Ulysses AEP capacity and PJM market access

Checked on September 16, 2026. The cited source supports part of this claim, but not all of it.

The filing confirms the AEP Ohio capacity and the PJM description, but frames PJM access as something the site will provide once energized, not something already in place.

Confirmed in the source:

• The Ulysses acquisition secured capacity from AEP Ohio to support development of the site
• Once energized, the Ulysses Site will provide Cipher with direct access to PJM Interconnection L.L.C.
• PJM Interconnection L.L.C. is described as the largest wholesale electricity market in the United States

We could not confirm this from the cited source:

• That the Ulysses Site currently provides direct access to PJM, rather than being expected to do so only after energization

That does not mean it is false — only that this source does not establish it, as of the date above. If we find a source that settles it, we will re-check and update this page.
