Xcel Energy’s Colorado subsidiary has petitioned the state Supreme Court to overturn a district court ruling that blocked its use of eminent domain for a 550-foot easement needed to interconnect more than 1 gigawatt of nearly complete wind generation, a case that could define whether utilities can secure minimal land rights for transmission when landowners refuse to negotiate. The utility argues the interconnection delay is already costing ratepayers millions in lost production tax credits and higher replacement power costs, while the landowner contends the taking serves private rather than public interest. The outcome will set precedent for how Colorado – and potentially other states – balance property rights against the infrastructure needs of a decarbonizing grid.
Transmission Easements Become Flashpoint in Clean Energy Buildout
The dispute centers on Public Service Company of Colorado’s (PSCo) Rush Creek and Cheyenne Ridge wind projects, two facilities in eastern Colorado that together represent roughly 1.1 gigawatts of nameplate capacity. Both projects were substantially complete by late 2023, but PSCo discovered it lacked a continuous easement across a single parcel to connect the generator lead lines to its transmission system. The utility negotiated with the landowner for months before filing for eminent domain in early 2024, seeking a permanent easement roughly 550 feet long and 30 feet wide – approximately 0.38 acres – plus temporary construction access.
In June 2024, a Morgan County district court judge denied PSCo’s petition, ruling the utility failed to prove the taking was “necessary” under Colorado’s eminent domain statute. The court found PSCo had not adequately explored alternative routes, even though the utility testified that rerouting would require crossing additional parcels, adding months of delay and millions in cost. PSCo’s appeal to the Colorado Supreme Court, filed in August, argues the lower court imposed a de facto “exhaust all alternatives” standard that exceeds statutory requirements and effectively gives any single landowner veto power over interconnection of utility-scale renewable projects.
Colorado law permits utilities to exercise eminent domain for “transmission lines” and “substations” when the taking serves a public use. The statute does not explicitly define the scope of “necessity,” leaving courts to interpret whether a utility must prove no other feasible route exists or merely that the chosen route is reasonable. PSCo’s brief cites a 2019 Colorado Court of Appeals decision, City of Thornton v. Bijou Irrigation Co., which held that necessity does not require absolute indispensability. The landowner’s counsel counters that wind generation is intermittent and that PSCo’s ratepayer benefit argument conflates corporate profit with public necessity.
National Transmission Bottlenecks Magnify Stakes of Single-Parcel Disputes
That points to a structural mismatch: the U.S. adds roughly 20-25 gigawatts of wind and solar annually, but new transmission miles have averaged under 1,000 per year over the past decade – far below the 2-3 times expansion the National Renewable Energy Laboratory estimates is needed by 2035 to meet decarbonization targets. Interconnection queues now hold over 2,600 gigawatts of generation and storage nationwide, with typical wait times exceeding four years. Most queue delays stem from transmission upgrade studies, not final easement acquisition. But as developers exhaust “easy” interconnection points on existing corridors, the final mile – often crossing private land – becomes a disproportionate choke point.
By comparison, Texas and the Midwest have seen similar disputes where a single holdout parcel delayed hundreds of megawatts. In 2022, a Kansas court upheld eminent domain for a 345-kilovolt line serving wind farms, emphasizing the statutory definition of public use included renewable integration. Colorado’s constitution, however, contains a “private property” clause (Article II, Section 15) that has been interpreted more protectively than the federal Fifth Amendment. If the Supreme Court affirms the district court, utilities may need to secure every easement before construction begins – adding 12-18 months to project timelines and increasing development risk premiums. That would raise the levelized cost of energy for Colorado wind by an estimated $2-4 per megawatt-hour, based on typical carrying cost assumptions for delayed commercial operation.
PSCo’s ratepayer harm argument rests on two concrete figures: the loss of federal production tax credits (PTCs) valued at roughly $27.50 per megawatt-hour for the first ten years of operation, and the cost of replacement power – likely gas-fired generation or market purchases – during the delay. A 1.1-gigawatt wind portfolio operating at a 45% capacity factor generates approximately 4.3 terawatt-hours annually. At current PTC rates, each month of delay forfeits roughly $10-12 million in tax credits that would otherwise flow to customers through rate base adjustments. Replacement power at $50-80 per megawatt-hour adds another $1.5-2.5 million monthly. These are not speculative; they appear in PSCo’s regulatory filings for its Electric Resource Plan.
Who This Affects
- Utility planners: Must now budget for pre-construction easement acquisition on every interconnection segment, not just trunk-line corridors, adding 6-12 months to permitting schedules and requiring earlier landowner engagement.
- Wind and solar developers: Face heightened risk that interconnection agreements with utilities do not guarantee delivery if the utility cannot secure final easements; contracts should specify risk allocation for eminent domain delays.
- State policymakers: May need to clarify eminent domain statutes to define “necessity” for renewable interconnection, or create a streamlined administrative process for minimal-impact easements below a defined acreage threshold.
- Transmission investors: Should factor legal risk premiums into return models for merchant transmission and generation-tie lines in states with protective property-rights jurisprudence.
What to Watch Next
- Colorado Supreme Court docketing and oral argument schedule: The court has discretion to deny review; if accepted, a ruling would likely arrive mid-2025, creating a binding precedent for all Colorado utilities.
- PSCo’s next Electric Resource Plan filing (expected 2025): Will reveal whether the utility adjusts its wind and solar procurement targets or accelerates gas capacity to hedge against interconnection uncertainty.
- Legislative response in the 2025 Colorado General Assembly: Bills to amend eminent domain standards for clean energy infrastructure have been drafted in prior sessions; this case may catalyze action.
- FERC Order 1920 implementation in the West: Regional transmission planning reforms could reduce reliance on single-parcel generator-tie lines by expanding shared network upgrades, but only if state siting authority cooperates.
Bottom line: A 550-foot easement dispute has become a proxy battle for whether the legal framework governing 20th-century transmission can accommodate the granular, distributed land needs of a 21st-century renewable grid – and the Colorado Supreme Court’s answer will ripple through every utility’s interconnection playbook.
