One of our recent articles explained how rooftop solar PV is more expensive that a centralised supply, and that the transmission and distribution cost savings of the rooftop system, on their own, do not make up for this cost difference. Here, Javier López Prol at the Wegener Center for Climate and Global Change, University of Graz, responds to those challenges. First, the economies of scale of distributed rooftop solar are yet to be realised. … [Read more...]
Sweden’s new “prosumers”: electricity generation at the city, village and residential level
54% of Sweden’s power already comes from renewables – the target is 100% by 2040 - and more and more is being generated locally on a small distributed scale, says Harry Kretchmer writing for the World Economic Forum. ‘District Heating’ plants are today using excess heat to warm over 75% of Swedish homes. Residential generation is happening too, creating “prosumers” who both produce and consume. In Ludivika, 1970s flats have been retrofitted with … [Read more...]
Virtual blockchain for prosumers replicates a live utility-scale grid
Wayne Hicks at NREL describes research that’s created a virtual blockchain “prosumer” accounting system that replicates a live utility-scale grid. The goal of a real-world application is to allow countless individual households with their own electricity storage and generation to buy and sell power to each other; a truly revolutionary pathway. Clearly, it will require a system that securely accounts for vast amounts of transactions - a big enough … [Read more...]
DSOs can use digitalisation to empower all grid stakeholders
Distribution System Operators (DSOs) are in charge of operating, maintaining and developing the distribution network to ensure that electricity is delivered to end-users in a secure, reliable and efficient manner. Harry Taylor, Chris Collins and Erik Rakhou at Baringa Partners spell out what DSOs need to do to take full advantage of digitalisation technologies and processes to make them fit for a rapidly transforming energy system. A growing … [Read more...]
Is Blockchain a disruptor? Or the solution to an already-disrupted energy sector
The global energy sector is already facing multiple, concurrent disruptions that are fundamentally transforming electricity markets around the world: digitalisation, decarbonisation, decentralisation, and electric mobility. It’s creating residential prosumers, with their solar panels, electric vehicles, smart thermostats (the list is growing) and a predicted global installed distributed energy resources (DERs) capacity of 530 GW by 2026, … [Read more...]
RWE’s Head of Innovation Inken Braunschmidt: “We want to be the Uber for energy”
Big energy companies are looking to the sharing economy, digitisation, big data, and mega-cities to inspire future revenue streams. In this exclusive interview with Energy Post, Inken Braunschmidt, leader of RWE’s “Innovation Hub” talks about her unique role at the helm of a department that’s not a department. Her job? To think non-utility ideas. Braunschmidt:”We’re really going to the edge of what energy has meant for 100 years.” … [Read more...]
