Utilities are increasingly seeking to impose additional integration charges on wind and solar generators to compensate for variability and uncertainty. Renewable Reserve Sharing Groups may provide a way to help reduce or eliminate those charges. There are two distinct ways that wind and solar generation can impact utility balancing requirements: Minute-to-minute variability of wind and…

Introduction As the growth of inverter-based resources (IBRs), such as photovoltaic, wind energy, and batteries, increases in order to decrease the carbon footprint of energy sources, utility protection engineers increasingly ask the question: “Are the protection systems installed at present capable of protecting power systems with a high penetration of IBRs?” Before we can answer…

Australia’s energy system is transforming at a pace and magnitude not previously seen or imagined. The disruption facing power systems across the globe is accelerated in Australia, as an electrically islanded nation. Indeed, by many metrics, change is happening faster in Australia than in almost all other developed economies, and it’s occurring in a physical…

This is part 2 of a two-part blog articulating the view of Jonathan O’Sullivan of the Eirgrid Group, which has TSO responsibilities for the systems of Ireland and Northern Ireland.  The view encompasses how the industry evolved to its current state, and where it needs to go from here to satisfy the goals and needs…

“Storing Energy at Sea (StEnSea)” is a novel pumped storage concept for storing large amounts of electrical energy offshore. In contrast to well-known conventional pumped-hydro power plants, this concept greatly expands the siting possibilities, and allows for modular construction and ease of assembly.  Instead of two separated water reservoirs of different heights, the StEnSea concept…
