Green Party London Assembly member Darren Johnson (pictured) said: “The problem with plans for the Olympics energy centre lies not with the centre itself, but with the targets it is being built to achieve.
“To only aim to provide 20 per cent of Games time and Legacy energy demand from local and on-site renewable energy sources respectively is to miss a huge opportunity to demonstrate carbon saving technologies.
“Instead, Olympic organisers should be seeking to meet 100 per cent of Games time demand from new, London-based, renewable sources and 100 per cent of legacy demand from on-site renewables.
“Any Games time to legacy surplus should be fed back into the grid. Only then will the 2012 Olympics start to live up to its claim to be the greenest games, providing a more sustainable legacy for London.'
The Olympic Delivery Authority claims the centre will be flexible enough to include future technologies.
Peter Smith, research and communication manager at the Combined Heat and Power Association, said: “We are happy with the level of ambition the ODA has shown so far and they recognise CHP is the most appropriate for the urban density they are planning. If future targets change we will continue to press that our technology can help achieve them.”
