Virtual Net Metering (VNM)

Virtual Net Metering (VNM) allows energy produced by a renewable generating facility to be credited to the tenants' individual utility accounts who are connected at the same service delivery point. 

NEM-V vs MASH VNM

NEM-V and MASH-VNM rate schedules are identical, but the MASH-VNM rate, which provides equal benefits of renewable energy facilities to low income tenants, only applies to existing multifamily affordable housing which meets the definition of low-income residential housing as defined in Public Utilities Code 2852.

How VNM Works

Under Virtual Net Metering, the owner or operator of a multi-tenant property designates the percentage of the total metered output of the generator or generators, to be allocated to each tenant service account known as ‘Benefitting Accounts’.  The kilowatt-hours (kWhs) allocated to each Benefitting Account is subtracted from the tenant’s consumption resulting in a credit in the same manner as under Schedule NEM. If kilowatt-hours (kWh) credits exceed kilowatt-hours (kWh) use, those credits are carried forward to the next billing cycle, until the conclusion of the tenant’s 12-month ‘Relevant Period’.  

General Market

The NEM-V Rate Schedule  allows energy produced by a renewable generating facility to be credited to individually metered tenants who are connected at the same service delivery point1 or multiple generators connected to the same service delivery point and the same meter.

1 For purposes of VNM service the Service Delivery Point (SDP) is defined as the point where the distribution extension line drops from the utility’s primary distribution lines to deliver power to the customer. Extension lines that deliver power to other meters on the property are not considered separate service delivery points.

The combined capacity of generator(s) is limited to the cumulative coincident peak load of all Benefitting Accounts.

Multifamily Affordable Solar Housing (MASH)

The Multifamily Affordable Solar Housing (MASH) program, part of the California Solar Initiative (CSI), is designed to subsidize PV systems in multifamily housing which will offset electricity loads and provide economic benefits for housing property owners and managers as well as building tenants. Learn More about the MASH program.

The MASH-VNM Rate Schedule allows MASH program participants to apply the credits from a single solar system to multiple accounts at an eligible low income building.

VNM Metering & Billing

The NEM-V Rate Schedule requires a $25 one-time set up charge per newly established Benefitting Account, with a $500 cap per arrangement. There is no charge for up to one change per Benefitting Account per 12 month period. A $7.50 charge per account change applies to subsequent changes within the 12 month period.

SCE will inform the Owner at the site assessment about what reasonable disconnect/reconnect procedure charges they may expect at the time of interconnection. Cost for disconnect/reconnect will vary depending on the number of hours required to complete this work based on factors including but not limited to: grounding or splicing requirements, effect of disconnect on multiple customers, SCE’s need to stand by during customer performed work or if the disconnect/reconnect occurs outside normal business hours.  A site assessment charge could range from $0-$5,000.
