Denver International Airport Explores Broader Clean Energy Alternatives
As Denver International Airport pivots from its previous plan to explore nuclear energy, it is now seeking a wide array of clean energy solutions to meet escalating power demands. The airport, a key economic player and the sixth busiest globally, has initiated a call for information from private entities to suggest innovative ways to integrate electricity generation and storage with its current energy framework.
On December 29, the airport released an invitation for proposals, aiming to discover the best strategies to support its expansion and achieve net-zero climate impact by 2040. “We were flexible in this regard, going to a broader perspective on clean energy,” said airport CEO Phil Washington in a conversation with Denverite. “It was a lesson for us. We did not do it right the first time, and we went back and corrected that.”
The shift in strategy comes after public pushback against an earlier initiative to study modular nuclear reactors. Originally announced in August by Washington and Mayor Mike Johnston, the $1.25 million study sought to investigate the feasibility of a small modular reactor at the airport. The proposal, however, faced criticism over potential safety and environmental concerns, prompting the airport to retract the plan for broader community input.
Why the Demand for Power?
Global airports, including DIA, anticipate a surge in electricity needs as transportation systems transition from fossil fuels to electric power. DIA’s expansion plans, which include new gates and a rental car facility, project an increase from 83 million passengers in 2025 to 120 million annually by 2045, potentially tripling its peak power demand by 2040.
With the possibility of airlines adopting all-electric aircraft and exploring electric heating systems, the airport’s peak power demand could rise to 400 megawatts by 2045, compared to Colorado Springs’ current peak of about 1,000 megawatts. An onsite power plant could also mitigate risks of blackouts, as seen in the 2025 London Heathrow substation fire that led to numerous flight cancellations.
Beyond Meeting Own Needs
DIA’s ambitions may extend beyond self-sufficiency. The airport, which spans 53 acres, is considering selling excess electricity to nearby customers, potentially operating like a utility company. This prospect is fueled by plans to lease land for private development, possibly attracting energy-intensive data centers.
Denver City Councilperson Stacie Gilmore, representing the airport’s district, believes the focus on new power sources aligns with development ambitions. She points to previous energy supply challenges, such as Swire Coca-Cola’s decision to halt a project over power concerns, as driving factors in DIA’s energy pursuits.
While Gilmore questions why the airport doesn’t partner with Xcel Energy for regional benefits, Washington maintains the focus is on ensuring energy redundancy for DIA as a vital state revenue source. Xcel Colorado, meanwhile, affirms its commitment to supporting the airport’s energy requirements now and in the future.
