What is a CSS?

The energy market regulator, Ofgem, requires the six major energy suppliers in the UK to publish a CSS each year. The CSS sets out the revenues, costs and profit/losses for each segment in a specific template, to make sure that the performance of each energy company can be easily compared. It includes the results of all RWE entities in the UK that held an electricity generation, electricity supply or gas supply licence, and engaged in the activity of electricity generation or gas/electricity supply during a financial year.

To comply with the Ofgem guidelines, results from certain activities are omitted from the CSS. For example, the UK Generation segment operates a portfolio of combined heat and power plant (CHP), which do not require a generation licence. Similarly, the activities of the Generation Services business in the Supply segment, which performs non supply-related activities, are also excluded. These are referred to as "out of scope" activities.

The consequence of these and other adjustments necessary to comply with the Ofgem guidelines, means that the Earnings Before Interest and Tax contained in our CSS is not directly comparable with the segmental operating result published in the RWE AG and innogy SE Annual Reports. To help explain the differences between the two, a detailed reconciliation is contained within the CSS, which clearly sets out what the variance is, and why it arises.

Since 2014, Ofgem has required that the CSS be subject to independent audit, and this has been completed by PricewaterhouseCoopers LLP.

The RWE - UK Generation and Npower Supply CSS for 2018 summarises the revenues, costs and profits or losses of the generation and supply businesses, covering the 12-month period ending on 31 December 2018.

The RWE - UK Generation and Supply CSS for 2014 covers the 12-month period ending on 31 December 2014.

The CSS sets out the revenues, costs and profit/losses for each segment in a specific template, to make sure that the performance of each energy company can be easily compared. It includes the results of all RWE entities in the UK that held an electricity generation, electricity supply or gas supply licence, and engaged in the activity of electricity generation or gas/electricity supply during 2014.

To comply with the Ofgem guidelines results from certain activities are omitted from the CSS. For example, the UK Generation segment operates a portfolio of combined heat and power plant (CHP), which do not require a generation licence. Similarly the activities of the Energy Services business in the Supply segment, which performs activities such as boiler installation and maintenance, are also excluded. These are referred to as "out of scope" activities.

The consequence of these and other adjustments necessary to comply with the Ofgem guidelines, means that the Earnings Before Interest and Tax contained in our CSS is not directly comparable with the segmental operating result published in the 2014 RWE AG Annual Report. To help explain the differences between the two, a detailed reconciliation is contained on page 16 of the CSS, which clearly sets out what the variance is, and why it arises.

The 2014 CSS has been subject to an independent audit by PricewaterhouseCoopers LLP. The independent auditor’s report to the Directors of RWE Npower Holdings Plc and its Licencees is included on pages 20 and 21.

An Executive Summary is included on pages 2 and 3 which sets out the key points on the 2014 CSS.

The RWE - UK Generation and Supply CSS for 2013 covers the 12-month period ending on 31 December 2013.

The CSS sets out the revenues, costs and profit/losses for each segment in a specific template, to ensure that the performance of each energy company can be easily compared. The CSS includes the results of all RWE entities in the UK that held an electricity generation, electricity supply or gas supply licence, and engaged in the activity of electricity generation or gas/electricity supply during 2013. This means the results from certain activities are omitted from the CSS – for example, the UK Generation segment operates a portfolio of combined heat and power plant (CHP), which do not require a generation licence from Ofgem thus its results are therefore excluded from the CSS: likewise the activities of the Energy Services business in the Supply segment, which performs activities such as boiler installation and maintenance, are also exluded. Ofgem refer to these as "out of scope" activities. In addition Ofgem has also published detailed guidelines setting out the basis on which specific items should be included or excluded from the CSS.

The consequence of these and other adjustments necessary to comply with the Ofgem guidelines, means that the Earnings Before Interest and Tax contained in our CSS is not directly comparable with the segmental operating result published in the 2013 RWE AG Annual Report. To help explain the differences between the two, a detailed reconciliation is contained on page 15 of the CSS, which clearly sets out what the variance is, and why it arises.

In 2012, the earnings before interest and tax (EBIT) of RWE npower was £326m. This is the combined figure of our generation and retail businesses in the UK.

Our generation business recorded an EBIT of £126m. Our supply of gas and electricity to domestic customers recorded an operating result of £131m, and the result of our non-domestic gas and electricity supply was £69m.

