • All renewable energy producers utilizing Net Energy Metering can apply for NEMA.
  • The land hosting all meters must be owned, leased, or rented by the same customer. Proof of this is required, typically in the form of submitted parcel maps.

2. Geographical Continuity:

  • All meters must be situated on adjacent parcels and connected in an uninterrupted chain to the parcel designated as the Generating Account.
  • Parcels divided solely by a road are acceptable within this contiguous arrangement.

3. Single Generating Account:

  • Each NEMA arrangement is limited to one Generating Account; in cases where there are multiple systems, a separate NEMA arrangement must be created for each system.

Notably, the California NEMA program was introduced in early 2014 through the enactment of Senate Bill 594. However, in 2016, there was an attempt by California’s Investor-Owned Utilities (IOUs) to phase out the program. Strong advocacy efforts by solar users and IOUs, directed towards the California Public Utilities Commission (CPUC), led to a decision in January 2016 to largely preserve the NEMA program, highlighting its continued relevance and importance in the state’s renewable energy landscape.

How You Can Benefit From Net Metering Aggregation

Adopting Net Metering Aggregation for solar systems presents an advantageous solution to address the challenges of increasing energy costs. Meter aggregation, in particular, offers significant benefits, especially for energy users managing multiple small and mid-sized loads.

1. Combination of Accounts:

Aggregated solar systems allow the integration of agricultural, commercial, and residential accounts. This means that energy generated from diverse sources can be combined, providing a more versatile and comprehensive approach to meeting the energy needs of various sectors.

2. Flexibility in Meter Portfolio:

 Meter aggregation offers the flexibility to make adjustments to your meter portfolio on an annual basis. This adaptability is valuable for accommodating changes in energy usage patterns, ensuring that your aggregated solar systems align with the evolving needs of your agricultural, commercial, or residential operations.

Users can optimize their energy utilization, reduce costs, and contribute to a more sustainable and resilient energy infrastructure by leveraging aggregation. This approach addresses immediate concerns about rising energy expenses and promotes long-term efficiency and environmental responsibility across diverse sectors.
