UTILITY WEEK | 21ST - 27TH JULY 2017 | 5 United Utilities has sponsored a show garden created by award-winning garden designer John Everiss. The "Slow The Flow" garden has been on display at the RHS Tatton Flower Show and aims to raise awareness of the problems that urban development can cause for public drainage systems. Everiss said: "I've used a number of different techniques to help people see the possibilities. There are subterranean water storage channels, gabion walls, permeable paving and a living green roof, to name a few ideas." ELECTRICITY EDF buys 11 windfarm sites in Scotland EDF Energy Renewables has bought 11 windfarm sites in Scotland from Partnerships for Renewables. The sites have a total potential capacity of 600MW. Three of them with around 100MW of capacity already have planning consent. One site is in the planning system already and seven other sites are in development. The majority of the projects are on land managed by Forest Enterprise Scotland. The company currently has 319MW in operation in Scotland and more than 1GW in development. EDF Energy Renewables' chief executive Matthieu Hue said the company had "a well-established strategy to grow our business either by developing our own sites or through acquiring high- calibre projects". WATER Pollution incidents up The number of pollution events caused by water and sewerage companies in England has risen for the first time since 2012. According to the Environment Agency, the number water quality incidents rose from a low point of 1,742 in 2015 to 1,902 last year. The agency said five of the nine companies had an increase in total incidents between 2015 and 2016. The agency said it would be meeting with companies that saw reductions to understand how this was achieved and to encourage shared best practice. The total number of serious incidents (categories 1 and 2) fell last year to 57, from the 59 in 2015. However, the EA said it was "disappointed" that category 1 incidents had risen to nine from the lowest ever level of four seen in 2014 and 2015. "There is absolutely no legal reason for the UK to withdraw from Euratom" Simon Stuttaford, head of nuclear, DWF Llp National Grid has released its 2017 Future Energy Scenarios report setting out possible trajectories for the energy system out to 2050, including scenarios for uptake of electric vehicles and smart products. This year's iteration of the annual research also showed National Grid significantly scale back its forecasts for growth in energy storage capacity.
