UTILITY WEEK | 28TH OCTOBER - 3RD NOVEMBER 2016 | 17 Operations & Assets A significant number of events reduced load by more than 10 per cent. The effects of these operations were broadly imperceptible to the customer and were done through a fully automated open ADR portal, which enabled SSEPD to manage the load of the 30 partici- pant customers almost instantaneously. With ADR it is important to avoid a nega- tive impact on building occupants and to ensure customer satisfaction and continued commitment to future demand response pro- grammes. Larger buildings are more likely to have a greater capacity to reduce load, and buildings with higher energy efficiency standards (that is with better insulation or air circulation) may be better suited to more intensive ADR. Scottish and Southern Electricity Net- works learnt a number of key lessons during the ADR trials, particularly around the early installation of data service technology, devel- oping appropriate incentives and operating schemes for participants to ensure optimum take-up of the ADR opportunity. NTVV is a window on the future The NTVV trials have provided a window into a future where a DNO can use customer flex- ibility provided by smart technologies to bet- ter fulfil Ofgem's RIIO (revenue = incentives + innovation + outputs) price control out- puts. By working together with consumers in this way, DNOs can create a more dynamic, sustainable and lower carbon network, while simultaneously putting stakeholders at the heart of the decision-making process. These technologies will be required to better meet the significant challenges that DNOs will face in coming years as energy production and use becomes increasingly decentralised and the network companies are required to play far more active roles in the operation and delivery of a sustainable, lower carbon energy system. Technology can allow customers to sup- port the network, but why should they help? In this article, we have given some exam- ples of how customers can help to more efficiently manage the distribution network. However, it is not always easy to convince them why they should do it. In the next article, we will show how the NTVV project also looked at ways a DNO can interact with consumers to encourage network-friendly behaviour. This article is the fourth of five which look at how Scottish and Southern Electricity Networks and the NTVV project have been exploring better ways of managing distribu- tion networks. Next week, we will show how lessons learned in NTVV showed how DNOs can better effectively with consumers.
