1. Forging a Pathway to a 100%
Renewable Energy Future
Project Introduction
7/26/2018 1

2. What Is 100PercentCT?
 A holistic Town Based planning tool
that:
◦ Benchmarks Energy Use
◦ Quantifies energy conservation potential
◦ Quantifies local energy potential
◦ Offers a grid architecture to support
massively increased renewables
◦ Provides high level economic modeling
◦ And – in the near future – will offer
campaigns and resources to support town
engagement

3. Produce viable, replicable plans for individual towns to transition to
100% renewable energy by 2050. Key steps include:
Project Vision
7/26/2018 3
Let’s “do the math”!
Take
Stock
• Benchmark current energy use for entire town
• Electricity, heating/cooling, transportation
Reduce
• Investments in efficiency and conservation
• Electrification of heating, cooling and transport
Siting
Survey
• Granular analysis of potential for renewables (solar PV)
• Sensitivity to preserving town’s character and farmlands
Re-think
Grid
• Design of local microgrid(s) with generation & storage
• Engage with utilities to test “utility of the future”
If enough towns chart their path to 100% renewable
energy, we will create a grassroots movement to
influence the state’s energy policy.

6. Conserve and Electrify
 Energy-efficient
appliances and devices.
 Modern design
techniques and
technology on new
buildings and energy
retrofits.
 Adoption of renewable
thermal technology (i.e.,
heat pumps) for heating
and cooling.
 Adoption of electric
vehicles.

7. We need to re-think the electric grid
 Current grid was designed
for large, centralized
power plants sending
electricity in one direction
to consumers
 Future grid must handle:
◦ Distributed generation
◦ Multi-directional flows
◦ Intermittency of renewables
◦ Storage
◦ Demand response
◦ Resiliency & security

We are working collaboratively with Eversource and the non-profit
Clean Coalition to develop a Community Microgrid pilot project.

9. Going From Here to There!
Chart Discussion
• The light blue bars are
current energy use for
Electricity, Gas, Transport
• They total to 686 GWH
• The pink bars are the
impact of Heat Pumps
and Electric Vehicles
• The smaller green bar is
renewable energy
sourced locally
• The final bar represents
the renewable energy
sourced through the grid
