1 Gas Interruptions customer guide

2 December 2006 Dear Customer Gas Interruptions Customer Guide We have produced this guide for customers who take interruptible gas supplies from us. The new gas year commences on 1st October 2006 and this version replaces previous guides. Interruptions are not optional and penalties for failure to interrupt when directed can be severe. Therefore it is important that we work together to ensure that the necessary processes are in place for interruption notices to be served effectively and acted upon appropriately. This guide will help you understand the actions you must take and the documentation used in the process. New gas distributors join the market There are now a number of gas transporters responsible for calling gas interruptions on their respective networks. In June 2005, *Transco sold four of their distribution networks to new owners (known as DNOs) although they retained ownership and control of the National Transmission Service (NTS) network and the remaining four distribution networks. However procedures for notifying you of an interruption and the actions you must take have not changed. The Health and Safety Executive has an interest in the ability of gas customers to shut down during system emergencies. * On the 10th October 2005 the trading name of Transco Plc was rebranded as National Grid Gas Plc Npower Commercial Gas Ltd or Npower Direct Ltd is the supplier and shipper of gas under your contract. Out of normal working hours (7pm 8am) when most interruptions take place, the Gas Operations team of our affiliate company RWE Trading based at Swindon act on our behalf to support the interruption notification process. They should be your first point of contact for any query about a gas interruption, and can be reached on Keeping information up to date We will be working with you to update the Authorised Customer Contact details during the year. Remember, you MUST advise us immediately of any changes - you can contact us by: Phone: / 2684 Fax: Gas.Demand.Forecasting@npower.com Please julie.bond@npower.com to confirm you have received this booklet. Yours sincerely Julie Bond Gas Customer Relationship Management Npower Commercial Gas Ltd/Npower Direct Ltd 2

Overview of interruptible status Interruption safeguards the ability to supply gas on the transportation network particularly to domestic customers.

System safety is paramount at all times and some sites are on critical parts of the gas network.

4 Overview of interruptible status Interruption safeguards the ability to supply gas on the transportation network particularly to domestic customers. National Grid Gas/DNOs will only interrupt sites after they have assessed all other options available to them and aim to do so equitably across all sites on their network. System safety is paramount at all times and some sites are on critical parts of the gas network. National Grid Gas/DNOs may decide it is necessary to deem their status as network sensitive and may therefore need to interrupt these sites more often. If your consumption is over 5,860,000 kwh (200,000 Therms) per annum, you can choose to be supplied as an interruptible customer. You benefit from a lower transportation charge (by not paying exit capacity charges) in return for agreeing to have your gas supplies interrupted up to a maximum number of days as specified by the gas transporter. This excludes emergency situations. National Grid Gas/DNOs can call interruptions up to this specified maximum number of days in order to overcome transportation constraints on their network and, to a limited extent, for test purposes. Customers and their suppliers can also agree additional interruption days (see Commercial Interruptions). If your consumption falls below 5,860,000 kwh, and you remain with the same supplier, it is likely that you will be able to keep your status as interruptible. Should you change supplier at any time, the new supplier would be obliged to register you as a Firm customer. You can of course apply via your supplier to become Firm at any time, however this is not guaranteed and National Grid Gas/DNOs will advise if this is possible. The cost of supplying your site(s) would increase to reflect the higher transportation charges resulting from firm sites being required to pay exit capacity charges. You may need a secondary fuel supply to maintain essential services on site in the event of the gas supply being interrupted. It is recommended that each site ensures that secondary fuel supplies are always available and maintained regularly. The following page contains an example of the contract documentation completed by you at the start of the supply contract with npower. 4

Other interruption services available Over the years additional products have been introduced to provide some degree of flexibility for Interruptible gas customers.

Due to its nature, when a gas interruption is called, Interruptible customers are obliged to turn all gas supplies off and where possible switch to an alternative fuel.

13 Other interruption services available Over the years additional products have been introduced to provide some degree of flexibility for Interruptible gas customers. When demands on gas transportation networks exceed capacity, the relevant gas transporter must reduce demand to overcome the shortfall, thus maintaining safe and secure supplies to Firm users. Due to its nature, when a gas interruption is called, Interruptible customers are obliged to turn all gas supplies off and where possible switch to an alternative fuel. Whilst this gives them the benefit of lower transportation costs, the practicalities of turning everything off can be difficult to manage, especially when some essential services are driven by gas. npower is a leading supplier of gas and electricity to businesses in the UK and can offer our gas customers protection against full Interruption. IFA The Interruptible Firm Allowance (IFA) was developed to help you keep essential site services running and hence avoid punitive charges that could arise if you failed to interrupt all supply of gas to the site. The available capacity of an IFA is always limited by the relevant transporter due to local network constraints at the time and cannot be exceeded, otherwise this would in itself be deemed as a failure to interrupt. npower can offer you some protection against full interruptions through an IFA agreement. There is a one-off charge and an IFA contract runs for 12 months from 1st October (the gas year). They are transferable between suppliers. Partial Interruption Partial Interruption allows customers to potentially turn down their supply in various agreed tranches from full load to zero. You may therefore be able to run some services but could still be asked to turn off completely. Swap Option This allows equivalent supply points, one Firm and one Interruptible, to swap their supply status on a permanent basis. Buddying Option This allows the temporary reallocation of Firm capacity to an Interruptible supply point where system constraints permit. Likelihood of Interruption This service gives the risk of an interruption being called and is available daily on the National Grid website More details on these services For further information please contact your Account Manager or call our Gas Operations Team on * Visit our website at: Alternatively us at i&ccustomercontact@npower.com 13

Commercial interruptions This would involve a similar interruptions process, but with npower determining the requirement for interruption and not National Grid Gas/DNOs.

In the event of an actual interruption called by National Grid Gas/DNOs during a Commercial Interruption called by npower, National Grid Gas/DNOs interruption would take

14 Commercial interruptions This would involve a similar interruptions process, but with npower determining the requirement for interruption and not National Grid Gas/DNOs. This would be in addition to the 45 days required by National Grid Gas/DNOs. In the event of an actual interruption called by National Grid Gas/DNOs during a Commercial Interruption called by npower, National Grid Gas/DNOs interruption would take precedence. Please contact your account manager if you would like further details regarding this. * Calls made from a BT landlines will be charged at national rates. Calls charges from non-bt landlines may vary, callers should check with their provider before calling. 14

On subsequent days, the charge is calculated using actual off-take multiplied by twice the difference between gas and gas oil prices as published by the Department of Trade and Industry.

15 Failure to interrupt Failure to interrupt carries with it severe financial consequences. With a first failure, the charge levied by National Grid Gas/DNOs is twice the annual NTS/LDZ capacity charge regardless of the excess gas offtaken. On subsequent days, the charge is calculated using actual off-take multiplied by twice the difference between gas and gas oil prices as published by the Department of Trade and Industry. If you do not turn your gas off, National Grid Gas/DNO engineers have the right to enter your site and isolate the supplies accordingly. Customers who have failed to interrupt have seen bills for many tens of thousands of pounds for an individual failure, and your site could be re-designated as Firm for charging purposes for a period of 2 years and still be asked to interrupt. Multiple failures could involve liabilities of significant sums of money. Disconnection could follow, along with a safety warning. 15
