System Oscillation Assessment for IBRs: Moving Towards MIMO Active Frequency Scanning
System Oscillation Assessment for IBRs As the power system continues to transition towards inverter-based resources, assessment of dynamic stability has become increasingly important. One area that requires particular attention is the assessment of system oscillations, commonly known as SSO studies. While SSO describes oscillations below the 50 Hz fundamental, NESO’s assessment scope also considers oscillatory […]

Connections Reform: Why Your Curtailment Forecast May Be Wrong
Connections Reform is reshaping more than grid connection dates. For distribution-connected renewable energy and battery storage projects, changes to the distribution queue and LIFO stack could significantly alter expected curtailment levels. While much of the industry focus has been on Gate 1, Gate 2 and CP2030 outcomes, developers and investors should also consider how post-reform queue reordering may impact project revenues, valuations and financing assumptions.Projects that once appeared low-risk for curtailment could find themselves pushed down the stack, while others may benefit from improved queue positions as less advanced schemes fall away. Understanding where your project sits in the post-reform queue is becoming an essential part of due diligence and project assessment.

CATOs – Competitively Appointed Transmission Owners
The introduction of the Competitively Appointed Transmission Owner (CATO) regime marks a major shift in how transmission infrastructure projects could be delivered across Great Britain. Developed over more than a decade through Ofgem's ITPR and ECIT programmes, the CATO framework aims to introduce competition into the delivery of eligible onshore transmission assets, helping to support the UK's transition to a cleaner, more resilient electricity network. As the first CATO projects move closer to implementation, understanding the regulatory framework, technical requirements, and opportunities for stakeholders has never been more important.

UK AI Growth Zones: Turning Policy into Deliverable Data Centre Projects
The rollout of UK AI Growth Zones (AIGZs) marks a significant shift in how the UK is seeking to deliver the next generation of AI‑enabled data centres. Led by the Department for Science, Innovation and Technology (DSIT), the programme is explicitly designed to remove key delivery constraints by prioritising access to power, streamlined planning, and investment ready locations capable of supporting large‑scale, energy intensive infrastructure.

Why the Strait of Hormuz Crisis Will Reshape the Power & Renewables Industry
The Strait of Hormuz crisis highlights how vulnerable the global power and renewables industry remains to oil supply disruption. Around 20–25% of global seaborne oil passes through this narrow shipping route, meaning geopolitical tensions can quickly impact energy markets, logistics costs, and industrial supply chains.Even as electricity generation shifts towards renewables, oil still underpins transport, petrochemicals, and manufacturing processes used to produce solar panels, battery storage systems, transformers, and power electronics. As a result, oil market volatility can increase project costs, extend equipment lead times, and create uncertainty for renewable energy developers worldwide.

CMP446 Explained
CMP446 raises the TIA threshold from 1MW to 5MW in England and Wales, streamlining grid connections for sub-5MW distributed generation projects. By removing unnecessary transmission impact assessments, CMP446 reduces delays, lowers costs, and creates faster routes to market for developers. But what does this mean for projects already in the pipeline and how will it affect larger schemes? Here’s what developers need to know.

Microgrids, Power-to-X, and Data Centres: Salvaging Value from CP2030 Gate 1 Grid Offers
Receiving a Gate 1 connection offer no longer has to signal the end of a viable energy project. As grid timelines stretch into decades, developers are increasingly turning to behind-the-meter solutions such as Power-to-X, private-wire demand, and data centre co-location to unlock revenue sooner. By rethinking how and where electricity is monetised, Gate 1 projects can reduce risk, improve bankability, and retain strategic optionality while awaiting Gate 2 progression.

All We Want For Christmas Is To Understand the Power Grid
From the quietest demand days of the year to dramatic voltage challenges and the famous New Year’s “midnight surge,” the festive season produces some of the most unusual electricity patterns on the system. As Britain powers down for Christmas and ramps up for the New Year, renewables, flexibility, and smart network management take centre stage. In this festive deep dive, we share curious tales of winter demand, green Christmas miracles, and what they reveal about the future of a decarbonised grid.
