Natural Gas Seen as Critical Stopgap for Washington State’s Growing Energy Shortfall
Why It Matters
Washington State and the broader Pacific Northwest are facing a looming electricity shortfall that could affect the reliability and affordability of power for millions of residents. A new regional analysis warns that demand is outpacing the pace of new energy construction — and that without natural gas as a bridge resource, the region risks rotating blackouts during periods of peak stress.
The findings carry direct implications for Washington’s energy policy, where state government has placed heavy emphasis on decarbonization goals while simultaneously driving up electricity demand through electrification mandates for vehicles and home heating.
What Happened
Energy and Environmental Economics, a San Francisco-based consulting firm, released a regional analysis identifying a near-term electricity supply crunch across the Pacific Northwest. Senior partner Arne Olson presented the findings and discussed the results in an interview on TVW’s Inside Olympia with host Austin Jenkins.
Olson said the region is experiencing pressure from both directions simultaneously: supply has been constrained by coal plant retirements, slow permitting, transmission bottlenecks, and supply chain disruptions, while demand is accelerating sharply. The primary driver of new demand, he said, is the rapid expansion of artificial intelligence-powered data centers from the technology industry.
“We see a looming shortfall of electric power with the need to construct a significant amount of new resources to fill that gap,” Olson said. “The need is now. It’s not 10 years from now.”
Olson argued that while wind, solar, and battery storage must be part of the solution, natural gas remains essential to ensuring reliability — particularly during cold winter conditions when hydroelectric output is low. “You’ll be very happy that you have a natural gas plant during that circumstance that you can turn on rather than having to endure a rotating blackout type of an event,” he said.
By the Numbers
- Roughly 60% to 65% of the Pacific Northwest’s electricity supply comes from hydroelectric generation, which varies with water conditions.
- The analysis identifies artificial intelligence and data centers as the primary driver of what Olson called “an unprecedented amount of new electric demand.”
- Washington’s Climate Commitment Act does not prohibit natural gas but regulates its emissions within a declining carbon cap, increasing the fuel’s cost over time.
- Environmental groups including the Sierra Club, Natural Resources Defense Council, and Climate Solutions have all called for a limited or transitional role for natural gas — with the Sierra Club now opposing new gas infrastructure entirely.
Zoom Out
The Pacific Northwest’s energy crunch reflects a broader tension playing out across the Mountain West and nationally: aggressive government-driven electrification policies are increasing electricity demand faster than the grid can accommodate new generation. States like Washington have committed to deep emissions reductions while simultaneously mandating electric vehicles and phasing out natural gas in homes — policies that together put enormous strain on a grid already constrained by permitting backlogs and supply chain disruptions.
Washington’s heavy reliance on hydropower, long seen as a regional strength, is now also a vulnerability. Olson warned that a prolonged cold snap paired with low water conditions presents the highest near-term risk of shortages — a scenario that no amount of wind or solar capacity alone can fully address given current battery storage limitations.
The state’s broader fiscal pressures — including budget cuts that have forced the closure of state campgrounds and the politically contentious passage of a new millionaires tax — suggest that the cost increases Olson flagged as inevitable will land on taxpayers and ratepayers already facing a tightening financial environment.
Nuclear energy, long-duration storage, geothermal, and carbon capture all show promise as longer-term solutions, Olson said, but none are expected to scale quickly enough to address the near-term shortfall.
What’s Next
Olson said utilities and policymakers must move quickly to develop wind, solar, battery, and demand-flexibility resources while also maintaining and potentially expanding natural gas capacity as a reliability backstop. Over time, he said, gas plants would be used less frequently as cleaner resources come online — but the transition will come with higher costs as utilities invest in new infrastructure.
Washington’s Climate Commitment Act will continue to increase the cost of natural gas through its carbon allowance market, even as the fuel remains a legally permitted part of the state’s energy mix. Environmental groups are expected to continue pressing utilities and state regulators to commit to clean energy timelines and reject new gas infrastructure approvals.
