The share of renewable generation in Europe’s power system is rising fast, but interconnection is not keeping up. Join us on May 19, 2020 to discuss this and related issues. More wind and solar makes the supply of electricity much more dependent on the weather. Nobody wants to build capacity only to switch it off when there’s too much heading onto the local grid. This could put an extra strain on delivering the Green Deal. One solution is to … [Read more...]
Accelerate EV infra, buildings refits to use electricity’s looming spare capacity
How do we turn the pandemic downturn into an executable opportunity, above and beyond targets and promises? Chris Nelder at RMI presents data on how electricity load has dropped during the lockdown in the U.S. That load will return when the economy recovers. In the interim capacity will go unused. New capacity in the pipeline could be delayed. Nelder suggests policy makers grasp the opportunity to fill that gap and use that capacity by directing … [Read more...]
Nuclear fusion: public-private pitch for pilot power plant in U.S.
A working nuclear fusion plant has long been a dream of scientists. The “Sun in a box” would generate abundant low carbon energy with little waste and more safely than traditional existing nuclear (fission) plants. But the scientific, engineering and materials challenges are admittedly enormous. Meanwhile, other electricity generating technologies are getting cheaper, so will we ever need it? Nevertheless, a public-private collaboration in the … [Read more...]
Will China build more Coal to stimulate the economy?
Could China ramp up coal generation – of the order of hundreds of GW by 2030 - as part of its efforts to stimulate its economy and recover from the coronavirus slump? The thinking is that building a coal plant converts faster into economic growth than the equivalent spent on renewables. In the previous decade, building coal plants was an effective part of China’s economic growth plan that secured its place as the world’s second largest economy. … [Read more...]
Utilities can help their central banks, “loaning” electricity during the slump
The coronavirus slump is forcing governments around the world to inject large amounts of cash into the hands of consumers and businesses, until this is all over. In the U.S. it’s $2tn. Catherine Wolfram at the Haas School of Business suggests a way to cut that bill, easing the pressure on central bankers. Utilities (electricity, water, gas) should allow customers to defer payment (instead of using valuable bailout money to pay the utilities). The … [Read more...]
How do we accelerate EU decarbonisation now?
The economic stimulus needed to overcome the current pandemic requires significant resources. But it comes at a time when we need to accelerate the energy transition, which is currently part of the European Green Deal and will also require an increase in resources. Andrei Marcu at ERCSTÂ examines how the transition will be funded, what are the sources of funding and how they relate to and will be impacted by the current health situation. A range … [Read more...]
The value of PPAs during economic turmoil
IEEFA says that the global economic slump being caused by the coronavirus pandemic can show how Power Purchase Agreements (PPAs) protect you against uncertainty. PPAs are long term contracts and prices agreed with energy suppliers. Renewable energy PPAs are one of the best ways big customers in the private sector can support the transition, guaranteeing suppliers income over the long term. Particularly for electricity-intensive sectors, renewable … [Read more...]
China’s 2019 electricity generation reviewed as its next 5-year plan is drafted
Simon Göss breaks down the totals and additions for electricity generation in China. In 2019 the total reached 7,325 TWh (more than twice Europe’s) after adding 330 TWh (more than half Germany’s total). Of that 330 TWh, 120 TWh came from thermal (90%+ coal). But the numbers were dominated by renewables (hydro, wind, solar) which added almost 160 TWh. Though that’s the third year of declining renewables additions, wind and solar curtailment is … [Read more...]
Grid Battery tech on track. It now needs re-designed markets, monetisation
The rapid expansion of variable renewable electricity generation is making cost effective storage more urgent. Sure enough, in Europe several electricity storage projects are under construction and new ones are announced almost on a weekly basis. The battery technology seems to be on track, with estimates of $156/kWh in 2019 dropping to $61/kWh by 2030. But progress is hampered by the lack of a market that recognises and rewards the true value of … [Read more...]
Multi-energy “island” Microgrids can increase grid resilience
As the number of different technologies producing power and providing storage increases, the grid is getting complicated. The best way to make it resilient against outages is therefore changing. The traditional way is to shut down the failing plant, leaving the rest of the grid to cope as best as it can with the change in voltage and frequency. Xi Zhang at the Energy Futures Lab, Imperial College, describes the research looking at multi-energy … [Read more...]
Don’t blame Wind, Solar for Coal cycling. It’s everyday variable demand
Joseph Daniel at the Union of Concerned Scientists explains why variable renewables like wind and solar are not forcing coal plants to cycle (ramp up and down). He presents data from the U.S. that clearly shows it’s straightforward variable demand that’s doing it, because demand has always varied considerably throughout the day. So stop blaming the arrival and growth of wind and solar for this “inefficiency”, he says. These renewables have plenty … [Read more...]
Pumped Thermal Electricity Storage: grid-scale, cheap materials, known tech, compact, install anywhere
We need to store the huge quantities of excess electricity generated by variable renewables. But what’s the best way? Currently, over 99% of large-scale electricity storage uses pumped hydro dams. But geography severely limits where you can build one. And the growth of grid-scale batteries is limited by raw material costs and short lifecycles. Antoine Koen and Pau Farres Antunez at Cambridge University review an important alternative, Pumped … [Read more...]
What if Germany wasn’t shutting down Nuclear? Modelling Coal, Gas, Renewables, emissions, prices
Germany plans to shut down its entire nuclear fleet by 2022. Right now, of the original 17, only 7 are still running. The Fukushima nuclear accident in Japan of 2011 was the trigger for Germany’s abandonment of emissions-free nuclear as part of its clean energy goals. Maximilian Auffhammer at the Energy Institute at Haas reviews a paper by his colleagues that has modelled the whole-system effects of the shutdowns, then compared the results with a … [Read more...]
Poland’s PGE: profits from Renewables can replace declining Coal’s
Poland’s PGE is one of Europe’s most fossil fuel intensive energy firms. Coal makes up around 90% of its electricity generation. It’s been investing around PLN 28bn ($7.2bn, €7bn) to build three new coal power plant units, acquire the Polish coal assets of France’s EDF, and upgrade its existing fleet to meet air quality standards. But a new and detailed report from IEEFA warns that the profitability of these investments will decline in the 2020s … [Read more...]
Even cycling Coal is losing money. Only “summer” coal makes sense in Texas, Louisiana
Joseph Daniel at the Union of Concerned Scientists says a detailed look at the U.S. data shows the days of coal plants being the baseload kings are numbered. The declining costs of wind, solar and gas are making coal look expensive. What’s more, increasing energy efficiency is flattening peak demand (and therefore prices), squeezing those periods when coal could rely on finding customers. That means coal plant owners that say they deserve support … [Read more...]
