Generating capacity
This section provides some more detail for
the generation capacity backgrounds for the
scenarios and outlines the key changes over the
period to 2032 in each of the cases.
2.4.1
Generating Capacity
Definition
The values shown within this section are only
for capacity that is classed as ‘transmission
capacity’. This is generally generation capacity
that is classified as ‘large’ 1 and therefore does
not include any small embedded generation.
Embedded generation not included in these
values is accounted for in the assessment of
transmission demand as discussed in the
Section 2.3.

2.4.2
Slow Progression 2012
This scenario has a lower emphasis on renewable
generation over the period. The key messages for
this scenario are shown below:
Gas capacity increases over the period to 2020
by 7 GW and to a total of 49 GW by 2032
showing a total increase over the period of
16 GW.
Growth in wind capacity is considerably slower
in this scenario in comparison to Gone Green
and Accelerated Growth and reaches 13 GW
by 2020 and 28 GW by 2032 (19 GW being
offshore wind), showing a total increase over
the period of approximately 22 GW (the vast
majority of this being offshore wind).
Other renewables excluding wind remain fairly
static over the full period to 2032 showing only
approximately a 300 MW increase.
Coal capacity shows a slower decline than
in the Gone Green scenario showing a
7 GW decrease by 2020 leaving 18 GW
of coal capacity. Between 2020 and 2032
coal declines further, to 4 GW by the end of
the period.
Nuclear capacity remains fairly static over the
period rising from 10 GW in 2012 to 13 GW by
2030 before falling back to 11 GW by 2032.
