Sustainable energy solutions — from investment analysis to installation, financing and long-term performance monitoring.

ProStream Group designs and implements renewable energy projects and energy efficiency solutions for municipal, commercial and industrial clients. Through our ESCO model, we offer project financing where clients pay from the energy savings achieved — eliminating upfront investment barriers. We combine 30 years of engineering expertise with dedicated solar, heat pump and energy storage capabilities to deliver measurable CO2 reductions and long-term operational savings.

How do we deliver?

These are the service stages PSG delivers across renewable energy projects:

• Energy audit & investment consultation — Analysis of energy consumption patterns, system sizing, and feasibility assessment
• Project design — Technical project preparation, administrative procedures and permitting documentation
• Equipment supply — Delivery of complete equipment packages (PV modules, inverters, mounting structures, cables, grounding/lightning protection, energy storage systems, heat pumps)
• Installation & construction — Own qualified installation teams for mechanical and electrical works, including own metal construction manufacturing
• Commissioning & start-up — System testing, commissioning and handover
• ESCO project financing — Project financing model where energy savings fund the investment — no upfront capital required from the client
• 24/7 monitoring & O&M — Operational management, real-time PV/system monitoring, fault analysis, timely fault resolution, maintenance and warranties

What do we deliver?

These are the types of renewable energy and efficiency projects PSG delivers:

• Photovoltaic (PV) power plants — Roof-mounted and ground-mounted solar installations, from 30 kW to 800+ kW, for commercial, industrial and public sector buildings
• Energy storage systems — Battery storage solutions integrated with PV installations for energy independence and grid optimization
• Heat pump systems — Air-to-water and water-to-air heat pump installations for residential and commercial buildings, delivering heating/cooling with CO2 emission reduction
• Biogas & CHP (Combined Heat and Power) — Supply, installation and commissioning of co-generation units and biogas systems for waste-to-energy applications
• Hydro power plant reconstruction — Design, dismantling, mechanical and electrical installation, and commissioning of cooling and turbine systems in existing hydro facilities
• LED street lighting & energy efficiency — Large-scale municipal lighting replacement programmes to reduce energy consumption
• Dam & wind turbine IoT monitoring — Remote monitoring networks for hydrotechnical facilities and wind energy assets, tracking vibration, temperature, energy output and weather conditions