The increase in profit in 2012 compared to 2011 was mostly due to a substantial increase in electricity generation – 49% more than we generated the previous year. This was partly due to the fact our new £1 billion Pembroke Power Station became operational, and our Tilbury Power Station was converted from coal to run on 100% sustainable biomass.

We also recorded increased sales of gas, mostly due to the colder weather in 2012 than 2011. In total, npower supplied almost 50 billion KWh of electricity in 2012, and over 46 billion KWh of gas.

In accordance with the recently modified Standard Licence Conditions 19A of the Gas and Electricity Supply Licence and 16B of the Electricity Generation Licence, RWE npower has prepared and published its Consolidated Segmental Statement (CSS) for the year ended 31 December 2011.

Download the 2011 Consolidated Segmental Statement (PDF, 128KB)

RWE npower's CSS for the year ending 31 December 2010 is provided as required by Ofgem's Electricity and Gas Supply Licences Condition 19A and Electricity Generation Licence Condition 16B. These licence conditions require an explanation of how the revenues, costs and profits reported in the CSS can be reconciled to UK statutory accounts or to the consolidated group accounts.

In accordance with these licence conditions, the CSS is prepared from the individual statutory accounts of the legal entities of the RWE npower group that held a generation or supply licence and engaged in generation or supply activities during the year ended 31 December 2010. As RWE npower is exempt, under Section 400 of the Companies Act 2006, from preparing and filing Consolidated Financial Accounts, the CSS is an aggregation of these individual Statutory Accounts which are prepared under United Kingdom Generally Accepted Accounting Principles (UK GAAP). These Statutory Accounts are subject to audit by independent, external auditors. Information on the entities included in the CSS is detailed in Section 2 below and the full reconciliation to the underlying UK GAAP Statutory Accounts is provided in Section 5.

1. Background

Following the Office of Gas and Electricity Markets' (Ofgem's) Energy Supply Probe, one of the objectives of which was to create greater transparency of financial information, the energy regulator introduced a Financial Information Reporting Licence Condition into the electricity generation, gas supply and electricity supply licences on 21st October 2009.

Ofgem's Electricity Supply and Gas Supply Licences Condition 19A and Electricity Generation Licence Condition 16B require Relevant Licensees (in effect companies including affiliates) generating electricity and supplying electricity and/or gas to more than 50,000 customers to; "prepare and publish on their websites a Consolidated Segmental Statement in respect of information relating to the revenues, costs and profits of their activities in the generation and supply of electricity and gas".

The Consolidated Segmental Statement (CSS) must be prepared and published no later than six months after the end of the licensee's financial year.

RWE Npower plc (the Company) and its subsidiary companies meet the criteria. Therefore the Company has prepared and published the CSS in accordance with the licence conditions for the year ended 31st December 2010.

2. Scope of entities included in the template

The Consolidated Segmental Statement (CSS) aggregates the revenues and costs attributable to the generation, electricity and gas supply activities of all subsidiaries and affiliates of RWE Npower plc that held either; an electricity generation, an electricity supply, or a gas supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2010.

RWE Npower plc (the Company) directly owns and manages a fleet of ten fossil fuel fired power stations located across England and Wales. Through its subsidiary companies it also:

  • Operates a small fleet of Combined Heat and Power (CHP) plants.
  • Manages and operates the supply of gas, electricity and related home and energy services to domestic and non-domestic customers.

The ultimate parent company is RWE AG, a company incorporated in Germany.

The list of legal entities that held a generation or supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2010 is summarised in the table below:

Legal entity name Registered number
RWE Npower plc 3892782
Npower Cogen Trading Ltd 2745602
Npower Ltd 3653277
Npower Commercial Gas Ltd 3768856
Npower Gas Ltd 2999919
Electricity Plus Supply Ltd 5199936
Gas Plus Supply Ltd 5199935
Npower Northern Ltd 3432100
Npower Direct Ltd 3782443
Npower Yorkshire Ltd 3937808

The operating assets of Npower Cogen Trading Ltd were sold to a third party on 3rd March 2010. The CSS incorporates the earnings of the entity (that specifically relate to the generation and supply of electricity) up to the date of sale of the assets. Following the disposal the entity did not engage in any trading activity and was dormant for the remainder of the year.

