• Provide technical services and customer support within various electric utility conservation programs.
• Provide project oversight to ensure progress and high‑quality deliverables are on time.
• Interface with electric utilities, water/wastewater utilities, design consultants, and the regulatory community as needed to support SEM participant progress.
• Identify and engage water/wastewater facilities as potential participants in incentive programs; identify opportunities to generate additional work from current clients.
