New Houses In Tendring – Can Electricity Supply Cope?

Tendring has been ordered to plan for around 10,000 new houses by central government. Tendring district council proposes many should be built in coastal towns and surrounding villages.  Can the electricity supply cope?

There is a large electricity substation in Great Holland called Clacton Grid, which supplies Clacton, Frinton, Walton and surrounding villages.



The pylons which bring electricity to Clacton Grid come from near Manningtree, past Horsley Cross, Tendring and Thorpe to Great Holland.


Here is a map which shows the pylons approximate route.  A distance of at least 7 miles.



So can the existing electricity supply cope with the new houses?

If so there must have been excess capacity for many years.  Why???

If not will there need to be a new substation – where will it be built?

Where will the new pylons be put to supply this new substation?

Is there enough electricity generation capacity to supply new substation?  Or is this why government has arranged for Chinese to build and run a new nuclear power station at Bradwell?


Actually there is a case of over capacity being built.

You many have noticed there are rarely hose pipe bans in Tendring, even though the rest of country suffers.  My parents told me in 50s or 60s a large reservoir was built to supply a new town which was never built.

So when new houses are built we can have hose pipe bans like the rest of the country!

    Remember Jeremy that 172Mw is put into the grid here from the Gunfleet wind farm. Mind you it would be nice to know what the actual figure is from the wind farm.

    Thanks for your comment Trevor, sorry for being so slow to reply.

    There will not usually be 172MW being generated by Gunfleet wind farm as it depends on how much, if any, wind is blowing.

    Now you’ve prodded me I’ll do a post about this.

    But in the meantime a few facts and figures.

    Gunfleet wind farm uses Siemens SWT-3.6-107 whose maximum power output is rated at 3.6MW. There are 48 of them, 48 x 3.6MW = 172.8MW

    The power output of a wind turbine varies with the cube of wind speed.
    For the SWT-3.6-107 no power is produced below 3-5 mps (meters per second) around force 3. But with this little wind less than 0.5MW is generated.

    Maximum power is achieved at 15 mps (around force 7 – near gale)
    and cut out is at 25 mps (force 10 – full gale)

    Here is link to turbine specifications

    And this page has a graph showing how the power generated varies with wind speed

    172MW sounds a lot, in fact DONG claim it could power UPTO 100,000 homes.


    172MW is 172,000,000 watts. Divided by 100,000 means each home has an average of 1720 watts, or 1.72kw (kilo watts).

    Most kettles are 2 or 3 kw so DONG’s claim of powering 100,000 homes isn’t true if these homes are going to be allowed cookers and kettles.

    Even 50,000 homes isn’t really true either.

    People may think people won’t all boil there kettles at the same time. But they often do. The old CEGB used to monitor tv schedules as they new when there was an advertising break in Corrie or Crossroads (there’s a blast from the past) there was regularly a huge surge in demand for electricity as people boiled their kettles for a cuppa.

    Taking your comment another way

    Are you saying the wind farm was built so more homes could be built in Tendring!

    We are lucky enough to have an underground aquifer in Tendring – I have never heard about a large reservoir….
