***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids aren’t ready to integrate them. As … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany can’t agree
France and Germany lead the camps in disagreeing on the future of nuclear in Europe. Camille Lafrance and Benjamin Wehrmann at CLEW take a deep dive into the reasons why, quoting experts and politicians. Germany’s vision of a fully renewables-based EU is at odds with France’s unwavering support for low-carbon nuclear energy. European-wide agreement on targets matter because they drive future investment in the targeted technologies and the design … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
Wind (and Solar) need their own Financial Transmission Rights to hedge their unique congestion risks
Financial Transmission Rights (FTRs) help generators and load-serving entities hedge congestion-related risk. Transmission congestion causes a divergence between wholesale power prices where it is generated and the trading hubs where it is delivered and sold. Because the congestion, and therefore the risk, varies over time it is particularly important to variable renewables. That uncertainty increases investor risk which potentially slows … [Read more...]
Manifesto: fit-for-purpose flexible grids for the clean electrification of Europe
The integration of new clean generation sources on top of the increase in electrification of industry, e-mobility, and heating and cooling means grid investment must be made a priority. Anything else will leave deployment-ready solutions waiting, slowing down the transition. The backdrop is that over one third of the EU’s grids are already more than 40 years old. Eurelectric has produced a manifesto, “Connecting The Dots”, that estimates … [Read more...]
Do e-bike subsidies lift sales, change habits and cut emissions?
What happened when Sweden introduced a 25% rebate on the cost of an e-bike for 12 months over 2017-18? Lucas Davis at the Haas School of Business reviews a study that digs into the consequences. Sales increased by 70%. E-bike prices remained steady, so the sellers didn’t simply raise prices to eat up the rebate. The study estimates that although a third of those sales would have “happened anyway” (i.e. no additionality) the remaining two-thirds … [Read more...]
New research ranks the 12 best ways to cut car use in cities
Behaviour change is as an important part of our transition journey as the clean energy revolution. Kimberly Nicholas at Lund University summarises research that has gathered together nearly 800 peer-reviewed reports and case studies from across Europe that analyse ways of reducing car use. One main challenge is to quantify the benefits so policy-makers and citizens can make evidence-based decisions on how to re-imagine city mobility. Nicholas … [Read more...]
Industry’s large on-site batteries can profitably help stabilise the grid
Energy-intensive industries that invest in their own large on-site batteries will provide multiple benefits to themselves as well as to grid stability, says a new study by the Joint Institute for Strategic Energy (JISEA) in partnership with NREL and others. It matters because future power systems will need to be highly flexible due to the variability of wind and solar. The study assessed two established energy-intensive industries (chlor-alkali … [Read more...]
How to keep Wind and Solar profitable as its electricity gets cheaper
Success can cause problems. As wind and solar penetration increases the electricity it generates gets cheaper. If it stops being profitable we’ll stop building it, thus endangering our emissions-free goals. Dev Millstein at the Lawrence Berkeley National Laboratory summarises their research paper that looks at how market value changed over time at 2,100 utility-scale power plants across major power markets in the U.S., using 2019 data. It’s clear … [Read more...]
