EirGrid Achieves 75% Variable Renewable Energy Generation Trial on Ireland Power System

Windmills on green land with a small road.

EirGrid, the grid system operator for Ireland, alongside its partner SONI, the system operator for Northern Ireland, recently achieved a major decarbonization milestone by successfully operating Ireland’s electricity grid at between 70% and 75% variable renewable energy (VRE) for a total of 232 hours across an 11-month trial period. This trial demonstrates that up to three quarters of the electricity flowing on the Irish electricity grid at any point in time can now come from VRE sources.

The Ireland and Northern Ireland power system is the first in the world to reach this landmark level of renewable generation while overcoming major technical challenges associated with integrating electricity from wind farms, solar farms, and interconnectors that link it with other countries. There were several new all-island wind energy records set during the 11 months, including the current record of 4,584 megawatts on February 5th.

EirGrid had previously imposed a cap of 70% on the amount of variable renewable generation on the grid at a given time. Following this successful trial, the cap has now been raised to 75%. This trial also marks the culmination of EirGrid and SONI’s 11-year work program focused on progressively increasing the limits of VRE on the Irish grid. Work will now begin on increasing the figure to 95% by 2030 to achieve the government’s renewable energy targets.

Read EirGrid’s full press release: Electricity Grid to Run on 75% Variable Renewable Generation Following Successful Trial.

EirGrid has demonstrated its leadership in system operation by not only raising the bar for what is possible in VRE integration, but also by working with the G-PST as one of its founding system operators and helping provide coordinated support and knowledge transfer for other organizations pursuing clean energy transitions. Mark Foley, EirGrid’s Chief Executive and a prominent advocate for the G-PST, recently expressed in a piece for the Irish Times how collaborative initiatives across the power systems industry are key to successfully addressing climate change.

G-PST/ESIG Webinar Series: Inertia Monitoring

April 2022

As shares of inverter-based resources increase, fewer synchronous generators may be online at any given time. Inertial response available from synchronous machines after a sudden large imbalance on the system is therefore diminishing. Various methods and technologies to improve and supplement inertial response exist and are gradually being deployed in power systems with high shares of inverter-based resources. Regardless of the methods being used, there is a need to improve situational awareness and accurately monitor available inertial response in real-time. A number of methods for estimating and monitoring inertia have been developed over the past few years. This webinar covers the need for inertia monitoring and methods that are currently being used or proposed around the world.

G-PST/ESIG Webinar Series: Project EDGE / DER Marketplace Demonstration

30 March 2022

Project EDGE is an innovative, first of its kind trial demonstrating a proof-of-concept Distributed Energy Resources (DER) Marketplace to inform current and future reforms in line with Australia’s Energy Security Board Post 2025 NEM initiatives.

This collaboration between the Australian Energy Market Operator (AEMO), AusNet Services (AusNet) and Mondo (collectively, the Project Partners), with financial support from the Australian Renewable Energy Agency (ARENA) seeks to understand, test, and demonstrate a proof-of-concept DER Marketplace that enables efficient and secure coordination of aggregated DER to provide wholesale and local network support services within the constraints of the distribution network in a way that promotes the National Electricity Objective (NEO). The primary intent is to identify capabilities that can be replicated at scale across the National Electricity Market (NEM).

This presentation provides an overview of the project, learnings to date and research questions that aim to answer key questions across industry on the customer needs, alignment to the NEOs, wholesale integration capability, local network services requirements, operation within Dynamic Operating Envelopes (DOEs), how to efficiently exchange data at scale, and the roles and responsibilities of each of the actors within the DER Marketplace.

Control Center of the Future Assessment Developed for Peruvian System Operator

Peru’s system operator, Comité de Operación Económica del Sistema Interconectado Nacional (COES), is embarking on a shift to higher wind and solar energy penetrations in its power system. The organization expressed interest in possible recommended investment priorities to adapt to more variable generation, as well as shifting energy demand profiles through electrification and increased growth rates. Under the G-PST’s System Operator Technical Support Pillar (Pillar 2), core team organizations the Electric Power Research Institute (EPRI) and NREL developed an in-depth assessment of the optimal approaches for control center improvement that COES might consider to meet the demands of the future power system.

The vision for the control center of the future outlined in this assessment is aimed to position COES at the forefront of innovation in control center and operational capability. It is an ambitious plan that aims to ground the development of operational technology and the control center in the context of rapidly increasing generation, demand, and network growth in the coming decade. The road map is structured in five key areas: architecture, data, control center tools, human factors, and buildings and hardware, with eleven key pillars of innovation within each area. Part of the framework included developing a potential pathway to 2030 and beyond, while recognizing the uncertainty in projected growth forecasts. The roadmap is not intended to be an implementation plan or course of action for COES to follow necessarily, but rather is an indicative and visionary way of considering the best approaches for achieving their operational goals.
