Enhancing Europe’s Grid Stability: Forced oscillation guidance on draft NC RfG 2.0

Enhancing Europe’s Grid Stability: Forced oscillation guidance on draft NC RfG 2.0

Sep 7, 2026 |

The ENTSO-E and WindEurope, jointly released the Technical Group on Forced Oscillations Report, to provide technical guidance on the proposed forced oscillation requirements introduced in the draft NC RfG 2.0. Although the report is non-binding, it is intended to form the technical basis for a future implementation guidance document after the EC formally adopts the revised network code. The report primarily focuses on wind power plants, although future requirements will also apply to other inverter-based power park modules, including solar photovoltaic plants and battery energy storage systems. As Europe moves towards an increasingly inverter-based power system, the report provides a practical framework for managing forced oscillations while highlighting the need for continued research and collaboration.

Sodium-Ion Storage Has Left the Lab, and Entered the Field

Sodium-Ion Storage Has Left the Lab, and Entered the Field

Sep 3, 2026 | ,

Sodium-ion batteries, as a solution for grid-scale storage demands, have spent the better part of a decade described, roughly, as “promising.” It’s a word that’s covered for a lot of unfinished progress and has become somewhat of a warning sign to anyone in this industry trying to separate emerging technologies from commercially ready ones. The technology has moved beyond the stage where the primary questions are whether the chemistry works or whether it can be manufactured at scale. What’s changing quickly right now, though, is sodium-ion is being evaluated against the same practical criteria as other commercial storage technologies: performance, safety, manufacturability, supply-chain resilience, lifecycle economics, and the ability to deploy at meaningful scale.

Why underground hydrogen storage in Europe matters for a low-carbon energy system?

Why underground hydrogen storage in Europe matters for a low-carbon energy system?

Aug 24, 2026 | ,

Europe’s energy system is entering a decisive transformation. Energy storage is therefore increasingly critical. Short-duration options smooth intraday variability and support hourly and daily balancing. But when imbalances last beyond roughly 8–10 hours, direct electricity storage hits technical and economic limits. At that point, only large-scale, long-duration storage can cover overnight, multi-day, or seasonal stress events. Until now, underground gas storage has been the primary source of large-scale system resilience, and it continues to play a critical role. In a low-carbon system, underground hydrogen storage will take over this role, delivering long-duration flexibility with clean molecules.

AI-Based Performance Analysis in Solar Energy Systems: From Monitoring to Fault Detection

AI-Based Performance Analysis in Solar Energy Systems: From Monitoring to Fault Detection

Aug 14, 2026 | ,

Solar energy systems are designed to generate power consistently, but performance can decline due to factors such as soiling, shading, equipment degradation, and inverter issues. These losses do not always trigger immediate alerts and can go unnoticed, gradually reducing output. Operators rely on monitoring systems to track generation and flag major deviations. While these systems provide visibility, they are designed to catch larger failures, not smaller performance losses that develop gradually and often go unreported across systems.

Europe’s Energy Transformation: Data centres, grid stress and new opportunities

Europe’s Energy Transformation: Data centres, grid stress and new opportunities

Jul 13, 2026 |

Data centres are becoming a systemically important electricity demand due to their scale, geographic concentration and fast growth, requiring more active grid management rather than passive absorption. They create challenges because their rapid development often outpaces transmission and generation expansion, and their software-driven, power-electronic behaviour does not always align with existing connection and planning frameworks. This calls for improved demand forecasting, greater transparency on grid capacity, and more coordinated, harmonised connection requirements across Europe, alongside flexible connection arrangements to manage near-term constraints. At the same time, data centres also represent a significant opportunity: their built-in control systems and electrical infrastructure could enable them to provide grid services, support flexibility and contribute to decarbonisation.

Grid-Forming Inverters: Enabling stability in renewable-dominated systems

Grid-Forming Inverters: Enabling stability in renewable-dominated systems

Jul 6, 2026 |

GRID-INDIA has proposed a set of measures to support the adoption of GFM technology in the Indian power system. It is recommended that new BESS installations above 50 MW, particularly in remote or weak-grid areas, incorporate GFM capability. A phased roll-out is suggested, beginning with large pilot projects using BESS-backed GFM inverters. These pilots would provide operational experience and help stakeholders make informed decisions for wider deployment. In parallel, aligning Indian standards with international testing and performance frameworks would help ease the transition. Effective implementation will also require close coordination between technology providers, renewable and storage developers, system operators and regulators.

Renewables Impact: Assessing power system resilience in non-EU Mediterranean countries

Renewables Impact: Assessing power system resilience in non-EU Mediterranean countries

Jun 29, 2026 |

The transition towards higher shares of renewable energy across the assessed Mediterranean countries is expected to significantly increase system flexibility requirements between 2025 and 2030. As renewable deployment accelerates, ramping requirements and periods of negative residual load are expected to intensify, with Tunisia facing the most frequent occurrences, particularly in winter when demand is low and renewable output remains high.  While solar and wind follow relatively predictable daily patterns, electricity demand varies seasonally, with summer demand creating mismatches between supply and consumption. This increases the need for flexible resources such as energy storage, demand response and cross-border interconnectors to balance the system.

Modular approach with RE+BESS for supporting data center growth

Modular approach with RE+BESS for supporting data center growth

Nov 7, 2025 |

Data center development may come in all levels of power consumption. However, because developers rarely build, install, and commission data centers in a single phase, projects of all sizes need a power supply that can grow and expand with them. When covering the incremental energy demand from a new data center, a large new single firm resource is an unwieldy indivisible capital investment. A modular approach with renewables plus batteries reduces risk and provides better economics.
