>Using a model that’s been called “transformative” for the energy market, the Community Power Coalition of New Hampshire announced this week its initial electricity rate will be 15.8 cents per kilowatt-hour, representing a 20 to 40 percent savings compared to the state’s utility companies.

It's unfortunate that the rate is on the high side, but it's probably just from bad luck with the timing of when they negotiated the contracts. The power market has been extremely volatile lately.

There's no mention of how long the rate is locked in for, but 15.8 cents per kWh is higher than the lowest rates offered by some competitive suppliers.

One plus going with community power is that you don't need to be as vigilant about monitoring contract renewal terms compared to signing up with a for-profit competitive supplier. If you go with a for-profit provider, you're likely to get slammed into a super expensive month to month rate if you forget to renegotiate your plan when it expires. You won't have to worry that if you sign up for a community power rate.
