Abstract:
Combined heat and power generation (CHP) has made a considerablecontribution to Dutch national energy efficiency and is an important
element
in future energy and environmental policy programs. Recently, the effect
of
liberalisation of energy markets on prices and tariffs has been signalled
to
form a threat to CHP. This study calculates effects in two-market scenarios
for a wide variety of CHP options and conditions. Results show that
indeed
profitability of investments in CHP has substantially decreased. Even
in a
scenario where electricity prices cover more than just marginal costs,
most
types of CHP are no longer profitable. Cash flow calculations on existing
CHP
projects also show a substantial decrease. Estimates on the national
CHP
capacity for 2010 compared to 1999 amount to a decrease in the competitive
scenario and a stabilisation in the moderate scenario. The main cause
is the
fierce competition on the electricity market and the uncertainty whether
prices will cover more than just marginal fuel costs in the near future.
Part
of the study was also to make an update of the technical and cost inputs
of
CHP projects. Investments and O&M (operation and maintenance) costs
seem to
have risen substantially, contributing to the decrease in profitability
of
CHP. 20 refs.
