The energy sector experiences an unprecedented digital transformation upsetting its activities and business models. The convergence of the global industrial system with the power of advanced computing and analytics reveals untapped opportunities at every step of the energy value chain. However, the introduction of digital components in old and unprotected industrial equipments also exposes the energy industry to the cyber risk. The 2015 cyber attack on the Ukraine power grid, which deprived about 200 000 people of electricity for a few hours in the middle of the winter, is one of the most compelling example of the type of threat the industry is facing. This extremely well coordinated cyber attack makes the issue of likely intentional threats to energy systems both substantial and urgent to tackle. In that respect, the protection against malicious attacks has become a key concern for the European Union. This Energy Breakfast Roundtable will deal with the vulnerabilities of the European energy industry and the role of the EU in alleviating the risks.
