Gainesville Regional Utilities distributed generation interconnection: tiers, fees and insurance

How the size is measured

the DC power rating in kW. GRU writes every tier boundary in kW DC and applies no DC to AC conversion factor, so the array rating itself sets the tier.

Size bands and what each one obliges

Tier 1 Size 0 to 10 kW	10 kW DC or less. No application fee is listed. The agreement requires liability insurance of not less than $100,000. Interconnection agreement Letter of Intent and capacity check before design $100,000 liability insurance per the agreement
Tier 2 Size 10.001 to 100 kW	Greater than 10 kW DC and up to 100 kW DC. A one time $400 application fee is charged to the utility bill and is non refundable. The agreement states insurance of at least $300,000 while the GRU web page states $1,000,000, so confirm before quoting. $400 non refundable application fee Liability insurance, amount disputed between GRU sources Interconnection agreement
Tier 3 Size 100.001 to 2000 kW	Greater than 100 kW DC and up to 2 MW DC. A one time $1,000 non refundable application fee applies. The agreement states insurance of at least $1,000,000 while the GRU web page states $2,000,000. The owner pays all system impact study costs and GRU will not approve interconnection until the study is complete. $1,000 non refundable application fee Liability insurance, amount disputed between GRU sources System impact study at owner cost

The screens that decide it

Within the 2 MW DC ceiling Limit 2000 kW.
GRU tiers stop at 2 MW DC.
Below the 250 kW DC telemetry threshold Limit 250 kW.
At a nameplate rating of 250 kW DC or greater, GRU installs telemetry and metering equipment at the owner expense. Budget for it.

Ask the utility this, before you sell it

GRU publishes two different insurance schedules. The interconnection agreement says $100,000, $300,000 and $1,000,000 by tier while the net metering web page says $100,000, $1,000,000 and $2,000,000. Which governs this application?
Does the circuit at this address have sufficient capacity, and is the proposed system considered oversized? GRU screens this through the Letter of Intent and publishes no percentage.
Confirm the export credit rate. GRU credits excess energy at the fuel adjustment rate, listed at $0.0350 per kWh in the FY2025 rate sheet, against a residential retail energy charge of $0.0846 below 850 kWh and $0.1121 above it.

Worth knowing before you quote

GRU is not retail net metering. Excess energy is credited at the fuel adjustment rate, roughly a third of the retail energy charge above 850 kWh, and is trued up annually at an avoided cost price GRU reserves the right to modify at any time without prior notice. Economics in Gainesville are driven by self consumption, not export. The feed in tariff is closed to new applicants. A $100 failure to show fee applies when a contractor misses a scheduled meter set appointment. Approvals are honored for one year and rescinded after a year of inactivity. GRU publishes no consumption cap, no aggregate cap, no storage provision and no committed days to permission to operate.
