The London King’s Cross district cooling system is now fully operational


A new district cooling network will


serve an area in London north of Regent’s Canal, providing carbon-efficient cooling to four commercial and three residential buildings. It has been designed to enable later expansion to further buildings and customers. The new cooling network operates alongside Metropolitan’s district heat network which has been providing heat and power for King’s Cross since 2013. At the heart of Metropolitan Infrastruc-


ture’s new network is the ‘cooling pod’; housing six chillers, it will generate 9MW of cooling to the development north of Regent’s Canal. The network will serve four commercial and three residential buildings, and has been designed to allow expansion at a later date. The cooling pod is part of the utility


infrastructure at King’s Cross delivered by Metropolitan, which includes district heating, electricity, ultrafast fibre broad- band, gas, water, and wastewater. Cooling capacity, determined by the


available energy generated by the energy centre, is 12.5MW, with an effective 9MW available – 6.5MW of which will be used for commercial cooling and 2.5MW for residential.


Cooling pod specification 1 x 1.4MW absorption chiller 3 x 3MW water-cooled electric chillers 2 x 1MW dry air-cooled chillers 5 x 2.5MW heat-rejection cooling towers 2 x 30m3 thermal stores 2 x 2,500kVA transformers


2.66GW Mekong Dam a ‘disaster’ for VietNam


A plan for Cambodia to build the Mekong River’s biggest dam would destroy fisheries which feed millions and worsen tensions with Vietnam, the downstream country with most to lose from dams on the waterway, according to a three-year study commissioned by the Cambodian government. The report says the 2.66GW Sambor dam would “generate large power benefits to Cambodia, but at the probable cost of the destruction of the Mekong fishery, and the certain enmity of Vietnam.” It said the dam designed by China Southern


Power Grid Co. would have a 620-square- kilometre (239-square-mile) reservoir and dwarf the biggest dam currently being built on the Mekong, the Xayaburi dam in Laos, which was bitterly opposed by environmen- talists for years. The experts at the Natural Heritage Institute who authored the report, submitted to the Cambodian government late last year, recommended it defer the project while studying ‘better’ alternatives such as using solar power to augment existing hydroelectric dams.

Dalkia acquires majority stake in TIRU Dalkia, a 100% owned subsidiary of


The system uses three different types of chillers – absorption, water-cooled and air-cooled – together with a key Building Management System. John Marsh, Managing Director of


Metropolitan Infrastructure, says that the district cooling network will have real benefits for customers: “The advantages extend beyond the expected reduction in running costs and capital savings. Customers of the district heating network are protected by the scheme’s membership of the Heat Trust, a self- regulatory initiative which recognises best practice, and we are confident that district cooling systems will also be covered under the scheme in the near future.”


the EDF group, recently acquired a 75% stake in TIRU, a company spe- cialising in recovering energy and materials from household waste, providing electricity and steam for district heating networks and industrial sites.


Established in 1922, TIRU


(Traitement Industriel des Résidus Urbains) designs, builds and operates waste treatment facilities in France, the UK and Canada. TIRU is a long- standing operator for the French metropolitan household waste agency (Syctom). The company specialises in heat recovery (burning household waste to produce electricity and steam), biological recovery (breaking down organic matter to produce compost and biogas) and materials recovery (sorting and treating recycled waste).


Fortum to install the


largest rooftop solar power system in


Nordic region Fortum has won a key contract to install the largest rooftop solar power system in the Nordic region. Fortum and S Group say they have come to a mutually beneficial agreement on the installation of the largest rooftop solar power technology. The majority state-owned energy company revealed this morning that it submitted the winning bid for implementing the electricity system on the rooftops of approximately 40 commercial buildings owned by S Group, a Finnish retail co-operative, across Finland. With a total capacity of roughly 10 megawatts, the system would have accounted for nearly a third of the total solar power capacity of Finland in 2017 and will become the largest rooftop solar power system ever inaugurated in the Nordics. S Group, meanwhile, stated that its objective is to use its renewable energy assets to generate 80% of the energy it consumes .
