Electricity demand is surging, rates are rising, and America’s grid is struggling to keep up. In the long-run, we’ll need substantial investments in new power plants and transmission lines, but those facilities take years—sometimes more than a decade—to build. Adding capacity quickly will require getting more out of the infrastructure we already have. Council analysis identified over 500 GW of power that we can bring on-line through relatively modest, near-term investments. And now, we’re seeing capital start to move.
This analysis unpacks roughly $16.75 billion in public and private investments and how they’re shaping two priorities central to building a secure, reliable, and affordable power sector: improving grid efficiency and scaling clean firm power.
SPARK pairs public and private funding to optimize existing lines
In September, DOE’s Office of Electricity announced $1.9 billion for 31 grid-improvement projects through the Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades (SPARK) Initiative, linked to an additional $3.35 billion in private sector cost share commitments. These investments will deploy some of the fastest and most cost-effective technologies to expand capacity, ease congestion, and lower prices. The portfolio includes nine projects to reconductor or rebuild more than 1,500 miles of transmission lines, 18 projects to deploy grid-enhancing technologies (GETs) for real-time monitoring and power flow control over 21,000 line miles, and four interregional projects to serve new large loads, unlocking over 23 GW of capacity.
The private sector cost sharing is perhaps SPARK’s most significant impact. Under cost-of-service regulation, utilities earn returns on capital spending, which favors new builds over upgrades that squeeze more out of existing lines. Programs like SPARK demonstrate how federal funds can effectively mobilize private investment and unlock low-cost capacity that helps keep costs down for ratepayers.
DOE and hyperscalers are supporting clean firm power through nuclear uprates
DOE and the private sector are also spurring investment into maintaining and uprating existing nuclear power plants. Nuclear plants are our largest form of clean firm power: low-emissions electricity available around-the-clock. Uprates allow operators to get more power out of the same facilities to add capacity quickly and at relatively low cost.
On October 5, DOE’s Office of Energy Dominance Financing (EDF) announced a conditional loan commitment of up to $4.2 billion to uprate three of Vistra’s nuclear facilities, adding 433 MW of new capacity while also preserving 4GW of existing nuclear generation and including options to finance future uprates.
Hyperscalers are financing uprates, too. Amazon and Google recently signed 20-year power purchase agreements (PPAs) with Constellation, backing $7.3 billion in investments that will enable Constellation to add 1,080 MW to its nuclear fleet.
The two models work differently: DOE will lend Vistra up to $4.2 billion once it meets the agency’s conditions, allowing Vistra to cover large, up-front costs; the hyperscaler PPAs are promises to buy power over 20 years, giving Constellation the revenue certainty to finance the uprates itself. Both models help plant owners maintain and expand their fleets, support lower emissions, and strengthen grid reliability in shorter timelines.
Conclusion
The U.S. government, utilities, and hyperscalers are working together to unlock the U.S. energy system and unleash new capacity quickly and affordably. Programs like SPARK can use public funding to draw in private cost share, conditional loan commitments can pencil out big deals quickly, and long-term contracts from major load centers can give plant operators certainty to expand clean firm capacity.
Upgrades like these are vital but are not a complete solution. Rising demand will still require new generation and transmission lines, and with them, broader reforms to permitting and utility incentives. But they are an essential first step in a phased approach that adds power and lowers costs now while longer-term projects get underway.
