Interconnection & Net Energy Metering

Notice of Upcoming Net Energy Metering (NEM) Program Closure


On 10/12/16, BVES reached and exceeded its statutory 5% Net Energy Metering (NEM) limit. As a result, the current NEM Program will be closing, pending approval from the California Public Utility Commission (CPUC). While BVES waits for approval from the CPUC, the current NEM Program will remain available to customers until such date is provided by the Commission.

As a small investor owned utility (IOU), BVES is not subject to the same NEM requirements as California's largest IOUs. Accordingly, there is no requirement for BVES to continue NEM once the 5% cap is achieved. This is consistent with statutory and CPUC requirements. Also, the CPUC (and Legislature) have not provided clear direction for how BVES is to transition from its existing NEM program to any future program, should one be provided.

BVES prefers to have no gap between its existing NEM program and a long-term program to succeed its NEM program. However, given the lack of clear direction, and the time required to obtain CPUC-approval for any new programs, BVES anticipates some delay before a new, long-term renewable distributed generation program can be implemented to accommodate renewable customers that interconnect after the close of the NEM program.


A permanent post-NEM program for renewable distributed generation is under development. The permanent post-NEM program will have to be submitted to the CPUC by Application, which can be a lengthy process. Once that program is approved by the CPUC, BVES can provide additional details about that program. Check back here periodically for the status and details of a long term post-NEM program for renewable distributed generation.


Customers whose solar and/or wind projects are interconnected before the NEM closure will remain on the original NEM tariff for 20 years from the date of their original interconnection to BVES. After 20 years, they will be eligible for the successor tariff. Eligible customers who apply for solar and/or wind interconnection after the successor tariff is approved will qualify for that tariff.

Notice: Effective January 1, 2017, BVES will no longer allow customers to install their solar systems directly to a sub-panel, due to safety concerns and EUSERC requirements. See EUSERC Drawing 502 for compliance requirements.

Before You Get Started (see notice above)

The information in our Net Energy Metering (NEM) / "Customer Solar" Section will be helpful in answering most of your questions about Net Energy Metering and customer generation. This section has information for Residential & Small Commercial customers (30 kW or less), and Large Commercial customers (30 KW or more but no more than 1,000 kW).

What You Need To Apply

Please complete the forms included below prior to installation.

1) Application for Interconnection

2) Preliminary Service Request (PSR) - for Electric Service Panel Inspection

Before solar is built or installed, the Engineering Inspector needs to inspect the eletric meter panel to determine if the panel is complaint to today's standards (i.e. EUSERC rated).

3) Form 41 - Net Surplus Compensation

Required Plaques 

BVES requires that the electric service panel, AC disconnect and DC disconnect (when applicable) be labeled with plaques that meet the following requirements:

  • Red, hard plastic and permanently affixed
  • White engraving that is clearly legible
  • Cautionary language

Electric Service Panel Requirements and Example:

  1. Diagram of the structure on which the generation device is located
  2. Language denoting all electric power sources on or in the premises
  3. See example: Service Panel Plaque

AC Disconnect Requirements and Example:

  1. Nominal operating AC voltage
  2. Nominal operating AC frequency
  3. Maximum AC power
  4. Maximum AC current
  5. Maximum overcurrent device rating for AC module protection
  6. See example: AC Disconnect

DC Disconnect Requirements and Example:

  1. Open circuit voltage
  2. Operating voltage
  3. Maximum system voltage
  4. Operating current
  5. Short circuit current
  6. Maximum power
  7. See example: DC Disconnect

*If the above requirements are not met, permission to interconnect may be delayed by BVES.

Frequently Asked Questions (FAQs)

About NEM and Net Surplus Compensation (relatively new features of NEM):

Tariff Schedule NEM

The NEM rate described on this schedule explains how NEM works. The otherwise applicable tariff (OAT) doesn’t change but the way the Customer’s bill is calculated will change. Please read Sec. 5a that refers to system sizing and contact BVES if you have any questions. The system must be sized primarily to offset part or all of the customer’s own electrical requirements.

Sample Draft of Interconnection Agreement - For Customer Review Only (please do not fill this out)

After BVES receives a signed "job card" from the appropriate regulatory authority (city or county, depending on locale), BVES performs a final inspection of the new wind or solar system. Once that is complete, BVES countersigns and fully executes the Interconnection Agreement. The date BVES executes the agreement is the first date of the 12 month "Relevant period." BVES fills out the Interconnection Agreement based on the information supplied in the Application for Interconnection.

Rule 21 (applies to interconnection to the BVES system).

This is a utility’s formal set of rules for interconnecting to the BVES system. Applicable only if you are actually planning to move forward with installing generation.
