Select Committee on Trade and Industry Written Evidence


APPENDIX 10

Memorandum by Ofgem

SUMMARY

    —  Ofgem welcomes the Trade and Industry Committee's inquiry into issues arising from the storms in October 2002, which left nearly two million customers without power, some for as long as nine days.

    —  Ofgem has dealt with well over 3,000 requests for determinations over disputed claims for compensation. Over 2,700 of these customers will be receiving compensation.

    —  Around 18,000 customers who did not request determinations will also receive compensation.

    —  The problems were not caused by the overall level of investment in the networks—an independent report has found that "there appears to be no fundamental reason why . . . companies that performed less well . . . should not meet the standards set by the best".

    —  Ofgem is working with industry to improve the ability of network companies to deal with any future incidents and, in particular, to improve the mechanism for payment of compensation to customers.

A.  INTRODUCTION

  1.  Ofgem welcomes the Trade and Industry Committee's decision to conduct an inquiry into the issues arising from the October storms including electricity distribution companies' progress in addressing the issues highlighted in the BPI report, the arrangements for payment of compensation to customers affected by power failures and the determination of disputes by Ofgem over claims for compensation that were turned down by these companies.

  2.  This submission sets out some background information to set the storms in context, outlines the relevant features of the regulatory framework, explains the process Ofgem has taken in determining compensation claims and outlines the approach Ofgem is taking to improve the regulatory arrangements in this area.

B.  BACKGROUND

  3.  The storms of 27 October 2002 affected much of Southern England, the Midlands and Wales. The storms caused extensive damage to the electricity distribution networks in these areas[10] with almost two million customers without electricity for varying lengths of time. Most customers were reconnected within the first 18 hours by their electricity distribution companies, although a substantial number were without power for much longer periods. The worst served customers were without power for up to nine days.

  4.  The aftermath of the storms brought by far the largest number of determination requests that Ofgem has ever faced and has demonstrated practical difficulties with the existing regulatory framework.

  5.  The performance of some of the affected distribution companies in the October 2002 storm fell short of the standards that should be expected. However, some of the worst affected companies performed substantially better in reconnecting customers and had either no or very few claims for compensation passed to Ofgem for determination.

  6.  We note the conclusion of the BPI report that said "there appears to be no fundamental reason why those companies that performed less well on this occasion should not meet the standards set by the best in how the event was anticipated and managed. Even among the best performing companies there is no room for complacency." The BPI report also notes that "there are a number of areas that have differentiated companies on this occasion, in which all companies should be able to match the performance of best performing companies with minimum cost and minimum time delay".

  7.  Many of the distribution companies have made substantial improvements in quality of supply performance since the early 1990s, with the average number of power cuts per customer having fallen by 11% and the average duration having fallen by at least 30%. These figures understate the true extent of improvements because numbers of customers interrupted and duration were historically under-recorded. [11]

  8.  Current average levels of performance are better than those in most other European countries. [12]

  9.  Studies of resilience[13] and asset risk management[14] practices conducted prior to the October 2002 storms generally did not demonstrate major cause for concern. However, there is not a strong correspondence between the findings of these studies in respect of individual companies and their actual performance in response to the storms. This demonstrates that while these studies provide useful background information it is important that the regulatory regime continues to focus on outputs. For example, focussing on targets in relation to the number and length of power cuts rather than the detailed monitoring of investment plans which were not the main contributory factor to poor performance.

C.  REGULATORY FRAMEWORK

Overview

  10.  Ofgem's principal objective, as inserted into the Gas and Electricity Acts by the Utilities Act 2000, is to protect the interests of present and future consumers of electricity and gas, wherever appropriate by promoting effective competition. Ofgem has other important duties, including in relation to security of supply, the environment and ensuring that companies can finance their activities to meet their obligations.

  11.  In the case of the electricity distribution companies, Ofgem protects consumers through a combination of regulatory instruments, including financial incentives provided primarily through price controls, licence obligations setting out requirements to (or not to) act in particular ways and other secondary legislation such as statutory instruments and determinations.

