As of 14 Oct 2026
IHI Terrasun designs, integrates, controls and services battery energy storage projects for solar and energy storage developers in North America.
This map covers the kinds of organizations that develop, own and run those projects, how many of them there are where a clean public count exists, and who usually signs off on design, integration, controls and field service at each.
Organizations that develop, own or operate solar and battery storage plants in the United States. A group without a clean public code says so rather than showing a number.
| Group | Organizations in the US | Under 20 staff | 20 to 99 | 100 to 499 | 500 or more |
|---|---|---|---|---|---|
| Solar and energy storage project developers | no clean public count | ||||
| Solar power plant owners and operators | about 530 | not published | not published | not published | not published |
| Owners of other generation, including standalone battery storage plants | about 92 | not published | not published | not published | not published |
| Electric distribution utilities and cooperatives | about 1,300 | about 440 | about 560 | about 200 | about 80 |
| Engineering, procurement and construction contractors that build solar and storage plants | no clean public count | ||||
| Asset managers and infrastructure owners holding operating storage portfolios | no clean public count |
US firm counts by industry code, banded deliberately.
Titles vary by organization. These are the roles that usually own the decision for each kind of work IHI Terrasun sells.
| Group | Usually signs off | What they decide |
|---|---|---|
| Project developers | VP of Engineering, Director of Energy Storage, VP of Development | Battery and inverter selection, front-end design, who integrates and commissions |
| Solar plant owners and operators | Director of Asset Management, VP of Operations | Adding storage to existing solar sites, plant controls, long-term service |
| Owners of standalone storage plants | Head of Energy Storage, Director of Operations | Controls, monitoring, preventive and corrective maintenance after commercial operation |
| Distribution utilities and cooperatives | Director of Grid Modernization, Manager of Distributed Energy Resources | Utility-owned storage, grid compliance, service contracts |
| Engineering and construction contractors | Director of Procurement, Project Director | Integration and commissioning partners on a given build |
| Asset managers and infrastructure owners | Asset Manager, VP of Asset Management | Warranty handling, field service coverage, performance reporting |
Design and equipment choices are made early, before a developer commits to a battery or inverter maker. The engineering lead and the development lead usually decide together, and procurement follows.
Integration, commissioning and controls are bought as a project moves toward energization, often with the construction contractor at the table.
Field service, monitoring and warranty support are bought after commercial operation, by the operations or asset management team that has to keep the plant available.
Owners running plants built on more than one battery or inverter maker need one team that can troubleshoot across all of them and coordinate warranty claims. That is the gap IHI Terrasun describes on its own site, and it is a question every owner of a mixed fleet already has to answer.
