Every voltage. Every phase.

Althea Power is a specialty electrical contractor working across the full power delivery chain — from renewable generation and high-voltage transmission, through substations and medium-voltage distribution, to the commercial and mission-critical facilities at the end of the line.

That range is deliberate. The same crews, testing discipline, and project controls that energize a 230 kV substation carry into a campus MV loop or a commercial service entrance. It lets us serve utilities, IPPs, renewable developers, EPCs, general contractors, and building owners from one organization, and it lets clients keep a single contractor across scopes that would otherwise be split.

Our work is self-performed by licensed journeymen and qualified electrical workers, with in-house project management, estimating, and commissioning support, under a documented safety program built around OSHA 1910.269, NFPA 70E, and client site requirements.

One contractor, the whole way down the line.

Power is generated, carried, stepped down, distributed and delivered. Althea Power self-performs the electrical work at every one of those stages, so the schedule-critical path stays with one crew and one set of controls.

  1. DC to 35 kV

    Generate

    Utility-scale solar, wind and battery storage. DC collection through the point of interconnection.

  2. 69–500 kV

    Transmit

    Overhead and underground transmission. New lines, rebuilds, relocations and interconnections.

  3. to 230 kV+

    Transform

    Turnkey distribution and transmission substations, including work in energized yards.

  4. 5–35 kV

    Distribute

    Campus, industrial and site distribution. Underground and overhead, tested through energization.

  5. 480 V

    Deliver

    Mission-critical and commercial facilities, from the service entrance to the white space.

What we build

Balance-of-plant electrical, self-performed from DC collection to the point of interconnection.

What we maintain

The crews that build the systems are the crews that keep them running.

Testing, preventive maintenance and emergency response across six kinds of infrastructure, where the maintenance window is the constraint and an unplanned trip is the failure condition.

Markets

Six markets, one contractor. The same crews and controls across scopes that would otherwise be split.

  1. Renewable Energy & Storage

    Utility-scale solar PV, wind, and battery energy storage.

  2. High Voltage Transmission

    Overhead and underground transmission, 69 kV through 500 kV.

  3. Substations

    Turnkey distribution and transmission substations, new build and expansion.

  4. Medium Voltage Distribution

    5 kV–35 kV systems, underground and overhead.

  5. Data Centers

    Mission-critical electrical construction for hyperscale, colocation, and enterprise facilities.

  6. Commercial Construction

    Ground-up, expansion, and renovation work for commercial, institutional, and industrial buildings.

How the work gets done.

Self-performed
Licensed journeymen and qualified electrical workers on our own payroll. The scopes that decide the schedule are not subcontracted.
In-house controls
Project management, estimating and commissioning support from the same organization that fields the crews.
Documented safety
A written program built around OSHA 1910.269, NFPA 70E and each client's site requirements.
Outage discipline
Switching coordination, clearance management and compressed-window execution, planned early and held to daily.
