The urgency of climate change calls for accelerated decarbonization of the electrical grid. An important strategy involves electrification of space heaters, water heaters, and vehicles. If not managed carefully, electrification at scale can result in an unintended consequence of increased electricity loads on the grid not in alignment with the timing of renewable energy supply, or even worsen the load at peak times, making the grid less reliable and more expensive. In addition to electrification of building loads, many other end uses can be flexible such as pool pumps, cooling, and refrigeration. By unlocking load flexibility, new and existing loads may be managed through automated electricity price and greenhouse gas signals in a way to make our grid more reliable, affordable and cleaner.
