Barry Dell Plumbing operates around the clock and provides emergency callout services, but the power unexpectedly went off on Thursday morning.
Co-owner Liz Carmichael said she missed the email notice on May 4, but she expected a more robust notification process from her provider, Meridian Energy.
After her inquiries, it offered her $50 towards a generator hire for her Dunedin business, which employs 25 staff.
The heating, lights, various machinery and the company’s computer network, including the phones, went down shortly after staff arrived on Thursday at premises in the South Rd.
Meridian head of customer care and delivery Rachel Herangi said the company received between 800 and 1000 notifications from network companies each week, and it relied on its processes "to do the best by our customers".
"We do rely on customers reviewing the planned network outage information that is sent to them, which always clearly states in the subject line, ‘planned outage’," she said.
An Aurora spokeswoman said in some instances the company made an additional courtesy call to large customers who were heavily reliant on electricity.
"For example, medical facilities, food production, etcetera," she said.
The company’s website said scheduled pole replacements left about 95 Mornington customers without power from about 8.30am to 5pm on Thursday.
