MILLBRAE, Calif. — Stem, a provider of energy optimization combining cloud analytics and intelligent energy storage to reduce commercial building electricity costs, announced its first customer deployment at two InterContinental hotels in San Francisco: the InterContinental Mark Hopkins in Nob Hill, and the InterContinental San Francisco in SoMa.

Stem said its system leverages the company’s proprietary combination of big data, predictive analytics, and energy storage to intelligently switch between grid power and battery power to reduce energy costs. According to Stem, the system offers an automatic, real-time decision making engine that dynamically stores energy from the grid and discharges energy into building operations to create maximum energy savings for customers. The system is powered by Stem’s cloud software and advanced power electronics working together to operate CODA Energy’s lithium-ion battery core.

“At the InterContinental Mark Hopkins and InterContinental San Francisco, we have already benefitted from traditional energy conservation and efficiency measures, and are excited about Stem’s ability to deliver even smarter energy use without compromising the comfort of our guests,” said Harry Hobbs, area director of engineering for both InterContinental Mark Hopkins and InterContinental San Francisco. “Stem’s technology is a great fit because it goes beyond energy efficiency to look for other ways to reduce our electricity bills, delivering immediate bottom-line value while at the same time reducing our carbon footprint.”

Stem’s system runs on large amounts of data, including historical weather information and industry vertical usage patterns. Customers benefit from the system’s analytical insights into past, present, and projected future energy use to guide operational decisions.

“The InterContinental, a truly globally recognized brand, is an ideal customer to deploy our technology,” said Salim Khan, CEO of Stem. “World-class luxury hotels have specific requirements around the comfort expected by guests in their buildings. We are pleased that Stem is able to provide the energy insight and optimization they need without affecting the first-class guest experience.”

“We are delighted to have the InterContinental Hotels of San Francisco as our first installed customer and we look forward to a great relationship with the InterContinental for years to come,” said Brian Thompson, founder of Stem.
