The Large Commercial Sector (LCS) Program offers no-cost services to help commercial facilities meet energy efficiency goals by determining opportunities for their potential energy savings and prioritizing projects according to their capital plans.

Eligibility requirements

The LCS Program serves large commercial facilities located in the SoCalGas service territory. These customers must be classified as commercial customers, have an active SoCalGas account, and use at least 50,000 therms annually.

Program participation requirements

Customers participate in the Program by working through a structured process from initial screening through project completion and verification.

• Projects must result in measurable reductions in natural gas consumption
• Eligibility improvements can include equipment, controls, or operational changes
• Savings are determined through Deemed, Custom, or Normalized Metered Energy Consumption (NMEC) methodologies

Projects are evaluated under one of the following pathways:

Each project is first evaluated for NMEC eligibility. If NMEC is not appropriate, Custom or Deemed methodologies are used.

All projects are subject to documentation review, installation verification, and savings validation prior to final approval.

Objectives

Other general Program objectives include:

• Supporting identification and implementation of equipment and operational improvements
• Improving customer engagement through end-to-end support
• Ensuring accurate and consistent measurement and verification of energy savings

Program benefits

The Program is designed to reduce the effort required to complete energy efficiency projects and support successful outcomes.

Services include:

• Initial consultation and eligibility screening
• Site assessments to evaluate existing equipment and operations
• Identification of energy-saving opportunities
• Development of project scope and savings estimates
