Schneider Electric, Siemens, and Ameresco Are the Leading Energy Service Companies

Top companies are innovating technology & financing options for comprehensive energy management, infrastructure upgrades, decarbonization, and other customer needs

May 21, 2020

A new Leaderboard Report from Guidehouse Insights evaluates the Strategy and Execution of 10 energy service companies (ESCOs), with Schneider Electric, Siemens, and Ameresco ranked as the leading market players.

ESCOs are facing increased pressure to respond to changing consumer expectations and the competitive landscape associated with emerging turnkey energy as a service (EaaS) offerings. These market forces are widening the gap between ESCO market leaders and other companies as some ESCOs innovate in beyond efficiency solutions while others play catch-up in terms of developing comprehensive, integrated technology and financing capabilities. Click to tweet: According to a new Leaderboard report from @WeAreGHInsights, Schneider Electric, Siemens, and Ameresco are the leading ESCOs.

“These companies are innovating technology and financing options within and outside of energy savings performance contract (ESPC) structures to address growing customer interest in comprehensive energy management, infrastructure upgrades, decarbonization, and other beyond energy efficiency solutions,” says Sasha Wedekind, research analyst with Guidehouse Insights. “While traditional ESPCs are not expected to go away anytime soon, it will be harder for ESCOs that do not evolve to meet new customer expectations and trends to maintain market share and achieve growth.”

According to the report, the ESCO market is highly mature. Most players in the market offer robust capabilities across HVAC, mechanical equipment, building envelope, building automation, water, and a variety of renewable technologies, such as solar, wind, and biomass in addition to energy storage, microgrids, and other DER solutions. Many market participants are highly skilled at managing risk and have historically offered comparable capabilities serving a traditional set of customers, such as educational institutions and local governments.

The report, Guidehouse Insights Leaderboard: Energy Service Companies, ranks 10 leading ESCO market incumbents on their ability to innovate and increase technology and financing options available to clients, through ESPCs and other contracting mechanisms. Guidehouse Insights uses a proprietary Leaderboard methodology to profile, rate, and rank ESCOs with the goal of providing an objective assessment of their relative strengths and weaknesses in the ESCO market. These players are rated on 10 criteria: vision; go-to-market strategy; partnerships; technology; geographic reach; sales, marketing, and distribution; depth of ESCO offerings; project portfolio; financing; and staying power. An executive summary of the report is available for free download on the Guidehouse Insights website.
