*It behaves as a ''system'' - as a set of interdependent parts. It should not be compared with car manufacturers competing for market share but with a single car, the parts of which are mutually dependent. | *It behaves as a ''system'' - as a set of interdependent parts.

*Very effective computational models are available for predicting the behaviour of an electricity system. This modelling is used to ensure that that the system will meet standards for reliability and resilience with respect to: security of generation supply, system inertia, network fault recovery, synchronous generation, reactive power, black start recovery, etc.(more). | *Very effective computational models are available for predicting the behaviour of an electricity system. This modelling is used to ensure that that the system will meet standards for reliability and resilience with respect to: security of generation supply, system inertia, network fault recovery, synchronous generation, reactive power, black start recovery, etc.(more). The models are key tools that underpin a system design and investment planning process. | ||

Despite opposition from members of parliament who believed that competition was essential, the 1926 Electricity Act enabled 'Electricity Commissioners' to use system planning to create the National Grid, that greatly improved reliability and, between 1926 and 1960, significantly reduced the price of electricity in real terms - see [https://engineers.scot/office/resources/publications/engforenergy.pdf Engineeering for Energy], page 9. | Despite opposition from members of parliament who believed that competition was essential, the 1926 Electricity Act enabled 'Electricity Commissioners' to use system planning to create the National Grid, that greatly improved reliability and, between 1926 and 1960, significantly reduced the price of electricity in real terms - see [https://engineers.scot/office/resources/publications/engforenergy.pdf Engineeering for Energy], page 9. | ||
Pre-1990 the UK Electricity Boards (CEGB, SSEB and NSHEB) provided a reliable supply and worked successfully to keep costs down. They did forward planning that identified the optimum location and type of generation plant in relation to a range of issues such as system cost, fuel source proximity, operational flexibility, fuel supply security etc. | Pre-1990 the UK Electricity Boards (CEGB, SSEB and NSHEB) provided a reliable supply and worked successfully to keep costs down.
