Carrington Combined Cycle Plant at
commissioning stage
NEW SUBSTATION FOR EAST ANGLIA ONE
D
F, through its DF Energy division, and in consortium with General Electric, has delivered the combined
cycle power plant in Carrington, UK, to the client. The project will begin operating commercially once the facility commissioning is complete. The Carrington power plant is an 880 MW combined
cycle located in Trafford, Greater Manchester and consists of two 440 MW units each fired by natural gas. Now that it is finished, the plant is capable of supplying enough energy to cover the needs of around a million homes. DF Energy has invested almost 5 million man-hours in
the project (including both direct and indirect jobs) and at times there were almost 1,000 people involved in the work. The gas-based plant is expected to have an operational
life of more than 25 years. The power station has been built on the fully decommissioned and demolished Carrington coal-fired power station in Greater Manchester. The site lies between the villages of Carrington and Partington, approximately 12km south-west of Manchester city centre. The combined-cycle power plant comprises two Alstom
GT26 gas turbines, two horizontal triple-pressure heat recovery steam generators (HRSGs), two TOPGAS hydro- gen-cooled turbo generators and two STF15C steam tur- bines with axial exhaust. The plant is expected to operate at a fuel efficiency rate of approximately 57%. The GT26 gas turbines are equipped with Alstom's
unique sequential combustion technology to achieve high- performance output by burning fuel in two, dry low-NOx combustor stages. The HRSGs are equipped with Alstom's optimised for cycling and constructability (OCC) tech -nology for achieving high flexibility for reliable high-cycling duty.
The combined-cycle power plant is designed for auto-
matic control from a central control room (CCR) featuring a plant control console for start-up, on-line operation, and shutdown of gas and steam turbines. The plant also houses an auxiliary boiler to supply steam for start-up of the steam turbines and an emergency diesel generator to facilitate safe shutdown.
E.ON has been awarded a contract with the UK’s National Grid to support the power grid’s stability with an innovative battery solution. With the strong growth of weather- dependent renewable sources such as wind and solar, the amount of power fed into the grid is becoming increasingly volatile. National Grid was responsible for launching this tender for a new service to deal with volatile fluctuations. As one of the first of its kind in Great Britain, E.ON’s battery system will help balance demand and supply in real time ensuring that the power supply and quality is maintained. The solution makes it even possible to increase the share of renewable energy in the grid. The 10 megawatt lithium-ion battery with a size of four shipping containers has an equivalent power of roughly 100 family cars. The tender for this new service was highly competitive; National Grid received 243 different
tender options and awarded just 8 contracts. E.ON will build the 10 MW battery at E.ON’s Blackburn Meadows Biomass CHP and District Heating site near Sheffield. The system is planned to be operational by the start of 2018. Karsten Wildberger, member of the E.ON board, told UKPN: “We are delighted to build one of
the first commercial battery systems in the UK. This is a milestone for E.ON in the new energy world and an important recognition of the enormous potential battery solutions bear. We continue to work on new storage solutions going beyond security of supply, for example combining applications to increase self-consumption, shave peak-loads or to improve service for our industrial and commercial customers.”
8 AUTUMN 2016 UK POWER NEWS
IBERDROLA UK has award- ed Navantia Puerto Real a contract worth in the region of €65 million to build the substation for the East Anglia One offshore wind farm, which the electric utility is currently developing in English water, and which will have a capacity of 714 megawatts. The EA1 Project is being developed by East Anglia ONE Limited (EA1), which is a joint venture between ScottishPower Renewables (UK) Limited (SPR) and Vattenfall Wind Power Ltd (Vattenfall). SPR is the UK’s leading
onshore wind developer and is part of the Iberdrola Group which is one of the world’s largest utility companies and a global leader in wind energy. Vattenfall is a current
subsidiary of the Swedish energy utility which has one of the largest portfolios of offshore wind plant in Europe. The EA1 Project is the first of up to twelve projects in the East Anglia Round 3 zone (EA Zone), one of the largest offshore wind zones for devel- opment in Europe. The zone offers very favourable conditions including the low- est water depths on average in Round 3, convenient loca- tion near demand centres and benefits from good wind con- ditions. This may be the first UK off- shore project to use an HVDC Grid connection. This, in turn, will offer opportunities for UK inward investment to build on the UK’s current engineering expertise in this field. This is the first of 12 similar projects in the EA Zone.
PX ENGINEERING AWARDS BIOMASS CHP PROJECT TO
POYRY
PX Engineering Consultants Limited, part of the PX Group, has awarded Pöyry with the technical services assignment for their Technical Owner's Engineering contract with MGT Power Ltd for the 299MWe biomass CHP Plant to be constructed in Teesport, North-East UK. During the early stages of project development, Pöyry provided MGT with front end engineering design and, during the final stages up to financial close, and full technical support for the EPC contract. This new assignment for the
initial implementation phase includes assistance in design review and construction supervision together with technical support during erec- tion, commissioning, testing and hand-over, and support during the warranty period. MGT Power is an indepen-
dent British company focused on large scale biomass projects which use sustain- able forestry as fuel supply. The £650m Tees Renewable Energy Plant (Tees REP) will utilise sustainable biomass fuels, from the UK and global- ly, to generate around 2.4 TWhrs of electricity each year.
