Utility-Scale Power Infrastructure, Engineered and Built End to End
Full-scope EPC and self-perform construction from the first cable pull through energization, covering generation, collection, substation, transmission, storage, and controls.
From the first survey stake to final energization, Althea Power builds the infrastructure that brings clean energy onto the grid. We self-perform electrical scopes from low voltage through high voltage, which means fewer handoffs, tighter schedules, and a single team accountable for every connection between the generation source and the point of interconnection.
Whether the project is a utility-scale solar array, a standalone storage facility, or the substation and transmission line that ties it all together, we build it to perform for decades.

One Team, Start to Finish
Our strength is integration. Because we build every layer of the project, from DC wiring to high voltage and controls, we see how each scope affects the next and plan accordingly.
The result is a smoother path to commercial operation, a cleaner turnover package, and infrastructure our clients can rely on.
How We Build
- Self-perform electrical capabilities across low, medium, and high voltage scopes
- Engineering coordination with the engineer of record and utility interconnection teams
- QA/QC programs, inspection and test plans (ITPs), and complete turnover documentation
- Commissioning through COD, including utility witness testing
- Safety: OSHA 10/30 trained crews and NFPA 70E compliance
