Scope of Work |
The aim of the project is to construct a
combined heat and power plant (CHP) with a fluidized bed boiler including a
reheater and a back-pressure turbine. Fluidized bed combustion technology for
peat-fired plants enables these plants to meet emission requirements. The
plant will be fuelled mainly with milled peat. The peat handling system will
store peat sufficient for 24 hours operation at the site. Heavy fuel oil will
be used as auxiliary fuel during start-ups and periods of low load. The most
viable concept is a centralised 10.2 MW/29 MWth thermal peat-fired
base load back-pressure power plant. Currently, the Republic of Karelia is dependent
on imports of electricity (43% of demand was covered by imports in 1996) and
fuels (heavy fuel oil, diesel, coal, gas). As a result of changes in the
Russian economy and its energy system, the future availability of
electricity, coal, and oil at affordable prices for the Republic of Karelia
is expected to diminish. This kind of development would cause a major shift
towards the utilisation of natural gas and, in deficit regions such as the
Republic of Karelia, local energy resources such as peat, both in power
generation and as substitutes for other forms of energy. The construction of
the Olonets power plant would make use of local fuel resources and improve
the level of self-sufficiency in energy production. The Finnish appraisal of the Russian feasibility
study showed the viability of base load peat-fired CHP plants of selected
sizes. In selecting the plant concept, attention was paid to efficiency,
availability, requirements for proven technology, easy maintenance, positive
environmental impacts, and operational flexibility. The site selected by the municipal
authorities for the plant is about 2 km south of the town of Olonets. The
site is considered acceptable. It is close to peatland areas, which
guarantees unproblematic peat transport, but it is far from the town border. District
heat transmission investment costs would be lower for a site closer to town. |

Project Cost and Financing |
The financial and economic analysis
compared two different future district heat production alternatives, and
determined their financial and economic feasibility. The base concept is a
centralised 10.2 MW/29 MWth thermal peat-fired base load back- pressure power
plant, and the other concept a centralised option, local heat-only boilers
using light fuel oil as fuel. The financial analysis showed that the
financial internal rate of return (FIRR) of the CHP plant alternative on
total capital (equity and debt) is approximately 13%, at an 8% discount rate.
The FIRR for heat only boiler plants was negative. A vital issue for the
profitability of this project is formed by the possible changes in sales
prices of electricity and district heat in relation to fuel prices and
changes in the sales volumes of electricity and district heat. The total cost of the project is 36
million USD. The Finnish-made appraisal study proposes that 30% of the
Olonets peat power plant should be financed with equity and 70% with credit. The
debt would be serviced, and the operation of the plant would be paid by
income from heat and electricity sales. |
