2.     Tariff Application and Charging Definitions
       Demand

       Billing and payment by settlement class

2.1    The following paragraphs are provided to help you to understand our Settlements
       (Supercustomer) related tariffs and their structures, as shown in the Company’s
       Market Domain Data Tables, and the conditions of use of these tariffs. The MDD set
       applicable to the Company is available from the Elexon at the following URL:

       http://www.elexon.co.uk/participating/marketdomaindata/

2.2    We will charge Supercustomer tariffs through two main charging components, which
       are Fixed Charges and kWh charges. There will only be one Fixed Charge applied to
       each MPAN or Connection Point to which you are registered. The kWh charge will be
       based on the active import registers on the metering system at your customer’s
       premises. More than one kWh charge will be applied to those tariffs which are classed
       as multi-rate.

      Southern Electric Power Distribution plc   -4-                           October 2008
2.3        The Tables within this document that relate to Supercustomer billed tariffs are:
       •        Table 3.1 for Profile Classes 1 and 2
       •        Table 3.2 for Profile Classes 3 and 4
       •        Table 3.5 for Preserved tariffs (Profile Classes 1, 2, 3 and 4)
       •        Table 3.6 for Unmetered Supplies (Profile Class 1).

      Notes on Domestic and Non Domestic Supplies

      The tariffs in table 3.1 refer to any single exit point serving any domestic, private
      residential premises.

      The tariffs in table 3.2 refer to non-domestic profile classes 3 – 4 for any single supply
      of electricity that is not used solely for domestic purposes in single, private dwellings.
      This includes private generators unless in our open special terms are appropriate.

       Site specific billing and payment

2.4    The following paragraphs are provided to aid your understanding of our Site Specific
       tariffs and their structures, as shown in Southern Electric Power Distribution’s Market
       Domain Data Tables, and the conditions of use for these tariffs. These charges will
       relate to a specific customer site, and are therefore billed on an individual site basis.
       The MDD set applicable to the Company is available from the Elexon.

2.5    Our charges will be based on a range of tariff components:
            •      A Fixed charge per site;
            •      kWh charges based on the active import registers as provided by the
                   metering system on site;
            •      Availability charges to reflect the site capacity usage

2.6    Our charges vary according to the voltage of the supply and application is limited on
       supply capacity and/or unit consumption. Where these charges are not appropriate
       due to special circumstances, the Company may offer alternative terms. Charges are
       shown exclusive of VAT, which shall be charged at the appropriate rate.

2.7    The tables within this document which relates to legacy HV Special and EHV Site
       Specific tariffs are:
         •      Table 3.3 for NHH Maximum Demand Use of System Tariffs;
         •      Table 3.4 for HH Maximum Demand Use of System Tariffs;
         •      Table 3.5 for Preserved HH Maximum Demand Use of System Tariffs;

      Southern Electric Power Distribution plc     -5-                            October 2008
       Unmetered supplies

2.8    These tariffs are available for supplies, which the Company deems as being suitable
       as Unmetered Supplies. The criteria for deciding suitability are:

       a)            where it is financially or technically impractical to install meters or carry out
                     meter reading; or

       b)            where the load is small (individually less than 500 W, in the case of public
                     lighting less than 500 W per column) and the consumption is reasonably
                     predictable. Supplies where consumption is dependent on some factor,
                     temperature for example, or where the load could be easily be increased
                     without the knowledge of the Company, will not normally be allowed to be
                     connected without a meter.
2.9    Where we have agreed with the customer that the electricity will be unmetered the
       following appropriate charges would apply.

              (i)        Scale 1 - for supplies (exit points) where sufficient geographical detail is
                         provided for the apparatus to be located and audited.

              (ii)       Scale 2 - for supplies (exit points) where sufficient geographical detail is
                         not provided for the apparatus to be located and audited (a summary
                         inventory).

       We will make a charge for managing the auditing and quality of the inventories. The
       charge will be determined on a case by case basis.
       Authorised Capacity
2.10 Non Domestic Supplies PC3-4

       The non-domestic charges apply to single low voltage exit points which use less than
       70kVA and are whole current metered.

