Associated British Ports – ABP is the UK’s leading port operator, with a unique network of 21 ports across England, Scotland and Wales. Their ports include Immingham, the UKs busiest port, and Southampton, the nation’s second largest and most efficient container port, as well as the UK’s number one for cars and cruise.
In 2016 ABP and its customers handled 89 million tonnes of cargo. They support 119,000 jobs and contribute £7.5 billion to the UK economy every year.
Situated on the south west coast, the Port of Teignmouth is well placed to serve south west England. Ball clay is the port’s principal traffic, handling some 200,000 tonnes each year.
The port also handles animal feed and a wide variety of other dry bulks including grain, agribulks, stone chippings, salt, and forest products, as well as heavy lifts and abnormal loads.
ABP have a company wide policy to deliver renewable technology across all operational ports in order reduce CO2 emissions and energy consumption.
Custom solar secured a framework partnership with ABP via an OJEU competitive tendering process across the whole of the industry which scored the bidders on several factors including; Health & Safety, design & engineering capability, delivery capability and experience in the design and installation of large-scale solar projects.
Custom Solar were appointed to deliver a 50kWp roof mounted system on to the main warehouse on the port to compliment the existing 50kWp system already operating. The system was designed to ensure the size was sufficient to match the sites energy demand so that the power would be utilised. Special access and cable routes were required to avoid an excavation works to connect the system to the main incoming supply point.
ABP Teignmouth had an existing 40kW DNC system connected (50kWp). We installed a second 40kW DNC (50kWp) photovoltaic system with grid limitation to 65kW total export.
Initially a previous contractor was due to install a 200kWp system which would have resulted in the export limit being reached constantly along with a considerable yield reduction as seen at Ayr.
We were appointed to the project and after reviewing the half hourly data recommended a 50kWp system be installed instead of the 200kWp previously proposed. This was in line with matching the generation to the site demand and therefore preventing the power limitation impacting on yield/performance.
We successfully installed the power limitation system to satisfy the DNO requirements, this was achieved using the Fronius Smart meter system. Such was the DNO’s comfort in our experience with this technology a DNO witness test that would usually be required was not needed and therefore allowed us to connect the scheme 4 weeks earlier than expected.
We can now provide examples from our monitoring of the limitation in action on a few days from this summer, where exports would have exceeded 65Kw. As this was an LV connected system, no secondary export limit was required. The Fronius Smart meter system allows the graduated reduction in output, to avoid grid interference.
Custom Solar operate and maintain all of the systems across the port providing live monitoring via our bespoke monitoring solution, full reactive maintenance and annual scheduled service visits.
