Maximizing Energy Efficiency
ENGIE strives to enhance energy efficiency by providing high-performance solutions in the various sectors of energy production and use. From this point of view, innovative technological developments are just as important as adopting ecologically responsible approaches on all levels of the energy chain.
Production plants: the technical challenges of energy production
ENGIE takes care to use the most advanced technologies in order to open high energy production plants.
- The Maxima plant at Lelystad (Netherlands). The plant consists of two ultra-modern gas turbine units, each with a capacity of 435 MW. Capable of producing enough electricity to power some 1.6 million homes, both units are of the latest generation and offer a very high yield approaching 60%, all while having a very limited impact on the environment.
- The Heron II plant (Greece). Commissioned in December 2010, Heron II is a combined cycle gas plant owned jointly by ENGIE and GEK TERNA. In its class, it is currently the most modern and the most efficient in the country, with a yield of 58% versus the national average of 54%.
Energy consumption in buildings: one of the 21st century’s largest areas for improvement
Around 41% of the total energy demand goes to the residential and service sectors. This particularly heavy usage led the ENGIE Group to commit to reducing energy consumption in buildings.
- Energy performance in Alsace high schools
Partnering with the Caisse des Dépôts and the Fonds d’Investissement et de Développement des Partenariats Publics Privés – Fidepp (a fund for investment and development in public-private partnerships), ENGIE Cofely is responsible for the energy efficiency of 14 high schools in the Alsace region. The project includes reducing the buildings’ energy consumption and greenhouse gas emissions. The 20-year contract should see the energy consumption of the buildings, which have a total area of 300,000 m2, reduced by 35% and their greenhouse gas emissions by 65%. It includes constructing six biomass boilers, optimisoptimizing the heating and ventilation systems, installing 5,000 m2 of photovoltaic panels, insulating the buildings and replacing wood trim.
- The Manifesto: a commitment to progress published annually
In late 2009, ENGIE signed the “Commitment to Action Manifesto” on the energy efficiency of its office buildings as part of its activities in the World Business Council for Sustainable Development (WBCSD). Since then, the Property Department has taken actions, soon to be published in the Group’s Green Buildings Policy, which will apply to the 2010-2020 period for the Group’s office buildings. In 2010, a survey of the buildings (between four and five million square meters worldwide) was carried out as well as energy audits on 420,000 m2 of floor space – covering approximately 60% of the buildings owned by the Group in France.
The Green IT program or making information technologies sustainable
In 2007, IT accounted for 2% of global CO2 emissions (Gartner).
ENGIE is incorporating the Green IT program into its sustainable development policy. This “Do IT Green!” program presents two goals:
- mitigating the impact of information and communications technologies (ICT) on the environment by promoting more energy-efficient practices (reduction of workspace and data center energy consumption, rational use of printing, waste recycling, etc.)
- positionner l’IT au service des métiers et du Développement Durable en proposant des solutions pour réduire l’empreinte environnementale d’autres secteurs grâce à des technologies innovantes (réunion à distance, dématérialisation, smart metering/smart grid, optimisation de la logistique, etc).
adapting IT to the demands of the businesses and sustainable development by offering solutions for reducing the environmental footprint of other sectors through innovative technologies (video conferencing, going paperless, smart metering / smart grid, logistics optimization, etc. ).
Program initiatives are now structured around four themes: energy efficiency (to reduce IT power consumption and the associated greenhouse gas emissions), recycling, @work (to adopt smart behavior in the workplace) and green business (developing innovative products to reduce the impact of our customers’ activities).
With “Do IT Green!” ENGIE aims to reduce its environmental footprint. In order to support actions for optimizing IT solutions, a campaign was conducted among all employees. Their contribution, in particular through the rational use of IT solutions, is one of the necessary conditions for this program to reach a high level of success.
The “Do IT Green!” program allows ENGIE to capitalize on its best practices in order to set up further relevant actions and move from just local initiatives to a comprehensive approach involving every one of the Group’s entities. In order to find out the IT sector’s carbon footprint and measure the progress of actions undertaken throughout the Green IT program, a study was carried out in 2010 using ADEME’s Bilan Carbone® methodology.
