Aspiravi and Spano build 26MWe biomass power plant in Belgium - advanced circulating fluidized-bed
Renewable energy company Aspiravi NV and wood products manufacturer Spano NV have formed A&S Energie, a partnership that will begin to build a 26MWe biomass power plant in Oostrozebeke, Belgium, next month. Foster Wheeler's Finnish subsidiary Foster Wheeler Energia Oy has been awarded the contract by Prokon Nord Energiesysteme GmbH - which will engineer and construct the plant - for the advanced circulating fluidized-bed (CFB) steam generator that will form the core of the power system.
The €90 million (US$141m) project will be located near the Roeselare-Leie canal which will make it easy to efficiently transport the estimated 170,000 tons of uncrecyclable wood waste that will be used as fuel each year.
The facility's net production will be 175GWh of green electricity per year, enough to meet the needs of 50,000 families. Part of the electricity will be utilized by Spano, but the bulk produced will be sold to the local grid.
The decision by the companies to build a medium-scale green energy plant is seen as courageous, given the fact that Belgium's energy market is not as free as some would want it to be. The market is basically controlled by the monopoly of giant Electrabel, the formerly state-owned utility, which sells electricity generated by nuclear power plants it acquired virtually for free after it was privatized.
The new power plant's fuel will be burned in a highly efficient and advanced circulating fluidized-bed (CBF) that allows for clean combustion. Spano NV, a large manufacturer of wood products, will be responsible for the supply of non-recyclable wood residue to be used as fuel. The fuel will be obtained after meeting the requirements of 'Lansink's ladder', a set of hierarchically ordered steps formally used to determine waste management options. The wood waste goes through a cascade of recycling possibilities, and only that fraction that can no longer be re-used will become feedstock for energy. Highly efficient energy production is preferred over landfill:
energy :: sustainability :: biomass :: bioenergy :: wood :: waste :: circulating fluidized-bed :: renewables :: Belgium ::
The biomass power plant makes Spano NV an entirely carbon-neutral company. For Aspiravi NV the facility means an important diversification of its renewable energy portfolio, which currently consists of 22 combined heat and power (CHP) projects, 4 biogas facilities, 55 wind turbines and 2 hydropower plants.
For Foster Wheeler, the contract means the confirmation of its strength in engineering advanced boilers. This will be the fourth CFB steam generator the company has provided to Prokon Nord in the past five years. Foster Wheeler CFBs are currently operating in Prokon Nord projects in the German cities of Papenburg, Hamburg and Emlichheim. Prokon Nord is a leading German renewables engineering company with a large portfolio of biomass CHP, wind and geothermal projects.
With a share of 55%, biomass is the most widely used form of renewable energy in Belgium. The country has an obligation to meet its renewable energy targets set out by the EU: 6% of all electricity and heat should come from renewables by 2010. Even though this puts Belgium in the group of countries with a low target, the country needs to invest more into the sector, which currently only has a share of 2.5% in the energy portfolio.

Austin Energy plans $2.3 billion investment in biomass power
Austin Energy spokesman Ed Clark said power from the biomass plant would move the city closer to its goal of getting 30 percent of its power from renewable sources by 2020. Nacogdoches Power LLC would build and run the plant and Austin would buy all the power. The price tag would include the cost of fuel and operating expenses.
The 100 MW wood-fired biomass electric generating facility consist of a wood fuel handling feed system, a wood-fired system generator, a condensing steam turbine generator with an evaporative cooling tower and auxiliary support equipment. The project will employ the latest in boiler and emissions control technology to achieve the best available emissions.
The biomass fuel will be comprised of forest residues, whole tree chips, municipal tree waste and mill residue.
The steam generator will be a bubbling fluidized bed boiler. The boiler will be equipped with a baghouse to control particulate emissions. A Selective Non-Catalytic Reduction (“SNCR”) system will be provided for NOX control.
The project will be unique among renewable energy projects in that it will have an extremely high availability factor (approximately 90%) and will be capable of operation as a base load generating resource:
energy :: sustainability :: biomass :: bioenergy :: biofuels :: wood :: waste :: renewables :: Texas ::
Further, the project will qualify for renewable energy credits, (RECs) under current Texas law and Public Utility Commission rules. The project will help Texas meet the legislatively established requirement of 500 MW of new non-wind renewable generation and the overall goal of 5,880 MW of renewable generation by 2015 under Texas Senate Bill 20, enacted in July 2005.
In addition to using state of the art emission controls, the power plant will offer other significant environmental benefits. The project will use logging residue as a wood fuel source, improving sustainable forest management practices and reducing the impact of greenhouse gases created by the decomposition of logging residue.
The project is located in the town of Sacul, Texas. The proposed site is a 130 acre parcel which is situated in the northwestern portion of Nacogdoches County. The area is rural with a low population density. The site is partially cleared with mature trees on the portion of the property to be developed for the Project. The site has adequate space for the footprint of the power generation facility, fuel delivery and handling as well as for construction.
Biomass is gaining a foothold in Texas. The Electric Reliability Council of Texas, which operates most of the electric grid in the state, draws power from 37 generating plants producing 97 megawatts of power from biomass. Most of those plants are powered by landfill gas, and the rest draw from agricultural byproducts, like the proposed Nacogdoches Power plant. A 45-megawatt plant, running on agricultural byproducts is expected to come online in Lufkin next year, but the Austin Energy partnership will be the largest planned biomass plant in the ERCOT area.
Austin Energy serves 388,000 customers in Austin, Travis County and part of Williamson County. It owns 2,600 megawatts of generation from three natural gas-fired plants near Austin and owns shares of a coal plant in La Grange, a nuclear reactor in Bay City, and wind farms in West Texas.
Nacogdoches Power is a joint venture between Bay Corp Holdings, Ltd and Energy Management, Inc. BayCorp, is a privately held energy company that has been in existence for 20 years. Until November 1, 2002, BayCorp owned a 15% (174 MW) joint ownership interest in the Seabrook Nuclear Power Project in Seabrook, New Hampshire through its two principal operating subsidiaries, (Great Bay) Power Corporation (“Great Bay”) and (Little Bay).
EMI is a privately held energy company with more than 30 years of experience in energy conservation and energy development. In 1975, EMI began developing energy conservation and pollution control projects for institutional and industrial facilities. A decade later, the company transitioned to developing independent power projects. In 1986, EMI developed, financed and constructed Alexandria Power Associates, a 15 MW wood-fired power production facility in Alexandria, New Hampshire. Following Alexandria, EMI developed six natural gas-fired electric generation projects totaling more than 860 MW of capacity and including the first true independent and merchant power projects in New England. At one point, facilities developed by EMI represented $800 million in construction and 8% of New England’s base load capacity.
In 2000, EMI’s principals sold their interests in its portfolio of natural gas-fired facilities and changed their focus to developing renewable energy projects. EMI is also currently developing the Cape Wind Project, a 468 MW offshore wind project to be located in Nantucket Sound off the southern coast of Cape Cod, Massachusetts.
