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

The Scottish Government has published new Hydrogen Planning and Consenting Guidance (February 2026), providing long-awaited clarity on how green and blue hydrogen projects should progress through Scotland’s planning and regulatory system. Importantly, the guidance does not apply to grey hydrogen, which remains unsupported due to unabated emissions. The guidance confirms that hydrogen is now firmly embedded in Scotland’s planning and energy policy framework, with strong support through the National Planning Framework 4 (NPF4), the Hydrogen Action Plan and national net-zero commitments. In principle, planning authorities are encouraged to take a positive and proportionate approach to hydrogen development — but only where impacts, risks and safety are clearly addressed. A central message throughout the guidance is the critical importance of early pre-application engagement. Developers are strongly encouraged to engage early with planning authorities, Scottish Environment Protection Agency (SEPA), the Health and Safety Executive (HSE) and (where relevant) marine regulators to agree

We’re excited to announce the development of an advanced scenario-based power flow solver with deep uncertainty modelling for load and generation as the result of two years of collaboration between TNEI and Glasgow Caledonian University as part of a Knowledge Transfer Partnership. This innovative tool was designed to transform network planning for Low Voltage (LV) networks and beyond and will be integrated into TNEI’s IPSA software to further enhance its capabilities for power system planning and analysis. Key highlights of the solver: Unmatched Speed – Executes all scenarios with 100% accuracy while eliminating the need for traditional Monte Carlo simulations –  achieving speed gains of up to three orders of magnitude. Robust Convergence – The unique formulation ensures superior robustness and convergence compared to classical methods. Scalability – Accurately handles complex, multiphase networks and components with ease. LV Network Planning – Enables smarter, more efficient planning of low-voltage networks for future energy systems. We are also
