The project so far
Since 2002 Bristol City Council’s Energy Management
Unit (EMU) has been investigating the possibility of developing an on-shore
wind farm next to the Severn Estuary. The area is part of the industial estate
toe the north west of the city and was formerly occcupied by an fuel
tank farm. The site is owned by the Council and has the potential to house two
large wind turbines. To date, the EMU has self funded a 12-month wind speed
study, 12-month bird counts and wildlife investigations. The geo-technical
ground formations; possible radar implications and potential planning outcomes
are presently being investigated. All of this work has been secured from one
off bid funding. Having established that the project is practically viable the
financial implications, both capital and revenue, need to be investigated
before this development can continue.
The EMU is also being pro-active in reaching the BCC
target of 15% of electricity consumption coming from renewables by 2010.
Developing a wind turbine facility in Avonmouth is simply one step the EMU is
taking to achieve this outcome. Its
construction will lead to CO2 reductions of 5,160 tonnes equating to
17.8% of the council’s electrical consumption. This reduction together with the
7.5% already achieved by purchased green electricity would achieve 25.3%
reduction in the carbon emissions by the council, more than meeting the target
set for 2010. This development will therefore assist in improving the Quality
of Life for Bristol Residents.
The 12-month wind speed study has shown that the average
wind speed is viable for turbines. All the other consultations and studies that
have taken place show that the development would cause no negative effects on
the wildlife, nor release soil contaminates which remain in the soil after the
fuel
tanks were removed.
Garrad Hassan have designed a turbine layout for the
Avonmouth site. According to this layout the site can hold two turbines. They
have considered various designs of turbine with the most conservative being the
NM92. This has a hub height of 85m and a rotor diameter of 92m. If this
specification was chosen and two were erected on site, their energy generation
capacity would be 5.5MW.
NEXT STEPS:
Continue with various pieces of consultation work. These
include
·
Geo-technical
information for foundation of turbines
·
Radar/mobile
phone implications
·
Archaeological
status of site (only needs to be investigated again during construction)
·
Summer
bird counts on site
It is thought that radar can be affected by wind turbines
so both the local airfield and Bristol International Airports were informed
about the proposed development. Bristol International had no concerns about the
proposal, however the airfield, which is closer, did offer some objections. These objections
have been investigated further and the Civil Aviation Authority has been
consulted. The Airfield will have to prove why the development would be
detrimental. It is expected that any developer would assist in that process and
an independent consultant may need to be employed to aid in the process.
If the project succeeds then the electricity would be fed
into the National Grid or some could be used by local development. The
estimated cost of the project is £48,000 (approximately € 72,160). |
