Kentucky Clean Energy Guide

Kentucky's utility-scale solar fleet roughly tripled in 2025 — from 426 MW at the end of 2024 to about 1,226 MW across 20 operating farms — in a state with no renewable portfolio standard, zero operating wind farms, and a legislature that keeps rewriting the siting rules. This guide covers who is building, who is buying the power, and where the fights are.

The headline number understates how fast this market moved. EIA's Kentucky Electricity Profile showed just 426.1 MW of utility-scale solar at the end of 2024; by mid-2026, Cleanview counted 20 operating utility-scale solar farms totaling 1,226 MW, after Sebree, Green River, Unbridled, Bluebird, and Ashwood all came online. That buildout happened with essentially no state policy support — Kentucky ranks 41st for operating clean power capacity, and wind, solar, and storage still supply only about 2.8% of in-state generation (46th nationally). Coal provided 67% of Kentucky's electricity in 2024 and natural gas another 26%.

What is pulling projects online is corporate demand, not mandates: Nucor, Toyota, Meta, GM, and Kentucky's municipal power agency have contracted for nearly all of the state's large solar output. Meanwhile the load side of the ledger is exploding — utilities statewide report data center requests exceeding 10 GW — and the legislature has responded by subsidizing the demand while tightening the screws on the supply. That tension defines Kentucky's market.

Policy: No Mandates, and Laws That Lean Toward Coal

Kentucky has no renewable portfolio standard, no clean energy standard, and not even a voluntary renewable energy goal — a status confirmed unchanged through the 2026 legislative session. Recent statutes actively lean the other way: Senate Bill 4 (2023) and Senate Bill 349 (2024) make it harder for utilities to retire fossil-fuel power plants and largely prevent intermittent renewables from counting as replacement capacity for retired coal units. SB 349 also created the Energy Planning and Inventory Commission (EPIC) at the University of Kentucky, whose analyses now shape the data center debate.

Net Metering After SB 100

Net metering is required of investor-owned utilities and PSC-regulated electric cooperatives (TVA-served utilities are exempt) under a statute first enacted in 2004 and expanded in 2008. SB 100 (2019) raised the system cap from 30 kW to 45 kW but ended one-for-one kWh netting for new customers: the PSC now sets dollar-denominated export credit rates utility by utility in rate cases. Utilities may also petition to limit new net metering once cumulative net-metered capacity hits 1% of their single-hour peak load. Kentucky offers no state solar tax credit.

The 2025–2026 Legislative Whiplash

The past two sessions produced a rapid-fire sequence of energy laws — most of them aimed at load, siting, or nuclear rather than renewables:

• HB 775 (2025): Expanded the 50-year data center sales-and-use tax exemption from Jefferson County to every county, with investment thresholds scaled by population — $450 million in counties over 100,000 residents, $100 million for 50,000–100,000, and $25 million below that. Google and Meta lobbied for the law.
• HB 790 (2025): Would have imposed a 350-foot property-line setback on merchant solar in counties without zoning; introduced February 19, 2025 by House energy committee leadership but not enacted.
• HB 677 (2026): Became law without the governor's signature. Nominally a carbon-sequestration bill, a Senate committee substitute bolted on siting changes: the existing 2,000-foot merchant-plant setback now covers ancillary structures including battery storage, a new 1,000-foot property-line setback applies to PSC-regulated utility-built solar and wind, merchant wind turbines are capped at 350 feet hub height, and decommissioning bond requirements were tightened.
• HB 869 (2026): Passed April 15, 2026, and promptly rolled back parts of HB 677 — removing storage from the merchant-facility setback provisions and relaxing the decommissioning bond rules.
• SB 57 (2026): Created a Nuclear Reactor Site Readiness Pilot Program with grants up to $25 million per project and lets regulated utilities recover nuclear permitting and licensing costs from ratepayers.
• HB 593 and HB 544 (2026): Competing data-center guardrail bills — HB 593 would have required a $75,000 application fee and dedicated resources for loads over 250 MW. HB 593 passed the House but died in a Senate committee; neither became law, leaving cost-allocation questions to the PSC.

