NB Energy

What NB Energy does

NB Energy (ΝΒ Ενεργειακή) is a privately held Greek engineering and construction firm founded in 1991 and headquartered in Thessaloniki, Greece. The company designs, manufactures, and installs turnkey biomass combustion systems for industrial steam and superheated water production, with power capacity ranging from 2 MW to 20 MW and operating pressures up to 20 bar. Systems utilize locally available agricultural byproducts as feedstock — including peach kernels, rice husks, olive kernels, wood chips, pellets, and sunflower shells — tailored to the specific residues of each client's industry. The company also delivers cogeneration (CHP) systems via steam turbines and Organic Rankine Cycle (ORC) stations, and provides heat recovery modules (economizers) that capture waste heat from flue gases.

The company's offering is built around three core product lines: saturated steam production systems, superheated water production systems (140°C), and combined heat and power systems, complemented by heat recovery add-ons and specialized industrial infrastructure (silos, conveyor lines, biological treatment systems). NB Energy runs a direct B2B enterprise sales motion with a consultative, project-based sales cycle that spans feasibility study, licensing, design, construction, and commissioning, supported by ongoing maintenance, spare parts, and modernization services. Its primary customers are Greek industrial firms in food processing/canning (Del Monte Hellas, KRONOS, PRODROMOS PAYLIDIS, ALEXANDER, VENUS GROWERS, EURIMAC), papermaking (ΠΑΚΟ Koliopoulos, MAKEDONIKI ETARIA CHARTOU, ΧΑΡΤΟΠΟΙΙΑ ΚΟΜΟΤΗΝΗΣ), and construction materials (YTONG). The company partners with German firms MANSFELD ENERGIETECHNIK GmbH and RICHARD KABLITZ & MITTHOF GmbH for specialized components and technology, and claims up to 66% fuel cost savings versus crude oil with 1-3 year ROI for clients.

The business model combines one-time turnkey equipment sales with ongoing professional services revenue (feasibility, licensing, training, maintenance, spare parts, modernization, certification). NB Energy is founder-controlled, with Nikolaos Vagiakos, a Mechanical-Electrical Engineer, serving as President, CEO, and majority shareholder; no external institutional investors are disclosed. Operations are entirely domestic within Greece, with a small team of engineers and approximately 10+ permanent technicians, supported by proprietary facilities in Thessaloniki covering administration, technical design, warehouse, and a fully equipped mechanical workshop.

Core offering

NB Energy designs, constructs, and installs turnkey biomass-fired industrial systems for producing saturated steam, superheated water, and combined heat and power (CHP). Systems operate from 2 MW to 20 MW and use locally available agricultural byproducts (peach kernels, rice husks, olive kernels, wood chips, pellets, sunflower shells) as fuel. The company also provides heat recovery modules, feasibility studies, licensing support, construction, commissioning, and ongoing technical maintenance.

Product overview

NB Energy operates as a biomass energy systems manufacturer offering a portfolio of integrated products and services centered on industrial steam and heat production. The core product line consists of three main systems: saturated steam production systems, combined heat and power (CHP) systems, and superheated water/vapor production systems—all powered by biomass feedstock. These systems are designed for power ranges from 2MW to 20MW with operating pressures up to 20 bar. The portfolio is complemented by heat recovery modules (economizers) that capture waste heat from flue gases, as well as building/installation services and specialized industrial applications including silos, refrigeration, and biological treatment systems. The company provides complete project lifecycle support from feasibility studies and design through construction, licensing, and financing to ongoing technical support and maintenance.
