What causes changes in electricity prices?

Electricity prices have risen significantly over the past decade largely due to increases in network costs. The 'network' is the transmission and distribution system of poles and wires that carries electricity to your home.

The repair and replacement of ageing poles and wires, increased peak demand (periods placing the highest demand on the energy network—such as hot summer days), population growth, and rising standards for power reliability have all contributed to network cost increases.
