Helsingin Energia’s environmental experts are
active in national and international committees. These bodies come
under sector organisations, such as Finnish Energy Industries, VGB
and Eurelectric. Common positions regarding preparation of
directives were discussed with both Finnish ministries and EU
institutions. Helsingin Energia’s persevering energy efficiency work
plays an important role in renewal of energy conservation agreements
with both cities and energy companies.
From the viewpoint of Helsingin Energia’s
operating model, it is important to draw due attention to the
position of combined generation of power, heat and cooling in the
national emissions allocation plan for the next Kyoto period,
2008–2012. The EU has also emphasised the significance of combined
heat and power generation for reaching the energy efficiency goals.
‘Common stack’ interpretation problem
In 2005, the European Commission gave a new
interpretation of the Large Combustion Plants Directive (LCP).
Separate boilers located in the territory of one plant were
considered to form one combustion plant, if the flue gases of these
boilers are led to one stack, even if through different smoke ducts.
The interpretation poses a problem to Finland, as emission limits
would in this case be determined according to the combined rated
thermal inputs of the boilers in the plant territory. High-capacity
plants have strict emission limits.
Originally the Commission was not familiar with
the Nordic district heating system which requires peak power for a
short period of the year. Heat is mainly generated by means of
eco-efficient CHP production. During the coldest periods, boilers of
peak-load heating plants are started up according to need. Their
operating time is usually only 100–200 hours per year, due to which
also their effects on emissions and air quality are insignificant.
In autumn 2006, the common policy of the energy
sector and the environmental authorities was confirmed by the
Government and presented to the Commission, which launched a
consultant study of the subject. This brings the functional energy
solutions of Finland and Helsinki to wider European attention.
Effect of the selected heating method
Calculating emissions from heating and cooling on
the basis of their production form is not as unambiguous as in the
case of electricity. Helsingin Energia has been involved in
preparation of a European standard which defines the bases for
calculating the effect of real estates’ heating method choices on
primary energy consumption and carbon dioxide emissions, which means
that the entire energy chain from consumption to production and the
electricity market are taken into account in the calculation.
Environmental constraints for the
According to the draft component master plan for
the Sörnäistenranta and Hermanninranta areas, which was discussed
during the year under review, also other than industrial use is
planned for the area. According to the City Council’s decision, the
Hanasaari A power plant will be demolished and the existing open
coal yard area released for other use. At the same time, replacement
coal logistics for the Hanasaari B power plant will be implemented.
In 2006, constraints for these projects with respect to
environmental effects, safety distances and implementation of
long-term energy supply were looked into with Helsingin Energia and
other co-operation parties.
In this connection, preparations are made for
treating contaminated earth masses, since this has been necessary in
the area’s previous construction projects as well. It is important
to determine the nature of contamination and the size of the area.
So far, soil testing has given no overall picture of the situation
in the area, and tests will be continued. When the Hanasaari A power
plant was built, asbestos was commonly used in structures. During
demolition, asbestos will be removed according to orders of the