Some of the legal entities listed above also engage in commercial activities that do not relate to the generation of electricity or the supply of gas/electricity to domestic and non-domestic customers. We refer to these activities as "out of scope" and the revenues and costs attributable to these activities are excluded from the CSS. Examples of such "out of scope" activities include:

  • Home Energy services including boiler installation and maintenance.
  • Engineering and technical consultancy provided to third parties.

The CSS does not include subsidiaries of RWE Npower plc that hold either electricity generation or gas/electricity supply licences but which were dormant and had no trading activities during the year ended 31st December 2010.

3. Treatment of joint ventures

The company has a 50% Joint Venture interest in Horizon Nuclear Power Ltd, a company engaged in the development of a new generation of nuclear power stations in the United Kingdom. The Joint Venture Company does not hold a generation or supply licence and has no trading activities relating to the generation or supply of electricity. Accordingly the Company's share of the profit/loss of the Joint Venture Company is not incorporated in the template.

4. Revenues, costs and profits

As already referenced the CSS is an aggregation of the individual Statutory Accounts of the relevant legal entities that hold a generation or supply licence which engaged in generation or supply activities in the year ended 31st December 2010.

4.1 Generation - Revenue from the sale of electricity and gas

Our Generation business transfers capability to RWE Supply and Trading GmbH (RWEST) via an arms length asset tolling agreement.

In exchange for a capability fee, the asset tolling agreement provides RWEST in general with the option to deliver fuel to our power stations and have this converted into electricity. The fee is based on the option value derived from the forward markets at the time of the capability transfer. Transfer typically takes place 1 to 2 years ahead of time.

Thus, the bulk of the revenue of the business represents the sale of asset capability rather than the sale of electricity.

Other elements included within this category comprise post option income, ancillary services and balancing mechanism income and CHP electricity sales.

Other revenues

The main element relates to other revenues from CHP stations that hold a generation supply licence.

Electricity/gas costs

As described above, under the asset tolling agreement operated in the UK, the Generation business does not procure gas or coal. Therefore fuel purchase costs principally relate to CHP generation activities, which are outside the asset tolling agreement.

Other direct costs

Primarily relates to carbon certificate purchases and non-fuel direct costs relating to CHP generation. In accordance with guidance issued by Ofgem in relation to the 2010 CSS template, Balancing Services Use of System Charges (BSUoS) have been identified and classified in other direct costs.

Indirect costs

Comprise of directly attributable station operating and maintenance costs and the Generation segment's share of common costs.

The basis of allocation of these common costs across the segments is described in section 4.3 below.

Generation plant impairment

This represents a £249m impairment loss in respect of certain of the Company's coal and oil fired generating plants. During the period through to expected closure of the plants there has been a sharp decline in the margins forecast to be earned on coal and oil generation due to fundamental changes in the UK energy market over this period.

As a consequence of these market factors the estimated recoverable amount of the respective plant, on a continuing ("value in use") basis, was below the net book value of the assets.

WACO (E)/(G)

As described above, under the asset tolling agreement the Generation segment does not procure gas or coal. Therefore 'Weighted Average Cost of Fuel' is not applicable.

4.2 Retail - Revenues

Comprises of sales of electricity and gas to our domestic and non-domestic energy customers. Revenue is stated net of Value Added Tax (VAT) and discounts offered to our customers.

Electricity/gas costs

Reflects the costs of procuring electricity and gas to meet customer requirements. This includes the cost of any transmission and distribution losses suffered as well as balancing and shaping costs incurred.

These costs are captured at source between gas and electricity and then analysed between domestic and non-domestic based on the specific demand characteristics of the customer base. The weighted average cost differs between domestic and non-domestic because of different hedging approaches, particularly for flexible risk management products. The take up of these products varies between the domestic and non-domestic customers.

Our Retail business fulfils its wholesale commodity requirements via RWEST on an arms length basis.

Other direct costs

Comprises of:

  • Network costs, including electricity distribution/transmission and gas transportation costs and BSUoS charges.
  • Costs relating to the fulfilment of the Company's Carbon Emission Reduction Target (CERT), and
  • Community Energy Saving Programme (CESP) obligations.
Indirect costs

Costs that are directly attributable to a segment are charged to that segment in the CSS.

Customer service costs (such as billing, customer service and metering) are allocated across the segments on the basis of an activity based costing methodology.

Overheads and costs which are not directly attributable to supply segments are allocated between the domestic, non-domestic, gas and electricity segments in proportion to the indirect costs that are directly attributable from the costing methodology referred to in the point above.

