Who are we?
Ynni Ystradau is a Community Energy Services Company (CESCo) established by Cwmni Bro Ffestiniog in partnership with Energy Local in order to tackle fuel poverty in Tanygrisiau.
We believe that everyone deserves a warm home and affordable heat.
We are on a mission to insulate houses in Tanygrisiau, reducing the amount of energy needed to heat a home. Alongside this we are establishing a community owned heat network powered by locally generated electricity.
What is a CESCo?
A Community Energy Services Company (CESCo) is a not-for-profit company (a Community Benefit Society,or CBS in our case) which is owned and run by the community, for the benefit of the community.
Ynni Ystradau is a CESCo that will own, maintain, and operate a heat network for Tanygrisiau. Any profits generated by the CESCo will be reinvested back into the community -helping to maintain and improve the system, or supporting other priorities chosen by our members — rather than going to private shareholders.
Who we work with...
While we are firmly grounded in the community, we have strong support for our work across all sectors. We work closely with Gwynedd Council and the Welsh Government, alongside local housing associations, utility providers, and two major employers based here in the village.
Tanygrisiau is an UNESCO World Heritage Site, and our work is shaped by that history. In many ways, we’re going back to our roots, building on a slate industry legacy that stretches back to the 1800s, while looking ahead to a more sustainable future. As part of this, we’re proud to source our energy from a local hydro scheme at Llechwedd, operated by J.W. Greaves, linking our mining past to a greener future.
This same approach carries through into how we deliver our projects. Wherever possible, we work with local suppliers and contractors, and we’re committed to helping upskill the local workforce so the benefits of this work stay within the community for the long term.
