Harnessing
Flexibility from
Hot and Cold

A

AS HAS BEEN OFTEN REPORTED, ELECTRICITY SYSTEMS
with high levels of variable wind and solar power generation would benefit from demand flexibility. What is not as often mentioned is that electrification of the transport and heat sectors could exacerbate the need
for flexibility, if they are implemented as inflexible loads. This demand
could also be made more flexible, but it comes with a cost. The main
issue is to identify the cases in which the benefits will outweigh those
costs, a matter that will naturally depend on the evolution of specific
energy systems. In this article, we
lay out some generic principles
and characteristics related to heatsector flexibility and demonstrate
its possibilities using specific
examples. While we generally
use the word heat here, most of
the discussions also apply to cool,
which, after all, is just another
form of temperature difference.
A major potential for flexibility in the heat sector results from the low cost of storing heat, which
allows opportunities to shift electricity demand. Another possibility is
to utilize hybrid systems in which either electricity or fuel can be used
to produce heat depending on price variations between the two options.