Depreciation and amortisation

The depreciation and amortisation charge of the supply segments includes £70m of goodwill amortisation as charged in the individual Statutory Accounts. The amortisation relates to Goodwill carried in the balance sheets of Npower Northern Ltd, Npower Direct Ltd and Npower Yorkshire Ltd that arose on the acquisition of the Northern, Midlands and Yorkshire regional supply businesses during the late 1990's and early 2000's. The Goodwill is being amortised on a straight line basis over 20 years and will be fully amortised by 31st December 2021.

4.3 Common costs between generation and retail

The costs relating to Central Corporate functions and pension deficit repair payments have been allocated across the Generation and Supply segments on the basis of specific cost drivers that include headcount and membership of the pension scheme. The Supply segments share of the central corporate costs is allocated between its sub-segments on the basis described in section 4.2 above.

5. Reconciliation of CSS earnings before interest and tax (EBIT) to the UK statutory accounts for the year ending 31st December 2010

The table below sets out a reconciliation of the EBIT along with revenues (Turnover) and costs (Total Costs) for the Year Ending 31st December 2010 (as presented in the Consolidated Segmental Statement) to the aggregation of the Statutory Accounts of the legal entities detailed in Section 2 above.

As previously mentioned, RWE Npower Holdings plc, the holding company of RWE Npower plc, is exempt under Section 400 of the Companies Act 2006 from preparing and filing Consolidated Financial Statements. Therefore, the Consolidated Segmental Statement is an aggregation of the individual Statutory Accounts of the legal entities that held a generation or supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2010.

Excluded from the CSS EBIT are:

  • (£35m) of earnings from out of scope activities and transactions (see section 2.)
  • (£132m) of intercompany transactions. These are excluded as they do not relate to either generation or supply activities, and would be eliminated on full consolidation.
  • £54m of exceptional costs that do not directly relate to the ongoing activities of the Company's operations. They are of a one-off or non-operating nature and relate to activities such as organisational restructuring and staff severance.

6. Additional information to users of the CSS

As already described in Section 5 above, the CSS is an aggregation of the individual Statutory Accounts of the relevant legal entities.

The Company's contributions to its Defined Benefit (DB) pension schemes (including deficit repair payments agreed with the Pension Scheme Trustees) are recognised directly in the Statutory Profit and Loss Account as and when paid. This is because the Company cannot identify the respective share of the underlying assets and liabilities of its DB scheme on a reasonable and consistent basis across the various legal entities. Thus the DB pension scheme is accounted for as a multi-employer scheme under FRS 17 (Retirement Benefits) and therefore the contributions are charged directly to other operating costs within the Statutory Accounts (and within indirect costs within the CSS).

If consolidated accounts were prepared, the Defined Benefit pension schemes would have been accounted for as a single employer scheme under FRS 17. To assist users of the CSS in better understanding the impact of the different accounting treatment that would have been applied if consolidated accounts were prepared, we have summarised the impact on reported EBIT in the table below.

£M Generation Supply - electricity Supply - gas Total supply Memo total
Domestic Non-domestic Domestic Non-domestic
EBIT per CSS as reported (38) (148) 59 (6) 5 (90) (128)

Adjusted CSS EBIT (for info only) (22) (136) 63 4 6 (63) (85)

Since RWE AG (RWE npower's ultimate Parent Company) reports under International Financial Reporting Standards (IFRS), RWE npower reports its results to RWE AG under IFRS. The Operating result of the RWE npower group disclosed in the Annual Report of RWE AG for the year ended 31st December 2010 was Euro 272m (equivalent to GBP233m). The Operating result disclosed in the Annual Report is EBIT (earnings before interest, tax and amortisation) and excludes exceptional items. The main differences between the CSS template (which requires the reporting of EBIT) prepared under UK GAAP and the Operating result disclosed in the RWE AG Annual Report are:

  • The inclusion on the face of the CSS template of the (£249m) impairment loss explained in section 4.1 above. The impairment loss is classified as an exceptional cost in the RWE AG Annual Report and is therefore not reflected in the Operating result.
  • The inclusion of UK GAAP amortisation in the Supply segment as explained in section 4.2 above. The CSS template specifically requires the inclusion of amortisation.
  • The accounting treatment applied to the Company's Defined Benefit pension scheme as described in detail in the paragraph above.

