Who Benefits from Rational Electricity Time-of-Use?

If "we" stand to gain £56 billion from 7GW less of nuclear capacity by rational electricity time-of-use, who benefits? Who are "we"?
In the end, we all gain, either as bill-payers or as taxpayers, or as members of their households.
The suppliers will benefit in the short term by paying lower half-hourly wholesale prices at peak times.
