US DOE 10 CFR 436.33: Federal Solar ESPC Contractor Guide

Key Takeaways

• Title 10 CFR Part 436 Subpart B (§ 436.33) governs procedures for contractor selection in federal Energy Savings Performance Contracts (ESPC).
• Requires federal agencies to procure ESCOs from the Department of Energy's (DOE) qualified contractor list.
• Mandates comprehensive site surveys and investment-grade energy audits prior to project award.
• Enforces binding contractual guarantees that annual energy cost savings meet solicitation percentages.
• Requires written notification to all responding qualified firms upon selection.

Statutory Purpose of 10 CFR Part 436 Subpart B

Under Title 10 of the Code of Federal Regulations, Chapter II (Department of Energy), Subpart B implements federal energy performance contracting authority under the National Energy Conservation Policy Act (NECPA).

Section 436.33 establishes structured competitive procedures allowing federal civilian and military installations to deploy solar photovoltaic and storage systems with zero upfront capital outlay.

ESCO Procurement & Competitive Range Framework

Under Section 436.33, the federal government follows a multi-phase contractor selection method:

Implementing Solar Conservation Measures Under ESPC

To ensure statutory compliance during federal solar procurements:

1. Investment-Grade Verification: The ESCO's engineering proposal must model solar irradiance, shading, degradation, and utility rate tariff structures.
2. Guaranteed Cost Reductions: Annual energy cost savings generated by solar arrays must exceed the agency's annual amortization payments to the contractor.
3. Written Selection Documentation: Contracting officers must record formal competitive rankings and issue formal written award notices.
