In this webinar we explore how grid constraints are increasingly affecting development and how smart local energy systems could help unlock capacity and accelerate delivery. Hosted by Matthew Capper, with guest Ed Hurford from the Local Energy Markets Alliance (LEMA), the session takes a conversational look at the challenges facing the electricity network and introduces an emerging, market‑based solution designed to address them. The discussion is particularly relevant to those working across planning, utilities and development who are dealing with delays, costs and uncertainty associated with grid connections on new and existing schemes.
The webinar started by highlighting the growing difficulty of securing grid capacity for new development. Rising demand from housing growth, electrification of heat and transport, and the uptake of technologies such as EVs, heat pumps and solar are placing increasing pressure on networks. These challenges are often highly localised, with constraints at substation level limiting what can be delivered. In some cases, developments may face long delays while waiting for network reinforcement works to be completed.
LEMA is an industry‑led, not‑for‑profit alliance bringing together local authorities, network operators, consultancies and technology providers. Its focus is on creating the frameworks needed to deploy existing energy technologies more effectively and at scale. Rather than developing new technology, LEMA aims to unlock the potential of what already exists by coordinating stakeholders and building viable commercial models.
The core solution discussed was the concept of smart local energy systems. These involve homes within a local network being equipped with low‑carbon technologies; such as solar, batteries and EV charging, which are digitally connected and managed collectively. This coordinated approach allows demand to be smoothed and short‑term peaks reduced through dynamic load management. By lowering peak demand at substation level, the system can help release additional capacity on constrained networks.
A key benefit is the ability to bring forward development that might otherwise be limited by grid constraints. By managing peak loads more effectively, network operators can offer earlier connections without waiting for full reinforcement. In practice, this could significantly increase the number of homes deliverable on constrained sites, while still operating within existing infrastructure.
The session concluded by highlighting the importance of building confidence through real‑world projects and collaboration. LEMA is continuing to work with network operators, local authorities and developers to test and refine the approach, with early engagement seen as critical to success.

Transfer slabs are a key component in complex structural design, and evolving regulatory expectations are strengthening how their performance is understood and demonstrated. This article shares our perspective on the Building Safety Regulator’s focus on transfer slabs, outlining what it means for new and existing buildings, and highlighting the value of clear, evidence-led design and proportionate engineering judgement.
As the long-term sustainability and operational efficiency of developments come under greater scrutiny, the balance between initial capital outlay and long-term expenditure is playing an increasingly important role in successful project delivery. In our latest podcast, “Life Cycle & Upfront Costs,” Ben Wakeling is joined by Gerrad Mukuyu to explore how these two critical aspects of project budgeting interact in practice. The discussion focuses on why evaluating a project's financial footprint over its entire lifespan rather than just its construction phase can improve scheme viability, reduce risk, and ultimately create more sustainable, cost-effective assets.