  12.  One of the main benefits of incentive regulation is that it leaves detailed operational decisions where they are usually best taken, with company management, but rewards or penalises the company for the outcome of those decisions. This is generally much more effective in protecting customers' interests than for an economic regulator or Government to tell companies how to go about their business. In Ofgem's experience (see for example, paragraph 9 above), it is not practicable for the regulator or its consultants to predict or judge in advance which management policies will work best and it may be counter-productive to try to make such judgements.

  13.  Inevitably, any form of incentive regulation will reward only those aspects of desirable behaviour which can be measured, monitored and to which a value can be attributed. It is therefore necessary also to rely on broader obligations, and these are an essential part of the regulatory regime. For example, distribution companies have a statutory duty to develop and maintain an efficient, co-ordinated and economical system of electricity distribution.

Key aspects of current regulatory arrangements

  14.  The price controls on network monopolies are typically reviewed every five years. The last price control review of the distribution companies was concluded in December 1999 (DPCR3). [15]The next review (DPCR4) is now underway[16] and is expected to conclude in late 2004.

  15.  As part of each price review, Ofgem considers the overall level of capital expenditure which should be assumed in setting price limits, based on evidence from the companies and analysis of their requirements. It is important to allow companies to recover and earn a reasonable return on their investments in order to ensure they are willing to invest and to give them incentives to invest efficiently and effectively, in order to protect the interests of consumers. However, the capital expenditure assumption does not determine investment levels nor authorise specific investment projects—the key drivers of actual capital expenditure are the obligations and incentives that companies face. If improvements in a particular output are required, it is therefore appropriate to focus on incentives to achieve that objective rather than to prescribe an amount of money to be allowed in the price control. The level of the incentive would ideally be based on the willingness of customers to pay for the improved output.

  16.  During the course of DPCR3, Ofgem recognised that the regulation of quality of service that distribution companies deliver was in need of improvement. Over the following years, Ofgem undertook a major review (the Information and Incentives Project or IIP), to establish more accurate and comparable information on the quality of service delivered by the distribution companies and then to implement an incentive regime. [17]

  17.  The framework of output measures and output-based incentives in place on the distribution companies currently has four main elements:

    —  output measures that are subject to direct financial incentives under the price control—the number and duration of interruptions to customers' supply, the quality of telephone response and the quantity of electrical losses (see paragraphs 18 and 19 below);

    —  output measures to monitor performance between reviews, including more detailed information on interruptions and information on the speed of telephone response and a range of Overall Standards of Performance relating to areas such as making and keeping appointments and replying to correspondence;

    —  Guaranteed Standards of Performance whereby individual customers may be due compensation if the distribution company fails to meet a specified standard of performance (see paragraph 22 to 25 below); and

    —  a survey of asset risk management policies and procedures (see paragraph 26 below).

  18.  Following any incident on their network, distribution companies may face financial implications from the overall incentive on the aggregate annual number and duration of interruptions and/or from Guaranteed Standards in respect of individual customers.

  19.  Under the general quality of supply incentives, each distribution company has a target[18] level of performance for the number of customers interrupted and the total duration customers are off supply (termed "customer minutes lost"). If annual performance is worse than the target, companies face a penalty of up to 1.75% of price controlled revenue (capped at 0.875% in 2002-03 as this was the first year in which the penalty applied). Companies that have improved performance and beaten their targets may also be eligible for rewards in 2004-05.

  20.  Distribution companies also face rewards or penalties of up to 0.125% of their revenue, on an annual basis, depending on their relative quality of telephone response. This is assessed through a monthly consumer survey.

  21.  Distribution companies may claim an adjustment for events which they believe were exceptional and had a significant impact on their performance. Ofgem has developed tests to judge whether the event is sufficiently exceptional and the impact material. In deciding the extent of any adjustment Ofgem will take into account whether the distribution company has taken all reasonable steps to restore customers in an efficient and effective manner.

  22.  Under the Guaranteed Standard on Supply Restoration[19] domestic customers are entitled to £50 compensation (business customers £100) if their electricity supply is not restored within 18 hours. [20]Customers are entitled to an additional payment of £25 for each subsequent period of 12 hours that supply is not restored. In order to trigger a payment under this Standard, the electricity distribution company must receive a claim for compensation from the customer within one month of their supply being restored.

