Project Objectives

The objective of this project is to enable a local energy system in Thamesville to reduce GHG emissions by decreasing energy demand and consumption. To do this, an integrated voltage management system using edge-of-network grid optimization (ENGO) devices was deployed on distribution transformers. These were used in combination with an upstream voltage regulator to achieve conservation voltage reduction (CVR).

Expected Results

This project will result in Entegrus’s ability to better manage distribution system voltages and improve efficiency without compromising power quality. The project will enhance the utilization and extend the operating life of existing utility assets, providing improved grid visibility to respond to and investigate power-quality issues more efficiently.

Project Updates

Project construction was completed April 26, 2019 ahead of schedule and commissioning and tested was started and successfully completed. Data collection has started for the CVR long term test plan and will conclude August 2020. Currently, annual CO2 reduction is approximately 41 tons from energy reduction and approximately 55 tons from demand reduction.
