A: One Supplier had
a lot more HH
registrations at the
October 2009 contract
round, resulting in
more Estimates being
submitted.
B: This drop in MSID
count is due to one
Supplier moving
MPANs from HH to
NHH.
C: This drop in MSID
count is due to
another Supplier
moving a few MPANs
from HH to NHH.
D: This drop is due to
the same Supplier as
in B moving more
MPANs from HH to
NHH.

2008 is due to the
number of Default
EACs for one Supplier
increasing over a
period.
B: The steady rise in
_J is due mainly to
one Supplier’s Default
EACs increasing. The
rise then sharp drop
in mid-July 2008 is
due to another
Supplier.
C: The fall in _J in

Erroneous Large EAC/AA’s Historical SEAE Market View
A: The large errors in
October 2008 are due to a
Supplier leaving the Market,
leaving a significant volume
of error in Settlement for this
period.
As this error affects most
GSP Groups, this spike will
also appear in most of the
following graphs. For this
reason, it will not be
highlighted within them.
