The GwyrddNi movement is rooted in empowering communities across Gwynedd to take meaningful, local action against climate change. Central to this vision is the drive toward community-owned renewable energy projects and improved energy efficiency. The goal is to build stronger community resilience while reducing reliance on fossil fuels.
Energy was one of the key themes identified across all five areas of the GwyrddNi Community Climate Action Plans. Through the Community Assemblies held between 2022 and 2023, local residents developed shared visions for a healthier, fairer, and greener future, which consistently highlighted the need for local control over energy resources.
What the Communities Want
Residents involved in the Assemblies were clear that energy projects should reduce the community’s dependence on oil and gas, offer protection from sudden price spikes, and ensure that financial benefits are reinvested locally.
Specific energy ideas that emerged from the community-led Action Plans include:
• Dyffryn Ogwen residents aimed for an “Off Grid Community Energy” system, aspiring to be a self-sufficient valley meeting its own energy needs, potentially through a micro-grid. This idea is inspired by existing community projects like the Ynni Ogwen Cyf hydro scheme, a 100KW scheme owned by the community.
• Dyffryn Nantlle prioritised Community Energy, planning research to map resources and potential generation sites to develop renewable energy for local use and benefit. This work must be linked directly to projects focused on reducing energy consumption in homes.
• In Bro Ffestiniog, participants emphasized the need to understand existing efforts, such as the work surrounding the Llechwedd Hydro scheme, and wished to map out all current renewable energy across the area.
• Dyffryn Peris committed to researching the feasibility of developing various sources, including a hydro turbine on a suitable river, urban/rural solar farms, and small wind turbines, noting the importance of connecting with local energy research groups like Ynni Padarn Peris.
• Pen Llŷn sought to establish a Community Energy Agency/Information Hub in cooperation with local partner Ynni Llŷn, which would support and promote local home energy efficiency and green energy production.
Current Project: Ynni Lleu

Ynni Lleu has been re-established as a community benefit company, with 10 new members (including 7 new directors) joining to take over and lead the group. Siôn, Dyffryn Nantlle’s Community Facilitator, joined the board and took on the role of Secretary to help the group move forward.
Ynni Lleu is currently undertaking the installation of a large-scale solar and battery scheme located on the roof of the old paper factory at the Penygroes industrial estate, with funding from Ynni Cymru, and support from DEG and Cyd Ynni.
The project involves installing 311 kW of solar panels, a battery with storage capacity of 307 kWh, with an expected annual output of renewable electricity is 311,000 kWh.
The panels should provide over 60% of the annual electricity requirements for the tenants on the site, which include Adra, Tŷ Gwyrddfai, Travis Perkins, and Pero, and generate an estimated income of £25,000 annually for Ynni Lleu to reinvest into community projects.
