This project demonstrates FREE energy’s expertise in integrating renewable energy with conventional diesel generation, delivering intelligent fuel-saving solutions that improve energy efficiency, reduce operating costs, and enhance power reliability for remote industrial facilities and labor camps operating in off-grid or generator-dependent environments. 

Project: Nesma Workshop, Grid-Tied Fuel-Saver Solar Solution
Service: Solar
Location: Dammam, Saudi Arabia
Client: Nesma & Partners
Scope: Engineering, Procurement, and Construction (EPC)
Status: Commissioned 

Nesma & Partners, one of Saudi Arabia’s leading diversified engineering, construction, and contracting groups, engaged FREE energy to design and deliver a grid-tied fuel-saver solar system for its Workshop facility in Dammam, part of a pair of solar deployments the group commissioned across its Dammam operations to reduce reliance on conventional grid and diesel power. 

Fuel-saver solar solutions differ from standard grid-tied systems in that they are purpose-engineered to integrate with a facility’s existing power infrastructure, whether grid-connected, diesel-generated, or hybrid, to displace the highest-cost portion of energy consumption first. The engineering team designed the Nesma Workshop system under this principle, delivering full EPC scope, engineering, procurement, and construction, to integrate a 1.1 MWp solar installation with the facility’s existing electrical distribution and load profile. 

The Workshop system is being delivered alongside a companion 1.6 MWp installation at the neighboring Nesma PMV facility, together representing 2.7 MWp of combined fuel-saver solar capacity across Nesma’s Dammam sites, materially reducing operating costs while strengthening energy resilience for the group. No independently published source describing this specific installation was found; the figures above come from internal project records.

Since commissioning, the system has generated SAR 117,500 in annual cost savings, 652 MWh of clean energy per year, and an estimated 510 tons of CO2 reduction annually for the compound, reflecting the level of executive attention major Saudi real estate developers are now placing on renewable energy integration within premium residential assets. 

This project showcases the team’s capability to deliver high quality, aesthetically considered residential scale solar solutions for premium real estate developments, a growing segment across Saudi Arabia as developers seek to differentiate their communities with tangible sustainability credentials and lower shared service costs for residents. 

Project: Confidential, 2 MWp Rooftop Solar EPC for a Large-Scale Logistics and Distribution Facility
Service: Solar
Location: Riyadh, Saudi Arabia
Client: Confidential, under NDA
Status: Commissioned 

Logistics and distribution facilities are ideal candidates for large scale commercial solar because of their expansive, uninterrupted rooftop areas and consistently high daytime energy loads from cooling, lighting, and material handling equipment. For one such facility in Riyadh, operating under a confidentiality agreement that precludes naming the client, FREE energy was selected to design, install, and commission a 2 MWp rooftop solar PV system across the facility’s substantial warehouse footprint. 

The engineering team approached the project with a focus on maximizing usable rooftop area while accounting for structural loading limits, shading patterns, fire access pathways, and equipment maintenance clearances, the standard technical considerations that define a well engineered commercial rooftop solar EPC project at this scale. High-efficiency PV modules and inverters were selected to guarantee performance over the system’s operating life, with the installation engineered, procured, and constructed under FREE energy’s full EPC scope, from initial system design through final grid-tie commissioning. 

Since commissioning, the 2 MWp system has delivered SAR 592,000 in annual cost savings for the facility, generating 3.29 GWh of clean electricity every year while cutting the site’s carbon footprint by an estimated 2,570 tons of CO2 annually, figures that place this project among the most impactful commercial rooftop solar installations in FREE energy’s Saudi Arabia portfolio. The scale of the savings underscores the strong economics of commercial solar PV for high-consumption logistics and warehouse assets operating under Saudi Arabia’s abundant solar irradiance. 

For commercial real estate owners, logistics operators, and warehouse developers evaluating rooftop solar EPC in Riyadh or across the wider Kingdom, this project stands as a flagship reference for how large scale commercial solar can deliver both meaningful cost savings and measurable carbon footprint reduction, backed by FREE energy’s full service solar design, procurement, and construction capability.

Project: Saudi Aramco, Telecommunications Sites Solar PV Retrofit
Service: Solar
Location: 8 regional sites between Riyadh and Dammam, Saudi Arabia
Client: Saudi Aramco
Status: Completed, September 21, 2025 

Solar assets, like any piece of critical infrastructure, need periodic technical review to keep performing at the level they were originally designed for, particularly across multi-site portfolios where system age, installation quality, and environmental exposure vary considerably from one location to the next. Saudi Aramco engaged ZOMCO x FREE energy to retrofit and optimize the solar photovoltaic systems powering eight of its remote telecommunications sites, spread across two industrial hubs, Riyadh and Dammam. 

The engineering team carried out a full technical audit of each existing solar installation, assessing module degradation, inverter performance, mounting structure integrity, wiring and combiner-box condition, and monitoring system functionality, then replaced outdated modules and supporting components with new equipment to meet current standards. Underperforming components were flagged for replacement or upgrade, restoring each system to, or above, its original rated output across a combined installed capacity of roughly 186 kWp. 

Delivering the retrofit across two major industrial hubs required careful coordination to minimize disruption to Aramco’s ongoing telecommunications operations at each site while restoring full solar generation capacity. The modernization sustains Aramco’s renewable energy commitments at these remote communication sites, ensuring optimal performance, extended system lifespan, and reduced maintenance needs, while reducing reliance on conventional power and enhancing operational resilience across critical communication infrastructure in Saudi Arabia. 

Completed on 21 September 2025, the project reinforced the team’s position as a long-term technical partner to Saudi Aramco, complementing the company’s separate HVAC assessment and cathodic protection solar work carried out for Aramco elsewhere in the Kingdom. The engagement demonstrates capability in solar asset management, PV system retrofit engineering, and multi-site renewable energy optimization for asset owners across Saudi Arabia looking to extend the life and performance of aging or underperforming solar PV systems.