2.11 Non-Domestic LV and HV PC 5-8 and Half hourly charges

       These charges apply to single low voltage and high voltage exit points, unless in our
       opinion special terms are appropriate. The charges include a standing charge, an
       availability charge (and an excess availability charge if required) and unit rates.

       (i)    Availability charges

       The non-domestic LV and HV PC 5-8 and Half Hourly charges include an availability
       charge for an agreed maximum capacity. The maximum capacity is in kVA as agreed
       from time to time between the customer and us. The maximum capacity is based on
       the maximum power requested and the capacity we can provide. The availability
       charges apply continuously through the year based on the agreed maximum capacity.

       Where a new or larger connection is provided, we will not normally allow the customer
       to reduce the maximum capacity for the first five years.

       Even if the customer no longer needs the supply during the initial five years, the
       customer will still be legally responsible for the balance of the availability charges.

       (ii)   Excess availability charges

      Southern Electric Power Distribution plc       -6-                             October 2008
        The customer can request us to agree an excess capacity outside the Peak Period
        (see Definitions) which will be charged at reduced rates. Additional charges for the
        extra control and metering equipment may be payable.

2.12      Maximum Capacity

        We will charge in blocks for Maximum Capacity.

            First block                                             15 kVA
            From 15kVA to 100kVA                  in blocks of      5 kVA
            From 100kVA to 250kVA                 in blocks of      10 kVA
            From 250kVA to 500kVA                 in blocks of      25 kVA
            From 500kVA to 1000kVA                in blocks of      50 kVA
            Above 1000kVA                         in blocks of      100 kVA

        If the maximum demand in any month is greater than the agreed Maximum Capacity,
        we will apply the availability charges to a suitable higher block for at least 12 calendar
        months and until the Maximum Capacity is reviewed. If the demand measured is in kW
        only we will assume the power factor is 0.95 unless the customer proves otherwise.
        The terms Available Capacity and Authorised Capacity may also be used in the above
        context and shall be construed accordingly.

2.13      Non-Domestic Site-specific charges.

        Where the Company, after evaluation of the characteristics of the supply and
        connection made, accepts that none of the categories of standard charges applies,
        charges for these connections will be determined on a site-specific basis. Normally the
        Loss Adjustment Factors (LAFs) will also be site-specific. Details of the charges and
        LAFs are available on request.
        Extra High Voltage Supplies
2.14 EHV sites are allocated site specific DUoS charges. EHV sites are defined in Special
     Condition Part B of the Electricity Distribution Licence, as sites connected to our
     distribution system at a voltage of higher than 22kV or at a substation with a primary
     voltage of 66kV or above. In practice, this means sites with exit points at 132kV,
     66kV, 33kV, and 22kV or at a 132/11kV or 66/11kV substations.
        Reactive Power Charges
2.15 In respect of loads with power factors, which fall outside the range of 0.8 lagging and
     unity, any specific conditions related to the power factor will be stated in the
     Connection Agreement.
        Preserved Charges
2.16 The preserved charges are only available to customers at premises where White Meter
      or Off-peak charges applied on 31 March 2008 and are not available to other or new
      customers. The preserved charges cannot be transferred to a different property. The
      charges include a daily standing charge and a single unit rate.

        Off-peak charges normally exist as part of a package, which includes unrestricted
        supply to the customer. The unrestricted element will normally be charged under
        Unrestricted, LV or HV. The standing charge in respect of high voltage supplies are
        determined on a site-specific basis.



       Southern Electric Power Distribution plc     -7-                          October 2008
     Generation
     Generation supplies
2.17 Generators applying for Connection after 1 April 2005 are liable for GDUoS, such
     charges applying to single EHV, HV and LV entry points. Where the generator also
     imports energy from the distribution system, the appropriate demand tariffs will apply.
     The GDUoS £/kVA charge will be levied on the export capacity specified in the
     generator’s connection agreement. At this stage, no charges will be made for
     generators connected at non half-hourly metered sites.

