Utility Week

UTILITY WEEK | 31ST AUGUST - 6TH SEPTEMBER 2018 | 5 NUCLEAR Bechtel to manage Wylfa plant Horizon Nuclear Power has appointed Bechtel as the project management contractor for the proposed Wylfa Newydd nuclear plant on the Isle of Anglesey. The company has also signed further contracts with Hitachi Nuclear Energy Europe and JGC New Energy UK for the continued provision of support during the development stage. Together with Horizon, Bechtel will oversee the construction of the power station in North Wales, managing the contractual and commercial arrangements with suppliers on behalf of the developer. Nearly 200 of its employees will be embedded within Horizon. Wylfa Newydd will generate power using two 1.35GW UK advanced boiling water reactors supplied by Hitachi-GE Nuclear Energy. ELECTRICITY Tidal turbine hits record output A Scottish tidal turbine has generated more power over the past year than the entire wave and tidal energy sectors in Scotland in the 12 years before its launch in 2016. Scotrenewables Tidal Power's 2MW SR2000 unit clocked up more than 3GWh of renewable electricity in its first year of testing at the European Marine Energy Centre in Orkney, the company said. The SR2000 is described as the "world's most powerful operating tidal stream" and has, at times, supplied over a quarter of the electricity demand of the Orkney Islands. In 12 months of continuous operation – which included the "worst winter storms in recent years" – the unit supplied electricity equivalent to the annual demand of 830 UK households. Andrew Scott, chief executive of Scotrenewables Tidal Power, said: "The SR2000's phenomenal performance has set a new benchmark for the tidal industry." (see analysis, p18) Thames Water has launched a three-pronged aerial attack in its hunt to find and fix leaky pipes. The company is using a fleet of drones, an aeroplane and a satellite to support its mission to get back on track with its leakage targets by 2020. The "eyes in the sky" use thermal imaging and infrared cameras, and the technology is "providing an invaluable tool in the fight against leakage", Thames said. "A farmer with a solar installation or a supermarket with excess energy from its cooling units will be on the same footing as a giant power station" Limejump chief executive Erik Nygard speaks at the launch of the company's 168MW virtual power plant, the first balancing mechanism unit to be aggregated across multiple grid supply points. With the right policies in place, the north of Scotland could become a huge source of power for the rest of the UK as renewable capacity soars over the next decade. Scottish and Southern Electric- ity Networks has outlined a series of credible scenarios for the future of energy in the region. In the proactive decarbonisation scenario, generation capacity nearly triples from 5.8GW today to 15.7GW by 2025/26, with renewables providing 14.3GW.
