30-minute usage data is the information regarding your energy consumption in every half hour period. Your 30-minute usage information will be logged remotely by your smart meter if you’ve opted for Interval (30 minute) Smart Services. ESB Networks will connect with your meter throughout the day to receive your 30-minute usage information, which will be sent to SSE Airtricity the following day. You will be able to access this 30-minute usage data at your Business Online account. Your account will be updated daily.
