About the company
Green Generation Solutions LLC, a Bethesda, Maryland-based limited liability company, holds a $3 billion Energy Savings Performance Contracts IV (ESPC IV) indefinite-delivery contract with the U.S. Army Corps of Engineers' Engineering Support Center Huntsville awarded June 9, 2025, and competes as a prime contractor exclusively — twelve awards across federal sources with zero subcontractor roles. The vendor operates in the civilian federal real-property and energy-efficiency space without SBA set-aside designations, competing full-and-open across a portfolio centered on facility energy savings, building repair and alteration, and engineering services.
Green Generation Solutions LLC derives its customer concentration from the ESPC IV vehicle structure. The Army Corps of Engineers' Engineering Support Center Huntsville accounts for three awards and $4.54 billion in combined potential value — substantially the entire potential-value universe — and reflects the three-award ESPC IV position (one $3 billion IDC ceiling and two delivery orders worth $1.54 billion combined). GSA's Public Buildings Service and Federal Acquisition Service contribute five awards worth $53.8 million, anchored by eight task orders under the GSA Multiple Award Schedule for $16 million combined potential value. The Department of Agriculture Forest Service rounds out the set with two regional facility awards worth $6.9 million. Coverage across the top five customer components spans 100% of combined potential value, but the distribution masks the structural reality: the ESPC IV IDC and its two Army Corps derivative orders represent 98% of the vendor's dollar exposure, while the remaining ten awards (mostly GSA and USDA facility work) represent a diversified but dollar-small secondary base.
Green Generation Solutions LLC's capability framing derives from the NAICS and PSC concentration: nine awards carry Consumer Electronics and Appliances Rental coding (a proxy for energy-efficiency equipment supply and performance-based contracting), three carry Engineering Services, and the PSC set emphasizes repair and alteration of office buildings, professional engineering support, and building maintenance. The ESPC IV scope reflects this directly — the contract enables federal agencies to undertake facility energy-savings initiatives without upfront capital costs or special appropriations, with the vendor serving as a qualified ESPC provider authorized to deliver financing, engineering, installation, and performance guarantees across the federal real-property portfolio. Recent delivery orders under ESPC IV carry a $1,000 ceiling value (a guaranteed-minimum floor rather than a full-scope order), indicating the vehicle's use as a standing offer with task-order pull-through anticipated to begin after the contract's June 2025 award.
Service Contract Inventory data shows modest scale on federal services contracts above the $150,000 threshold: $2.6 million in total invoiced revenue across FY2022–FY2024 (FY2022 $939 thousand, FY2023 $832 thousand, FY2024 $850 thousand), with roughly 0.1 to 0.3 FTEs annually deployed to SCI-reportable contracts. Hourly-rate posture across SCI-reported invoiced work reflects engineering and program-management labor, with median government-paid rates around $2,812.76 per hour and a 90th percentile of $14,811.66 per hour, indicating senior executive and specialized engineering engagement. GSA Multiple Award Schedule labor rates range from $129.22 per hour (Energy Analyst with bachelor's degree and four years' experience) to $445.09 per hour (Principal/Executive with master's degree and fifteen years' experience), with no security-cleared positions offered. Across SCI-reportable prime contracts, subcontractors account for 8% of total contractor hours, with 30 named subs reported across the contract set — a lean delivery model where Green Generation Solutions LLC retains most labor in-house and engages subs for specialized or supplemental tasks rather than as primary delivery partners.
