NETWORK / 13 / DECEMBER 2018 / JANUARY 2019 T he electricity and gas networks are no longer the hidden heroes of the energy industry. Over the last few years they have been steadily improving their service for the public – delivering lower cost and more reliable power and gas than ever before. Power cuts are fewer and shorter while the gas network is so reliable that the probability of an unplanned supply inter- ruption is once every 140 years. The pace of change we are seeing is set to accelerate. Ofgem deserves credit for their decision to put such a fo- cus on innovation into the RIIO price control process. This has allowed the UK's networks and technology providers to become global leaders. The RIIO innovation stimulus has had signi cant success in encouraging network companies to bring forward innovative pro- jects. It is vital, therefore, that innovation in networks contin- ues to be strongly incentivised under future price controls, as the networks deliver their cru- cial role in developing the future energy system, decarbonising at the least cost to the public. Driven by decarbonisation, digitalisation and decentralisa- tion, network innovation pro- jects are already helping energy network operators identify new ways of better serving their cus- tomers by developing quicker, more e„ cient and cheaper ways to deliver a cleaner energy system. As a result, electricity and gas network companies are now DECARBONISATION playing an ever more impor- tant role in developing a future energy system that is cleaner, with more renewable energy and smarter technology. Allow- ing them to innovate has proved vital in helping them to manage the electricity and gas networks more e„ ciently – keeping costs down for the public while also helping to reduce carbon emis- sions. Independent research carried out by Pöyry has shown that existing innovation projects developed by electricity network operators alone under the Low Carbon Networks Fund could deliver up to £1.7bn of bene ts by 2031. Low carbon gas Take up of new technologies is increasing signi cantly. This includes the introduction of green gases such as biomethane and synthetic gas, research into hydrogen for heat and transport, smart meters, energy storage and low carbon vehicles. It is clear that the public is exercis- ing greater choice and control over the way in which they use energy. Innovation for the nation Decarbonisation is changing the energy system rapidly and the way in which energy is produced, supplied and consumed is already very different from only a few years ago. Randolph Brazier, head of innovation at the Energy Networks Association (ENA), looks at some of the key trends in this space. Along with biomethane, bioSNG and hydrogen the new plastic gas mains save 240,000 tonnes of carbon a year and will enable the grid to carry more low carbon gas. New technolo- gies such as hydrogen are also now allowing companies to become global leaders and develop the high skilled jobs of the future. Over 90 sites that have been built to produce green gas are now connected to the network. These sites now contribute more than 2.5TWh to domes- tic gas production, supplying over 300,000 homes with low carbon gas. Up to 50 more are expected to be commissioned by January 2020. On the electric- ity side, an increase in ™ exible generation e.g. storage along with new technologies will help to create new markets to enable ™ exibility services that will compete alongside traditional investment. The Energy Network Association's Open Networks Project is a world-leading energy industry initiative that will shape the way our energy networks work in future. Electricity and gas networks both have a vital role to play in enabling the low carbon transi- tion. As we look to decarbonise heat, transport, and electricity generation it will be important for government to look at the system as a whole. Given the success of existing RIIO incentives in supporting the low carbon transition and helping networks keep costs down for the public, it's vital that these incentives remain strong in future price controls.
