A technology in operation. Two lines of development.

Tessart addresses a concrete need: supplying heat when it is needed, from energy that is not always available at the same moment.

The need

Heat is going electric. The grid has its busy hours.

Electrifying heat for processes and buildings adds electrical demand, often at the same hours.

Thermal storage makes it possible to charge at one time and deliver heat at another. It makes electrification easier to integrate, for the site and for the grid.

Operating proof

15 MWh in operation. In Valleyfield, since 2025.

The technology is in service. A TESSA installation is operated at an industrial site, under real conditions.

Two lines of development

Industrial and residential. Two markets, one principle.

Industrial

Next steps

What we are working on. In qualitative terms.

  1. Commercial development

    Carry out more project analyses with industrial sites and their engineering firms.

  2. New applications

    Extend integration to other forms of heat delivery, at the pace of the projects assessed.

  3. Residential line

    Continue developing StoQ, in forced air and hydronic versions, through to validated technical data sheets.

These directions are qualitative. They are neither an offer of securities nor a promise of return.
