Baseline Assessment


Fundamental to the 100PercentCT project is an initial assessment of a town’s energy usage and related characteristics. Of course, when starting a journey or a project, it is good to know your starting point. Moreover, such an assessment yields important insights.

Getting Started

PACE has developed an approach and tools to carry out a baseline assessment of a town’s energy landscape. This review comprises the following steps:

  • A quantitative assessment of the town’s current energy usage.
  • An estimate of usage under the 100% renewable scenario.
  • A “Siting Survey” of how much renewable energy could be generated in town and
  • A qualitative and quantitative review of local building stock, transportation infrastructure and electric grid

  • Current Energy Usage

In our work with towns and cities in Connecticut, we have found it to be instructive to start with a simple calculation of current energy usage from publicly available sources.

These calculations help to answer some basic questions such as:

  • How much energy do we currently consume annually? How much per capita?
  • What is the mix of energy use between:
    • heating, cooling, transportation and electricity?
    • business vs. residential?
    • Electricity vs. natural gas, oil or other fuels?

These calculations draw upon the following data:

  • Aggregate electricity and natural gas consumption from the utilities.
  • From the town grand list, a list of town buildings and registered motor vehicles.

The resources list at the bottom of this page includes a spreadsheet with aggregate electricity and natural gas figures for all towns in Connecticut as well as a data request for procuring the necessary grand list data from the town tax assessor. It also contains an Excel template for performing these calculations based on a range of assumptions (e.g., average heating oil consumption, average vehicle miles driven and miles per gallon, etc.); PACE is ready to assist your town in populating this template and interpreting its results.