  23.  However, distribution companies are legally entitled to claim an exemption from making such payments under this Standard if exceptional circumstances prevented them from restoring supplies in the relevant timescales, provided that they took reasonable steps both to design and maintain their network and to reconnect customers. Examples of exceptional circumstances under this Standard include severe weather or inability to access premises to restore electricity supplies. [21]

  24.  The exemptions were introduced as part of the standards of performance arrangements in 1991 in recognition of the fact that there may be circumstances outside the control of companies which prevent them from restoring customers' supplies within the relevant timescales. Requiring companies to pay out compensation is such cases would expose them to higher levels of risk.

  25.  Customers are entitled to dispute a company's exemption claim, initially with energywatch, and then to seek a determination from Ofgem. In such cases it is Ofgem's job to decide whether the company was acting within its legal obligations in applying the exemption and therefore whether the customer should be paid compensation.

  26.  The current incentive arrangements all focus on current network performance. Ideally, regulatory arrangements would also take account of the impact of decisions made by companies today on their future performance. However, future performance is, by its nature, impossible to measure today. Ofgem considers that there are two main ways in which future performance can be addressed through the regulatory framework:

    —  by reviewing the decision-making processes and procedures that companies have in place, which has been done through the Asset Risk Management Survey. This is intended to promote good practice and to provide Ofgem with an early warning of potential problems, but cannot be a perfect indication; and

    —  by creating an expectation that there will be adverse consequences from poor performance in future. The development and evolution of the existing regulatory framework is in part intended to make this clear to companies.

  27.  In a paper published in February 2003, [22]Ofgem set out the approach it proposed to take to develop the regulatory framework and has been working on this review in parallel with determining the compensation claims (see section E below).

D.  STANDARDS OF PERFORMANCE CLAIMS FOLLOWING THE OCTOBER STORMS

Background

  28.  Over 3,250 customers that were off supply for longer than 18 hours following the October 2002 storms have asked Ofgem to determine disputes relating to the application of exemptions discussed in paragraphs 22 to 24 above. This is the largest number of disputes that Ofgem or its predecessor OFFER has had to deal with. [23]The large majority of determination referrals came to Ofgem via energywatch although a small number of customers contacted Ofgem directly. Ofgem began receiving determination requests from energywatch in January 2003 with the majority received and logged on our database by the end of March. However, Ofgem has continued to receive a modest number of determination requests since this date and energywatch are still processing requests.

  29.  The work on determining the disputes has now been completed and Ofgem will be issuing its decisions in the week commencing 1 September 2003. The approach to determining the disputes is set out below.

General approach adopted to determine the October storms disputes

  30.  For an event of the scale of the October storms the companies' approach to maintenance and emergency planning will have a significant effect on their overall performance in restoring customers. The speed with which each customer can be reconnected will also be closely inter-related. Even the most efficiently managed company will only have finite resources to deploy in restoring supplies. This means that the resources used to reconnect one group of customers will not be available to reconnect others. Given these circumstances it was not practicable to settle customers' determinations on an individual basis.

  31.  It was necessary to use an approach which assessed both the effectiveness with which companies restored supplies generally and their success in prioritising restoration across customers. Ofgem has therefore adopted a method which involves grouping customers and assessing companies' effectiveness in restoring individual customers in each group relative to companies that performed well during the same event.

  32.  This approach is consistent with the conclusions of the DTI storms report that said "there appears to be no fundamental reason why those companies that performed less well on this occasion should not meet the standards set by the best in how the event was anticipated and managed. Even among the best performing companies there is no room for complacency".














Grouping of customers

  33.  Customers have been grouped according to the complexity of faults that their distribution company had to deal with in order to restore their supplies. This has been based on the number and voltage of faults affecting each customer. Where customers' supplies have been affected by a larger number of faults it will typically take longer to restore their supplies. It is also generally accepted that efficient prioritisation of supplies means the repair of those faults that will restore supplies to the greatest number of customers. This will tend to mean that higher voltage faults are restored first. The next priority would normally be given to low voltage faults, followed by circuits that connect individual customers.

