Grids & Integration

SolarEdge has outlined a transition pathway to integrated 800 V (DC) infrastructure for data centers, arguing that legacy alternating current (AC) systems introduce inefficiencies that could constrain the growth of AI workloads. It says rising compute demand and next-gen NVIDIA GPUs are increasing urgency, while data centers lose an estimated 10% to 30% of input power through multiple conversion stages.

Latest analysis from Ember finds major grid bottlenecks in transmission and distribution networks across Europe, threatening the viability of both future utility-scale and smaller-scale residential solar in the most impacted countries.

Investors at the Battery Business & Development Forum (BBDF) 2026 signaled continued confidence in the energy storage market, while warning that regulatory uncertainty, particularly around grid fees in Germany, could affect project economics and investment decisions.

Due for completion in 2028, the DUB20 data center campus in County Wicklow will feature battery energy storage and solar PV installations capable of generating 6,000 MWh annually. It will be Ireland’s first Green Energy Park, delivered as part of its large energy users action plan (LEAP).

Marine energy is renewable and generally predictable. It could thus compensate for the unplanned intermittency of solar and wind generation, its proponents argue. But several challenges still need to be overcome for the energy to become widely used.

An international research team developed a multi-stage intrusion detection system that uses supervised and unsupervised AI techniques to detect and mitigate cyber threats in smart renewable energy grids. The system can reportedly achieve high accuracy, low false positives, and real-time detection, outperforming traditional intrusion detection system models.

Germany’s Federal Network Agency will use a new, structured framework developed by Fraunhofer IOSB-AST to classify cybersecurity incidents in the energy sector. The methodology enables comprehensive risk assessments, from initial reports to systemic and economic impacts, supporting consistent evaluation across the entire energy value chain.

Accelerating energy transitions in major economies can create positive spillover effects worldwide, even amid geopolitical tensions, with North America and the Eurozone boosting progress in other regions.

Spain’s grid operator Red Eléctrica and regulator CNMC have launched real-time voltage control services, allowing renewable energy installations to provide dynamic grid support under a new regulatory framework.

Researchers found that widely deployed smart meters pose a “massive” cybersecurity risk, potentially enabling data manipulation, energy theft, and service disruption. They propose a new detection method using state estimation and statistical boundaries to more accurately identify cyberattacks, outperforming traditional techniques despite higher computational demands.