The Projects: Corporate Offtake Built Kentucky's Solar Fleet

Nearly every major Kentucky solar project has a named corporate or municipal buyer behind it. The pattern is unmistakable — manufacturers and tech companies, not utility procurement, are financing this fleet:

• Sebree Solar I (Henderson County): 250 MW, NextEra Energy Resources — the largest solar farm in Kentucky, online September 2025. Nucor holds a 250 MW PPA tied to its Gallatin steel mill; a 150 MW Sebree Solar II phase was slated to follow.
• Green River Solar (Meade/Breckinridge counties): 200 MW, NextEra, commercial operation May 2025 on roughly 1,200 acres, with about $10 million in revenue to the two counties over the project's life.
• SR Russellville (Logan County): 173 MW, Silicon Ranch, online September 2024 with roughly 500,000 panels. Output flows through TVA arrangements — 145 MW supporting Meta's regional data center operations and 28 MW for GM's Bowling Green Assembly plant.
• Unbridled Solar (Henderson/Webster counties): 160 MW, National Grid Renewables (now Geronimo Power), online March 2025 across roughly 1,500 acres; projected at $42 million in direct economic impact and $11.4 million in tax revenue over its first 20 years.
• Martin County Solar Project: 111 MW, Savion with Edelen Renewables, commercial operation December 2024 — built on the reclaimed Martiki mountaintop coal mine in eastern Kentucky, with 300-plus construction jobs and a 100 MW Toyota virtual PPA.
• Ashwood Solar I (Lyon County): 86 MW, RWE's first Kentucky solar project, commissioned June 25, 2025. The Kentucky Municipal Energy Agency (KYMEA) takes all output under a 20-year PPA.
• Wood Duck Solar (Barren County, pipeline): 100 MW, Geenex Solar — received its siting board construction certificate November 14, 2025 over strong local opposition, with construction possible as early as Q1 2026 and in-service targeted for late 2027 or early 2028.

Notice what is missing: wind and batteries. Kentucky has zero operating utility-scale wind farms, and HB 677's 350-foot hub-height cap makes modern merchant turbines effectively unbuildable. Battery storage is similarly absent — in October 2025 the PSC rejected LG&E and KU's proposed Louisville battery facility even as it approved two new gas plants.

Siting: One State Board, Two-Thirds of Counties Without Zoning

Merchant generating projects of 10 MW or more need a construction certificate from the Kentucky State Board on Electric Generation and Transmission Siting, created in 2002 and housed at the Public Service Commission. Projects must also comply with local planning and zoning where it exists — but roughly two-thirds of Kentucky counties have no zoning at all, making the Siting Board the only permitting forum across most of the state. Statute sets a 2,000-foot setback from residential neighborhoods, schools, hospitals, and nursing homes, but the board can and routinely does grant deviations — past approvals have allowed setbacks as low as 25 feet. It also attaches mitigation conditions: Summer Shade Solar's 106 MW Metcalfe County project was approved October 24, 2025 with 40 conditions, and Lost City Renewables won conditional approval for a roughly 250 MW project in Muhlenberg County.

Utility-built projects follow a different track — a CPCN plus site compatibility review, which since HB 677 includes the new 1,000-foot property-line setback for utility solar and wind.

Where Opposition Is Winning — and Where It Isn't

The Wood Duck Solar fight in Barren County is the state's defining siting battle. Geenex's 100 MW, roughly 2,300-acre project drew a 575-signature opposition petition, letters from the local Amish community, and packed hearings in July and October 2025, with concerns ranging from Mammoth Cave-area karst and cave shrimp habitat to fire risk and property values. Barren County's fiscal court passed a solar ordinance in May 2025 and the judge-executive refused any PILOT agreement or industrial revenue bonds. None of it mattered to the outcome: the state siting board issued the construction certificate on November 14, 2025. That is the structural reality of Kentucky siting — counties can protest, but in unzoned territory they cannot veto.

