Data centres influence how climate goals are met in Denmark.


A number of data centres are planned or are currently under construction in Denmark, and the Danish Energy Agency expects them to have a combined electricity usage of 7TWh, corresponding to about 17% of the national electricity usage in 2030.


With the energy deal from 2018, the Danish parliament passed a deal which shows the way to reach a share of renewable energy of about 55% in 2030. The expected electricity usage of the data centres influences how big a need for expansion with renewable energy there is, in order for the 55% goal to be met.


Ea Energy Analyses has aided the Climate Council in an analysis of large data centres in Denmark, and how their electricity usage will influence the goal of at least 55% renewable energy in Denmark in 2030. Ea concluded that there will be a need for greater expansion of offshore wind parks to reach the goal.


The analyses were carried out with the market model Balmorel, which can optimise operations and investments in the electricity and district heating sector under various conditions. Furthermore, the consequences for the security of supply were analysed with the SISYFOS model, which was developed by the Danish Energy Agency and Ea Energy Analyses.


The analysis and background reports can be found on the Climate Council’s website (in Danish).







New report from the IEA Wind Task 26

Ea Energy Analyses has contributed to a new report published by the IEA Wind Task 26.


The International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 26—The Cost of Wind Energy represents an international collaboration dedicated to exploring the past, present, and future cost of wind energy. The countries included in this report and currently represented by participating organizations in IEA Wind TCP Task 26 are Denmark, Germany, Ireland, Norway, Sweden, the European Union, and the United States.


This report discusses trends from 2008 through 2016 that affected the cost of land-based wind energy in each country. Ea Energy Analyses has written the chapter about Denmark.

New Task 32 report – The future role of Thermal Biomass Power in renewable energy systems.


Ea Energy Analyses has written a new report about the future role of thermal biomass power in renewable energy systems, which has been published by Task 32 under IEA Bioenergy. The report can be downloaded from the Task 32 website here.


In countries where wind and solar energy play a dominant role in the transition to renewable energy sources, a challenge arises as these sources at times generate when the demand is low. Bioenergy, being a dispatchable form of renewable generation, can therefore play a key role as a stabilizing element in a green energy system dominated by variable renewable energy.


The report gives a projection of the European energy system through a study of a thermal-dominated area, exemplified by Germany. The role of biomass technologies towards 2040 is analysed in two scenarios by use of the Balmorel model.


The study concludes that the existing prices and conditions will not facilitate a larger role for thermal bioenergy in Germany, and subsequently Europe. For this to happen, changes in the framework, such as lower prices on biomass and higher CO2 prices, are necessary.

New report – Thermal Biomass Gasification in Denmark
Ea Energy Analyses has drawn up a report on thermal biomass gasification in Denmark, which has just been published by Task 33 under IEA Bioenergy.


The World Bank declared Denmark as the ‘leader in green energy’ in 2017, based on energy efficiency, sustainable energy and access to energy. Danish aims and policies of phasing out fossil fuels have created good circumstances for the development of technologies in sustainable energy, including thermal gasification of biomass and waste.


In the report ‘Thermal Biomass Gasification in Denmark’ (which can be downloaded here), Ea Energy Analyses provides an overview of current stakeholders, development activities and implementations within thermal gasification of biomass in Denmark. The report has been partially financed by EUDP.






China Renewable Energy Outlook 2018
The China Renewable Energy Outlook 2018 provides a status on the Chinese energy transition and updated scenarios for the decarbonization of energy in China towards 2050. The report was launched at the end of 2018 at several events, including a joint seminar with the International Energy Agency in Beijing in November and at the Chinese pavilion at COP 24 in Katowice in December.

China Renewable Energy Outlook is published annually as a part of the five-year program ‘Boosting Renewable Energy as a part of China’s Energy Revolution’ – a multilateral effort led by the China National Renewable Energy Centre. The work is supported by the Children’s Investment Fund foundation and the Danish and German governments.

Ea Energy Analyses has contributed substantially to the report as well as the previous outlooks. Read more about the project here.






Launch of Lombok Energy Outlook
A few weeks ago, the Danish Energy Agency officially published the Lombok Energy Outlook, an analysis carried out by Ea Energy Analyses on the Indonesian island, located in the province of West Nusa Tenggara, close to the island of Bali.

In the analysis, it is underlined how renewable energy can compete with fossil fuels and supply 58% of the electricity consumption at no extra cost, in case current subsidies to coal and gas are removed.


The topic has also been featured in an article in EnergyWatch

EAducation: Introduction to Balmorel for the Danish Energy Agency
Last week Ea Energy Analyses carried out a 5-days course of the power system model Balmorel with a focus on energy planning and analysis of the power sector in developing countries. The participants, 11 advisors from the International Cooperation department at the Danish Energy Agency, got certified as Balmorel Analyst and Operator Level 1.

The enthusiasm and feedback have been overwhelmingly positive.





Intelligent buildings in a smart energy system
Sweco and Ea Energy Analysis have on behalf of the Danish Energy Agency prepared an assessment of the potential for building contribution to flexibility in the electricity and heating system. The analysis concludes that there is the greatest socioeconomic value and profitability when changing the supply form, such as switching from natural gas and district heating to electricity via hybrid heat pump when electricity prices are low. In addition, the analysis points out the importance of consumer tariffs reflecting real marginal transmission and distribution costs in order to mobilize the flexibility potential.

Read the analysis "Energieffektive og intelligente bygninger i et smart energisystem" (Danish), where the potential for different flexibility measures and the profitability of exploiting these potentials is assessed.






Denmark takes over the management of Task 32 with lead from Ea Energy Analysis
With the IEA Bioenergy Task 32, the International Energy Agency has a unique forum for discussion and knowledge sharing about the development of biomass combustion and co-firing which is widely used in Denmark and the other member states and is an important tool for achieving the greenhouse gas emission reduction targets. The cooperation consists of 12 member states whose representatives gather at semi-annual business meetings and associated workshops, where solutions to current technical topics are discussed.

The purpose of the Danish participation in the group is to disseminate Danish policies and solutions, as well as results from Danish RDD activities and projects on biomass combustion and plants, as well as gathering knowledge about the corresponding activities and markets in other countries and disseminating them to the Danish network. Denmark has been in Task 32 for over 20 years.

Task 32 has been led by the Netherlands for many years. From 2019 Denmark will take over the management with Morten Tony Hansen from Ea Energy Analysis as lead, in collaboration with national Energy Technology Development and Demonstration Programme (EUDP). The work consists of realising the group's work program, i.e. in that meetings and workshops are held and reported, that there is progress in the projects and that the results are disseminated.

The work program for 2019-2021 has been under development in 2017-18. Activities concentrate on:


  • Improvement of small scale biomass combustion units such as stoves and boilers in terms of efficiency and emissions and performance in real-life operation
  • Integration of efficient and fuel-flexible biomass power in energy systems
  • Biomass-based high temperature heat for industrial processes
  • Project collaboration with other working groups in IEA Bioenergy


Ea Energy Analysis represents Denmark in IEA Bioenergy Task 32 and leads the group until the end of 2021. Ea Energy Analysis also represents Denmark in IEA Bioenergy Task 33, which deals with gasification of biomass and waste.
