A demand response technology company in the UK has said that London’s planned construction of new decentralized energy capacity is ‘a poor use of money’.
Lucy Symons, policy manager at demand response firm Open Energi, said this week in a post on the company’s website that the Greater London Authority’s planned construction of 119 MW of new cogeneration plants, which aims to meet 25% of the city’s power and heat needs by 2025, will be costly to build, vulnerable to volatile global gas prices, carbon-emitting, and require more space than the city can afford.
In addition, she said the GLA’s plan to place small wind turbines at sites around the city, to be realized by 2050, ‘depend[s] on technological developments’.
Instead, Symons said, London should examine demand-side energy management. She said that, according to Open Energi’s model of the city’s industrial and commercial energy use (pictured), ‘a whole gigawatt of “spare” capacity’ is available - currently used to power businesses and residences between 4pm and 7pm.
‘Shifting 1 GW out of the peak would save the need to build a new mega power plant, equivalent to the size of [the 1 GW gas-fired] Barking power station,’ Symons said.
