Dismantling the Gas Holders
WelcomeWelcome A plaque bearing the name of Gas Holder No. 1’s maker, S. Cutler and Sons of Millwall.
National Grid is dismantling its gas holders and clearing its former Clarendon Road Gasworks site.
The site is no longer used for storing gas and the gas holders have been decommissioned. We are now on site preparing to begin dismantling and remediation works so that the site can be brought back into beneficial use.
At this event you can find out about our project and the work that is now underway. If you have any questions or would like any further details, our experts will be happy to talk to you.
National Grid’s role is to connect people to the energy they use. We own and manage the energy network to which many different power sources are connected; our systems keep homes, offices and factories across the county going.
Over the years we have accumulated a number of sites related to energy industry but also shops, offices, depots and residential properties. This includes around 400 former gasworks sites, one of which is the Clarendon Road site. Today we are looking at how we can bring these sites back into use and in London, this means providing space for much needed new homes.

Dismantling the Gas Holders
An artists impression of the previously consented outline masterplan.
In March 2012, National Grid was granted
planning permission to redevelop our
redundant Clarendon Gasworks site, as part of
the Haringey Heartlands regeneration scheme.
The Haringey Heartlands scheme once completed will form a key part of the London Borough of Haringey’s regeneration goals for the future.
In March 2014, National Grid was granted planning permission for an amendment to the 2012 permission to allow the demolition of the gas holders, site preparation and construction of the pressure reduction station in advance of the submission of the reserved matters applications for future redevelopment. These works were known together as the Site Preparation Works. The dismantling of the gas holders is the first step towards bringing the land back into beneficial use.
Once National Grid has completed the dismantling and site remediation works, we will hand over to a development partner who will bring forward the redevelopment of the site.
The Story So Far

Dismantling the Gas Holders
A satellite view highlighting the planning application boundary (orange) and site preparation works (blue).
The site is located on land situated between
Hornsey Park Road, Mayes Road, Clarendon
Road and the mainline from King’s Cross.
Haringey Council has earmarked the site for regeneration since 2005.
Since the dismantling of Gas Holder No.2 in the 1970s, the site is occupied by Gas Holder No. 1, Gas Holder No.3 and other gas infrastructure in the east of the site, the former Haringey Call Centre building, a car park and car compound in the north and an area of vacant land in the south.
The remaining gas holders both have an external frame that supported their tanks as they rose out of the ground. Metal Guides set into the back of each frame’s columns would guide that tank as each segment rose. For this reason they are described as being column guided.
The Site’s History
The gas holders originally stored gas produced by the Hornsey Gas Company which was established in 1857 due to a rise in demand for gas to support residential growth in the borough.
The gasworks was first established in 1866 on land just outside of the current site boundary. Following the Hornsey Gas Order of 1884, the gasworks expanded to include the present Clarendon Road site.
After the discovery of North Sea oil and gas reserves, the need for gasworks rapidly diminished. In 1949, the Clarendon Road Gasworks site was passed onto the North Thames Gas board but it was closed in 1957 owing to its small size. Gas Holder No.2 was dismantled in the 1970s, leaving the two remaining gas holders and some other buildings on site.

Dismantling the Gas Holders
Preparing the Site
From 30 November 2015, our team have been on site carrying out preparatory work. The key elements to this preparatory work includes:
• Setting up environmental monitoring
equipment
• Putting up hoardings around the site
• General site clearance
• Japanese Knotweed treatment
• Setting up a water treatment plant
Our working hours are restricted to between 08:00 – 18:00 Monday to Friday and we have permission to work on Saturdays between 08:00 – 13:00, should the need arise, though we do not anticipate doing so.
Once the team has prepared the site, the dismantling of the gas holders will begin in the spring.
The Dismantling Work
The dismantling of the gas holders is scheduled to begin in March 2016 and will be complete in November 2016.
The gas holder dismantling process includes:
• Fencing off the gas holder for safety• Removing and cleaning any remaining
sludge and water from the tank reservoir
at the bottom of the holder
• Dismantling the gas holder’s tank
and removing its resting platform
• Infilling the empty tank left by the gas holders
• Removing the gas holder frame
We will also be dismantling and removing other disused infrastructure features around the site.
We want to ensure that the community is fully informed about the works and will be providing more information on the dismantling process as it progresses.

Pressure Reduction Station
What is a PRS?
Pressure Reduction Stations (PRS) are located in the majority of towns and villages.
A PRS:
• Lowers the pressure of gas in the pipe
network so it can be used in homes
and at work
• Comprises of below ground pipes and above
ground kiosks
• Safely connects pipe systems that operate at
different pressures• Includes equipment that monitors pressure
and allows safety inspections
• Is suitable for residential areas
Existing PRS equipment
The PRS is currently located near the gas holders, in low kiosks, that sit within a secure walled compound accessed from Hornsey Park Road.
Permission for the relocation of this equipment to two different parts of the site was granted as part of the outline masterplan consent in 2012. However, we are now able to relocate it the PRS equipment to a different, single location on the site and will therefore be submitting a further application to Haringey Council for permission to relocate the PRS.

Relocating the PRS
Relocating the PRS
The relocation of the existing PRS was approved as part of the 2012 planning permission. However, following changes to the requirements of gas infrastructure, the location and sizes of the PRS are no longer appropriate. National Grid will be submitting a ‘Section 73’ planning application to vary the location of the PRS.

Relocating the PRS
A parameter plan highlighting the proposed location of the new PRS in yellow.The new PRS location
The proposed new location of the PRS is next
to Hornsey Park Road and therefore has direct
access to the road for periodic maintenance
visits. The new location means that the PRS
can easily connect to existing infrastructure.
The new PRS will replace previously proposed mews houses and vehicular access point to the site and enable the provision of a pocket park for the local community.
Benefits of the new location• The relocation allows us to replace existing,
old equipment; ensuring gas can be supplied
to local homes and businesses long into the
future
• The new PRS will take the place of the
previously proposed mews homes
• Enables the provision of a new pocket park
which will include the existing lime trees
• Vehicular access to mews houses no longer
necessary
We would like your views on our plans to move the PRS so please fill out a feedback from today.

We have started the preparation work on
site and the dismantling of the gas holders
themselves is due to start in January 2016.
The work is scheduled to be complete by
November 2016. We will be updating our
site neighbours at each project milestone.
Once all of our works are complete and our development partner identified, it will then be in a position to commence developing the site to deliver the Haringey Heartlands scheme.
