Power On delivers major grid connection and primary substation for Stansted North Site development
Posted by: electime 27th April 2026
Leading electricity and multi-utility connections specialist Power On has delivered the extra high-voltage (EHV) and high-voltage (HV) electrical infrastructure for Stansted North Site – a landmark 170-acre commercial development located north of Stansted Airport’s runway.
Power On was appointed as Principal Designer and Principal Contractor, delivering a fully integrated, end-to-end infrastructure solution from feasibility and point of connection through to construction, energisation and long-term operation.
Appointed by Threadneedle Columbia Ltd, Power On provided a new 33kV grid connection from UKPN’s Bishop’s Stortford substation, alongside the design and construction of a new 33/11kV primary substation to power the scheme.
Neil Fitzsimons, Managing Director at Power On, said: “Our integrated delivery model combined immediate technical expertise with long-term strategic value. The Stansted North project is a clear example of this approach in action, supporting both the immediate delivery of the scheme and its long-term ambitions.”
The development will comprise multiple commercial units ranging from 30,000 sq ft to 1,000,000 sq ft, creating a strategic hub for e-commerce, life sciences, technology and logistics businesses in a prime South East location.
Matt Burgin, Stoford Developments, on behalf of Columbia Threadneedle, said: “Power On’s early feasibility work gave us a clear understanding of risk and cost, providing commercial certainty at a critical stage of the project.”
The masterplan is underpinned by a long-term energy strategy focused on reducing carbon impact through efficient energy use, sustainable material selection and the integration of low-carbon technologies. The primary substation infrastructure has been designed to support this strategy and enable phased expansion as the site evolves.
