tonnes of stone, enough to fill almost three Olympic-sized swimming pools,
previously used to build a temporary access road and site accommodation for the
Triton Knoll onshore substation works, will be moved to the neighbouring
National Grid Viking Link interconnector project.
will save more than 58 tonnes of CO
2 in total, the equivalent of the
2 generated by heating 20 homes for one year. The saving has been
achieved through diverting the used aggregate from landfill, and reducing the
amount of new aggregate the Viking Link project will need to source meaning 675
additional lorry trips to and from each site will be avoided in total.
aggregate will be used to build an access road on Viking Link for the high voltage cabling works and converter station civil works.

the supply chain, to keep materials circulating and ensuring resources can be
can be recovered and reused, eliminating waste. I am delighted to see
such an inventive solution agreed between our customers. Not only will reusing
this material save CO
2 from the
quarrying process by reducing the amount of new aggregate we would need to
source, but through reducing the impact of construction traffic by more than 14,000
miles and around 675 lorry trips, air quality in the area will also be
Elmer, Project Director, Viking Link said: "We are really pleased to be
able to work with Siemens Energy and recycle the stone from Triton Knoll for
our Viking Link project. It not only reduces our carbon output but also
minimises disruption for local residents. We will continue to look for other
ways to reduce our carbon emissions wherever possible throughout the
construction of Viking Link."
Garnsey, Project Director for Triton Knoll and RWE, said: “We are committed to reducing
emissions and contributing towards sustainable development. Taking the time to
consider sustainable solutions to business challenges is environmentally
beneficial, and often also makes social and commercial sense. Collaborating
with Siemens Energy and National Grid to reuse material from the Triton Knoll
construction in another local project is a great example of this.“
