We’re delighted to see Kilmarnock South Battery energy storage system (BESS) now operational. At 300 MW/600 MWh, the project represents a major milestone for the UK’s energy transition and we’re proud to have supported Zenobē throughout the planning and consenting process. As one of the UK’s largest battery storage projects, Kilmarnock South will play a vital role in strengthening the electricity network and enabling greater integration of renewable energy. Using advanced grid-forming inverter technology, the facility will provide critical grid stability services traditionally supplied by conventional fossil fuel power stations, helping to create a cleaner, more resilient and flexible energy system. The project’s impact is significant. By reducing renewable energy curtailment and supporting a more stable grid, Kilmarnock South is expected to prevent approximately 3.3 million tonnes of CO₂ emissions over its first 15 years of operation, making an important contribution to the UK’s net zero ambitions. Congratulations to the

New company status will support the next phase of growth for one of the industry’s longest-established power systems software providers. IPSA will now be a separate, standalone company from TNEI Services Limited and officially be known as IPSA Energy Solutions Limited (IPSA). The company will continue to be wholly owned by TNEI Group. The change reflects the company’s evolving role in the energy sector and its ambitions for continued growth in new and emerging markets. IPSA will continue to deliver the power system analysis software, expertise and support trusted by the energy industry for more than 50 years. During this time IPSA has earned a reputation as a trusted partner, helping organisations design, plan and operate reliable and resilient electrical networks. Gorby George, Director, of IPSA Energy Solutions Ltd commented: “Becoming IPSA Energy Solutions Limited is a natural evolution that better represents our role within today’s energy sector while preserving

TNEI has been working with Regen, National Grid Electricity Distribution and Energy Local on the Geoprint for Energy Club Connections and Operations (GECCO) project, exploring whether local energy balancing, the coordination of local generation and demand within a defined area, could make better use of existing grid capacity, reduce pressure on the network, defer costly reinforcement and unlock new renewable connections sooner. A key learning so far is that local balancing is not just a theoretical concept. Previous schemes have shown it can reduce network pressure, enable both new generation and new demand to connect and create measurable financial value. However, not every local supply or market model is relevant for GECCO’s aims. The project has so far reviewed different emerging UK local energy models and grouped them into broad categories, concluding that these models play different roles depending on how directly they interact with the grid and whether they

Last week, colleagues from across TNEI’s global offices came together in Lancaster for a two-day company away day focused on connection, collaboration and the future of the business. Hosted at Lancaster University, the event brought together teams from around the world for the Company Annual General Meeting (AGM), interactive workshops, a group environmental activity, and an evening celebration hosted by Team Africa, who this year is celebrating their 10th anniversary. The event opened with the Company AGM where the TNEI team was provided with an opportunity to reflect on progress, share updates and discuss the direction of the business. The session also saw some colleagues presented with long service acknowledgments celebrating a long career with TNEI – Johan Smith (10 years), Ewan Watson (10 years) and James Mackay (20 years) congratulations! Following the AGM, colleagues moved into a series of mixed-group workshop exercises designed to encourage collaboration and relationship-building across

On 19th June 2026 the UK Government published Assessment and Rating of Wind Turbine Noise (ARWTN) which should be used to assess operational wind farm noise in the UK going forward with immediate effect. The document supersedes ETSU-R-97 ‘The assessment and rating of noise from wind farms’ which has been used to assess wind farm noise in the UK since it was published in 1996. Why are the updated wind turbine noise assessment guidelines important? Operational noise can be a key constraint in the design of a wind farm, influencing the number and size of turbines that can be installed. Noise constraints can also impact operational sites, reducing the amount of energy that can be generated. Robust noise guidance is key to ensuring that any impacts on local residents are properly assessed at the consenting stage and that noise can be controlled via appropriate planning conditions once a site becomes

TNEI recently supported Wilson Renewables IV LLP in securing Planning Permission for the 5-turbine 33 MW Hawkwood Wind Farm, located 6km southwest of Strathaven, South Lanarkshire. The project involved a wide range of services delivered by our team, including: Pre-application consultation with consultees and the local community Co-ordination and compilation of the Environmental Impact Assessment (EIA), including authoring front- and back-end EIA Report chapters Technical assessments covering areas including noise and socio-economics, and authoring associated EIA Report chapters Preparation of the Planning Statement, Design and Access Statement, and Pre-Application Consultation Report Co-ordination and submission of the Planning Application Post-submission monitoring and liaison activities   We were pleased to see Planning Permission granted by South Lanarkshire Council on 12 May 2026, marking an important milestone for the project. Stuart Beattie, Director at Wilson Renewables comments:  “TNEI has played a pivotal role in securing planning consent for our Hawkwood wind farm. Their
