Cybersecurity continues to grow in importance for solar asset owners. While increasingly sophisticated attacks target our sector, regulators are not standing idle. This April, the European Commission moved to cut funding for solar projects it deems insecure. In parallel, the implementation of NIS2 gives regulators powerful new enforcement tools that can lead non-compliant players to bankruptcy. In this article, Uri Sadot, managing director of SolarDefend and chair of the Digitalisation Workstream at SolarPower Europe, provides an explanation of where those risks sit, and what action asset owners must take. In recent years, renewable energy has moved from being “additional infrastructure” to being “critical infrastructure”. This happened because renewables reached a critical mass. Last June, solar energy alone became the main source of electricity in Europe for the first time ever. As reliance on solar assets grows, the focus at a policy level now shifts from how much energy is produced, to how reliably it can be depended upon. This shift is creating new regulatory challenges around how to ensure this new infrastructure class is secured from cyber attacks. At the same time, it is
