Net Energy Metering for Solar PV Systems

My Home » Content » Rebates » Net Energy Metering for Solar PV Systems

Invest in Renewable Energy

Customers who invest in renewable energy by installing photovoltaic (PV) systems for their home or business can interconnect with the GRU electric system and receive credit for the solar energy they do not use.

Getting Started

Before buying solar panels or beginning construction, contact GRU at 352-393-1460 for the most up-to-date information. We can help you decide which solar program will best meet your needs.

Program Offer

Customers will be reimbursed for the excess electricity generated by their PV system, measured in kilowatt hours (kWh).

In the event that excess kilowatt hours are exported to the city's electric distribution system beyond the kilowatt hours used by the customer during the billing cycle, such kilowatt hour balance will carry forward to be netted against kilowatt hours used by the customer during future billing cycles. If, at the end of each calendar year, the customer’s account contains a kilowatt hour credit balance, the customer shall be given a cash credit on their bill at the then – current avoided energy cost.  

Regardless of whether excess energy is delivered to the city's electric distribution system, the customer shall pay the applicable customer charge and/or the applicable demand charge for the maximum measured demand during each billing period pursuant to the applicable rate schedules.

Eligibility

  • Open to GRU electric customers.
  • PV modules must be UL- or ETL-listed.
  • Customer must obtain all necessary permits.
  • Final electrical connection must be performed by a licensed electrical contractor.
  • Tier 1 systems shall maintain general liability insurance for personal injury and property damage in an amount of not less than $100,000. For government entities, the policy coverage shall not exceed the entity’s maximum liability established by law and proof of self-insurance consistent with law shall satisfy this requirement.  
  • Tier 2 systems shall maintain general liability insurance for personal injury and property damage in an amount of at least  $300,000. For government entities, the policy coverage shall not exceed the entity’s maximum liability established by law and proof of self-insurance consistent with law shall satisfy this requirement.  
  • Tier 3 systems shall maintain general liability insurance for personal injury and property damage in an amount of at least $1,000,000. For government entities, the policy coverage shall not exceed the entity’s maximum liability established by law and proof of self-insurance consistent with law shall satisfy this requirement.  
  • Systems must comply with current City of Gainesville guidelines governing interconnection with the electric system and any subsequent revisions to these guidelines. Refer to GRU's Energy Delivery Service Guide for details.
  • Customer must sign an Interconnection Agreement.
  • An additional meter socket (REC meter) must be installed to interconnect with GRU so total system output can be captured.
  • Program details and rates are subject to change without notice.

Recommendations

  • Customer should consider getting a Solar Pathfinder report from the contractor that demonstrates that the PV system has a solar window of at least 70 percent and will not be shaded by trees, buildings or other structures.

Net Energy Metering (NEM) Process

  1. All email correspondence must be sent to DL_Solar@gru.com and the subject line must be the address where the system is or will be located.
  2. Contractor makes initial contact for new system(s) in an email. The request must include a specific location with a specific system size. This is to verify that the utility circuit has sufficient capacity for the system.
  3. GRU will respond to the new system request email and let the contractor know if that system could potentially be constructed on that circuit. This usually takes one to two business days.
  4. Once approval from GRU is received, contractor can submit an email with the following items (examples available in the Energy Delivery Service Guide, Section 8):

    • One-line electrical diagram (submitted by contractor)
    • Mounting elevation drawing (submitted by contractor) 
    • Location site plan (submitted by contractor) (Tier 2 and 3 only)
    • Solar panel layout (submitted by contractor) (Tier 2 and 3 only)
  5. GRU Engineering and Metering will review the drawings. If there are any issues, they will email you with any comments or concerns. This process usually takes eight to ten business days. If revisions to the drawings are requested, this step in the process can take much longer than the initially stated period.
  6. During step 4, the contractor or customer can submit the following completed documents:

  7. Once GRU has approved all of the drawings (Step 4) and has received all of the completed documents (Step 6), then the Interconnection Agreement is executed.
  8. Contractor installs solar PV system.
  9. The City or County Inspector will inspect the newly installed system and notify GRU. This step usually takes 2-3 business days.

    • Contractor emails a copy of the completed permit to GRU
    • GRU initiates the installation of the NEM and REC meters.
  10. GRU metering will perform set the new meters and perform an acceptance test. This step usually takes 2-3 business days.