  34.  Customers have therefore been divided into four groups whose membership is mutually exclusive. Group 1 contains the customers whose supply was interrupted by one or more High Voltage ("HV") faults. Group 2 contains customers whose supply was interrupted by one or more Low Voltage ("LV") faults, possibly in combination with HV faults. Group 3 contains customers whose supply was interrupted by a single LV Service fault. Group 4 contains customers whose supply was interrupted by other combinations of faults including at least one LV Service fault.

Benchmarking performance

  35.  The two companies that have been used to benchmark restoration performance are Western Power Distribution (WPD) South-West and South-Wales. They were chosen as the benchmark companies for several reasons:

    —  the storms had at least as severe an impact in their areas as for other companies;

    —  they had similar levels of tree coverage as other companies;

    —  their performance in restoring customers was good; and

    —  they had no outstanding determination cases.

  36.  For each group of customers, Ofgem analysed a large sample of WPD data and any key differences in circumstances between companies to establish benchmark restoration times. In Ofgem's judgement these are the times at which a company that had taken all reasonable steps could have been expected to have restored electricity supplies to all customers in the group and at which the exemptions should therefore cease to operate. Customers are then entitled to £25 compensation at the next standards of performance contravention time[24] and for each additional 12 hours period thereafter.

  37.  The benchmark times are set out in Table 1 below:

  39.  Some customers experienced more than one power cut lasting more than 18 hours as result of the October storms. Such customers will receive full payment under the Standards of Performance for any further power cuts lasting longer than 18 hours in addition to any payments they are due for under Table 1 above.

  40.  If customers have already received ex-gratia payments from their distribution company these will be deducted in calculating the final payment to be made to the customer.

Payments to other customers

  41.  In addition to the determinations the electricity distribution companies have also agreed to make payments on the same basis to other customers whose claims were received within one month of their supply being restored. These customers have a right to request a determination from Ofgem but have not done so. The companies will be making payments to around 18,000 additional customers. These payments are estimated to exceed £1.6 million.

  42.  Ofgem welcomes the companies' agreement to pay these customers and recognises that it goes beyond their legal obligations. Ofgem considers this to be a good outcome for customers.

Impact on the NEWSAC arrangements for sharing field staff

  43.  A number of companies have raised concerns that the use of comparative analysis in determining the disputes may undermine future emergency co-operation through the NEWSAC arrangements, whereby companies loan each other field staff. Ofgem considers that the efficient use of resources across the industry will tend to compress the range of times taken to restore customers' supplies, rather than increase them. This would reduce the overall length of power cuts and would continue to be in the long-term interest of companies and customers.

E.  DEVELOPMENT OF INTERIM AND LONGER-TERM ARRANGEMENTS FOR EXCEPTIONAL EVENTS

Background

  44.  During initial work on the distribution price control review and ongoing work on the determination process Ofgem found important weaknesses in the current standards of performance arrangements and in particular the application of exemptions:

    —  there is a lack of clarity in incentives to electricity distribution companies;

    —  there are delays in compensation reaching consumers;

    —  there is confusion for consumers about whether compensation is payable; and

    —  the determination process can be highly resource intensive for both Ofgem and energywatch.

  45.  To address these issues, Ofgem has begun to consider new arrangements to be introduced from April 2005, as part of the price control review. This work is described below.

  46.  However, as there is 18 months between now and April 2005, including two winters, Ofgem considers that it is important to put in place interim arrangements to cover events before the next price control, and avoid the problems encountered following last year's storms. Ofgem consulted on this issue in its July consultation paper on the distribution price control review. [25]Responses to the consultation were due on 22 August and, following consideration of the responses, Ofgem intends to discuss the detail of such a mechanism with the distribution companies, energywatch and other interested parties with a view to having new interim arrangements in place by the end of October. The form of the interim arrangements will depend on the outcome of this consultation process, and an agreement being reached with the distribution companies, but Ofgem's current thinking is outlined below.

