MidAmerican
–
part
of
the
business
empire
of
investment
tycoon
Warren
Buffett
–
is
buying
the
stake
in
the
$1.8bn
plant
in
Yuma
County,
Arizona,
from
NRG
Energy.
The
plant,
which
is
being
built
by
First
Solar,
is
expected
to
be
complete
by
2014.
The
project
won
a
$967m
loan
guarantee
from
the
US
Department
of
Energy,
and
has
tied-up
a
long-term
power-purchase
agreement
with
utility
Pacific
Gas
and
Electric
for
all
its
electricity
production.
Subject
to
regulatory
approval,
the
deal
will
be
MidAmerican’s
second
foray
into
solar
this
month.
Financial
terms
were
not…