Where counties do have land-use tools, they are using them. Daviess County's fiscal court voted 3–1 in February 2025 to impose a 12-month moratorium on wind and solar projects after residents opposed a roughly 1,200-acre solar proposal near Owensboro. Breckinridge County approved a moratorium on larger solar applications on November 18, 2024. Henderson County — home to the Sebree and Unbridled projects — publicly weighed a two-year pause on new solar in November 2024 while studying drainage, screening, wildlife, and glare. In Green County, residents filed opposition comments against the proposed Exie Solar merchant project in an August 2025 siting board case. And the backlash is no longer solar-only: a May 2026 draft ordinance in Lexington would effectively bar hyperscale data centers, even as the state courts them with tax breaks.

Demand: 12 GW of Data Center Requests in an 18 GW State

Data centers are Kentucky's dominant new load story, and the numbers are staggering relative to the system's size. LG&E and KU told the PSC in March 2026 that they had 29 potential data center projects in the pipeline — 11 of them, totaling about 3.5 GW, rated at 50%-plus probability — with total prospective demand approaching 12 GW. For context, Kentucky's maximum statewide generation in 2024 was 18.4 GW. Statewide, utilities report data center requests exceeding 10 GW.

Regulators are answering that demand with gas, not renewables. On October 28, 2025, the PSC approved roughly $2.8 billion for LG&E and KU: two 645 MW natural gas combined-cycle plants — one in Louisville, one in Mercer County — plus upgrades keeping the Ghent 2 coal unit running year-round, all justified by a forecast 1.75 GW of data center demand by 2032, a 29% peak-demand increase. The same order rejected the companies' proposed Louisville battery storage facility and a request to extend a Louisville coal unit past its 2027 retirement.

The first big campus is already underway: the PowerHouse/Poe Companies data center on Camp Ground Road in southwest Louisville, with LG&E contracted for an initial 335 MW expanding to 402 MW near-term and a first 130 MW phase targeting commercial operation in late 2026. Estimates put the campus's ultimate draw at up to 525 MW — nearly the full output of the 691 MW Cane Run gas plant. HB 775's statewide 50-year sales-tax exemption is the recruiting pitch; the guardrail bills that would have made data centers pay their own way died in the 2026 session.

Kentucky's eastern utilities are also importing the regional consequences of this boom. PJM's capacity auction cleared at $329.17/MW-day for 2026/27 — up 22%, at the FERC-approved cap — and $333.44/MW-day for 2027/28, price signals driven by data-center-fueled scarcity across the RTO that flow directly into bills for Kentucky Power, Duke Energy Kentucky, and EKPC customers. In a state whose 10.07 cents/kWh average retail price has long ranked among the lowest ten nationally, that trajectory is politically explosive.

Challenges & Outlook

The bear case writes itself: no RPS, statutes that protect coal retirements from happening, a siting law rewritten twice in two years, county moratoriums spreading, zero wind, zero meaningful storage, and a regulator that just chose gas over batteries. Renewables were about 7.1% of 2024 generation — most of it legacy hydro — in a state that generated 66.95 TWh.

The bull case is in the pipeline math. Atlas Public Policy counts roughly $4 billion in Kentucky clean energy investment including planned projects, ranking the state 20th for planned clean energy development and 3rd nationally for its ratio of planned-to-existing clean power — the profile of a late starter accelerating hard. Corporate offtakers keep signing: the Nucor, Toyota, Meta, GM, and KYMEA deals that built the current fleet show demand for Kentucky solar that does not depend on Frankfort's blessing. With 12 GW of prospective data center load chasing an 18.4 GW system, Kentucky will need every megawatt it can build — and solar on cheap, unzoned land remains the fastest thing anyone can build here. Clean power already supports 15,100 jobs and enough generation to power 153,000 homes; the question is whether the siting backlash or the load growth wins the next legislative session.
