Hanab Energy Solutions, a division of Hanab, is one of the Netherlands’ leading electricity infrastructure contractors, delivering major transmission and energy infrastructure projects up to 380kV. Working extensively with TenneT – the Dutch transmission operator, broadly equivalent to National Grid in the UK – Hanab Energy Solutions also supports major private-sector clients including data centres and large energy users. Backed by a wider group with significant technical capability, operational systems and financial strength, Hanab Energy Solutions has built an outstanding reputation for delivering complex infrastructure projects safely and at scale.

This acquisition strengthens Hanab’s position in the UK, with the UK identified as a key long-term growth market. The accelerating demand for grid modernisation, renewable energy connections, battery storage, data centres and wider electrification presents a major opportunity for investment and expansion in the UK energy sector.

Hanab chose Green Frog Connect because of the position we have built in the market and the direction we are already heading in. We have established a strong reputation for delivering technically complex grid connection projects and is one of the few ICPs actively pushing into higher-voltage infrastructure work. Our proven capability at 132kV, combined with our ambition to move further into EHV and transmission-level projects, made Green Frog Connect a compelling strategic fit.

With Hanab’s support, we will be able to accelerate our growth plans, strengthen our technical capabilities and continue expanding into larger and more complex projects across the UK energy infrastructure market. Just as importantly, Hanab Energy Solutions share our long-term vision for building a leading UK transmission and EHV infrastructure business.

It’s a natural match. We share the same commitment to safety, sustainability, engineering excellence and – most importantly – putting people first. We have thoroughly enjoyed welcoming members of the Hanab leadership team to our offices and project sites in recent weeks, and we are genuinely excited about what we can achieve together.

This is a significant milestone for Green Frog Connect, our team and our clients, and we look forward to the opportunities ahead as part Hanab Energy Solutions.

Client: AMP Clean Energy
Services: ICP, Engineering, Procurement and Construction services

Project details

The purpose of the project was to help support the growth of renewables by providing energy on-demand when the wind doesn’t blow and the sun doesn’t shine. This helps to balance the electricity grid ensuring that enough power is generated whilst supporting the transition to a low carbon economy. Green Frog Connect were appointed to act as the ICP for grid connections and as EPC for the construction of the six gas peaking power plants as part of AMP Clean Energy’s Urban Reserve project.

We faced a challenge in that all of the sites were located on brownfield industrial estates. Using our expertise we saved space and ensured that all sites were built to the highest safety standard whilst accommodating multiple activities. The first project began in late 2020 with each following mobilisation taking place on a weekly basis. The first site became fully energised in March 2021.

All six sites were up and running simultaneously and throughout the project Green Frog Connect demonstrated the depth and flexibility of our construction teams to ensure that AMP Clean Energy was confident in our delivery promises.

Our initial appointment was to undertake the contestable design and place orders for long lead time equipment. The client’s gas engines and HV switch room had already been ordered which helped to reduce construction activities to 20 weeks per project. We had full responsibility for the contestable works, site civil construction, the electrical balance of plant installation and co-ordination of the full site commissioning through to client handover.

Green Frog Connect managed to maintain momentum across the project and ensured all sites were connected on time and within the budget set by the client. We worked closely with the client’s Original Equipment Manufacturer (OEM), co-ordinating all activity with the Distribution Network Operator to ensure that the client’s route to market was achieved at the earliest opportunity.

In any team endeavour, the key to harmony is great communication. This includes all parties knowing how responsibilities are to be divided, with collaborative flexibility in those lines to ensure the best possible end result. The commitment on all sides to complete the project without undue delays meant that we worked together and brought it over the line on time.

The post Green Frog Connect celebrating teamwork making the dream work in Blackpool appeared first on Green Frog Connect.

Given that Bristol was the first British city to be named European Green Capital, celebrating the city’s innovative responses to urban environmental challenges, we feel a strong synergy. Bristol’s commitment to clean transport and energy, and its role as a low-carbon hub of industry fits seamlessly with our mission. We like to punch above our weight, and as Bristol influenced international policy at the UN climate change summit in Paris in 2015, sharing best practice and presenting ambitious sustainable action, we’re very hopeful that our next bright sparks are here!

As a growing company in an evolving sector, it is vitally important to us to bring young talent with fresh energy and ideas into the team. Blending that with our experience and specialist expertise is how the magic happens and Green Frog Connect keeps moving forward and playing the role we’re passionate about in taking the UK to net zero.

University of Bristol’s Spring careers fair is very much focussed on immediate vacancies, graduate roles, work experience and internships.
