ABOUT GREEN GEN CYMRU POWERING A POSITIVE ENERGY FUTURE FOR WALES

At Green Gen Cymru, we’re acting now to build and operate a green energy network for Wales, that will make sure 100% renewable energy can flow to our homes, hospitals, schools, businesses, and communities.

We’re playing a pivotal role in providing a reliable and robust distribution network that will tackle the energy crisis, climate crisis, as well as the cost‑of‑living crisis. It will also empower rural communities through investment, jobs, and skills, enabling communities to live modern electric lives.

We want to make sure Wales has the energy it needs in a Net Zero world.

There’s endless potential for renewable energy in Wales – particularly from the wind that blows across our hills and mountains. But the green energy is stuck in the windy areas of Wales, and we need to get it to the homes, hospitals, schools, businesses, and communities that need it. To response to this challenge and meet Welsh Government’s target for 100% renewable electricity in Wales by 2035, we’re developing a stronger, more resilient renewable electricity network that is greatly needed in Wales – distributing clean, green energy.

We want to build a positive, clean future for us all.

Salary: Starting from £75,000 per annum (skills and experience dependent)
