In crude terms, 1/2 HP is 0.37 KW. If you run it on a timer for say 25% of the time, that's 2.24 KWH per 24 hour period, or 69 KWH in a 31 day month. If your marginal electric rate is 14 cents/KWH, you add just under $10 to the electric bill. If you ran it continuously, you'd pay almost $40 a month, gain nothing in terms of dock protection, and annoy your neighbors who want to get out on the ice in winter.
