Energy price increases

When I first moved here a couple years ago I paid around 10-12 cents per kWh. My current plan (9.5 cents) is expiring and they are offering a 24 month option at 12.5 cents. I went on power to choose and the options are 15 cents for 36 months up to 22 cents per 6-12 months.

Do I suck it up and get an expensive short term plan and hope energy prices drop or do I lock in that 12.5 cent rate for the next two years?
