Turning insights into action

Data-driven Operations & Maintenance solutions for large-scale renewable energy assets.

Company

The world has built the capacity. Now it has to perform.

A decade of investment has put renewable energy on the grid at scale. Far less attention has gone to what happens afterwards. Actum exists for the second question — not how much was built, but how much of it actually arrives, every day it operates.

Solutions

We close the distance between knowing and doing.

We establish what an asset should have produced under the conditions it actually faced, and we pursue the difference until it is found, assigned, corrected and confirmed. Monitoring tells an owner that something is wrong. Our work begins at that point.

What we do

Clients

The owners and builders of the transition.

Asset owners, independent power producers, developers, funds and EPCs — across solar PV, wind, battery storage and hydro. From a single asset to portfolios spread across countries, contractors and standards, we give them one view of the whole, held to one discipline.

Careers

Bring what you know.

We are growing, and we are looking for bright minds who want to make renewable energy assets perform better. People who know the industry’s challenges from the inside — in solar, wind, battery storage or hydro; in operations, monitoring, performance analysis or digital O&M — and want to solve them with the best of modern software and AI.
