Case Study: Chewonki Foundation achieves energy visibility and reduced consumption with Powerhouse Dynamics (SiteSage)

Managing Complex Energy Systems Chewonki Institute

The Chewonki Foundation, which runs a school campus, summer camps, and an organic farm in Wiscasset, Maine, operates multiple on‑site renewable energy systems but struggled to monitor and manage their performance. After finding basic data loggers complex, costly, and hard to integrate, the campus needed a simple, turn‑key solution to optimize renewable production and reduce energy spending.

Powerhouse Dynamics deployed its SiteSage platform with monitoring units across three campus buildings, giving staff real‑time visibility that uncovered a faulty heat‑pump control board drawing continuous power and increasing oil‑furnace use. SiteSage enabled timely repairs, reduced overall energy consumption, avoided potentially thousands of dollars in excess heating costs and equipment wear, and supported energy‑education efforts via lobby displays—delivering measurable visibility, lower energy use, and operational savings.
