In a bold move, the European Commission announced a ban on funding for solar technology manufactured in China on May 4, 2023, due to rising concerns over potential security threats that could impact energy networks in Europe. This decision mirrors the growing unease in Brussels about the increasing dependence on Chinese green technology.
The ban specifically targets solar inverters, which are considered the "brain" of the solar energy system. These devices, which convert solar energy into usable electricity, are internet-connected and can be accessed remotely for maintenance and software updates, raising fears about their potential exploitation by hackers or hostile entities.
Details of the Announcement
Christophe Boudewijns, Secretary General of the European Solar Manufacturing Council, reported that all inverter companies have what is known as a "kill switch," which is typically used for safety or grid stability purposes. However, cybersecurity experts warn that these remote communications could be exploited in worst-case scenarios to disrupt electricity supplies.
In 2024, Europe imported approximately 61% of its solar inverters from China, according to research group Loom, highlighting the continent's reliance on this technology. Chinese companies such as Huawei and Sungrow dominate the European and global market, having supplied equipment for over 220 gigawatts of installed solar capacity in Europe.
Background & Context
This move comes at a time when Europe is reassessing its dependence on Chinese imports of clean technology. According to Loom, China accounts for 98% of the solar panels and 88% of the lithium-ion batteries imported into Europe. The organization has warned that remote access functionalities in connected energy technologies could create potential vulnerabilities in energy systems.
In March, the European Commission introduced the "Industry Accelerator" law, aimed at directing more funding towards green technology manufactured in Europe, including batteries and electric vehicles. A review of the cybersecurity law was also proposed, granting Brussels greater authority to restrict Chinese companies from critical infrastructure such as communications or energy supplies across EU member states.
Impact & Consequences
Under the new measures, European funds directly managed by the Commission and institutions like the European Bank for Reconstruction and Development can no longer be used to purchase solar inverters manufactured in China. However, these restrictions do not apply to purchases made directly by member states, and installed Chinese inverters across Europe may remain operational.
Estimates suggest that 80% of new solar energy systems in Europe rely on Chinese inverters. If demand shifts away from Chinese suppliers, European companies will need to fill a significant gap. However, Boudewijns believes that European suppliers are prepared for this challenge.
Regional Significance
These developments are particularly significant for the Arab region, where many countries are seeking to enhance their use of renewable energy. European concerns about reliance on Chinese technology may influence Arab nations' strategies in importing clean technology, prompting them to bolster local production or seek safer alternatives.
In conclusion, the European Commission's decision represents an important step towards enhancing cybersecurity in the energy sector and reflects the challenges faced by nations in confronting reliance on foreign technology. Arab countries should take these lessons into account in their efforts towards transitioning to renewable energy.
