Major Donors

The establishment of CSEI was made possible by several major donors from the energy sector, but we are open to additional donors and will in the future establish a stakeholder programme, which makes it possible to join CSEI also in more flexible terms.

Copenhagen Infrastructure Partners

Copenhagen Infrastructure Partners P/S (CIP) is a fund management company focused on energy infrastructure including offshore wind, onshore wind, solar PV, biomass and waste-to-energy, transmission and distribution, and other energy assets. CIP is headquartered in Copenhagen and has 75 employees. The company was founded in 2012 by senior executives from the energy industry in cooperation with PensionDanmark. Today, CIP manages four funds and works in close cooperation with international institutional investors to drive the development of the global energy infrastructure.


GASCADE operates a Germany-wide long-distance gas pipeline network of about 2,400 kilometers in length connecting Germany directly to Poland, the Czech Republic, Belgium, and the Netherlands. The company’s activities are centered around providing transparent, customer-friendly access to this transport system. Located at the heart of Europe and connected not only to the major transit lines from Russia and the North Sea but also to the European natural-gas trading points, GASCADE’S infrastructure has become a hub for European gas transport.


Siemens is a global powerhouse focusing on the areas of electrification, automation and digitalization, helping to pioneer a sustainable future across the globe. Being one of the world’s largest producers of energy-efficient, resource-saving technologies, Siemens is a leading supplier of systems for power generation and transmission as well as medical diagnosis and efficient application of electrical energy. In infrastructure and industry solutions, the company plays a pioneering role. With a history spanning more than 170 years, Siemens today employs around 377,000 people in more than 200 countries/regions.


GD4S is a European association between the leading natural gas distributors in France, Italy, Ireland, Spain, Portugal and Romania. Together, they represent 27.4 million customers in Europe (around 20% of the European market). GD4S is committed to safely distributing natural and renewable gas to consumers. GD4S believes that natural gas is a sustainable alternative fuel for transport, biomethane makes natural gas renewable and the already existing and highly flexible gas networks are immediately available to distribute and store renewable energies. GD4S is therefore committed in raising the voice of Gas-only DSOs in the European Debate, providing expertise with regards to decarbonisation policies, contributing to the development of Gas Market Design and unlocking the potential of renewable gas and gas grids.


GRTgaz owns and operates the longest high-pressure natural gas transmission network in Europe. It is involved in the management of networks in Germany. In Europe and worldwide, it provides assessment and consulting services in the field of gas transmission.

TSO Consortium

TenneT, Statnett and Energinet participate jointly in the Copenhagen School of Energy Infrastructure. The three companies are transmission system operators (TSOs) with responsibility for secure and reliable operation of the electricity grids in their areas. Energinet is also responsible for the transmission of gas in Denmark. The TSOs are working together with CSEI to help meet the challenges of a future decarbonised energy system. See more:,,

Rambøll Fonden

Rambøll Fonden (Ramboll Foundation) was established in 1972 by the founders of Ramboll. Børge Johannes Rambøll and Johan Georg Hannemann and three other partners. It was their wish to ensure long-term existence of the company for the benefit of the Ramboll Group employees. The Ramboll Foundation is the main owner of Ramboll Group A/S.

Fraunhofer Cluster of Integrated Energy Systems

In 2020 CSEI has concluded an agreement with the Fraunhofer Cluster of Excellence Integrated Energy Systems (CINES) to foster cooperation between the two entities. The "Integrated Energy Systems" research cluster (CINES) is carried by the joint vision of transforming Fraunhofer into the lead research institution for applied energy research. As such, the cluster addresses the central technical and economic challenges of the next phase of the global energy transition: the system and market integration of high shares of variable renewable energy sources into the energy system.
