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.
CLEAN ENERGY & GRID INFRASTRUCTURE
The energy transition,
engineered to last.
From generation and transmission to storage and data, MERIDIAN designs and operates the power infrastructure that society runs on — making the shift to renewable energy real.

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