BT Powering Ahead

BT Powering Ahead

Firstly, some facts about BTs power consumption

• In the last financial year we used 1.7TWh and
  this is likely to rise to 2.25TWh this year.
• We now have 2 million Broadband customers and
  this is increasing everyday.
• For every broadband customer we add to our
  network, increases our continuous load by 1.7 to
  2 watts.
• As you see we have a problem of rising
  consumption!

So how are BT powering ahead?

• We have initiated various energy saving
  programs...
• Replacement of inefficient components in existing
  Heat/Ventilation plant
• Installed half hour metering at our 6500
  operational buildings to manage out inefficiency
• Encouraged more Homeworking
• Buying Green Electricity where we can
• Latterly we are talking to equipment suppliers
  producing low energy designs.

But, we are now facing a major problem

• ..In the 2002 financial year, BT was ahead of
  schedule, sourcing 4.6 of its electricity from
  renewables (therefore exceeding its own target of
  3 and the interim annual target set for
  electricity suppliers through the Renewables
  Obligation). However, for the 2003 financial
  year, the amount of renewable energy sourced by
  BT dropped by over 50, from 93GWh to 45GWh
  (equivalent to 2.1 of total energy use). It has
  now become clear to BT that the 5 (by 2004) and
  10 (by 2010) renewables targets are not
  achievable given the current state of the
  market..

So what did we do?

• We commissioned Forum for the Future to
  investigate why the green energy is so scarce and
  they suggest
• A general shortage of supply in the market
• Heightened competition for what little supply
  there is available
• Significant green electricity price premiums
  undermining the internal business case
• Difficulties in securing long-term and
  price-stable contracts for renewable electricity
• Lack of transparency over the environment
  credentials of the available green tariffs

6
The Forum for the Future report recommended...

• 13 actions for government to enable a sustainable
  renewables market
• BT should commission a detailed audit of its
  estate (both land ownership and buildings) to
  assess the potential for installing its own
  on-site renewable generating capacity
• BT should work with a specialist broker
  organisation to explore the possibility of buying
  and retiring Renewables Obligations Certificates,
  thereby expanding the market
• BT should explore the potential to invest in new
  renewables projects through initiating
  discussions with a variety of specialist
  developers, possibly in partnership with an NGO
• BT should require greater assurance from its
  suppliers as to the provenance of the supply when
  purchasing renewable energy

Some Green Energy initiatives we are considering

• Embedded generation at our operational sites both
  rural and urban.
• Use of Bio fuels in existing standby generation
  plant and in new heating systems
• Use of new passive cooling technologies in our
  new 21st Century networks and associated nodes.

8
Embedded generation

• We looking at both Wind and Photovoltaics (PV)
• Wind
• The Carbon Trust are investigating our
  operational estate to find our best sites for
  wind generation
• At two sites in Cornwall we are piloting a new
  type of turbine designed by Wind Dam Ltd.
• We hoping to erect large Wind turbines at
  Goonhilly and other suitable sites across the UK
• We could be retro-fitting small WTs on our
  Microwave Towers

9
PV

• The costs of PV are prohibitive and payback
  periods are far too long at present
• We are however looking to clad a 21st Century
  Node with PV panels to assess the power
  integration of the technology
• We will be looking for funding/grants to help us
  with the costs

10
Winddam

• This is a new twist to an existing technology
  that is both silent and visually appealing
• It could well be a viable proposition in the
  urban environment
• But we cant claim enhanced capital allowance
  scheme on this product.