RWE npower's Consolidated Segmental Statement for 2009 (below) is provided as required by Ofgem's Electricity and Gas Supply Licences Condition 19A and Electricity Generation Licence Condition 16B.

1. Background

Following the Office of Gas and Electricity Markets' (Ofgem's) Energy Supply Probe, one of the objectives of which was to create greater transparency of financial information, the energy regulator introduced a Financial Information Reporting Licence Condition into the electricity generation, gas supply and electricity supply licences on 21 October 2009.

Ofgem’s Electricity Supply and Gas Supply Licences Condition 19A and Electricity Generation Licence Condition 16B require Relevant Licensees (in effect companies including affiliates) generating electricity and supplying electricity and/or gas to more than 50,000 customers to “prepare and publish on their websites a Consolidated Segmental Statement in respect of information relating to the revenues, costs and profits of their activities in the generation and supply of electricity and gas”.

The Consolidated Segmental Statement (CSS) must be prepared and published no later than six months after the end of the licensee’s financial year.

RWE Npower plc (the Company) and its subsidiary companies meet the criteria. Therefore the Company has prepared and published the CSS in accordance with the licence conditions for the year ended 31st December 2009.

2. Scope of entities included in the template

The Consolidated Segmental Statement (CSS) aggregates the revenues and costs attributable to the generation, electricity and gas supply activities of all subsidiaries and affiliates of RWE Npower plc that held either an electricity generation; an electricity supply or a gas supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2009.

RWE Npower plc (the Company) directly owns and manages a fleet of ten fossil fuel fired power stations located across England and Wales. Through its subsidiary companies it also:

  • Operates a small fleet of Combined Heat and Power (CHP) plants.
  • Manages and operates the supply of gas, electricity and related home and energy services to domestic and non-domestic customers.

The ultimate parent company is RWE AG, a company incorporated in Germany.

The list of legal entities that held a generation or supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2010 is summarised in the table below:

Legal entity name Registered number Electricity generation licence Electricity supply licence Gas supply licence
RWE Npower plc 3892782
Npower Cogen Trading Ltd 2745602
Npower Ltd 3653277
Npower Commercial Gas Ltd 3768856

Gas Plus Supply Ltd 5199935
Npower Northern Ltd 3432100
Npower Direct Ltd 3782443
Npower Yorkshire Ltd 3937808

Some of the legal entities listed above also engage in commercial activities that do not relate to the generation of electricity or the supply of gas/electricity to domestic and non-domestic customers. We refer to these activities as "out of scope" and the revenues and costs attributable to these activities are excluded from the CSS. Examples of such "out of scope" activities include:

  • Home Energy services including boiler installation and maintenance.
  • Engineering and technical consultancy provided to third parties.
  • Meter reading services provided to third parties.

The CSS does not include subsidiaries of RWE Npower plc that hold either electricity generation or gas/electricity supply licences but which were dormant and had no trading activities during the year ended 31st December 2009.

3. Revenues, costs and profits

As already referenced the CSS is an aggregation of the individual statutory accounts of the relevant legal entities that hold a generation or supply licence which engaged in generation or supply activities in the Year Ended 31st December 2009. The individual statutory accounts are prepared under United Kingdom Generally Accepted Accounting Principles (UK GAAP) and have been subject to audit by independent, external auditors.

3.1 Generation - Revenue from the sale of electricity and gas

Our Generation business transfers capability to RWE Supply and Trading GmbH (RWEST) via a fair valued “Asset Tolling Agreement”.

In exchange for a capability fee, the Asset Tolling Agreement provides RWEST with the option to deliver fuel to our power stations and have this converted into electricity. The fee is based on the dark/spark spread for 2009 derived from the forward markets at the time of the capability transfer. Transfer typically takes place 2 years to 1 year ahead of time.

Thus, the bulk of the revenue of the business represents the sale of asset capability rather than the sale of electricity.

Other elements included within this category comprise post option income, ancillary services and balancing mechanism income and CHP electricity sales.

Other revenues

The main element relates to other revenues from CHP stations that hold a generation supply licence.

Electricity/gas costs

As described above, under the asset tolling agreement operated in the UK, the Generation business does not procure gas or coal. Therefore fuel purchase costs principally relate to CHP generation activities, which are outside the asset tolling agreement.

Other direct costs

Primarily relates to carbon certificate purchases and non-fuel direct costs relating to CHP generation.

