and sewage waste, which
is cleaned and processed.
We are working with the
developers who own and
operate these plants to reduce
the cost and timescales
of their connections to
our networks.
Other innovative ways of
reducing costs include our
first high pressure plastic
pipeline. We are also working
with a range of parties to
develop bio-substitute natural
gas (BioSNG), which will
enable us to generate
renewable gas from a broader
range of feedstock, including
black bag domestic waste.
We are at the forefront of
‘greening the gas grid’, and
foresee a lot more progress
in this sector through the
RIIO period.
Cleaner gas
Around a third of the UK’s
greenhouse gas emissions
are associated with heat, the
majority of which is provided
by natural gas.
Decarbonising domestic
heat remains one of the
major challenges in society’s
energy trilemma, so our
Gas Distribution business
is developing sources of
renewable gas that can be
transported through our
existing networks. This
approach means we can
deliver low carbon heat
directly to people’s homes
without the need for costly
new infrastructure.
In 2015/16 we connected
12 new anaerobic digestion
plants to our network. These
plants generate renewable
gas from a range of organic
feedstock, including
agricultural by-products
