Why solar in Hopkinsville

Kentucky net metering law excludes TVA, and TVA supplies this part of the state through local power companies. So the arrangement that matters in Hopkinsville is the TVA one: residential exports purchased at avoided cost through Dispersed Power Production, rather than credited at the retail rate. That is a materially different proposition from the full retail net metering available a few hours east, and it changes what a good system looks like.

The TVA framework, briefly

Kentucky law requires investor-owned utilities and electric cooperatives to offer net metering but excludes TVA, which supplies much of western Kentucky through local power companies.

Under TVA Dispersed Power Production, a residential customer may sell excess generation to TVA at TVA avoided cost, a wholesale-style measure well below the retail price of electricity.

An interconnection agreement with your local power company is required to participate, and TVA Green Connect is the route that arranges it along with access to TVA-approved contractors.

So there are two organisations involved: TVA sets the framework and buys the exports, while your local power company handles the interconnection, the fees and the timeline.

What avoided-cost export does to a design

Electricity you consume at the moment it is generated displaces a purchase at the full retail rate. Electricity you export earns avoided cost. Those are very different amounts.

So annual production is not a useful summary of what a system is worth. What matters is how much of that production your household absorbs as it happens.

The marginal panel at the top of a design produces mostly exports, earning a fraction of retail while costing full price, so the return on each additional panel falls as the system grows.

A system covering roughly 70 to 80 percent of annual consumption frequently returns better than one covering 100 percent under this kind of arrangement. Ask for a smaller design modelled alongside the proposal.

The levers that help

Shifting flexible loads into daylight converts avoided-cost exports into full-value avoided purchases at no cost. Dishwasher, laundry, pool pump and electric vehicle charging all move easily.

Pre-cooling on hot afternoons is usually the largest free lever, because air conditioning is the biggest load in a Kentucky summer and it runs hardest when generation peaks.

Storage does the same automatically and at scale, and under an avoided-cost arrangement it does genuine arbitrage rather than only providing outage resilience.

Ask for the system modelled with and without storage so the incremental value is a visible number, and ask what round-trip losses the model assumed.

Rebuilding the arithmetic on Kentucky terms

The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase receives no federal tax credit, and Kentucky has no state solar tax credit.

Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.

What exists is full retail value for electricity consumed as it is generated, TVA avoided cost for exports, and whatever your local power company charges in fixed monthly costs.

Ask for the projection with those separated, the self-consumption share stated, and the interconnection timeline committed in writing by your installer.

Incentives & rebates

Net metering: Full retail at LG&E and KU; avoided cost at Duke Kentucky

Kentucky law requires investor-owned utilities and electric cooperatives, excluding TVA, to offer net metering to customers with qualifying solar systems, and Senate Bill 100 raised the eligible system size from 30 kW to 45 kW. Compensation is overseen by the Kentucky Public Service Commission and set per utility, which has produced a genuinely split market. LG&E and Kentucky Utilities customers still receive full retail net metering, with exported electricity credited at the same rate they pay for it. That is now unusual: most neighbouring states have moved away from retail-rate credit in the last few years, and it is the single most valuable feature of solar in those territories. Duke Energy Kentucky moved in the other direction, introducing Rider NM II on January 1, 2025 to comply with a Commission order. Under NM II excess generation is credited at an avoided cost rate published at $0.062924 per kWh for residential customers, against a Kentucky residential average around 15 cents per kWh, so roughly 40 percent of retail. Systems in service by December 31, 2024 were grandfathered onto the previous Net Metering I rider for 25 years. An appeal against the Commission approval of NM II is pending in Franklin Circuit Court, so the position is not finally settled. Separately, TVA supplies much of western Kentucky through local power companies and municipal utilities, which sit outside the state requirement entirely and compensate exports at TVA avoided cost. The practical result is that the first question about any Kentucky solar quote is which utility bills the address.

Frequently asked questions

Does Kentucky net metering apply in Hopkinsville?

The state requirement excludes TVA, which supplies much of western Kentucky through local power companies. Residential exports here are handled through TVA Dispersed Power Production at avoided cost rather than credited at the retail rate.

Who do I deal with for interconnection?

Both TVA and your local power company. TVA sets the framework and buys the exports at avoided cost, while your local power company handles the interconnection agreement, the fees and the timeline. Green Connect is the route that arranges it.

How should that change my system size?

Size to your daytime load rather than your annual total. Under avoided-cost export a system covering roughly 70 to 80 percent of annual consumption frequently returns better than one covering 100 percent.

What can I do without spending more?

Shift flexible loads into daylight. Dishwasher, laundry, pool pump and electric vehicle charging all move easily, and pre-cooling on hot afternoons is usually the largest free lever since air conditioning peaks with generation.
