The MP for the Hexham constituency has also said that residents came forward with recommendations that will help improve community resilience ahead of future storm events.
The meetings were held at Darras Hall Primary School in Ponteland last Thursday and Bellingham Town Hall last Friday.
They were an opportunity for the views of Mr Opperman’s constituents to be heard by representatives of the various stakeholders that were involved in responding to the devastating consequences of the late November storm.
Evidence from the meetings will form a report, which will be sent to Ofgem to be considered as part of its review.
Mr Opperman said: “I am grateful for the excellent contributions from the attendees at the meetings in Ponteland and Bellingham.
“Both meetings proved to be successful events and I look forward to using evidence from the meetings in a report, which I will be sending to Ofgem to be considered for their review.
“I also want to thank Northern Powergrid, Northumberland County Council, Northumbrian Water and other organisations for attending these events, and for addressing the concerns of my constituents.”
