Todd Energy receives carbon credits
for generating electricity for the national grid. In a
new cogeneration project officially opening today at Todd
Energy's McKee plant near Tikorangi in North Taranaki,
what would otherwise be waste gas is being used to generate
enough electricity and hot water to power 2000 houses
annually. In a separate project the plant will be
generating enough electricity to power a further 9000 homes
by December 2008. Todd Energy's managing director,
Richard Tweedie said: "With the power crisis threatening
the stability of New Zealand's energy supply, this project
is an excellent example of how cogeneration technology
maximises plant efficiency, using waste gas to deliver
electricity to the national grid and hot water for use at
the plant".
"This project also illustrates the type of
thermal generation that is clearly in the national interest
and should be encouraged by Government policy, but
unfortunately this is not the case". "Todd Energy is
always looking for opportunities to develop cogeneration
projects but is hesitant to do so given the Government's
intentions to ban thermal generation in excess of 10MW for
10 years", stated Mr. Tweedie. The cogeneration units are
driven by internal combustion engines designed specifically
to run on waste gas, which is an unavoidable by-product of
processing natural gas to pipeline specification sales
quality. This gas is sourced from a waste stream that was
previously flared into the atmosphere. The units will
generate 2 MW of electricity which is exported to the local
grid. In a separate project, the further three units that
will be operational in December will generate an additional
9 MW of electricity using gas sourced from the Mangahewa
Field.
Exhaust heat from the initial two generation units
will also be recovered to pre-heat water for the plant's
hot water system - a vital component in processing McKee
crude due to the oil's waxy nature. The hot water
produced is equivalent to providing energy to another 2000
households annually. Todd Energy has made significant
investments in renewable generation developments and is the
largest generator of electricity in New Zealand from
efficient gas-fired co-generation facilities, including
Whareroa, Edgecumbe, Kapuni and Southern Landfill in
Wellington, where landfill gas is used to generate
electricity. The 100% New Zealand owned energy producer
uses cogeneration technology to maximise energy efficiency
at commercial and industrial sites which ultimately helps
reduce New Zealand's greenhouse gas emissions.
Mr.
Tweedie commented: "We are very pleased that this project
has received carbon credits (Carbon Emission Reduction
Units) from the Government in recognition of the greenhouse
gas emissions reductions achieved". To design a viable,
long term solution to managing waste gas produced at the
McKee Plant, the project had involved the generation
expertise of Todd Energy subsidiary Bay of Plenty Energy
teamed up with the specialist engineering knowledge of
production team based at the Todd Energy offices in New
Plymouth.
