Council's ambitious plans to run energy firm secures £58m backing

AN ENERGY company set up to fight climate change and ’revolutionise’ north London’s energy future has been given £58m by Enfield Council.

The council has created its own energy firm to supply heat and water to more than 15,000 homes and businesses in the next four years.

Last week it backed the £85m business plan for the new company – energetik - to develop, and run, four energy networks to supply low carbon heat and hot water.

The council says energetik’s customers will be charged a fair price and get better customer service than a private-sector energy company provides.

Enfield’s £58m will be supplemented by the company’s own income, with energetik’s business operations bringing the total up to £85m over the next 40 years.

Enfield Council’s cabinet member for economic regeneration and business, Cllr Alan Sitkin, said: “Energetik is a ground-breaking venture which will return £225m of economic, environmental and social benefits to residents and businesses.”

That figure is an estimate, over 40 years, of the benefits of cleaner air, fewer carbon emissions and the impact of potential investment the council hopes to reap.

A report on setting up the company says benefits include “delivering a council-owned heat company to underpin the council’s regeneration ambitions; the ability to provide cleaner air; and the benefits of providing state of the art smart metering to customers.”

Energy centres at Meridian Water, Arnos Grove, Ponders End and Oakwood will supply the heat and hot water through a network of insulated pipes. The networks can use waste heat and will be able to adopt future heat technologies.

Jayne Clare, energetik’s managing director said “energetik is using Scandinavian design standards to improve the service and the industry in an unregulated market. We are putting customers’ needs first, before rates of return. We want to revolutionise the local energy market and be the supplier to trust.”

Of the council cash, £12m has come from the European Investment Bank and the London energy efficiency fund.

The first 40 customers, at the Montmorency heat network, are planned to receive heat in early 2017.

Star's ammonia district heating and cooling system wins ASHRAE Award

Dr Andy Pearson, group managing director of Star Refrigeration and Azane Inc., has won an award for designing the world’s largest ammonia heat pump.

Star Refrigeration’s Dr. Pearson, the lead engineer behind the biggest ammonia heat pump for any district heating and cooling scheme, won the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) prestigious ‘Comfort Cooling Award for Project Excellence’ at the Society’s Winter Meeting in Las Vegas on 28 January.

The high-temperature district heating and cooling system uses a water-source 13 MW heat pump to deliver cooling and heating to businesses, schools, hospitals and buildings in the coastal town of Drammen in Norway.

The town of 65,000 inhabitants also receives hot water pumped directly into the mains by the heat pump. The system works by extracting warmth from the cold waters of a local river and then heating it to 900oC for heating.

Dr. Pearson oversaw the first ammonia project, at Star Refrigeration headquarters in Glasgow, to use the natural refrigerant in such a large high temperature district-heating scheme.

Norwegian energy supplier Drammen Fjernvarme AS, who operates the project, reports that the heat pump has served 85% of the city’s heat demand and delivered over 400 GWh of clean heat since its installation in 2011.

The electricity consumed by the heat pump mainly comes from hydropower, reducing the system’s carbon footprint to virtually zero, according to Star Refrigeration.

Jon Ivar Bakk, CEO of Drammen Fjernvarme AS, said, “the system has been working uninterrupted for over five years and has delivered savings of €10m and 75,000 tonnes of carbon emissions to date. Our system’s technology offers a reliable and sustainable source of clean energy to meet the town’s heating needs.”

““I am honoured to accept this award from my fellow members of ASHRAE on behalf of all of the team at Star Refrigeration”, said Dr. Dave Pearson, Star Refrigeration's managing director.

Collecting the award, Pearson said, “I am honoured to accept this award from my fellow members of ASHRAE on behalf of all of the team at Star Refrigeration who worked hard to deliver Drammen’s vision of a community-wide, carbon free heating system”.

“The award not only credits innovation but offers an insight to the considerable scope for the environmental and economic benefits that district heating and cooling systems can offer to entire communities,” he said.

District Heating Heats Up in the U.K.

District heating is a hot item in the United Kingdom. Earlier this month, the Building Engineering Services Association (BESA) said that it will create the UK’s first test standard for heat interface units (HIUs).

HIUs are the devices that divert heat from the network into structures. This is an obviously critical element that, according to the story in Heating and Ventilation, often fails to perform adequately in U.K. district heat networks.

The test methodology was adopted from a Swedish method under funding from the Department of Energy and Climate Change (DECC).

District heading also is seen as a key tool elsewhere in the U.K. On January 24, the Scottish government released a draft climate change plan. The government aims to produce 80 percent of residential heating from low carbon sources. Scottish law firm Brodies LLP points out that low carbon is not synonymous with renewable and commercial and industrial use are not included. It calls the target “transformative” nonetheless.

The analysis at Lexography says that district heating is one of the strategies that will be used. Scotland plans to regulate district heat. The piece points out Scotland will do so before England, which also has plans to regulate. Usually, the commentary says, England leads and Scotland tweaks and adopts.

Decentralized Energy this week that the U.K.’s Chief Energy Advisor at the Danish Embassy said that the British district energy business is booming. Ian Manders said that the value of the market has risen from £76 million to £350 million in just one year.

The newest member of the district heating club in the U.K. is IKEA. Last week, the company said that its new store in Sheffield will include district heating.

BESA publishes district heating standard for HIUs

A new standard which will tackle the "Achilles heel" of district heating networks and improve the overall efficiency of schemes is to be published by the Building Engineering Services Association (BESA).

The standard will be used to compare manufacturers' products and equipment types to help network designers evaluate performance against their design parameters.

It will also be used to create a comprehensive database and improve the industry's knowledge of heat interface unit (HIU) performance to inform future network design.

The performance of HIUs, which are used to extract heat from the network to feed individual buildings, is critical to occupant satisfaction levels and the overall efficiency of the schemes in terms of return temperatures and network sizing.

HIU are often the reason for networks failing to meet their efficiency targets. BESA said HIUs have proven to be an "Achilles' heel" of district heating networks.

BESA's technical director Tim Rook said: "This standard is, therefore, a major step forward for UK heat networks and it is a real accolade for BESA to be asked to publish and disseminate it on behalf of the industry."

The standard is being adopted from a test regime initially developed by energy consultancy FairHeat which was adapted form a well-stablished Swedish methodology to suit typical UK operating conditions as part of a research project funded by the Department of Energy and Climate Change.

FairHeat managing director Gareth Jones said: "BESA is very well respected in the sector and we are delighted they have decided to take our regime and publish it as a standard.

"It is amazing to see how far the regime has come from a research project, developed with grant funding, to a recognised standard that will be used across the sector to improve heat network efficiency."

Geothermal district heating could become reality in Stoke-on-Trent by 2019

If progressing as planned, district heating fuelled by geothermal energy could become a reality for the first residents in Stoke-on-Trent in the UK, in a project by the municipality and private company GT Energy.

A joint project by the city of Stoke-on-Trent in the UK, and private developer GT Energy continuing development of a geothermal district heating network.

As part of the project – so local news – about 1,000 people could benefit from the heating scheme in the early stage as early as 2019.

The GBP 52 million ($64 million) project would connect high-density housing the municipality with geothermal heating. With the project customers are expected to become independent from price fluctuation sin fossil fuels, while reducing carbon emissions.

Around GBP 20 million have been secured from the government through a City Deal, with private company GT Energy to invest additional millions of pounds into the the geothermal plant.

The city council secured GBP 19.75 million (USD 24 million) from the Government for the DHN project through its City Deal.

The local community welcomes the project, as currently around third of the people’s income goes into paying for heating during the colder time of the year.
