Germany’s sonnen introduced a scheme a while back in which customers pay a flat, reduced rate for their electricity each month while the company aggregate their batteries together to benefit the grid – and now the offer has been extended to electric vehicle owners.
Carsten Reincke-Collon of Younicos continues his look at the potential – and limitations – of using blockchain in the energy system. This second part covers how energy storage and storage management software could be the key to the ‘puzzle’.
Blockchain technology is being touted as the next big step forward in the digitalisation of the energy system. But storage and storage management software are the critical pieces of the puzzle needed to maximise its potential, writes Carsten Reincke-Collon of Younicos.
A 250-home ‘virtual big battery’ was switched on in Canberra, Australia last week, allowing residents to sell solar-generated power at a significantly higher price than available to them through feed-in tariff (FiT) policies.
Northern Powergrid, one of the six distribution network operators (DNOs) responsible for delivering power across regions of the UK, is to plough £1.9 million (US$2.53 million) into the creation of a smart energy grid across its network, allowing its eight million customers to trade power and services using their home solar, battery systems and electric vehicles (EVs).
Eelpower has commissioned a 10MW battery energy storage system (BESS) in England, backed with both frequency response and capacity market contracts, in the first of a new pipeline of projects being planned by the company over the next decade.
What is thought to be the largest operating containerised vanadium redox flow machine system in the UK has been connected to the grid by manufacturer redT energy, with the 1MWh project becoming the first to sign up to a local energy market being set up by British multinational utility Centrica.
In its home territory of Germany, energy storage provider Sonnen is making a play to replace utilities, but its business models in the US will instead emphasise cooperation with existing energy suppliers.
