You can get a thermostat that turns the temperature up and down for you at times you choose. Turning the temp down a couple of degrees during the day will save quite a bit. Some here have suggested turning off the water heater until 20 minutes before a shower. Shutting it off at night and then back on in the morning would save also. You might be able to find something that does it automatically.
My electric company lets me average my bill out over the year so every month is the same. They also have a plan that charges different amounts during the day. You pick the plan that works best for you. It wouldn't work for me but it might for you. Check with your company.

You can get foam plates that go in the electrical outlets to block cold air from the outside.
Heat is lost through windows so cover them with plastic during the cold months. Also, increasing the thickness of insulation in the roof/attic will help.
