The P2H facility ranks among the most powerful of its kind in Austria’s industrial sector and helps stabilize the electricity system by converting surplus renewable energy into usable process heat.

The facility is primarily deployed during periods when wind and solar generation place a heavy load on the grid and electricity prices fall. In such situations, it can ramp up within a very short time, absorb renewable power, and feed it directly into the site’s heat network. This relieves pressure on the Austrian power grid, reduces curtailment of renewable electricity generation, and simultaneously enhances security of supply at the Lenzing site. Its flexible operation allows Lenzing to make economically optimal use of low‑cost renewable energy. At the same time, fuels – including fossil energy sources – can be replaced and CO₂ emissions effectively reduced.

“The new power‑to‑heat facility demonstrates how industrial decarbonization can be implemented in practice – technologically sophisticated, economically viable, and with a clear positive impact on the site,” says Georg Kasperkovitz, member of the Managing Board of the Lenzing Group.

The project was implemented through close cooperation between Lenzing and VERBUND. Lenzing was responsible for the technical design, construction, and full integration of the facility into the site’s energy and heat management system. VERBUND contributed its expertise in infrastructure, energy marketing, and market operations, integrates the facility into Austria’s balancing energy market, and ensures its optimal deployment within the power system. In addition, VERBUND has been implementing renewable energy projects at the Lenzing site for several years, including photovoltaic installations and EV charging infrastructure, thereby supporting a holistic approach to industrial decarbonization.

“Our partnership with Lenzing clearly demonstrates the potential that lies in close collaboration between industry and the energy sector. By integrating the power‑to‑heat facility into the balancing energy market, industrial processes become an active part of a flexible energy system. Solutions like this are essential to making optimal use of renewable energy while sustainably strengthening security of supply,” emphasizes Michael Strugl, Chairman of the Executive Board of VERBUND AG.

With the commissioning of the 14‑MW power‑to‑heat facility, Lenzing unlocks additional potential for climate‑friendly, future‑oriented production. The new installation increases flexibility in energy use, strengthens heat management, enables efficient utilization of renewable energy, and makes a significant contribution to the industrial heat transition and the long‑term implementation of climate‑neutral production pathways.
