The OER System Reliability Procurement Solar DG Pilot Project

OER is spearheading a pilot to understand how renewable distributed generation—in particular, solar power—could potentially reduce the need for costly investments in utility infrastructure to meet growing energy demand.

Energy efficiency and renewable energy provide a suite of well-known energy, economic, and environmental benefits, including the potential for significant cost savings for consumers and businesses who reduce or avoid their on-site energy use.  What is not yet fully understood is how these clean energy technologies can potentially produce additional savings by deferring (or possibly eliminating) the need for investment in costly utility infrastructure to meet growing energy demand.

In 2014, OER and National Grid commissioned a study by Peregrine Energy Group, Inc. to explore how distributed renewable energy—specifically solar—could play a role in Rhode Island’s system reliability efforts. The goal of the study was to better understand the viability, costs, and benefits for solar distributed generation (DG) to reduce peak loads on the electric distribution system, possibly leading to distribution investment deferral.

The Peregrine study considered Rhode Island’s current System Reliability Procurement pilot in the towns of Tiverton and Little Compton and developed: (1) solar deployment options and a proposed configuration for a portfolio of solar DG to meet 250 kW of summer peak load reduction; and (2) an implementation strategy to solicit participation in a pilot and deploy the DG resources.
