Optimization is one of Helen’s tools to achieve 100 percent carbon neutrality in its energy production. Valmet’s delivery includes a Valmet DNA District Heat Manager, a district heat production and network optimization solution, which enables the management of district heat production, consumption and transfer through a single solution.

At the same time, the system will enable building an effective demand response management in the future. The system, the value of which has not been disclosed, will be started up in spring 2021

The optimization system that predicts transmission delays and temperatures will improve the energy efficiency of the whole district heating network as it can be used in a more optimal way. This change in our operating model will reduce energy procurement costs and consequently emissions, said Miika Lindholm, Group Leader, Helen.

The system optimizes the temperature of the district heating network flow, pressure differences, and pumping, and coordinates the capacity of heating plants and district heat accumulators. It also automates the operations of district heating networks and plants. Valmet DNA District Heat Manager is part of the Valmet Industrial Internet solutions portfolio.

Our delivery to Helen is based on over 300 successful optimization projects over the past 30 years. Valmet’s best expertise is used to improve the efficiency of the customer’s district heat production in an environmentally friendly way. The new optimization system will be integrated into Helen’s existing production planning system supplied by Valmet, Valmet DNA automation systems and other existing process control and information systems, said Teijo Salonpää, Head of Industrial Internet, Automation, Valmet.