Possible form of the interim arrangements

  47.  As noted in paragraph 24 above, the standards of performance exemptions were introduced in recognition of the fact that there are some events outside the control of companies that prevent them from restoring customers' supplies in the relevant timescales. Ofgem's intention in developing interim arrangements is to ensure customers receive more rapid payments following exceptional events whilst maintaining appropriate incentives for supply restoration. Such interim arrangements can only be introduced with the agreement of the companies or by changes to the Statutory Instrument. Ofgem's preferred option for these arrangements would be to proceed by agreement, which will require that the new arrangements do not expose the companies to materially increased risk.

  48.  In order to ensure that customers receive appropriate compensation for being off supply and that there are appropriate incentives for companies to restore customers promptly for different scale events, Ofgem considers that it may be appropriate to divide severe weather events into two categories:

    (a)  For smaller events (eg cases where only a few thousand customers are affected) the existing standards of performance arrangements would continue to apply.

    (b)  For larger events (for example cases where more than 5% of a company's customers are affected) companies would waive their right to claim an exemption for power cuts above a certain duration and would instead pay out all valid claims for compensation on a pre-agreed basis.

  49.  The electricity distribution companies would then seek recovery of compensation costs for the larger events through the price control, which would be spread across all consumers. Ofgem would need to review whether it was appropriate for a company to recover all or some of the costs associated with meeting the compensation claims. This could be based on an assessment of the company's performance both in terms of designing and maintaining the network and restoring customers' supplies once they had been interrupted, including the extent to which delays in restoration were beyond the companies' control.

  50.  Ofgem is currently working on developing the detail of the interim arrangements and considering alternative approaches such as rules relating the proportion of compensation recovered to the time taken to restore customers' supplies.

Arrangements for 2005-10

  51.  As part of the price control review process Ofgem is reviewing quality of supply incentives and Standards of Performance generally, including the exemptions regime, to seek ways of providing more clarity and improved incentives to companies.

  52.  Ofgem has commissioned a customer survey to assess customers' expectations of performance and willingness to pay for improvements. Fieldwork has now been completed for the first phase of this survey and Ofgem intends to publish the findings in September 2003. The second phase of the survey, which will include the detailed assessment of willingness to pay for improvements, will be conducted in early 2004 and the results published in May 2004.

  53.  Ofgem has appointed consultants to review the technical characteristics of previous exceptional events. The consultants have collected extensive data from distribution companies in respect of previous events, to ensure that revised arrangements are appropriate for a range of circumstances, and not just for those that occurred in October 2002. In addition, Ofgem and its consultants have held initial discussions with distribution companies and the Met Office about establishing a link between the weather and the impact of an event with a view to strengthening incentive arrangements.

  54.  Ofgem has also begun a process for requesting and analysing cost projections from the distribution companies as part of the DPCR4 work programme. As recommended in the BPI report, this will include an assessment of the costs and benefits of additional undergrounding and accelerated upgrading of overhead lines.

  55.  Ofgem is also reviewing the regulatory arrangements for provision of information by companies to customers, in the light of:

    (a)  the experience under the IIP arrangements;

    (b)  the failings of some companies in this regard in the October 2002 storms; and

    (c)  the importance placed on information by customers as demonstrated by the customer survey.

  56.  In line with the overall price control review timetable, in the summer and autumn of 2004 Ofgem will expect to discuss changes to the relevant Statutory Instrument setting out the Guaranteed Standards of Performance with the DTI and propose licence modifications to have effect from 1 April 2005. In the event of difficulties in implementing interim arrangements it may be appropriate to bring this timing forward.

F.  CONCLUSIONS

  57.  The October storms led to an unprecedented number of determinations and highlighted weaknesses in the current Standards of Performance arrangements such as delays in payment of compensation.

  58.  Ofgem believes that a better mechanism is required for handling such events in future. This should involve more rapid payment of compensation to customers who are badly affected and an agreed mechanism to assess how much of the cost should be passed through to customers in general.

  59.  In Ofgem's view the storms did not demonstrate any major weaknesses in the overall regulatory framework or in the incentives for distribution companies to invest. The evidence suggests that differences in performance are explained more by management and organisation than any lack of investment. As part of DPCR4, Ofgem is reviewing the incentives on companies regarding storm resilience generally and the provision of information to customers and expects to develop proposals to improve the regulatory framework in these areas.