Indirect costs

Comprise of directly attributable station operating and maintenance costs and the Generation segment's share of common costs.

The basis of allocation of these common costs across the segments is described in section 3.3 below.

WACO (E)/(G)

As described above, under the Asset Tolling Agreement the Generation segment does not procure gas or coal. Therefore no Weighted Average Cost of Fuel is provided.

3.2 Retail - Revenues

Turnover (net of VAT) of electricity and gas sales to our domestic and non-domestic energy customers.

Electricity/gas costs

Reflects the costs of procuring electricity and gas to meet customer requirements. These costs are captured at source between gas and electricity and then analysed between domestic and non-domestic based on the specific demand characteristics of the customer base.

  • Our Retail business transacts the majority of its wholesale commodity exposure via RWEST on a fair value basis.
Other direct costs

Primarily reflect network costs including electricity distribution/transmission, gas transportation and balancing.

Indirect costs

Costs that are directly attributable to a segment are charged to that segment in the CSS.

Customer service costs (such as billing, customer service and metering) are allocated across the segments on the basis of an activity based costing methodology.

Overheads and costs which are not directly attributable to supply segments are allocated between the domestic and non-domestic segments on the basis of the outputs from an internal study that was undertaken to establish a methodology to apportion overheads to specific market segments. The costs are then allocated between gas and electricity on the basis of identifiable cost drivers which include metering points (MPANs).

Depreciation and amortisation

The depreciation and amortisation charge of the supply segments includes £73m of goodwill amortisation as charged in the individual statutory accounts.

3.3 Common costs between generation and retail

The costs relating to Central Corporate functions and pension deficit repair payments have been allocated across the Generation and Supply segments on the basis of specific cost drivers that include headcount and membership of the pension scheme. The Supply segments share of the central corporate costs are allocated between its sub-segments on the basis described in section 3.2 above.

4. Reconciliation of CSS earnings before interest and tax (EBIT) to the UK statutory accounts for the year ending 31st December 2010

The table below sets out a full reconciliation of the EBIT along with revenues (Turnover) and costs (Total Costs) for the Year Ending 31st December 2009 (as presented in the Consolidated Segmental Statement) to the aggregation of the statutory accounts of the legal entities detailed in Section 2 above.

RWE Npower Holdings plc, the holding company of RWE Npower plc, is exempt under Section 400 of the Companies Act 2006 from preparing and filing Consolidated Financial Statements. Therefore, the Consolidated Segmental Statement is an aggregation of the individual statutory accounts of the legal entities that held a generation or supply licence and engaged in electricity generation or gas/electricity supply activities during the year ended 31st December 2009.

Excluded from the CSS are:

  • Out of scope activities ie. activities of the legal entities that do not relate to the generation of electricity or supply of energy.
  • Dividends received from subsidiaries (as these do not arise from Generation or Supply activities) and exceptional costs. These exceptional costs do not directly relate to the ongoing activities of the Company’s operations in 2009. They are of a one-off or non-operating nature and relate to activities such as organisational restructuring or provisions in respect of potential claims or actions that have arisen.
Turnover Total costs EBIT
Total statutory EBIT, turnover and costs 7,615 (7,664) (49)
Removal of "out of scope" activities (241) 215 (27)
Removal of intercompany dividends and exceptional costs (5)
Total reported EBIT, turnover and costs 7,373 (7,455) (81)

5. Additional information to users of the CSS

As already described in Section 4 above, the CSS is an aggregation of the individual Statutory Accounts of the relevant legal entities.

The Company’s contributions to its defined benefit (DB) pension schemes (including deficit repair payments agreed with the Pension Scheme trustees) are recognised directly in the Statutory Profit and Loss account as and when paid. This is because the Company cannot identify the respective share of the underlying assets and liabilities of its DB scheme on a reasonable and consistent basis across the various legal entities. Thus the DB pension scheme is accounted for as multi-employer scheme under FRS 17 (Retirement Benefits) and therefore the contributions are charged directly to other operating costs within the statutory accounts (and within indirect costs within the CSS).

Generation Supply - electricity Supply - gas
Domestic Non-domestic Domestic Non-domestic
EBIT per CSS 145 (102) 25 (136) (13)
Impact of EBIT if DB scheme accounted for as such rather as multi employer scheme 60 27 26 18 4
Adjusted CSS EBIT (for info only) 205 (75) 51 (117) (9)
