Preservation districts
Solar in a Louisville local preservation district, such as Old Louisville or Clifton, needs a Certificate of Appropriateness reviewed by the Office of Planning and Design before installation.

In Louisville, an energy decision can outlast the roof under it. We give LG&E customers and their neighbors in Oldham, Bullitt, and Shelby counties an independent read on solar proposals, preservation reviews, and green power contracts.
Where the river meets the grid, a city's energy decisions flow downstream for decades.
In Louisville, an energy decision tends to outlast the people who made it: a 25-year lease on a Highlands bungalow, a renewable contract signed by a hospital’s facilities director, a church roof the next three treasurers will inherit. As an independent solar consultant for Louisville, KY, we give homeowners, businesses, and institutions a plain-English read on the numbers before those decisions are locked in.
We’re fee-only. We don’t sell, install, or earn commissions, and no installer, lender, or developer pays us.
LG&E serves Louisville and 16 surrounding counties. New net metering customers are on NMS-2, which pays a dollar credit for each kilowatt-hour sent to the grid. In its February 2026 rate order, the PSC kept the residential credit at about 7.1 cents while approving higher base rates.
Here’s what that means in practice. A household that exports 3,000 kWh a year earns roughly $213 in bill credits for that energy. The same 3,000 kWh used inside the house while the panels produce would have avoided the full per-kWh charges instead. That gap grows each time base rates rise and the credit doesn’t. A Louisville proposal that never states how much you’ll export is leaving out the number that matters most.
Louisville Metro regulates solar through Section 4.3.16 of its Land Development Code. In local preservation districts, including Old Louisville and Clifton, solar needs a Certificate of Appropriateness reviewed by the Office of Planning and Design. Build that review into the schedule before signing an installation contract with a firm start date. Our Approval & Incentive Packets service organizes and tracks the application; drawings and technical details come from your installer.
Large Louisville buildings have more choices than rooftop panels alone. LG&E and KU’s Green Tariff lets businesses buy RECs, host on-site solar through the Business Solar option, or, for large customers, sign a Renewable Power Agreement for power from new renewable projects. We compare those paths with on-site solar on cost, contract length, and what each lets you claim, and our Carbon & Scope 2 Reporting turns the result into numbers your board or customers can use.
Past the Gene Snyder Freeway (I-265), the map changes. Shelby Energy, Salt River Electric, and Nolin RECC, all EKPC member co-ops, serve parts of Oldham, Shelby, Bullitt, Spencer, and nearby counties, each under its own tariff. A farm outside Shelbyville and a house in St. Matthews can face different rules in the same week. If a system there is already running and underperforming, a System Health Check compares it with an expected baseline.
Who sends the bill
Your utility's tariff shapes the math more than your roof does. Here's who serves the area, and what that tends to mean.

EKPC member co-op headquartered in Bardstown; serves Bullitt, Nelson, and Spencer counties and parts of Jefferson and others nearby.
EKPC member co-op based in Shelbyville; serves Shelby, Oldham, Henry, and Trimble counties and part of Jefferson, among others.
EKPC member co-op based in Elizabethtown; its territory reaches into Bullitt, Hardin, and Meade counties.
Local notes
Solar in a Louisville local preservation district, such as Old Louisville or Clifton, needs a Certificate of Appropriateness reviewed by the Office of Planning and Design before installation.
LG&E's base rates went up in 2026 while the NMS-2 credit held steady. Solar used inside the building gained value; exported solar didn't.
Hospitals, warehouses, and plants can weigh on-site solar against LG&E and KU's Green Tariff, including a Renewable Power Agreement for power from new renewable projects.
Older neighborhoods have big trees. A production estimate that ignores the oak next door is optimistic, so ask whether shade was measured on site.

Yes. Louisville Metro requires a Certificate of Appropriateness for solar in a local preservation district, reviewed by the Office of Planning and Design. We organize the application packet and track it; drawings and technical details come from your installer.
New net metering customers on NMS-2 receive a dollar bill credit for each exported kWh. The PSC's February 2026 order kept the residential credit at about 7.1 cents. Check the current tariff before you sign, because later cases can change it.
It depends on what you need to claim, how long you can commit, and the condition of your roof. We compare the options side by side, including who holds the renewable energy certificates in each.
When it helps, yes, for example for a board presentation or a larger commercial project. Most Louisville work runs by video and shared documents, which keeps the engagement efficient.
