ENERGY PRICES TO FALL

Scottish & Southern Energy PLC 28 February 2007 ENERGY PRICES TO FALL STARTING FROM 1 MARCH 2007 Scottish and Southern Energy plc ('SSE'), currently the UK's cheapest supplier of energy*, has decided to implement cuts in prices for domestic customers, starting from tomorrow (1 March)**. It will: •cut the average annual gas bill* by £72, to £534, a decrease of 12%, starting from 1 March; •cut the average annual electricity bill* by £18, to £355, a decrease of 5%, starting from 1 April; and •cut the average annual dual fuel* bill* by £89, to £873, a decrease of 9%. Average annual dual fuel bill following all forthcoming price changes* Energy Supplier £ per annum inc VAT % Difference Scottish and Southern 873 - Npower 909 +4.1% EON UK (Powergen) 913 +4.6% British Gas 953 +9.1% EDF Energy 971 +11.2% Scottish Power 990 +13.4% This means SSE will continue to be the UK's cheapest supplier of energy, even after all the recently-announced price cuts take effect.* SSE will waive any termination fees which may apply to any of its customers who are on its fixed price tariffs to enable them to take advantage of its new, lower prices without any penalty, if they wish. SSE supplies energy as Southern Electric, SWALEC, Scottish Hydro Electric and Atlantic and is the UK's third largest supplier of energy, with over 7.5 million customers. During periods of rising wholesale energy prices, SSE passed on to its customers much less than the full extent of the increases and it delayed any price rises for as long as possible. As a result, its customers have now paid an average of £340* less for their gas and electricity in the last three years than have customers of British Gas. SSE announced on 31 January that it had written to its customers to confirm that it would cut gas and electricity prices within the next few months. Alistair Phillips-Davies, Energy Supply Director of SSE, said: 'While wholesale energy prices were rising in recent years, we protected our customers from the worst impacts of the increases, with the result that we have been the UK's cheapest supplier of energy for most of that period. 'Since last September, we have made clear our intention to cut gas and electricity prices if there was a sustained fall in wholesale prices which would allow us to do so, and so I am very pleased that we have now been able to make this announcement. It means we are able to start cutting prices immediately. 'Energy prices are driven by a number of factors and future trends in wholesale gas and electricity prices are always difficult to predict. Nevertheless, I hope that today's announcement marks the start of a sustained downward trend in the prices paid by customers.' *Based on the average standard quarterly payment across Great Britain and on annual consumption of 20,500kWh of gas and 3,300kWh of electricity. Prices include VAT but exclude Early Payment Discount of 4.3% which SSE offers to customers who pay their bills quarterly. SSE is one of just two energy suppliers to offer such a discount. **The lower prices will be applied to gas usage on billing periods that commence on or after tomorrow (1 March). For electricity, the lower prices will be applied to usage on billing periods that start on or after 1 April.
