ChatGPT and DALL-E generated image of A panoramic cityscape view showing a variety of buildings with solar panels installed on their rooftops. The buildings range from modern skyscrapers to traditional residential houses, reflecting a diverse urban environment.
Studies started emerging in 2014 demonstrating these capabilities. I first heard about it at WindPower 2014 in Las Vegas. There have been multiple studies about using wind farms for backup, voltage control and frequency control, including a National Resources Canada study run by my friend Tom Levy. Once obvious model is day ahead reserve markets in the USA. Jesse Jenkins did a great study that showed that the USA’s nuclear pressurized water reactor fleet had some ability to offer reserve power at some points in their fueling cycle and lifespan if they were allowed to operate flexibly. Regulatory constraints prevented that. But regulatory constraints typically don’t prevent wind or solar farms from reserving power on high wind and sun forecast days to provide fast response reserve power.
One of the challenges which I expect to see overcome is more regional- and continent-scale grid and transmission planning in developed countries. In the USA, historically it’s been state by state, which means that entrepreneurs like Michael Skelly run into significant roadblocks trying to bring renewable electricity across multiple states, as is documented in the great book
While it does enable some reduction in utility-scale investments, it also creates the infamous duck curve which isn’t necessarily easy to manage with the generation behind the meter. Utility-scale solar farms like wind farms have contracts and controls allowing them to be shut down when they are excess of requirements, but that doesn’t exist nearly as much for panels on Joe Median’s roof.
