The Large Commercial Program is an energy efficiency program that offers financial incentives for the implementation and verification of natural gas-saving technologies. The program supports a comprehensive list of upgrades and provides technical assistance and financing options.

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
• Measures 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
• Assistance with application preparation
• Coordination of installation and verification

You will receive coordinated support throughout the process to help your project move forward efficiently and meet Program requirements.

How to apply

To start an application, follow these steps:

• Contact the Program team to schedule an initial consultation and confirm eligibility
• Complete a site assessment to evaluate your facility and identify energy-saving opportunities
• Work with the Program team to develop your project scope and savings estimates

• Install approved measures and complete project verification

For complex projects, additional steps may include feasibility studies and development of project-specific measurement and verification plans.

Available rebates

Financial incentives are provided for eligible projects that reduce natural gas use through energy efficiency improvements.

Incentives are determined based on project type, savings methodology, and verified energy savings. All incentives are subject to program requirements, documentation, and approval processes.

Notice to participants

All projects are subject to Program rules, verification, and quality assurance requirements.

Inspection and review activities may include documentation review, remote verification, and on-site inspection.

If discrepancies are identified, corrective actions may be required prior to approval, and incentive amounts may be adjusted as needed.
