This week TNEI’s Charlie, Rory and George were involved in The Learning Partnership’s Race to the Line challenge, an inspiring initiative designed to give students real-world exposure to engineering, problem-solving and teamwork.  The Race to the Line challenge brings together schools and industry partners to help students apply science, technology, engineering and mathematics (STEM) learning in a practical and engaging way. Pupils are encouraged to think creatively, collaborate effectively and develop solutions that mirror the challenges faced by engineers in the real world.  Pupils were tasked with designing, building and racing their own cars. TNEI worked alongside students offering guidance and helping them explore how engineering principles are applied in practice.   The collaboration gave students exposure to:  Engineering problem-solving and critical thinking  Working to briefs, deadlines, and constraints  Team collaboration and communication  Insight into careers within engineering and the energy sector  TNEI’s Electricity Network Lead Charlie Thompson organised the day with St Paul’s school and the Learning Partnership: ‘We had a fantastic day designing, creating and racing high speed cars with the pupils at St Paul’s

The first Common Information Model (CIM)-based Long-Term Development Statements (LTDS) models were published by Distribution Network Operators (DNOs) in Great Britain in November 2025. Here’s TNEI’s take on them, what that means, and what’s coming next. What is the Common Information Model (CIM)? Common Information Model (CIM) is an internationally recognised semantic data model for power systems, defined under International Electrotechnical Commission (IEC) 61970 and 61968. It provides a consistent way to represent network components, topology and parameters, and improving interoperability between software tools and reducing reliance on bespoke formats. The Common Grid Model Exchange Specification (CGMES) is a set of CIM profiles developed by ENTSO-E that constrain CIM for specific grid-modelling use cases, enabling models to be exchanged and re-used consistently across parties and platforms. This is the standard applied in the GB context. How is CIM being implemented for GB distribution networks? Two things appear to be driving

TNEI is delighted to share the successful delivery of a full UK Grid Code Compliance (GCC) study and model submission for a co-located Battery Energy Storage System (BESS) and Solar PV project.   The project combined solar generation and battery storage on a shared grid connection, creating a coordinated hybrid energy system that required specialist technical expertise and a robust compliance approach.   With hybrid and co-located assets accelerating across global energy markets, the need for accurate modelling, robust compliance and clear technical direction has never been more important for developers.   As a long-standing client, the developer trusted TNEI’s proven track record in delivering hybrid-site projects.  Our role was to ensure that both technologies operated seamlessly – individually and together – providing a compliant and low-risk route to grid connection.    Our work followed the latest industry requirements outlined in the Electro-Magnetic Transient (EMT) Models Guidance Note and the Co-location Guidance Note, ensuring alignment with current UK Grid Code standards.     Whether you are in

What started as a small power system consultancy in Cape Town has grown into a trusted partner supporting projects across the energy sector. Today, TNEI Africa (Pty) Ltd works alongside developers, contractors, OEMs and fellow consultancies to deliver grid studies, grid code compliance, complex power system analysis, and strategic grid advice. Over the past decade, we’ve had the privilege of contributing to projects that help strengthen power systems and enable the integration of renewable energy across the continent. A big thank you to our clients, partners, and our incredible team – your collaboration, expertise, and trust have made this journey possible. As the grid continues to evolve, we’re excited to keep playing our part in supporting the energy transition and shaping the future of power systems in Africa. Here’s to the next decade. To mark the celebrations some of the team took part in the Cape Town Cycle Tour on 8th March. This is the world’s largest timed cycling

On 26 February the City of Johannesburg Library hosted a career guidance event for over 50 young girls aged 12 to 14 years across Johannesburg. The aim of the day was to raise awareness and spark early interest in various career paths within Science, Technology, Engineering and Mathematics (STEM). The event brought together exceptional and well-accomplished female engineers from various organisations, including the Women in Engineering from National Transmission Company of South Africa (NTCSA), formerly known as Eskom Transmission and the Conseil International des Grands Réseaux Électriques (CIGRE) Southern Africa Women in Energy (WiE) initiative, which Neo Mapapanyane, a Principal Consultant at TNEI Africa, chairs. Speaking about her experience, Neo shared: “Encouraging curiosity in young minds is one of the most powerful ways that we can shape the future of our industry. As the chair of CIGRE SA Women in Energy (WiE), I am extremely passionate about supporting the next

Following a first round of consultation in 2025, the Scottish Government has now released a second Working Paper on Refreshing the Good Practice Principles for Community Benefits from Onshore Renewable Energy – open for consultation until the 25th March 2026.  Here’s a summary of what you need to know: The Working Paper is seeking views on the following: The technologies in scope of the Good Practice Principles (GPPs), and the approach to co-located developments; The community benefits fund levels recommended by the Good Practice Principles; Principles and Guidance for the governance and distribution of community benefit funds; and Measures to support communities and build their capacity to engage with and fully benefit from community benefit funds. The Working Paper summarises the responses received during the first consultation period and sets out proposals to strengthen the Good Practice Principles. As the GPPs are currently based on the commercial viability and maturity
