NuScale’s Next PPA Deadline May Decide Whether Investors Stay

NuScale Power’s most important number may not appear in its next earnings release. It is 6 gigawatts, the proposed size of a small-modular-reactor program involving the Tennessee Valley Authority and project developer ENTRA1 Energy.

The project is still only a non-binding arrangement. The decisive step is a power purchase agreement, or PPA, that would commit TVA to buying electricity from the planned reactors. NuScale’s chief financial officer has targeted the end of 2026 for that agreement. If the deadline passes without a signed contract, investors would have a much clearer reason to question whether the company’s customer pipeline can become a commercial business.

That distinction matters because NuScale has already cleared one of the industry’s biggest technical hurdles. Its 77-megawatt NuScale Power Module holds U.S. Nuclear Regulatory Commission design certification, and the company says it has more than 60 specialized supply-chain partners. The remaining problem is not simply whether the reactor can be licensed. It is whether a utility will commit capital and accept long-term power obligations.

A signed PPA would do more than create a customer. It would give lenders, suppliers and potential project partners a contractual basis for financing and construction. It would also test whether NuScale and ENTRA1 can convert an attractive memorandum into revenue-generating infrastructure.

The balance sheet gives NuScale time, but not proof of demand. The company ended the second quarter with $1.9 billion in cash, cash equivalents and investments, yet quarterly revenue fell to $75,000 after Fluor’s engineering work for the Romanian RoPower project was completed. NuScale also posted a $50.1 million net loss for the period.

There is another wrinkle. Under NuScale’s 2025 agreement with ENTRA1, ENTRA1 retains discretion over which projects it pursues and whether it contracts with NuScale. The partnership therefore does not guarantee an order, even though NuScale is designated as the key supplier for future ENTRA1 projects.

For shareholders, the PPA is a binary commercial test. Signing one could shift SMR from speculative reactor developer toward financed infrastructure supplier. Failure to sign would leave the company well funded, technically advanced and still waiting for its first major deployment to move beyond promises.
