Alternative Regulation

In 2006, the Vermont Public Service Board (PSB) approved a new regulatory framework, often called alternative regulation, or "alt-reg," to streamline how your electric rates are established. It also created new incentives for us to improve customer service and become more effective.

The process includes annual filings so the PSB can review our costs and set rates accordingly. To see GMP's plan, click here.

On August 1st, GMP provided its draft base rate filing to the Public Service Board and the Department of Public Service pursuant to its approved Alternative Regulation Plan.  A copy of the draft base rate filing is available at

We believe that this new way of regulating makes a lot of sense. It lowers costs for you and gives us better incentives to perform well for you. We look at this as one more innovative tool that can help us provide you with premier service.
