Its focus is on developing technologies to improve the energy performance of the company's customers. Through its research into new technologies and performance evaluations of promising options, the LTE meets the need of Hydro-Québec's customers (residential, commercial, institutional and industrial) to become more efficient in the way they consume energy. Its expertise covers the following areas: energy use in buildings, electrotechnologies and processes, integrated energy systems and electrical engineering as applied to energy use. LTE specialists combine technical and scientific know-how with a thorough understanding of customer needs and extensive field experience. The laboratory uses this expertise to innovate and adapt various technologies with private partners to meet new market needs. It can also offer effective support for customers in improving their energy performance. The implementation of mechanical steam compression at Nexans Canada, requiring 10 times less energy than gas-based processes, is one of the many energy-efficiency projects supported by LTE in its ongoing contribution to all sectors of industry. For commercial and institutional customers, a research team is designing a heating apparatus that accumulates heat at times of low consumption and reconstitutes it at peak periods, which helps to reduce the electricity bill. The LTE is also at work developing a diagnostic tool—an interactive questionnaire—designed to help residential customers gain a better understanding of their electricity consumption. The LTE focuses on energy-use technologies, putting technological innovation to work for the company's customers.