     Out of Area Networks
2.18 Where the Company operates distribution networks outside its distribution services
     area, it will charge any demand connections on those networks. The charges are
     included in this statement. In any such out of area networks, the metering functionality
     requirements will generally be those published by the host DNO. Where no such
     metering functionality requirements are published by the host DNO, those detailed in
     Table 3.9 shall apply.

     A.        Domestic Supplies
     The following charges apply to any single exit point serving domestic private
     residential premises.

     DUoS charge codes: xx1, xx2 where xx identifies the embedded distribution system(s)
     in a particular host DNO area.

     B.        Non Domestic Supplies

     The following non-domestic charges apply to single low voltage exit point which use
     less than 70kVA and whole current metered.

     DUoS charge codes: xx3, xx4 where xx identifies the embedded distribution system(s)
     in a particular host DNO area.

     The following non-domestic charges apply to single low voltage exit point which use
     equal to or greater than 70kVA and all CT metered exit points.

     DUoS charge codes: xx0, xx5, xx6 and xx9 (where appropriate) where xx identifies the
     embedded distribution system(s) in a particular host DNO area.

     Availability charges

     Where the non-domestic charge includes an availability component the charge will be
     based on the maximum capacity. The maximum capacity is in kVA as agreed from
     time to time between the customer and us. The maximum capacity is based on the
     maximum power requested and the capacity we can provide. The availability charges
     apply continuously through the year based on the agreed maximum capacity.

     Where a new or larger connection is provided, we will not normally allow the customer
     to reduce the maximum capacity for the first five years.

     Even if the customer no longer needs the supply during the initial five years, the
     customer will still be legally responsible for the balance of the availability charges.




    Southern Electric Power Distribution plc   -8-                           October 2008
 Maximum capacity

 We will charge in blocks for maximum capacity.

  From 70kVA to 100kVA                in blocks of      5 kVA
  From 100kVA to 250kVA               in blocks of     10 kVA
  From 250kVA to 500kVA               in blocks of     25 kVA
  From 500kVA to 1000kVA              in blocks of     50 kVA
  Above 1000kVA                       in blocks of     100 kVA

 If the maximum demand in any month is greater than the agreed maximum capacity,
 we will apply the availability charges to a suitable higher block for at least 12 calendar
 months and the maximum capacity reviewed. If the demand measured is in kW only
 we will assume the power factor is 0.95 unless the customer proves otherwise.

 Provision of metering equipment.

 For those customers who have a qualifying demand over 100kW, mandatory half-
 hourly code of practice metering is required for settlement purposes. Customers who
 have a qualifying demand less than 100kW and wish to settle on a half-hourly basis
 will require a code of practice half-hour meter.

 Charges for reactive power

 If the power factor falls outside the range of 0.95 lagging and unity and we do not ask
 the customer to correct it for technical reasons, we may charge for the kVArhs
 supplied.

 Unmetered Supplies

 Where we have agreed with the customer that the electricity will be unmetered the
 appropriate charges detailed in Table 3.6 would apply. The charges apply to supplies
 (exit points) where sufficient geographical detail is provided for the apparatus to be
 located and audited.

 We may make a charge for managing the auditing and quality of the inventories. The
 charge will be determined on a case by case basis.

 The charges shown in Table 3.6 do not include pseudo half-hourly Meter
 Administration charges or the Load Research charges (as agreed from time to time)
 which are also payable where appropriate. Details are available on request.

Notes to Table 3.8: Metering Functionality and Data Requirements
   1. In the event of the Supercustomer flow (D0030 - Non Half Hourly DUoS Report) not being delivered to the Company, the User shall
      provide that portion of the User's Supercustomer flow which contains the sites supplied within the Company's authorised area.
   2. Restricted kVA MD is provided on request and subject to Connection Agreement.
   3. For Half-hourly Metering Outside Settlement Timescales (MOST) it is anticipated that data would be received within 3 working days of
      meter read and for Metering Inside Settlement Timescales (MIST) it is anticipated that data will be received daily.
   4. Provision of Half Hour data shall be provided on flow D0275 - Validated Half Hourly Advances. Failure of the User's Data Collector to
      provide timely and accurate data will result in the production of an estimated bill based on historical data.

