Iceni is the world\u2019s first utility-scale battery directly integrated into offshore transmission infrastructure. Rather than securing a standalone grid connection, the project will share transmission assets and an onshore grid connection with Hornsea 3 and is scheduled to become operational in Q1 2027.<\/p>\n
As one of the UK\u2019s first large-scale \u2018pathfinder\u2019 co-location projects under the Offshore Transmission Network Review (OTNR), Iceni is designed to improve coordination between generation and storage assets and maximise the efficient use of existing grid infrastructure.<\/p>\n
Under the agreement, Arenko will deploy its full Nimbus platform to manage trading, optimisation and Asset Management of the battery asset.<\/p>\n
Iceni is widely regarded as one of the most technically and commercially advanced battery developments in Europe, combining utility-scale storage with the operational complexity of a major offshore wind asset, sharing a single grid connection.<\/p>\n
\u201cIceni is a highly sophisticated project, coupling a grid scale battery with one of the UK\u2019s biggest offshore wind farms\u201d said Rupert Newland, CEO, Arenko. \u201cThis creates significant opportunities, but also operational and trading challenges, from forecasting and deciding how and when to allocate capacity in real time, to the technical, data and controls integrations between the two assets. We\u2019ve worked closely with \u00d8rsted over time as their thinking around flexibility has evolved, and with projects like Iceni they are taking a pioneering role in bringing truly significant generation capacity and utility-scale storage together. Nimbus is built for that kind of environment, providing the automation and optimisation capabilities needed to manage increasingly large and complex assets, across multiple markets.\u201d<\/p>\n
Arenko was selected for its deep expertise in battery optimisation, short-term power markets and flexible asset management.<\/p>\n
Iceni has been described by \u00d8rsted and the market as a \u2018blueprint for the future\u2019 of co-located energy infrastructure. As a Path Finder project it is demonstrating how shared grid connections between offshore wind and battery storage can increase output, improve system efficiency and reduce the need for additional network build-out.<\/p>\n
\u201cWhat makes Iceni interesting for us isn\u2019t just the scale of the battery, but how it works alongside Hornsea 3\u201d added Katinka Hussman Palbo, Vice President, Global Trading & Revenue, \u00d8rsted. \u201cWe are aiming to optimise two very different assets, wind and storage, through a shared connection point, while ensuring that both deliver significant value to the grid.\u201d<\/p>\n
Arenko\u2019s Nimbus platform is increasingly being adopted to manage and monetise complex co-located projects, having been deployed across 14 large-scale co-location projects to date. Data from existing Nimbus-enabled assets shows that automated trading strategies can enable co-located systems to match – and exceed – the revenue performance of standalone battery projects, with several of these assets performing in the upper percentiles for annualised revenue performance.<\/p>\n
Originally developed in the UK BESS market, Nimbus is now deployed across more than 1.2 GW of utility-scale battery, hybrid and renewable generation assets across the UK, Europe and the US.<\/p>\n
