Hydro-Québec is a government-owned public utility established in 1944 by the Government of Quebec. Based in Montreal, the company oversees generation, transmission and distribution of electricity for all of Quebec.Relying almost exclusively on its sixty hydroelectric generating stations, Hydro-Québec is the largest electricity generator in Canada and the world's largest hydroelectric producer. As of 2011, the combined capacity of its power stations was 35,829 megawatt and its distribution network served 4.11 million customers.The development of several large-scale hydroelectric projects which took place non-stop from the late 1940s to the mid-1990s — the Bersimis, Carillon, Manic-Outardes, Churchill Falls and the two phases of the James Bay Project — allowed Quebec to reduce its reliance on fossil fuels. In 2009, primary electricity accounted for 40.05% of all energy used in the province. However, the construction and operation of these projects has led to conflicts with aboriginal populations living in Quebec's North.Hydro-Québec has played a "nearly mythical role" in Quebec's economic development since its establishment, with its sustained capital investments, by fostering local engineering expertise and by its capacity to generate large quantities of renewable electricity at low prices.The increasing demand for competitively priced renewable electricity fostered by the fight against climate change had a positive impact on Hydro-Québec's balance sheet in the last decade. Between 2008 and 2012, the company paid C$8.9 billion in dividends to its sole shareholder, the Government of Québec, while keeping Quebec retail power rates among the lowest in North America.

Methods, systems, and computer program products for determining severity of a geomagnetic disturbance on a power grid using similarity measures are provided herein. A method includes extracting multiple features of activity associated with geomagnetically induced currents from multiple heterogeneous data streams; comparing the extracted features to historical data related to geomagnetically induced currents to determine a level of similarity between each of the extracted features and the historical data; assigning a level of severity to one or more of the extracted features having a level of similarity with the historical data above a given threshold; and generating a notification comprising (i) a prediction of activity associated with geomagnetically induced currents based on the extracted features having a level of similarity with the historical data above the given threshold, and (ii) the level of severity assigned thereto.

A method and a system for continuously in-line annealing a forwarding ferromagnetic amorphous alloy ribbon in a curved shape to improve its magnetic properties without causing the ribbon to become brittle and which operates at significant high ribbon feeding rates. The amorphous alloy ribbon is fed forward, tensioned and guided along a path at a preset feeding rate and is heated at a point along the path at a rate greater than 10^(3) C./sec to a temperature to initiate a thermal treatment. Then the ribbon is initially cooled at a rate greater than 10^(3) C./sec until the thermal treatment ends. During the thermal treatment, a series of mechanical constraints is applied on the ribbon until the amorphous alloy ribbon adopts a specific shape at rest after the thermal treatment is ended. After the initial cooling, the amorphous alloy ribbon is subsequently cooled at a sufficient rate to a temperature that will preserve the specific shape.

EELICON is concerned with an innovative switchable light transmittance technology developed previously in projects co-funded by the EU Framework Programmes. The core of this development are mechanically flexible and light-weight electrochromic (EC) film devices based on a conductive polymer nanocomposite technology with a unique property profile far beyond the current state-of-the art, opening the possibility to retrofit existing windows with a electrically dimmable plastic film. According to life cycle assessment studies, considerable energy savings may result when such films are included in appliance doors, automotive sunroofs, and architectural glazing, and the comfort is significantly enhanced. The development has been driven to the pilot-line production stage, however, the decisive step from research to innovation could not yet be accomplished for a number of technical and economic reasons. To overcome this gap, EELICON will tackle existing drawbacks by removing equipment limitations, automating processes, and establishing a high-throughput prototype production for a cost-effective high performance EC film technology in Europe. The ambitious goal will be approached by joining efforts of European and overseas players to integrate nanotechnology, materials, and production know-how, i.e., specific expertise of European SMEs. Relevant IP is available for exploitation. The project comprises a pilot-line, a validation, and a prototyping phase (incl. business planning) and fully complies with the objectives of NMP Activity 4.4 Integration and call NMP.2013.4.0-3 - From research to innovation: Previously obtained research results are used by industry, the European paradox is relieved, valley of death is overcome by following three pillars of development eventually resulting in creation of new businesses in Europe. The project is characterised by strong industrial/SME participation. 8 out of 13 partners are industrials, 6 of which being SMEs with leading roles.

A method for preparing a ceramic from an inorganic base material in the form of a powder with a high boiling point, including a step in which the powder of the inorganic base material is mixed with a second inorganic component which is also in powder form and which serves as a dopant for the inorganic base material. The dopant comprises a single inorganic material or a mixture of at least two inorganic materials that have a dopant effect on the inorganic base material. The method also includes a sintering step performed at a high temperature. Owing to the high density thereof, the resulting ceramics are suitable for use as a target element. The films and electrodes obtained from said ceramics have particularly beneficial properties.
