New Generation Projects
Use the map below to see if there is 3-phase power available to a specified address. Enter an address in the 'Find Address' bar nbsp; Zoom into the area of interest. If there is 3 phase available it will appear as a thick green line. This map is based on plant records and does not perfectly represent the presence of energized 3 phase power. It is imperative that the actual availability be confirmed with a Green Mountain Power representative. The lines take a few seconds to paint, please be patient.Read more

Process for starting a new project with GMP
The first step for a new project with GMP is to contact a distribution designer at a local service center. Your distribution designer will be your main contact during the planning stages of your project.Read more
This is a letter from us stating we'll be able to turn the lights on in your new spot.
If you are planning new construction or a commercial addition to an existing facility, you will need what is called “An Ability to Serve” letter. This is a statement that we can supply power from our existing (or if necessary, upgraded) infrastructure.Read more
Service Construction & Relocation
Permanent service will be extended to buildings that are permanent in nature, e.g. houses, manufactured homes, garages, barns, and businesses.
Before you need to have your new service hooked up, make sure you have all of the information you need to keep your project on track. The information contained below is also available in the New Service Checklist.Read more
Green Mountain Power offers online access to the Vermont Utilities Electric Service Requirements Manual free of charge. A voluntary association of electric utilities produced the manual as a guide for constructing electric service facilities. It is available for download below.Read more
Timelines are dependent on the nature of the project and if all of the requirements have been met.
Green Mountain Power will provide you with an estimate, and your local GMP Distribution Designer will provide you with a written estimate. The average cost will vary; however as an example the average single phase overhead is $15 per foot, and the average single phase underground is $16 per foot. Prices are detailed in the Line Extension and Relocation Policy we file with the Public Services Board.
What is more expensive, an overhead installation or underground installation?
In most cases, the GMP estimate is comparable in either instance. However, there may be additional costs with an underground system because of development contractor costs to supply and install conduit.
Handling unexpected costs
GMP will calculate the cost of the job prior to construction. Should there be any changes to the project, the estimate will change accordingly.
If GMP runs into a ledge, a new estimate for additional costs will be provided to the customer.
Temporary service will be installed in instances where permanent structures will not be available, such as construction trailers, road projects or service for contractors for construction purposes. The service term is six (6) months and there is an evaluation fee of $225.
Typically, a temporary service is limited to 6 months.
