INTRODUCTION
1.1 BASIS Abstract
BASIS aims at interacting with bioenergy project developers and investors, providing them a
comprehensive view on supply risks by combining information on biomass demand and biomass potential.
In fact the core idea of this project is to provide in-depth information on the situation of wood chips demand
by combining the actual consumption data based on the identification of bioenergy plants (above 1 MW) using
wood chips and other wood chips consumers in the same region with the estimated potential and sustainability
criteria. This information collected will be condensed in a comprehensive and easy to use Geographic
Information Systems tool. http://www.basisbioenergy.eu/
Why wood for wood chips boilers?
BASIS addresses wood supply for wood chips boilers for two main reasons: 1.wood chips are by
far the main form of wood used for medium and large scale projects and 2. wood chips are
mainly traded on a local and regional basis
As a result BASIS will strongly increase market transparency in the wood chips markets:




Investors would be able to use BASIS for the risk assessment of projects in pre-development stage to
assess whether a region has enough feedstock potential for a sustainable supply of wood chips over
the investment period.
Feedstock suppliers will use it to find new customers and develop their biomass supply.
National and regional policy makers as well as the EU Commission are provided with a comprehensive
overview of biomass use in plants above 1 MW capacity, bioenergy conversion efficiency as well as a
detailed insight on sustainability aspects from a market perspective.
Project developers would be able to use BASIS in combination with the results of Cross Border
Bioenergy (http://www.crossborderbioenergy.eu/) to find attractive locations for new projects.
1.2 Conversion efficiency of biomass
All along BASIS project special attention has been paid to plants efficiency, mainly due the growing concerns
around the efficient use of biomass. In this context, a dedicated data collection was done aiming at aggregating
updated and relevant figures directly obtained from plants using woodchips. However presented figures could
only provide a general insight, they could not be understood as national referent or comparable values. This is
mostly for two major reasons: 1° the definition used to define efficiency and 2° the number of plants presented
per country as explained in the following section.
1.2.1 What is the efficiency of a plant using woodchip as fuel?
Energy efficiency has become a generic term which hides various realities and calculation methodologies that
can slightly differ from one study to another. In general, efficiency commonly refers to a percentage
corresponding to the ratio between input of energy content of woodchip and heat/electricity energy output as
follow:
4
𝐸𝑓𝑓𝑖𝑒𝑛𝑐𝑦 =
𝐹𝑖𝑛𝑎𝑙 𝑒𝑛𝑒𝑟𝑔𝑦 𝑖𝑛 𝑡ℎ𝑒 𝑓𝑜𝑟𝑚 𝑜𝑓 ℎ𝑒𝑎𝑡 𝑜𝑟 𝑒𝑙𝑒𝑐𝑡𝑟𝑖𝑐𝑖𝑡𝑦
𝑊𝑜𝑜𝑑 𝑐ℎ𝑖𝑝 𝐹𝑢𝑒𝑙 𝐼𝑛𝑝𝑢𝑡 (𝐿𝐻𝑉)
This calculation is used mostly to obtain the potential efficiency of boilers units. However, in practice boiler
efficiency is directly affected by a wide range of both internal and external factors (e.g. climate, scale, moisture
content in biomass etc)1 and can also be optimized among time (using the produced heat; application of addon’s to increase electricity or heat production; technological improvements of the combustion technology;
increasing plant capacity).
Moreover, if boilers are central elements within bioenergy plants, the global efficiency of these plants are also
affected by the efficiency of side components and the network in which they are integrated, as presented
below in the case of heat and CHP plants.

In this context, evaluating the effective efficiency of a whole biomass plant using woodchips could result in
extensive calculations. This was not the purpose of BASIS which rather focus on the development and
implementation of a common methodology to collect harmonized data for all EU countries. Moreover
collecting the efficiency for each bioenergy plant in Europe would be extremely complicated, not only because
of difficulties in measuring/calculating it, but also for confidentiality reasons regarding its sensitivity for plant
owners.
Consequently, in order to have a single and simple way to obtain the yearly efficiency figure for a plant, BASIS
consortium agreed on the following methodology.
In this report, biomass plant has been considered as a “black box”, no distinction have been made between
boiler efficiency and efficiency of other plant’s components. Plant efficiency could be then calculated as a
single ratio between the annual woodchip input expressed in MW and the annual heat/electric output also
expressed in Megawatt as follow:
1
“Evaluation of improvements in end-conversion efficiency for bioenergy production”, ECOFYS, 2009.

