The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand during the rapid growth of wind and solar power in California. Grid operators must balance supply and demand to maintain a stable electric system. … [continued]
Rising penetrations of variable renewable energy (VRE) in power systems are expected to increase curtailment — the reduction of renewable energy delivered due to oversupply or lack of system flexibility. But while curtailment may be the new normal in the evolving grid, and can even be managed in a way … [continued]
Last weekend, some UK EV owners were paid to charge their cars during a period when the price of renewable energy turned negative.
According to the Union of Concerned Scientists, curtailment of renewable energy is not a problem, it is an opportunity to adjust our use of electricity to a 21st century world.
In a recent article, we found that curtailment of renewables may be cheaper than grid scale energy storage. Sometimes, the simplest solution is the best solution. However, given the complexity of electrical grids around the world, we should also look at all of the available solutions to make sure we … [continued]
On March 16, California set a new all time record for solar energy production. Between grid scale solar and behind the meter solar, as much as 16 megawatts of solar electricity was available just before 3 pm on that day.
China’s power system continues to face numerous problems, including a national power market which in 2016 was oversupplied by 35%, and massive curtailment issues throughout the country’s northern regions, forcing renewable energy and the country’s significant coal industry to compete for dispatch.
China’s National Energy Administration was proud of announcing it had installed 18.6 GW of solar PV in 2015, but new research suggests that not all of that figure was actually connected to the grid. New research from IHS shows that at least 4.5 GW of the total 18.6 GW worth … [continued]
Debunking the clean energy myth that excess generation of wind or solar generation must be curtailed or stored
China’s total cumulative solar capacity has surpassed 50 GW, after the country’s National Energy Administration revealed that the first quarter saw 7.14 GW of new solar capacity added. According to figures released by China’s National Energy Administration (NEA), the first quarter of 2016 saw the country’s solar industry add 7.14 GW … [continued]
