Line to Load.
Althea Power is a self-perform electrical contractor. We build the power systems that energize critical infrastructure, from the point of interconnection to the load: substations, transmission and gen-ties, medium-voltage distribution, battery energy storage, utility-scale generation, and power for data centers and industrial facilities.
The full power delivery chain.
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.
- 480 V to 500 kV Self-perform range
- 29.43 GWdc Combined team experience
- 35 Substations, up to 500 kV
- 246 Projects built by our team
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.
-
DC to 35 kV
Generate
Utility-scale solar, wind and battery storage. DC collection through the point of interconnection.

Up to 230 kV
Transmit
Overhead and underground transmission. New lines, rebuilds, relocations and interconnections.
-
Up to 500 kV
Transform
Turnkey distribution and transmission substations, including work in energized yards.
-
5–35 kV
Distribute
Campus, industrial and site distribution. Underground and overhead, tested through energization.
-
480 V
Deliver
Mission-critical and commercial facilities, from the service entrance to the white space.
What we build
We self-perform electrical work from 480 V to 500 kV, from the point of interconnection to the load.
-

Substations
Collector and interconnection substations up to 500 kV, built, tested and energized together with the utility.
View scope -

Transmission lines
Gen-tie and transmission lines up to 230 kV that carry power to the point of interconnection.
View scope -

Medium-voltage collection
Collection and distribution systems trenched, terminated and tested for the plant's operating life.
View scope -

Site electrical
AC and DC systems, grounding and raceway, installed and verified before the project moves to the next phase.
View scope -

Battery energy storage
Code-compliant battery storage facilities, commissioned and ready to dispatch.
View scope -

Solar and wind electrical
Electrical installation for solar, wind and hybrid generation, wired and tested to protect the energy model.
View scope -

Protection and controls
Relay and control panels, wired, tested and commissioned, so faults clear fast and the right breaker opens.
View scope -

Fiber and communications
Fiber backbone and plant communications, installed, spliced, terminated and tested, so controls and SCADA have a network they can rely on.
View scope -

Mechanical installation
Racking, trackers and modules installed to drawings and torque specs, and major equipment set, anchored and ready for termination.
View scope
Markets
The same crews and controls across scopes that would otherwise be split.
-
High-voltage
Turnkey distribution and transmission substations, new build and expansion.
-
Transmission
Overhead and underground HV lines and gen-ties to the point of interconnection, up to 230 kV.
-
Mission critical
Power distribution for data centers and industrial facilities.
-
Battery storage
Utility-scale battery energy storage, from the enclosures to the point of interconnection.
-
Solar PV
Utility-scale solar, from DC collection to the point of interconnection.
-
Wind
Collection and interconnection electrical for utility-scale wind.
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.
Built by people who've built it.
Our team brings 246 projects and 29.43 GWdc of combined electrical construction experience across 24 states and two Canadian provinces, on one delivery standard: LAUNCH, LIVE and LANDED.
