COMPANY PREPARATION GUIDEPreparing for a job at ESB
Preparing for a role at ESB means understanding how electricity generation, networks and customer supply fit together while developing the judgement to make dependable decisions about essential infrastructure.
What ESB is known for
ESB is Ireland's largest electricity company and owns and operates the country's distribution network.
Its activities span generation from gas, wind and hydro, electricity supply through Electric Ireland, and transmission networks in Northern Ireland.
Beyond Ireland, ESB invests in wind energy and provides engineering consultancy.
What tends to matter at ESB
The capabilities that shape most roles here, and how to get ready for each.
Whole-system thinking
A decision about generation, networks or supply can affect other parts of ESB's electricity business.
How to prepare: Map how power reaches customers and identify where your target role contributes to reliability, cost or service.
Network reliability
Maintaining a distribution network calls for careful technical decisions and coordinated responses when conditions change.
How to prepare: Bring an example of diagnosing a fault, prioritising work or communicating a service issue without losing sight of safety.
Generation trade-offs
ESB's mix of gas, wind and hydro makes technical and operational trade-offs relevant across its generation work.
How to prepare: Review how each source differs in availability and operation, then practise explaining a practical choice between them.
Customer perspective
Electric Ireland connects ESB's wider electricity activities with the people and organisations buying power.
How to prepare: Consider how you would explain a technical constraint or service change clearly to a customer-facing colleague.
The MinTraq readiness lens for ESB
MinTraq measures readiness in four areas. Here is how each one applies at ESB.
Match your core expertise to the part of ESB you want to join: network engineering, generation and electricity supply call for different working knowledge. Learn the handoffs between your area and the others.
Prepare to weigh reliability, safety and customer impact when a straightforward solution is not available. Use examples that show how you set priorities and communicate decisions.
For leadership roles, show how you coordinate specialists across work with shared consequences, such as network maintenance or generation planning. Explain how you keep decisions clear when priorities compete.
AI readiness is relevant where data may help monitor equipment, forecast demand or improve customer support. Be ready to distinguish a useful insight from a decision that still needs human checking.
Same company, different preparation
Preparing for ESB is not one thing. What you need to show depends on the role you want.
