California has avoided more heatwave-driven rolling blackouts so far this week via energy conservation, demand response, backup power and batteries. Could this be a lesson in meeting long-term grid reliability challenges as clean energy grows in scale?https://bit.ly/3haRWJi

We see air source heat pumps reducing summer peak. Though of course ground source would do more (but at what cost is the question). The question for NY is what % of homes newly get AC w/ a heat pump... guaranteed to add load. Heat Pump Data:http://t.ly/Fz0Q
Air source heat pumps are either no more efficient than "air conditioners," or somewhat less efficient. An air conditioner is an ASHP that only provides cooling. If installing ASHP does reduce peak, it is only because you are replacing old devices with new ones.

A new efficient heat pump is almost always a lot more efficient than the old crappy one it replaces. Hence load goes down. If you don't have an AC and you install a heat pump you will always add load.
