What is energy system integration?

Energy system integration refers to the planning and operating of the energy system as a whole, across multiple energy carriers, infrastructures, and consumption sectors. It creates stronger links between them with the objective of delivering low-carbon, reliable and resource-efficient energy services, at the least possible cost for society. Energy system integration is the pathway towards an effective, affordable and deep decarbonisation of the European economy.

The current energy system is still built on parallel and vertical energy value chains, which rigidly link specific energy resources with specific end-use sectors. This model of separate silos cannot deliver a climate neutral economy. It is technically and economically inefficient, and leads to substantial losses in the form of waste heat and low energy efficiency.

The Energy System Integration Strategy sets out a vision on how to accelerate the transition towards a more integrated energy system, in support of clean energy and a climate neutral economy while strengthening energy security, protecting health and the environment, and promoting growth and global industrial leadership.

The Strategy sets out 38 actions to implement the necessary reforms. These include the revision of existing energy legislation, financial support or research and deployment of new technologies and digital tools, guidance to Member States on fiscal measures and phasing out of fossil fuel subsidies, market governance reform and holistic infrastructure planning, and improved information to consumers.

What are the main elements of the strategy?

The strategy is built on three complementary and mutually reinforcing elements:

Finally, the strategy will be pro-consumer, providing clear and easily accessible information on the cleanest solutions and climate-friendly choices in the market, enabling and encouraging smarter and more sustainable energy use. It will rely on an increased use of digitalisation to connect consumers, producers and energy system operators with each other. This will also contribute to the fight against energy poverty.

The strategy lays down concrete policy proposals that the Commission will present over the coming months and years to deliver on these objectives.

Does this strategy help to reach the goals of the European Green Deal?

Yes. Energy production and consumption account for 75% of our greenhouse gas emissions. The energy system is therefore crucial to delivering on the European Green Deals objective of reaching climate neutrality by 2050. The energy system also underpins our economy and our daily lives. It provides jobs and livelihoods and strengthens European competitiveness and innovation.

Energy sector integration enables to combine decarbonised and renewable energy supply with efficient demand side technologies such as electric motors, heat pumps and fuel cells. Deep greenhouse gas emission reductions can only be reached through a combination of energy efficiency and very high shares of renewable energy. And both energy efficiency and renewables penetration can be facilitated by a more integrated energy system.

A new inter-connected system will be more efficient and circular, capturing and re-using waste energy. It will be cleaner, with increased use of heat and electricity produced from renewable sources applied in efficient demand side applications in industry, transport and heating. And for those sectors where electrification is difficult, the strategy proposes steps to promote cleaner fuels, including sustainable biofuels and biogas, and renewable hydrogen.

All this will contribute to combatting climate change and reach the goals of the European Green Deal while keeping the costs of the energy transition under control, thus contributing to a fair and just transition.

Will the strategy help Europes economic recovery from the Covid-19 crisis?

Yes. The strategy will be another building block of the economic recovery in the aftermath of the COVID-19 crisis. The transition to a more integrated energy system is of crucial importance for Europe, now more than ever. The Commissions Next Generation EU recovery plan presented on 27 May 2020 highlights the need to better integrate the energy system, as part of its efforts to unlock investment in key clean technologies and value chains. By relying on greater use of clean and innovative processes and tools, the path towards system integration will also trigger new investments, jobs and growth, and strengthen EU industrial leadership at a global level, contributing to the economic recovery.

Does the strategy continue to support fossil fuels such as gas and coal?

On the contrary, the strategy is a roadmap to accelerate the phasing out of fossil fuels through 3 levels:

As regards to gas, the strategy proposes a pathway to replace natural gas with sustainable renewable gas and new synthetic gases based on renewable sources such as hydrogen and synthetic methane.

Does the strategy contribute to the goal of a just transition?

The objective of the strategy is to reach our climate objectives at the lowest possible cost for consumers and public budgets. The strategy also proposes to reinforce the role of consumers in driving the transition to a decarbonised, decentralised energy system. Providing clear and easily accessible information will enable citizens to make climate-friendly choices, change energy consumption patterns and be informed about the best technology options available to them.

The strategy also takes advantage of the rapidly decreasing costs of renewable energy across the EU, which results in lower prices for the consumers, increased energy security, and a more inclusive energy system. In addition, this strategy aims at strengthening the competitiveness of the European economy by promoting growth and technological innovation across the whole EU.

Does the strategy respect the energy-efficiency-first principle?

Yes. The energy-efficiency-first principle is at the core of energy system integration. Energy efficiency reduces the overall investment needs and costs associated with energy production, infrastructure and use. It also reduces the related land and materials use, and the associated pollution and biodiversity losses.

Energy system integration can help the EU achieve greater energy efficiency through a more circular use of available resources and by switching to more efficient energy technologies. For example, electric vehicles are much more energy efficient than combustion engines. Applying this energy-efficiency-first principle consistently across the whole energy system will be done by giving priority to demand-side solutions whenever they are more cost effective than investments in energy supply infrastructure in meeting policy objectives.

Other measures will ensure that customers decisions to save, switch or share energy properly reflect the life cycle energy use and footprint of the different energy carriers, including extraction, production and reuse or recycling of raw materials, conversion, transformation, transportation and storage of energy, and the growing share of renewables in electricity supply.

How does the strategy support EU leadership in clean energy technology?

The strategy aims to ensure that the EU fully exploits its head-start and expertise in renewable and smart energy technologies. Specific sectors and value chains that are expected to have a central importance and where the EU is well positioned for global leadership include:

How does the strategy affect the EUs security of energy supply?

The EU is currently importing 58% of its energy needs, mostly in the form of oil and gas. With the clean energy transition, the EU will decrease its dependence on fossil fuels and fossil fuel imports. The Energy system integration strategy will facilitate this process. The EU will consume less energy overall, increasingly rely on domestic renewable resources and gradually diversify its energy imports towards cleaner energy carriers, such as renewable hydrogen. These energy savings, diversification and domestic production will help to build a more resilient European economy.
