01 BUSINESS

What we do

Generation, transmission, storage, and data. We support the entire energy value chain — in one company.

01

Renewable Generation

Solar & Wind

Centred on solar and onshore/offshore wind, we handle power plants end to end — development, design, EPC and O&M — from site assessment to decades of stable output.

02

Smart Grid

Next-gen Transmission

We unify distributed generation and optimise supply and demand. Digital control and protection systems deliver a resilient, flexible power network.

03

Storage & Control

Battery Systems

Grid-scale batteries and fast control software stabilise frequency regulation and supply-demand balance — turning variable renewables into dependable power.

04

Data Platform

Analytics & Forecasting

We operate a cloud platform that collects and analyses operating data across every asset — advancing everything from generation forecasting to demand response.
