They might lose 5pc of customers but.....
"Contact would still sell all the electricity it generated, about 28 per cent of national output, and the loss of some of its retail base would be taken up by commercial or wholesale clients"
...and wouldn't commercial/wholesale be 'cheaper' customers to have?....would it mean they wouldn't have to buy as much on the spot market? Maybe a reduction in customer base is a good thing for profitability? ....well in the short term until further generation assets are built to service a larger client base.
