Dalkia

Former logotype before it became a subsidiary of EDF

Dalkia was originally known as the Compagnie Générale de Chauffe (CGC), founded in 1935.[3] In 1967, Chauffage Service (founded in 1944) merged into CGC.[3] In 1980, CGC was acquired by Compagnie Générale des Eau (CGE, later renamed Vivendi in 1998).[4] CGC merged with Groupe Montenay in 1986 to form Compagnie Générale de Chauffe/Groupe Montenay, which was further merged in 1995 to become the Energy Services division of CGE.[4]

In 1998, the CGE Energy Services division was renamed to Dalkia and continued to be a subsidiary of the newly renamed Vivendi.[4] It signed an agreement with Électricité de France in 2000 to build an international presence and expand its range of services, hence becoming a jointly owned company.[5] Dalkia also bought the Clemessy Group, which specialises in systems for automation, mechanisation and electronics.

Vivendi spun off its environmental division in 2002 called Vivendi Environnement, which was later renamed Veolia Environnement in 2003.[5]

In 2008, Dalkia sold Clemessy and Crystal to Eiffage, an energy and construction company. In 2009, the Mitie Group PLC, a UK holding company that focuses on providing strategic outsourcing and asset management services, bought the facilities management arm of Dalkia UK.[6]

In July 2014, EDF bought the company's French business and Veolia bought its international operations.[7]

The demerger authorized the two groups to continue using the Dalkia brand for 18 months, before handing over the exclusive rights to Dalkia France / EDF.

In this way, the Dalkia brand was used in France by EDF and abroad by Veolia Environment up until January 2018. Since then, it has been operated by EDF exclusively.

Dalkia has now six energy subsidiaries and is expanding in international markets, mainly in the United Kingdom, Poland, the United States and Russia.

Dalkia has been led by chairwoman and CEO Sylvie Jéhanno since 1 January 2017. The company is now based in Saint-André-lez-Lille, France.

The company has invested in the following technologies: cogeneration (generation of both electricity and heat), biomass, solar power (photovoltaic as well as thermal), geothermal and heat source capture from incineration.

In 2017, the company stated its objective of achieving a 50% share of renewable and recovered energies in its energy mix by 2022.

Heating networks powered by renewables are used in cities (by residents, companies, local authorities, etc.) to reduce their CO₂ emissions.

Customers use Dalkia services to optimise energy efficiency, reduce energy consumption and lower energy bills. These services include energy performance contracts and monitoring by connected Dalkia Energy Savings Centers (DESCs).

Operating primarily in France since the demerger of its French and international activities, Dalkia is redeveloping its international business through acquisitions. Dalkia is currently active in eight countries, in which it has acquired several companies that together employ around 2,800 people.

In September 2016, the company acquired Groom Energy Solutions LLC, a U.S.-based company.[9]

In 2017, Sylvie Jéhanno announced that Dalkia would make a strategic priority of international development, aiming for 50% growth outside France by 2022.[10]

In October 2017, the company announced its acquisition of Matex Controls, a Polish SME specialized in climate engineering for industrial and tertiary buildings.

In August 2018, Dalkia expanded its energy services in the US with the acquisition of Aegis Energy Services, specializing in CHP systems.

In 2019, the Dalkia brand is deployed outside of France. In Poland, ZEC Katowice is now called Dalkia Polska Energia and Matex Controls has changed its name to Dalkia Polska Solutions. In the United States, Groom Energy Solutions has been rebranded Dalkia Energy Solutions.[11]
