Our innovative technical solutions resulted in a vastly reduced project lead time and subsequently significant cost savings for the client.

Project details

Demonstrating the company’s commitment to implement more resource-efficient methods in its manufacturing process, the ‘hard-wired’ solar development will provide 30% of the site’s annual electricity demand, enabling the facility to reduce its carbon footprint and reliance on the national grid.

Green Frog Connect were responsible for the turnkey design and installation of the 11kV cable that connects the solar park to the factory, as well as an extension of the existing 11kV switchboard which allowed the solar park to be integrated into the factory’s existing network.

The project, which in part aimed to address the company’s sustainability concerns, was made technically challenging as the solar farm is located some distance from the factory itself. The existing Distribution Network Operator (DNO) metering substation supplying the factory required a generator constraint panel for the solar farm which was located two kilometres away.

In partnership with the rest of the project team, our challenge was to find a reliable solution to transfer the constraint signals to the solar park. With tight client deadlines and restrictive manufacturer availability, we designed and built our innovative technical solution in-house.

Using a fibre cable, complete with programmable converters, we were able to transform the hardwired volt free contacts via the ethernet. Our technical specialists designed and personally built the required panels mirroring each other at the remote ends. Each panel is built with an integrated supply unit with battery support should external supplies fail. We addressed any potential failure in communication by building in a watchdog for continuous monitoring to curtail generation if required to avoid tripping of any existing factory supplies.

Project details

With the cable route from outside the business park to the substation at over 1km long, and being the main feeder to the M6, the local highways team deemed this a highly traffic sensitive network and a critical emergency route in the event of any motorway congestion. Detailed discussions with local highways and businesses were required to ensure that traffic flow was maintained with any potential disruption minimised.

At the same time, and adjacent to the Gas Plant being constructed by Green Frog Connect, a 50MW Battery Energy Storage Plant was in development. In collaboration with this site, Green Frog Connect extended their contract to facilitate the off-site cable route for both developments which subsequently consisted of 4No 33kV circuits and corresponding pilot circuits. Working to extremely challenging timescales, an intricate program and complex traffic management plan was devised and agreed with all stakeholders. By operating continuous shift patterns, a 30% program improvement was achieved, enabling the successful energisation of the BESS site ahead of the Winter Triad trading period and ensuring essential balancing services to the National Grid during high usage periods, mitigating potential power outages.

On site as the Principal Contractor, Green Frog Connect provided full turnkey services for this gas project. Our scope of work included the design and construction of the balance of plant, including switchgear, transformers, power and control cabling for the client’s SCADA
system, security control systems and auxiliary power supplies, along with the design and construction of the civil works including ground works, reinforced concrete structures, fencing and access roads.

Following the successful sign off of the revised G99 commissioning procedure for the site’s 27 GE Jenbacher gas engines, the site was available for the client to trade and meet its Capacity Market obligations.

Our project management resulted in a 30% program improvement for the off-site grid connection cable works ensuring supplies were available ahead of the Winter Triad trading period.

The existing DNO metering substation supplying the factory required a generator constrain panel for the solar farm which was located some two kilometres away. Our challenge was to find a reliable solution to transfer the constraint signals to the solar park.

Our solution was to use a fibre cable, complete with programable converters, to transform the hardwired volt free contacts via the ethernet. Due to tight client deadlines, and typical manufacturer availability, we designed and built the required panels mirroring each other at the remote ends. A built-in watchdog for continuous monitoring ensured any failure in communication would curtail generation and avoid tripping of any existing factory supplies.

Client: Green Frog Power

Key client benefits

• We designed and negotiated a simplified connection arrangement which saved the client in excess of £500k compared to their original arrangement.
• We diverted a private overhead line that was originally routed through the site and managed all outages to ensure that the businesses being fed did not lose supply.
• A shared electricity and gas trench for the off-site connections was coordinated to minimise costs and reduce the amount of disruption to the local community.
