Industrial Energy Service: the partnership model
Reliable heat and steam, cooling and power keep industrial production moving today and make tomorrow’s growth possible.
Owning and managing energy infrastructure in-house is one approach.
Gren offers another way forward: a long-term partnership covering energy supply and the infrastructure behind it through two pathways:
- Existing infrastructure: we acquire energy assets and take long-term responsibility for operating, maintaining, investing in and developing them.
- New infrastructure: we design, finance and build energy systems tailored to the business’s needs and take long-term responsibility for their operation, maintenance and continued development.
Different pathways with the same goal: secure energy supply and infrastructure that can evolve with the business.

Energy infrastructure for your industry
Power
Power generation, substations and transfer lines
Heating and steam
Heat and steam generation, transfer lines
Cooling
Cooling generation, transfer lines
Reliable energy infrastructure helps industrial businesses create the products people rely on every day.
Wood processing
Heat and steam for drying and processing, with opportunities to use production residues as fuel.
Food and beverage
Cooling and heating to support consistent production conditions, product quality and changing capacity needs.
Metals and mining
Power and process heat for energy-intensive operations, with electrical infrastructure tailored to site requirements.
Chemicals and pharmaceuticals
Heating and cooling for demanding process requirements, with clear responsibilities for maintenance and safe operation.
Pulp and paper
Steam, heat and power for continuous production, with opportunities to improve efficiency and recover process heat.
Data centres
Cooling and electrical infrastructure designed around uptime requirements and growing computing capacity.
Other industrial operations
Energy infrastructure tailored to the site’s operating needs, investment plans and future growth.
Supporting changing production needs
New production lines, higher demand and efficiency goals can change what a site needs from its energy infrastructure.
Gren can help expand capacity, modernise assets and improve efficiency. Depending on the site, opportunities can also include recovering excess heat, integrating energy storage or participating in electricity markets.
Each step is assessed and agreed together, shaped around the site’s needs and the business’s plans.
The value of a partnership
Secure energy supply – reliable energy supporting industrial production.
Capital flexibility – opportunities to release capital from existing infrastructure or fund new systems, depending on the partnership structure.
Clear responsibilities – for the full lifecycle of the infrastructure and shared with energy expert, backed by performance guarantees.
Experienced local support – access to technical expertise and energy-market knowledge.
Support for changing needs – capability and investment to develop infrastructure as production requirements evolve.
How we work together
Transparent pricing – clear cost drivers, agreed pricing principles and visibility throughout the partnership.
Clear agreements – scope, responsibilities, governance and decision rights understood by both sides.
Measurable performance – agreed KPIs, regular reporting and transparent follow-up on performance and improvement actions.
Open communication – regular dialogue on performance, priorities and next steps.
Continuous improvement – agreed investments in efficiency, asset renewal and new capacity and technologies.
Partnerships in practice
Process heat for the production of pallet elements and blanks, Lithuania
We turn wood-processing by-products from Juodeliai’s production into process heat for lumber drying. The on-site energy plant supports increased production capacity and can expand as Juodeliai’s future energy needs grow.

Industrial cooling for the dairy industry, Estonia
Gren provides industrial cooling for E-Piim’s Paide dairy complex through a high-efficiency cooling system. Waste heat from the cooling process is recovered for building heating, while Gren takes long-term responsibility for the cooling energy supply.

Heat for malt production, United Kingdom
The biomass plant supplies renewable heat for malt kilning at Muntons’ Bridlington maltings. Using locally sourced woodchip, the solution supports reliable process heat while significantly reducing emissions from the malting process.

Heat, steam and power for plywood production, Estonia
Woodchips from Metsä Wood’s plywood production are used at Gren’s nearby combined heat and power plant. Heat, steam and electricity are supplied back to the mill, connecting production residues with the mill’s energy needs.

Heat and steam for whisky production, United Kingdom
The Wick energy plant supplies heat and steam to the adjacent Old Pulteney Whisky Distillery, supporting production of its malt Scotch whisky. The plant uses sustainably sourced virgin woodchip from the local region and also supplies heat to a district heating network serving 255 residential and commercial customers.

Experience you can build on
Our local teams combine decades of experience operating energy infrastructure with technical expertise, energy-market knowledge and a focus on safety and continuous improvement.
That experience supports day-to-day operations and the investment, maintenance and renewal your infrastructure needs over time.
