The Local Energy Supply Guides from Ynni Cymru are available in English and Welsh and provide practical, accessible information to help organisations explore local energy supply opportunities and make better use of locally generated renewable energy. The guidance covers the key regulatory, commercial and technical considerations involved in developing local energy supply projects, helping organisations understand the options available and assess potential approaches.
The guides cover Behind-the-Meter Energy Systems, Private Wire Energy Systems and Licence Exempt Electricity Supply. They explain how each model works, the opportunities it may offer, and the factors organisations should consider before progressing a project. The guidance is designed for local authorities, public sector organisations, SMEs, voluntary and charitable organisations, community energy organisations, renewable energy developers and others interested in retaining more value from renewable energy within local communities.
Ynni Cymru (a Welsh Government programme) hosted a webinar to provide an overview of its proposed capital grant scheme for Smart Local Energy System (SLES) projects.
The scheme is intended to support organisations in Wales, including the public sector, voluntary, community and social enterprise sectors, and small and medium-sized enterprises (SMEs).
SLES projects are expected to combine renewable energy generation technologies with data and control systems and energy storage to support energy needs such as operational power, heating or transport.
This webinar recording provides an overview of the proposed scheme, including key information on eligibility and the anticipated application process.
Drop in sessions
Our Ynni Cymru grant drop-in sessions are informal online meetings where applicants can join to ask questions about the fund and the application process. Ynni Cymru colleagues will be available for an hour to provide guidance, clarify eligibility or application requirements, and help you better understand what the grant can support.
The Wales Annual Impact Report 2025 showcases the successes we have helped our clients in Wales achieve across renewable energy, waste management, housing, infrastructure, procurement and more.
It demonstrates how we enhance and strengthen public services by turning Welsh Government priorities and policy into action. The report illustrates the value and efficacy we have delivered for Welsh communities.
Energy Performance Contracting (EPC – formerly Re:fit) case studies.
In the face of the climate emergency and tightening fiscal constraints, public bodies must find smarter, faster routes to decarbonisation and energy resilience. The EPC (formerly Re:fit) framework provides exactly that: a proven delivery mechanism for energy efficiency, low-carbon retrofit and renewable generation projects in the public sector. Below we bring together a curated set of case studies that illustrate how councils, universities, NHS trusts and other public institutions are using EPC / Re:fit to drive real savings, reduce carbon emissions and modernise infrastructure.
Each case study captures a journey — the baseline challenges, the technical interventions, the financing approach, and the measurable outcomes. Taken together, they tell a story of how the EPC / Re:fit route is enabling scalable, credible progress toward net zero across diverse geographies and building portfolios.
As the energy landscape evolves, battery energy storage is emerging as a key solution for organisations looking to enhance their energy efficiency, reduce costs and participate in new revenue opportunities.
Ynni Cymru has developed a new Wales Energy Storage Tool designed specifically to help Wales to explore the feasibility of installing a Battery Energy Storage System (BESS).
This innovative tool allows users to assess whether battery storage makes financial sense for their site, estimate the potential return on investment and understand how much revenue they could earn from participating in key energy market streams. Whether you already have renewable generation or are planning new installations, this tool can provide the insights you need to make informed decisions about integrating battery storage into your energy plans.
Our Impact Report 2024-25 is here
We are proud to share our Impact Report 2024-25 – a reflection of another remarkable year at Local Partnerships. This report captures the breadth and depth of our work, and the tangible difference we’ve made across England and Wales.
As a publicly owned, in-house delivery partner, our role has never been more vital. Against a backdrop of financial constraint, climate urgency, and systemic reform, we’ve continued to bring clarity, capability, and confidence to the public sector. Our teams have delivered measurable impact – whether by supporting climate resilience, helping councils transform, unlocking infrastructure opportunities, or enabling local leaders to improve lives in their communities.
This year’s report illustrates how deeply embedded we are in the real-world challenges our partners face – and how we consistently help them rise to meet them. It also celebrates the growing strength of our partnerships across central government, the LGA, the devolved administrations, and local authorities.
We invite you to explore how we’ve made a difference – and how we’re helping shape a better future, together.
Setting up simple renewable energy export agreements: Smart Export Guarantee (SEG) and Utility Power Purchase Agreement (PPA)
Energy export agreements can help you unlock revenue from surplus renewable electricity.
If you have renewable electricity generating assets supplying your building or site, there may be times when you are generating more electricity than you are using. If you have an export agreement in place (such as SEG or a Utility PPA) you will be compensated for each unit of electricity you send to the grid. If you don’t have this in place, it could be costing you ££££s per year in lost revenue. This webinar from Ynni Cymru arms you with the information you need to receive optimal payment for electricity exported.
The Local Authority Transformation in Wales webinar will cover high level do’s and don’ts for transformation activity.
Everything from how to get started (including capacity and maturity of your organisation), how to course correct and how to manage benefits realisation and more.
