Micromem Power Line Monitoring Project Update

Toronto, Ontario and New York, New York, April 19, 2023 - Micromem Technologies Inc. (CSE: MRM) (OTCQB: MMTIF) ("Micromem") ("the Company") has made a significant commitment since 2020 to build its expertise and its profile in technology designed for comprehensive, real time electrical power line monitoring.  Micromem personnel have attended multiple industry trade shows dealing with the electricity transmission sector. In 2021 the Company hired two graduate students in mechanical and electrical engineering for a term of 16 months each. Their role was to investigate market conditions and needs in the sector and to evaluate available technologies based in North America and in Europe.  Micromem forged a dialogue and a working relationship with two Canadian-based companies - the first of which is a large utility and the second one is a developer of energy storage technology.

By late 2021, the Company had accumulated relevant experience and insights into competing technologies that serve  this  industry sector.  At that point, Micromem began to develop a proposal for Transelectrica in Romania. The proposal deals with the electrical grid in Romania and how to introduce new technology to modernize and upgrade the operations of the electrical grid in that country.  The Company submitted their proposal in late 2022 and these negotiations are now being finalized.

Regarding the PLM technologies, new hardware will be selected and reviewed by Micromem, together with WING^[^^1]^, Universitatea Petrol SI Gaze Ploiesti (the "University") and Augustine Professionals (the "Partners"). The new technology will be modified by Micromem for use by the Partners. The criteria are that the technology should be ready for field trials and ready to be connected to the new analytics software that is currently being developed.  It is expected that field trials for the new PLM technologies, including online analytics, will begin in Q4 2023.
