What we do and where we do it
We jointly own and operate transmission
facilities across upstate New York,
Massachusetts, New Hampshire,
RhodeIsland and Vermont. We own and
operate electricity distributionnetworks
inupstate NewYork, Massachusetts
andRhode Island.
We own and operate gas distribution
networks across the northeastern US
located in upstate New York, New York
City, Long Island, Massachusetts and
Rhode Island.
In focus:
3.5m
electricity consumers in
NewEngland and upstate
NewYork.
16bn
standard cubic metres of
gasthat we forecast, plan
forand procure annually.
3.6m
consumers receive services
from our gas distribution
networks, including 26,882
new gas heating customers
in 2014/15.
30 TWh
of electricity we forecast,
planfor and procure annually
across three states.
169km
(105 miles) of underground
cable, 520 transmission
substations and 644 distribution
substations we operate in New
England and upstate New York.
14,355km
(8,920 miles) of electricity
transmission system are owned
and operated by National Grid.
15 year PSA
We own and operate 50 fossil fuel-powered units on Long Island
that together provide approximately 3,800 MW of power under
contract to LIPA. Our Power Supply Agreement (PSA) with LIPA
is for 3,634 MW of capacity, comprising eight dual fuel (gas/
oil-fired) steam units at three sites, 11 dual fuel combustion
turbine units, and 27 oil-fired combustion turbine/diesel units.
Under a separate contract with LIPA, four dual fuel combustion
turbine units provide an additional 160 MW of capacity.
Market context
In the US, regulators are focused on system modernisation and the integration of new distributedenergy resources. In 2014 we
introduced Connect21, our thinking on advancing America’s natural gas and electricity infrastructure beyond its20th century
limitations, and creating a more customer-centric, resilient, agile, efficient and environmentally sound energy network. We are working
with policymakers, customers andstakeholders to transform the energy industrythrough initiatives such as GridModin Massachusetts,
Reforming the Energy Vision (REV) in New York, and Gas and Electric Infrastructure Safety and Reliability (ISR) plans in Rhode Island.
