How do you double or triple your existing power transmission capacity when costs are rising and you face local opposition to the disruption? Zach Winn at MIT describes a new innovation that uses superconductors designed to transport five to 10 times the amount of power of conventional transmission lines, using essentially the same footprint and voltage level, carried on otherwise standard overhead lines. The superconducting cables (with much of … [Read more...]
Upgrade the grid, or avoid by incentivising flexibility? Electricity demand mapping can tell you what to do
Power grids across the world need upgrading to accommodate the rapidly rising amount of electricity being generated. Without it, it is a serious bottleneck to the transition to clean fuels. Sheridan Few at the University of Leeds summarises his co-authored study that creates a map of where upgrades are most needed in the UK. The map’s purpose is twofold. Firstly, it predicts where power consumption will rise the most and the upgrades are … [Read more...]
How to handle rapid Grid load growth: Data Centres can set the template for EVs, Buildings, new Industry
Due to their growing power demand, data centres can set a precedent for how to handle rapid load growth in a way that supports the grid and ensures reliable, resilient, carbon-free electricity. In other words, they can set the template for the coming surges in demand from EVs, buildings electrification, and the new rich-world policies of onshoring industry and manufacturing, explain Alexandra Gorin, Roberto Zanchi and Mark Dyson at RMI. Big, … [Read more...]
V2G: modelling how EV batteries can provide storage to the grid
V2G (vehicle-to-grid) technology allows parked EVs to store and/or inject electricity into the grid when needed. The main benefit is to avoid the expense and disruption of building dedicated large-scale grid batteries when EVs and charging infrastructure are already ramping up. Though most EVs and charge points are not V2G-ready, now is the time to plan ahead, measure the true potential and identify the challenges. Ibtihal Abdelmotteleb, Matteo … [Read more...]
What China, Germany, and Texas tell us about Capacity Adequacy
As intermittent renewables penetrate further into the grid mix, reliable firm power generation is needed for whenever there is a shortfall. But back-up power, by its nature, has unreliable utilisation rates. And up-front costs for new plants are high, be they gas-fired plants, coal, nuclear, or large-scale storage. That makes future profitability uncertain, and private investors nervous. Hence the need for “capacity mechanisms” that guarantee … [Read more...]
Europe’s cross-border Interconnectors: how JAO auctions optimise energy flows, prices
Interconnectors allow for cross-border flows of energy between two markets that would otherwise not be connected. Through an economic convergence between supply and demand, the cheapest marginal producer located anywhere in these two markets should be able to set market prices. As Jean-Baptiste Vaujour at the Emlyon Business School explains, the central question is to find an optimal allocation of the scarce interconnection capacity between the … [Read more...]
Financing Europe’s cross-border Interconnectors to deliver energy security, lower prices: a look at incentives and policies
The EU and its Member States are building out interconnectors to improve security of supply and affordability of electricity through the physical and economic linking of national energy markets into a single, synchronised European market. But each interconnector is expensive, complex and therefore risky. They can span long distances or natural obstacles such as mountains or seas. Significant network planning and adaptation is needed to account … [Read more...]
Eleclink: what can be learned from this innovative private European interconnector?
Europe has put in place a specific regime to incentivise private investors to build, own and operate new interconnectors. Jean-Baptiste Vaujour at the Emlyon Business School looks at Eleclink, a private interconnector built to connect the UK with France. It uses the existing Channel Tunnel infrastructure. But the most disruptive side of Eleclink is not its smart use of the tunnel but its innovate business and regulatory model. The 1,000 MW DC … [Read more...]
Building and financing the expansion of Europe’s electrical interconnection market
In the first of a series of four articles covering the expanding market for electrical interconnections in Europe, Jean-Baptiste Vaujour at the Emlyon Business School sets the scene by presenting the main points and current developments around the difficulties of building and financing these assets. Interconnectors allow power to be sent across borders to meet the shortfall where supply is not meeting demand. For example, European electricity … [Read more...]
Investing billions in new cross-border Electricity Transmission capacity can cover its costs within a few years
The huge divergence of electricity prices between nations after the energy crises of 2021 and 2022 exposed Europe’s pressing need to increase cross-border transmission capacity, explain George Dimopoulos, Conall Heussaff and Georg Zachmann at Bruegel. Without it, generation costs will be higher, emissions too, and new generation will continue to be badly congested. The author’s calculations reveal that one additional MW of cross-border capacity … [Read more...]
What does cutting-edge Smart Metering look like as Grids become increasingly complex?
The global growth in electrification means grids everywhere are facing new opportunities as well as big challenges. Intermittent renewables, distributed energy generation, and the need to use every kWh as efficiently as possible means Distribution System Operators (DSO), in particular, must deploy optimisation solutions, and fast. Gridspertise provides state-of-the-art solutions for the digital transformation of electricity distribution networks. … [Read more...]
EU now has 9,000+ “energy communities”: smart, decentralised, flexible generation and consumption
The goal of the EU’s “Clean Energy for all Europeans package” (CEP), adopted in 2019, is to improve the functioning and design of Europe’s energy markets and systems. Luca Arfini, writing for ESCI, explains how, as part of the CEP, new market actors called “active customers/consumers and citizens” and “energy communities” are being established. As variable renewable generation grows, the whole system needs to be more decentralised, smarter and … [Read more...]
China can learn from the EU about power market design and infrastructure build-out
How will China integrate its growing Variable Renewable Energy generation and create a nationwide energy system that avoids the risks of curtailment, stranded assets and blackouts? A good place to start is to learn from Europe. Helen Farrell at ECECP summarises their report that uses the European experience to model scenarios for China. China’s key challenges is that its power market lacks an effective auxiliary service market, a capacity market, … [Read more...]
1,500GW of Renewables deployment delayed globally because Grids aren’t modernising fast enough
A first-of-its-kind global country-by-country study, “Electricity Grids and Secure Energy Transitions” by the IEA finds that electricity grids are not keeping pace with the rapid growth of clean energy technologies. Without greater policy attention and investment, shortfalls in the reach and quality of grid infrastructure puts at risk our climate goals. Worldwide, we need to add or replace 80m kms of power lines by 2040 – an amount equal to the … [Read more...]
Make EV batteries bidirectional, get GWs of storage for the Grid
How to cope with the hourly, daily and seasonal variation in demand as regions electrify more, depend more on variable renewables like wind and solar, and cut baseload fossil generation? Storage shifts load nicely. But why build grid-scale batteries when millions of little batteries in our EVs are sitting idle in our driveways for most of the time? As Mark Specht at the Union of Concerned Scientists explains, it’s why in California a bill is … [Read more...]
