Achieving the targets
50. The Government has longstanding targets
for achieving 5 per cent of electricity production from renewables
by 2003, and 10 per cent by 2010. In addition, under the Renewables
Obligation a new target has been set10.4 per cent of electricity
sales to be from renewables by 2010. The latter differs significantly
from the longstanding 10 per cent target mainly because it does
not include large-scale hydro-electric power. It is therefore
significantly more challenging. The figure below shows UK performance
since 1990 in relation to these targets.

Trends, June 2002.
51. The figure shows that, as a percentage of total
generation, electricity from renewable sources has only increase
by just over 1 per cent in the last 10 years. In 2001, it actually
decreasedfrom a total of 2.8 per cent to 2.6 per
centdue to an unusually small contribution from
hydro.[72] It is already
certain that we shall miss the 2003 targetprobably by as
much as 2 per centas the Energy Minister confirmed in his
evidence to us.[73]
But even if the slightly greater rate of increase since 1996 is
extrapolated to 2010, on the present rate of progress we would
achieve only just over 5 per cent by 2010 against the longstanding
UK 10 per cent target. A number of witnesses endorsed this
view of the current rate of progress.[74]
52. Achieving the 10.4 per cent Renewable Obligation
target by 2010 represents an even greater challenge. Eligible
generation, which has only increased from 0.3 per cent to 1.5
per cent over the last 10 years, would need to increase from 1.5
per cent to 10.4 per cent in 8 years. It is of course possible
that there might be a step change in the rate of their deployment.
But given the planning difficulties and the uncertainties surrounding
the introduction of the main new policy instrumentthe
Renewables Obligation itselfthis is by no means
certain.
53. The Government is facing a similar situation
with regard to their other main environmental energy targetachieving
10 GW capacity of Combined Heat and Power (CHP) by 2010. Current
levels have stalled at below 5 GW and earlier modelling work by
Cambridge Econometrics indicated that it was unlikely to grow
to more than 7GW.[75]
In the 2002 Budget, the Treasury has introduced an exemption for
sales of electricity from CHP to the grid, and it has also addressed
the longstanding issue surrounding leasing and enhanced
capital allowances. The DTI have since commissioned further modelling
by Cambridge Econometrics which suggests that the target may now
be achieved, although the longawaited CHP strategy which
DEFRA finally launched for consultation in May 2002 contains no
new measures.[76]
54. The dire position of CHP in the last two years
has been widely acknowledged. One of the main companies involved
in developing CHP systems told us that it had axed all further
investment in this area,[77]
while the Ofgem August 2001 small generator review indicated that
CHP sales to the grid had slumped by over 60 per cent.[78]
In this context, it seems surprising to us that the relatively
minor changes the Government has announced are apparently going
to lead to the achievement of the target. We look forward to examining
the assumptions on which the Government has based this conclusion
when they are made available.
Achieving the target what
the reality would mean
55. Total sales of electricity in 200102 amounted
to 310 TWh. The DTI forecast that this will grow to 324 TWh by
2010which means that the RO target of 10.4 per cent
will require 33.6 TWh of electricity from renewables.[79]
By the end of 2000, generation from technologies currently eligible
under the RO totalled around 4.2 TWh. An increase in renewable
generation of some 29 TWh will therefore be required over the
next nine years if the target is to be metan increase
in capacity of over 3.2 TWh each year. The DTI has not set out
publicly the contribution it expects each renewable technology
to make, but modelling exercises have suggested that onshore wind,
offshore wind, eligible waste technologies, and biomass might
each contribute a quarter.[80]
56. To explore what this would mean in practice,
let us take the case of wind. In 2000, wind contributed 0.95 TWh
of electricity.[81] If
the 10 per cent target were to be met by wind alone, over three
times the total UK wind generating capacity currently available
would need to be installed each year. Evidence presented to us
suggested that, even to achieve half the target (ie 5 per cent)would
require one or two wind turbines to be erected every day between
now and 2010about 6000 turbines in total.[82]
This is clearly a daunting taskif only from an engineering
perspective. The possibility of setting up a relatively small
number of very large wind farms, probably offshore, along the
lines of that proposed for the isle of Lewis may be more manageable
both psychologically and operationally. The task is not impossiblerates
of build of over 1 GW a year have been achieved elsewhere[83]but
it would require substantial commitment to achieve. It also raises
serious concerns about the availability of sufficient engineering
resourcesboth human and mechanical - on the scale required
to implement such a task.[84]
57. We found less information available on the implications
of achieving the target in relation to other technologies. With
regard to biomass, DEFRA commented on poor takeup and expected
it to make only a limited contribution of 100 MW capacity to the
2010 target (in addition to biomass schemes undertaken under NFFO).[85]
Similarly, it is unclear what scope there is for expanding eligible
wasteeither through exploiting landfill and sewage
gas more, or through the growth of new waste technologies based
on pyrolysis, gasification, or anaerobic digestion. In any event,
it seems unlikely that these sources will contribute significantly
by 2010. As there is little expectation that PV or tidal energy
could contribute much on this timescale, we are left to conclude
that prospects for meeting the 2010 target depend mainly on wind.
