Possibly...in our area the power company has some type of control unit that they can put on your heat pumps and water heaters where they will turn them off for brief periods of time during peak plant usage to help avoid rolling brown outs. Supposedly they give you a discount if you use the system. I didn't qualify because I don't use much electricity to start with I have my water heater on a timer with a kill switch override. I also am more prone to open windows than use the air conditioning, and keep the heat set in the low 60's. We use the compact fluorescent bulbs in all but 3 fixtures and primarily use task lighting versus whole room lighting.
