Wärtsilä to supply flexible 100MW combined heat and power plant to Germany

Finnish energy equipment manufacturer Wärtsilä will supply a 100MW combined heat and power (CHP) plant to Germany-based energy producer Kraftwerke Mainz-Wiesbaden. The Smart Power Generation power plant, consisting of ten Wärtsilä 34SG engines running on natural gas, is scheduled to be fully operational by the end of 2018.

Wärtsilä's scope covers the engineering, procurement and construction (EPC), as well as a 15-year service agreement with performance guarantees. The order is included in the order book for the fourth quarter, 2016.

"Unlike traditional CHP power plants based on coal fired units or gas turbines, the Wärtsilä gas engines can be started and stopped without limitations within just 2 minutes. This allows us to operate in the balancing markets, since we can adjust the power output quickly to respond to the fluctuations in power demand as signalled by the electricity price," said Lars Eigenmann, CEO at Kraftwerke Mainz-Wiesbaden AG.

UK government aims for clearer vision for heat decarbonisation

The UK energy minister says her department hopes to provide a clearer vision to its strategy for heat decarbonisation in 2017, as she announced changes to the main policy driving that agenda, the Renewable Heat Incentive.

Baroness Lucy Neville-Rolfe, Minister of State for Energy and Intellectual Property acknowledged that the country had yet to fully agree on the optimal mix of technologies required to decarbonise the heat sector in the most cost effective manner.

She was speaking at the Heat Summit event which also heard from the authors of recent reports by hosts Policy Exchange, Imperial College, and KPMG/ Energy Networks Association.

The minister referred to the technologies currently available, without outright commitment to any one method.

“Heat is very difficult to decarbonise and no consensus is yet reached on the mix needed for the long term and you will have seen that from the various different reports on the subject.”

“We need to be clear on the challenges, clear on the things we start to make progress on now and we need to agree on a long term direction.”

“It is significant that over the last few decades there has been an accumulation of evidence on climate change and a growing momentum in the need to tackle it urgently, leading to the landmark of Paris and ratification by the UK. It is an important sign of our commitment to tackle climate change both here and the rest of the world.”

Two new directors at Sweco as firm eyes growth plans

ukDEA member Sweco has appointed two new members to its UK leadership team to head up its environment and energy business units as the company prepares for further growth.

The Leeds-headquartered engineering, environment and design consultancy has appointed Jen Hamilton to lead its environment unit, whilst Andy King will take of the energy unit. Both are directors and have been with the consultancy for 10 and five years respectively.

Sweco now has five distinct business units comprising buildings, environment, energy, transportation and water and asset management, and these latest appointments ensure each unit is represented at board level.

The promotions also mark a period of successful integration since Sweco launched in the UK in April 2016, following its acquisition of Grontmij in October 2015. Among the work it has been involved in includes the delivery of a district heating network connecting 53 buildings within the University of Glasgow estate to a new energy centre.

Together, the consultancy’s energy and environment teams are part of a consortium implementing Nemo Link, an electrical interconnector between the UK and Belgium. They are also providing design and environmental planning consultancy services for several energy schemes and have a market-leading position in on-shore wind. Sweco’s UK managing director, Max Joy, said:

“Our integration continues to progress at an excellent rate and we are very well placed to become even more successful.

“These additional leadership team appointments ensure our core businesses are aligned with market sectors in a way that creates many advantages for both our company and our clients. Importantly, the structure also enables pan-business representation on the leadership team giving further impetus to our collaborative multi-disciplinary approach.

“We’re very pleased to introduce Jen and Andy onto the leadership team. They are both highly capable individuals and great leaders, who have proven themselves to be assets to our business. We look forward to them helping deliver our controlled strategic growth plan.”

The consultancy employs 800 people in the UK and advises on major projects. Sweco has its headquarters in the Chapel Allerton area of Leeds and consults nationwide via its network of offices in Bristol, Cardiff, Edinburgh, Glasgow, London, Maidenhead, Manchester, Newcastle, Peterborough and Solihull.

New public sector energy company announced for Devon

A pioneering new energy company, designed to deliver more efficient heat and power in Devon, has been announced

The innovative company, called Dextco, will develop ground-breaking sustainable projects to provide environmentally-friendly energy to homes and businesses across the city and its surrounding area.

The company - whose founder members and shareholders comprise of The Royal Devon and Exeter NHS Foundation Trust (RD&E), the University of Exeter, Devon County Council, Exeter City Council and Teignbridge District Council - is the first specifically Exeter-based energy company in almost 70 years.

Building on recent success of Cranbrook and Skypark's award winning district heating scheme, plans are already in place to undertake the first project associated with the new company in Exeter. A revolutionary new network will be financed and built, designed to transport heat generated at the RD&E's Wonford Hospital to consumers across the city. Feasibility studies for the project, which would increase energy efficiency and reduce costs, have identified that the scheme is achievable.

Denmark's largest power station replaces coal with wood pellets

​Avedøre Power Station can now use sustainable wood pellets as fuel instead of coal.

For the past 18 months, Avedøre Power Station has been converting its coal-fired power station unit, and the entire combined-heat-and-power (CHP) plant is now able to produce electricity and heat based on wood pellets and straw, rather than coal and gas.

"Following the conversion of unit 1 at Avedøre Power Station, we can produce heat for more than 215,000 Danish households in the Greater Copenhagen area without using coal or gas. The conversion is a major contribution to achieving a green district heating system in the Greater Copenhagen area as well as a green electricity system, supplementing solar and wind power," says Thomas Dalsgaard, executive vice president at DONG Energy.

The conversion—part of a heat agreement between the Danish energy companies 'Vestegnens Kraftvarmeselskab' (VEKS) and DONG Energy—aims to provide green district heating to VEKS' customers in the Greater Copenhagen area. The change from coal to sustainable wood pellets also contributes significantly to the city's climate targets. Avedøre Power Station expects to reduce its CO2 emissions by about 500,000 metric tons CO2 per year, equivalent to the annual emissions from 255,000 cars.

"Choosing the right levers to curb the ongoing CO2 emissions and thereby global warming is a complex task. However, using biomass at Avedøre Power Station's two units is a huge step towards achieving VEKS' goal of supplying fossil fuel-free district heating in 2025. We’ve made a difference," says Steen Christiansen, chairman of VEKS.

DONG Energy has reduced its coal consumption by 74 percent since 2006 by using more wind and biomass, and the trend is continuing. Studstrup Power Station, near Aarhus, made the transition from coal in October, and now it's Avedøre Power Station's turn.

"We’re reducing our annual coal consumption at Avedøre Power Station by around 160,000 metric tons. This is very good for the climate and in line with the conversion of our power stations, which has been ongoing for several years," Dalsgaard says.

Avedøre Power Station is expected to produce district heating based on biomass to approximately 215,000 Danish homes in Copenhagen as well as electricity corresponding to the annual consumption of more than 600,000 Danish households annually.
