Energy bills are set to rise - but not just due to the Iran war.
Network upgrade costs, not just global events, are a major driver of rising UK energy bills.
KEY POINTS
- Britain's grid overhaul is expected to cost £70bn over the next five years.
- Network costs alone could add £135 to annual household bills by 2030, according to analysts.
- A 2009 Ofgem decision allowed wind farms to connect before grid expansion, contributing to underinvestment.
- Many network upgrade costs are already unavoidable due to a backlog of wind farms awaiting connection.
