Tampa Electric solar and battery rules for homeowners

Tampa Electric: solar and battery rules

What are TECO's rules for home solar and batteries?

Tampa Electric is an investor-owned utility and its net-metering programme is governed by Florida PSC Rule 25-6.065, including the tier structure and the requirement that a system is not expected to produce more than 115% of the home’s annual consumption.

How net metering works here

Interconnection tiers

Tiers under Florida PSC Rule 25-6.065, which governs TECO
Tier	System size	What it means
Tier 1	10 kW or less	Systems of 10 kW or less. The simplest interconnection path, and the tier most residential rooftop systems fall into.
Tier 2	Over 10 kW up to 100 kW	Systems above 10 kW and up to 100 kW. Additional insurance and interconnection study requirements apply compared with Tier 1.
Tier 3	Over 100 kW up to 2 MW	Systems above 100 kW and up to 2 MW. Commercial-scale requirements; outside the scope of typical residential projects.

The boundary at 10 kW is worth designing around. A system just above it moves into a tier with additional insurance and study requirements, and the extra process can cost more than the extra production is worth.

Common questions

Does TECO pay me for excess solar?

Not month to month. Exports accrue as kilowatt-hour credits that offset later consumption. Any credit left at the annual settlement is bought out at an avoided-cost rate, which is well below retail — which is why oversizing a system is poor economics.

How large a system can I install on TECO?

Under Florida PSC Rule 25-6.065 the system must not be expected to produce more than 115% of your annual consumption, and generating capacity is also limited relative to your service capacity. Systems of 10 kW or less use the simplest interconnection tier.

Is my address definitely served by TECO?

Check your bill. Florida service territories do not follow city limits, and an address near a boundary can be served by a different utility — which changes both the net-metering terms and the interconnection process.
