ESB Networks — status

ESB Networks is the vital, ring-fenced subsidiary of the Electricity Supply Board (ESB) Group, functioning as the licensed operator for the electricity distribution system across the Republic of Ireland. ESB itself is majority-owned by the Irish Government (approximately 97%), making ESB Networks a key state-owned utility responsible for the nation’s electrical infrastructure. Its core mandate is to finance, build, maintain, and safely operate the vast national electricity network, which includes over 155,000 km of overhead lines and 23,500 km of underground cables, connecting more than 2.3 million customers in homes, farms, and businesses. ESB Networks holds the licenses for the Distribution System Operator (DSO), the Distribution Asset Owner (DAO), and the onshore Transmission Asset Owner (TAO), meaning it manages all the infrastructure from bulk supply points right to the customer’s meter. The entire operation is subject to strict regulatory oversight by the Commission for Regulation of Utilities (CRU), which sets price controls and determines the allowable revenue collected through 'Use Of System Charges' billed to customers by electricity suppliers. The company's strategic direction is fundamentally driven by its "Networks for Net Zero" strategy, committing it to enabling Ireland's clean electric future and supporting the government's target of decarbonization by 2040. This involves radical transformation of the network from a passive system to a smart, flexible grid that can handle high volumes of intermittent renewable energy, such as wind and solar, as well as enabling the widespread electrification of heat and transport. Key targets for the network development by 2030 include connecting up to 22 GW of renewable generation, enabling one million electric vehicles (EVs), and connecting 680,000 heat pumps to the distribution system. This infrastructure upgrade is crucial to ensuring a reliable and resilient supply amidst these massive changes in energy generation and demand. A flagship project underpinning this transformation is the national Smart Meter Programme, an essential upgrade replacing traditional meters with digital smart meters. Over two million smart meters have now been installed, providing significant benefits like automated, accurate meter readings, which greatly reduces the need for estimated bills. Crucially, these meters record detailed time-of-use consumption data, enabling electricity suppliers to offer smart tariffs that incentivise customers to shift usage away from peak times (typically 5 pm to 7 pm), thus managing peak demand on the network. They also empower customers with access to their energy usage insights via the ESB Networks Online Account and facilitate microgeneration export payments for those who generate their own electricity, such as with solar panels. Services offered by ESB Networks include connecting new customers, modifying existing lines, managing power outages, and maintaining the system's overall safety and integrity. The company is actively focusing on resilient infrastructure and empowered customers as its core pillars to ensure a safe, sustainable, and flexible low-carbon energy system for all of Ireland.
