School Comparison Tool

This tool allows you to compare the energy performance of a number of schools within a Local Authority group or across the whole of Energy Sparks. The aim is to allow you to identify the best and worst performing schools to provide examples of best practice and to identify the schools needing the most support to improve their energy management.

Benefit of moving to or away from a differential tariff

This is HTML content

Electricity is generally charged at a flat rate, for example 12p/kWh whatever the time of day. Your energy company's costs however vary significantly depending on supply and demand at different times of day, from perhaps 4p/kWh overnight to 25p/kWh at peak times. Electricity companies generally offer differential tariff's (economy 7) which have lower overnight costs (typically 8p/kWh) and slightly higher daytime costs (13p/kWh) to users who have high overnight consumption to share the benefit of cheaper overnight wholesale costs.

Typically, this should benefit schools with storage heaters, however many schools with storage heaters are on a single flat tariff and fail to gain from lower overnight prices.

The chart and table below estimate the potential benefit of switching to or from a differential tariff.
