HEAT & POWER Bioenergy Internat ional No 79, 3-2015 47 DONG to convert final Avedøre unit Danish energy major DONG Energy has announced that it will go ahead and convert the last combined heat and power (CHP) unit, Unit 1, at its Avedøre Power Station to run on wood pellets instead of coal. The conversion enables green heat for an additional 65 000 households in the Greater Copenhagen area. DONG estimates that the largest CHP plant in Denmark will be able to supply heat and power based entirely on pellets and straw instead of coal and gas by Q3 2016. DONG Energy has also signed a new off-take agreement with the district heating distribution company VEKS. The deal means that from 2016 until 2033, Unit 1 at Avedøre Power Station will be able to supply green heat to VEKS’ customers. The agreement forms the basis of the investment, which is being financed by both companies, to convert and prolong the lifetime of the CHP unit. Once converted, Avedøre Power Station expects to be able to produce district heating based on biomass for approximately 215 000 Copenhagen households as well as electricity corresponding to the annual consumption of more than 600 000 households. Avedøre Power Station has two units. Unit 1 is now being converted and is expected to use wood pellets as primary fuel, but it will still be possible to use coal as fuel. Unit 2, featured in Bioenergy International no. 5/2014, is a multi-fuel plant consisting of a main boiler, which uses wood pellets as fuel, a straw-fired boiler and two gas turbines. – The decision to convert Unit 1 at Avedøre Power Station means that we’ll now be in a position to abandon coal and gas entirely when we’re generating heat. It’s a significant step in the green conversion, taken in a cost-effective way, said Thomas Dalsgaard, Executive Vice President, DONG Energy in a statement.

Tentatively named Nippon Paper Ishinomaki Energy Center Ltd the new company is to build a new 149 MWe plant on the Hibarino site owned by Nippon Paper Ishinomaki Mill. The operation and maintenance of the power generation facility will be contracted to Nippon Paper Industries, and electricity will be sold to a Power Producer and Supplier (PPS: Specified Scale Electricity Utility). The plant will use up to 30 percent biomass and is expected to commence operations in March 2018. According to the statement the project is in line with Nippon Paper Industries’ goal to transform its current business structure into a comprehensive global biomass business. BI79/4867/AS UPM Plywood, a subsidiary of Finnish forest products major UPM, has announced that it is to invest around EUR 40 million in expanding the capacity of its Otepää plywood mill in Estonia. In addition to the mill expansion, the investment also includes a new 18 MW biomass heat boiler to replace the old, partly oil-burning plant. The expansion includes a new plywood production line with all machinery needed for veneer and plywood manufacturing. Around 8 000 m2 new production premises will be made by connecting existing buildings together. Scheduled to be completed by the end of 2016 it will almost double the production output to 90 000 m3 per annum and create 40 new jobs. – The expansion of Otepää mill increases our capability to deliver competitive birch plywood and improves the mill’s material, resource and operational efficiency. New competitive production capacity improves our capability to respond to growing demand and to serve our key customer industries more reliably and effectively. The environmental performance of the mill will also improve since the new biomass plant will generate all heat energy for the mill, said Mika Sillanpää, Execut ive Vice President of UPM Plywood in a statement. Currently the largest plywood mill in Estonia, the Otepää plant produces 50 000 m3 per annum coated and uncoated birch plywood used for construction, vehicle f looring and LNG carriers. BI79/4851/AS Finnish energy major Fortum has revealed plans to build a new multi-fuel combined heat and power (CHP) plant in Zabrze, Poland. To be primarily fuelled by refuse-derived fuel (RDF) and coal it will also be able to use biomass and a mixture of fuels. The new 220 MW plant will replace the existing purely coal-fired, outdated units in Zabrze and Bytom. The total value of the invest- ment is approximately EUR 200 million (PLN 870 million) and it is estimated to start commercial operations by the end of 2018. Construction is expected to begin later this year, subject to the local environmental impact assessment process and other negotiations. The plant will have a production capacity of 145 MW heat and 75 MW electric and the amount of RDF can be up to 50 percent of the total fuel usage. The residential and industrial waste for RDF is to be sourced locally. – Efficient combined heat and power production is one of Fortum’s three strategic core competences. With our experience in efficient energy production and focus on tackling climate change, we want to contribute to the ongoing transformation of the Polish energy sector. Poland is one of the biggest district heating markets in Europe, and we are well established there, said Markus Rauramo, Executive Vice President, Heat, Electricity Sales and Solutions division at Fortum. Fortum has been operating in Poland since 2003 and currently has four CHP units and over 800 km of district heating network, which serve in total 360 000 households in the cities of Płock, Wrocław, Częstochowa, Zabrze and Bytom. The total power generation capacity is currently over 200 MW and heat generation capacity is over 1.1 GW.
