Overview
Romande Énergie Holding is the holding company of the Romande Énergie Group, a Swiss energy business headquartered in Morges in the canton of Vaud. The group combines electricity generation, grid distribution, electricity sales, and energy services, with its principal operating footprint in French-speaking Switzerland. Its activities are rooted in the development of regional hydroelectric infrastructure and the long-term role of public authorities in supplying electricity to households, businesses, and municipalities. The present group emerged from the 1997 merger of Société romande d'électricité, founded in 1904, and Compagnie vaudoise d'électricité, whose institutional origins reach back to the Compagnie vaudoise des Forces motrices des lacs de Joux et de l'Orbe, established in 1901. The merger placed the combined business under the umbrella of the former Compagnie vaudoise d'électricité. That holding company adopted the name Romande Énergie Holding in 2006. Romande Énergie operates through several principal entities. Romande Énergie SA is responsible for electricity production and distribution; Romande Énergie Commerce SA markets electricity to end customers; and Romande Énergie Services SA provides energy-related services. The broader group has also held interests in renewable-energy, engineering, and energy-service companies in Switzerland and France. The holding company is publicly listed, while the Canton of Vaud and Vaud municipalities have historically retained a controlling public position. An arrangement among the canton, municipalities, and Banque Cantonale Vaudoise was intended to help preserve majority public ownership. The company’s generation portfolio has historically emphasized renewable sources. It has operated or participated in hydroelectric plants, small hydro installations, solar photovoltaic facilities, biomass plants, district-heating facilities, and wind projects. Important assets include the Les Clées plant on the Orbe River, the Farettes plant in Aigle, the Enerbois dry-biomass plant in Rueyres, and the Agrogaz fermentable-biomass plant in Lignerolle. The group has also explored additional wind, solar, geothermal, and other low-carbon production opportunities. Its distribution business has included thousands of transformer stations, substations, and approximately 10,000 kilometres of power lines, most of which were underground according to the cited 2017 description. Through Romande Énergie Commerce, the group supplied roughly 2.5 billion kilowatt-hours annually to more than 300,000 private, commercial, and municipal customers in nearly 300 municipalities in 2017. Following the opening of the Swiss electricity market for large customers, the sales business also served eligible customers beyond its traditional regional area. Romande Énergie has positioned renewable electricity and regional energy supply as central parts of its offering. Its products have included contracts identifying the source and geographical origin of electricity, including Swiss, French-speaking Swiss, renewable, hydroelectric, and locally generated solar options. The group has also participated in smart-grid initiatives and supported technological projects such as photovoltaic glazing. Its historical development reflects the transition of a regional hydroelectric utility into an integrated energy group combining infrastructure, retail, distributed generation, and energy services.
History
Romande Énergie’s institutional history begins with late nineteenth-century electrification projects in the Vaud region. Société électrique Vevey-Montreux was founded in 1886 to supply power for the developing electric tramway connection between Vevey and Montreux. Its Taulan plant initially served transport needs and soon supplied public lighting in Vevey and Montreux. A second plant near Sonzier followed as demand increased. In 1895, a separate company, Société des forces motrices de la Grande-Eau, was established in Aigle and developed hydroelectric resources associated with the Grande Eau and Lac de Taney. The two companies became Société romande d'électricité on 3 January 1904. The new enterprise expanded generation infrastructure in the Aigle area and improved existing facilities at Vouvry and Taulan. Its development formed one of the main institutional foundations of the modern Romande Énergie group. A second important lineage came from the Compagnie vaudoise des Forces motrices des lacs de Joux et de l'Orbe. Created by a 1901 decree of the Grand Council of Vaud, the company was charged both with regulating water levels in the Joux and Brenet lakes and with using those waters for electricity generation and distribution. The La Dernier plant entered service in 1903, followed by the Montcherand-sur-Orbe plant in 1908. By the late 1920s, the two facilities were distributing tens of millions of kilowatt-hours across much of Vaud and into part of Neuchâtel. Winter electricity shortages during the Second World War highlighted the importance of water management. In response to low rainfall in 1942, consumption restrictions were imposed and the company developed pumping infrastructure to move water between Lac de Joux and Lac Brenet. In 1954, the company adopted the name Compagnie vaudoise d'électricité. A renewed concession supported construction of the Les Clées plant, an underground facility below Lignerolle that entered service in 1955 and replaced an older installation. Merger discussions between Société romande d'électricité and the Compagnie de Joux had begun as early as 1917, although the initial attempt failed. The companies later became shareholders in Énergie Ouest Suisse, founded in 1919 to coordinate the use of regional hydraulic resources. A more direct rapprochement occurred in the 1990s. Société romande d'électricité encountered serious financial difficulties associated with real-estate transactions involving its subsidiary Taulan SA. On 14 October 1993, Compagnie vaudoise d'électricité became the majority shareholder, and the businesses were subsequently managed through the CVE-SRE Group. On 24 June 1997, shareholders approved a merger under the name Romande Énergie SA, with Compagnie vaudoise d'électricité serving as the umbrella company. At formation, the Canton of Vaud held approximately 40 percent, Vaud municipalities approximately 30 percent, and private shareholders the remaining 30 percent, reflecting the established public-ownership framework. The holding company changed its name to Romande Énergie Holding in 2006. The group expanded beyond traditional hydroelectric generation through solar, biomass, district heating, small hydro, and wind projects. It acquired or modernized several small plants, including the Brent facility, and carried out substantial work at Farettes. In 2008, it separated its public-transport activities from the energy group; the Vevey-Montreux-Chillon-Villeneuve network was transferred to a specially created company owned by the municipalities it served. By the period described in the cited 2017 material, Romande Énergie had become an integrated regional utility. It operated electricity networks, sold power through Romande Énergie Commerce, supplied more than 300,000 end customers, and maintained a portfolio of renewable production assets. It also participated in smart-grid initiatives and energy-service businesses. Its strategic direction emphasized expanding renewable generation while retaining the regional and publicly influenced character of its electricity infrastructure.