𝑃𝑙𝑎𝑛𝑡 𝐸𝑓𝑓𝑖𝑒𝑛𝑐𝑦 =
𝐹𝑖𝑛𝑎𝑙 𝑒𝑛𝑒𝑟𝑔𝑦 𝑖𝑛 𝑡ℎ𝑒 𝑓𝑜𝑟𝑚 𝑜𝑓 ℎ𝑒𝑎𝑡/𝑒𝑙𝑒𝑐𝑡𝑟𝑖𝑐𝑖𝑡𝑦 (𝑖𝑛 𝑀𝑊ℎ)
𝑊𝑜𝑜𝑑 𝑐ℎ𝑖𝑝 𝐹𝑢𝑒𝑙 𝐼𝑛𝑝𝑢𝑡 (𝑖𝑛 𝑀𝑊ℎ)
This simple methodology presents some advantages: 1° it could be applied uniformly and simply in the
different countries participating in the data collection 2° it could allowed to establish comparison between
countries and plants types 3°it could also be applied for the calculation CHP plant efficiency what allows to
present separated figures for both heat and electric efficiency.
1.2.2 Conversion efficiency of biomass - data collection methodology
The objective fixed was to obtain efficiency figures for 3 plants per type and size as presented in the template
model bellow. For each plant, the operating date has also been requested in order to use these information
afterwards to evaluate plant efficiency evolution (graph 3.1.2 General overview) among time.
Due to Heat, Electricity and CHP plants specificities, some additional information have been added within
efficiency figures data collection:
-
For CHP plants, combining heat and power, both electric and heat efficiency figures have been
requested separately.
-
For Heat plants, information around plant type have been deepened by asking if heat plants are
Industrial, residential or district heating systems.
-
For Electric plants, after having collected European data on the issue, it has been noticed that very
few Electric plants had an annual production under 5MW mostly because of profitability reasons. Then
it has been decided to collect efficiency figure for plants between 5-15 MW / 15-25 MW and for plant
bigger than 25 MW in that special case.

Figures presented in the table above are resulting from the aggregation of data contained in national templates. As previously explained these efficiency values could not
be understood as national referent values due to the specific methodology used in this study (1.2.1). Moreover energy efficiency values presented here, especially in the
case of CHP plants, should also be reconsidered in the context of 2013 and its specific climate conditions. Because of a fairly mild winter, CHP plants could have strategically
adapted the E/H production ratio, consequently the energy efficiency would have been impacted.
However some general conclusions could be extracted from this table. The figures above show very homogenous values per plant type for CHP and heat installations. In
fact, in 2013 the global efficiency of CHP in European countries was around 86 % (heat + electric efficiency) whereas heat plants efficiency reach 80 %.
One major BASIS outcome has been to highlight the limited number of electric Plant currently producing power from wood chip in EU-28 (less than 1% of the total of
bioenergy plants). In this context, few data could be collected for electric plant efficiency at national level as reported in the template. Then trend for 2013 seems less easy
to estimate even if data were closed to 30%.

This increasing tendency could mainly be explained by the implementation of
technical progress that have allowed a great part of recent CHP plants to
reach an average electrical efficiency over 20 % and a thermal efficiency over
60% and state supports that have encourage national operators to optimize
their installations.

Comparable trend has been noticed for heat plants regarding their date of
commissioning. This could also be explained by the funding policy in BASIS
partners’ countries. Through a permanent tightening of the funding
conditions, the efficiency of the plants is constantly being improved. Due to
technical progress efficiency level over 85 percent are now possible.

In Austria the efficiency of CHP and biomass heating plants is similar to the efficiency in other European countries. From an
economic perspective, the plant operators are interested in optimizing their systems. In Austria there is a wide pallet of
funding opportunities to increase efficiency. Legal and economic framework conditions are ideal for an increase of efficiency.
CHP plants have an electrical efficiency in the range of 20 percent. The thermal efficiency is generally above 60 percent and
9
increases with system size. For biomass heating plants, the efficiency is around 80 percent. Larger plants have made a better
efficiency. In Austria there are only 2 biomass heating plants over 20 MW. Therefore a general statement about the efficiency
over 20 MW can not be done.

Due to legislation, in Spain the electric plants projects are stopped since a couple of years because the feed in tariffs have
changed and now they are quite low. The plant Es-41-2 is one of the lastest projects to be finished that’s one of the reasons
why the efficiency is higher. Also it’s higher because usually, the biggest the plants are in size, the better is the efficiency.
The majority of the plants of Region 61 were made several years ago (5-10 years) to burn olive cake due to the huge quantity of
this resource in the area but lately they were consuming wood chips because the feed-in tariff were higher. Since some months
ago the law changed and now all the biomass are paid the same so some of them are coming back to the olive cake, others are
still consuming woodchips but until some months we won’t have a clear picture of the real mix.
