Maybe not directly, but it can be useful with a buffer. The most obvious buffer would be batteries, e.g. installing a PowerWall on a building; but there are a whole bunch of more direct use-cases, which may be more efficient. For example, we wouldn't want unpredictable/unstable bursts of heating and cooling for buildings; but it would be very useful for a heat source/sink, which a building's heating/cooling can use https://en.wikipedia.org/wiki/Ice_storage_air_conditioning https://en.wikipedia.org/wiki/Ice_storage_air_conditioning Likewise, batteries which will be used on a known schefule don't need to be charged as quickly as possible (which is the current assumption for most charging). For example, we can slow/delay charging of commercial vehicles in case prices go down. Datacentres can also spin up machines in seconds to take advantage of lower energy costs. Cloud providers like AWS allow resources to be auctioned off, e.g. we can put latency-insensitive tasks (backups, indexing, report generation, etc.) in a queue until resource costs drop below $X/minute (if it lingers for too long we can either re-insert with a higher threshold, or cancel and process at normal price).
