Tenaska is planning a new 1.7 GW natural gas power plant in Saline Township, Ohio. The project is part of the Tri-State Energy Hub and aims to integrate large-scale power generation with carbon capture and storage technology. The company has already submitted requests for 30 carbon dioxide injection wells to support the CCS infrastructure. This expansion highlights the industry's push to combine traditional gas power with sequestration to reduce net emissions.

1.7 GW is a massive addition to the local grid. I wonder what the interconnection timeline looks like for a project this size in Ohio. Does the current transmission infrastructure actually support this much new capacity without major upgrades?

The real question is the 45Q tax credit. This whole project likely hinges on those sequestration payments. Without the federal subsidy for carbon capture, building a new gas plant of this scale is a hard sell in the current regulatory environment.

Basically Tenaska wants to build a giant gas plant but is leaning on a CCS hub to make it palatable. They mentioned 30 injection wells, but we have not seen the actual capture efficiency rates they are targeting yet.

Capture efficiency is one thing, but the energy penalty for running CCS is huge. They will have to burn more gas just to power the equipment that captures the carbon. That parasitic load usually eats a big chunk of the nameplate capacity.
