Celtic Energy’s mission is to help our clients achieve their energy goals and minimize risk through our work as the nation’s most effective independent ESPC & PACE Third-Party Consultant and Sustainability Project Manager, while acting as a trusted advisor and educator on all energy-related topics.

How do we bring value to a client’s energy project?

  • Ensure You Get What You Pay For – Several CEI staff are former Director-level ESCO employees, so we know ESCO pricing and we ensure that our clients understand how much they are paying through an “open book” cost buildup.
  • Enhance Your Energy Savings – We have overseen energy projects across the U.S. and can use our best-practices knowledge to help clients reduce their energy costs.
  • Maximize Your ROI – Our ability to discover potential pitfalls early in a project minimizes client risk and maximizes return on investment.