5.     SYSTEM LOSS ADJUSTMENT FACTORS
STANDARD LOSS ADJUSTMENT FACTORS
The total electrical losses on our distribution system are regulated in accordance with the
price control set out in the Licence. Suppliers should refer to the table of loss adjustment
factors to calculate the amount of electricity that they must provide. The same loss
adjustment factors (LAFs) are reflected automatically in the settlement system.
Role of Loss Adjustment Factors In the Supply of Electricity

Authorised Electricity Operators providing a supply of electricity from any entry point into the
Company’s electricity distribution network, including a generator entry point embedded in the
network or a supply point from the transmission network, will be required to demonstrate that
at all times the amount of electricity entering the network is sufficient to meet the supply in
accordance with the following adjustment factors.

Adequate supply can be demonstrated either by membership of the Balancing and
Settlement Code, or by provision of metering information on the relevant supply and load(s).
The table which follows indicates the factor by which supplies taken from the Grid Supply
Point must exceed the take at the exit point from the network, varying according to the time
of day, the season and the voltage of connection.

For premises connected at extra high voltage (at or above 22,000 volts or at a substation
with a primary voltage of 66,000 volts or above), special assessment will determine the loss
adjustment factor, which is relevant to the particular exit point. In some circumstances,
special low-loss equipment (such as transformers) may be available and can be included in
the calculation. Loads with power factors, which fall outside the range of 0.8 lagging and
unity, may also require special assessment.

Role of Loss Adjustment Factors In the Generation of Electricity
For generators embedded in the Company’s electricity distribution network, the output of the
generator will be grossed up to the equivalent of grid supply point supplies in a way which
conforms with the factors provided below. Account will be taken of the individual
characteristics and location with regard to the real electrical flows on the network, including
any losses on the connection into the Company’s electricity distribution network.

7. GLOSSARY OF TERMS
7.1      The following definitions are included to aid understanding.

Act
The Electricity Act 1989 as amended by Utilities Act 2000, the Sustainable Energy Act 2003
and the Energy Act 2004.


Authorised Capacity
means the capacity of supply expressed in kilovoltamperes (kVA), requested by the
Customer or authorised by the Company. Where a new or larger connection is provided, we
will not normally allow the customer to reduce the maximum capacity for the first five years
(ten for generator connections). Even if the customer no longer needs the supply during the
initial five years (ten for generator connections), the customer will still be legally responsible
for the balance of the availability charges. The terms Available Capacity and Maximum
Capacity may also be used in the above context and shall be construed accordingly


Authority
The Gas and Electricity Markets Authority (GEMA) – the regulatory body for the gas and
electricity industries established under section 1 of the Utilities Act 2000.


BSC
Balancing and Settlements Code


Chargeable Capacity
means the Authorised Capacity of the supply expressed in kilovoltamperes (kVA) or such
higher capacity as may be determined from the recorded peak demand in kilowatts (kW) in
the month of the account, and the associated power factor. Whenever the Chargeable
Capacity in a month exceeds the Authorised Capacity, the Authorised Capacity will be reset
to the higher figure until further notice.


Clocktime
means Greenwich Mean Time (GMT) in the winter and British Summer Time (BST) in the
summer as appropriate for the time of year.


CT
means Current Transformer.


Day
means all hours other than Night.

2 of the Company’s Distribution Licence.


Evening and weekend
means times other than Night or Weekday day.


Excess Capacity
means the agreed additional capacity in kVA normally kept available outside the Peak
Period.


High Voltage
means a pressure of more than 1,000 volts and less than 22,000 volts at the customer's
terminals


IDNO
means a party that holds a Distribution Licence in which Section C of the standard
distribution licence conditions does not have effect, whether or not that party is also engaged
in the supply or generation of electricity.


Low Voltage
means a pressure of not more than 1,000 volts at the customer's terminals.


Maximum Capacity
means the agreed capacity normally kept available, based on the maximum kVA required, for
electricity flow into the premises.


Month
means the period of around 30 days between normal meter reading dates.


Night
means generally a period of 7 or 8 hours daily between 11pm and 9 am GMT or Clocktime as
appropriate for the charge structure. The switching times may change from time to time.
