Co-generation plant to be established by Eesti Energia at rapeseed processor Werol will be unique in Baltics

22.02.2011
Eesti Energia will establish, by autumn 2011, a natural gas-fired co-generation plant at the Werol rapeseed oil plant in Jõgeva County which will produce not only heat and power but also energy used to cool Werol's oil. It will be the first tri- generation plant in either Estonia or the other Baltics.

When completed, the plant on the grounds of Werol plant will have an electrical capacity of 4.3 MW, a heat capacity of 1.7 MW and a cooling output of 2.5 MW. The Werol plant will utilize the heating and cooling energy, while the electricity generated will flow into the Eesti Energia power grid.

"Eesti Energia's goal is to diversify the production portfolio, and development of efficient combined heat and power generation plays an important part of this, both in Estonia and in the other Baltic states. We see sufficient potential for establishing small CHP plants with a suitable heating load in small settlements and for industrial enterprises," said Raine Pajo, member of the Eesti Energia management board and the head of the Electricity and Heat Generation Division.

In the course of the project, the existing Werol boiler plant will be modernized and it will become part of the new energy generation complex. Eesti Energia's investment is worth slightly more than 5 million euros.

"The Werol rapeseed oil plant has stable demand for heating, which makes the plant economically appealing as the location of a co-generation plant. The rapeseed oil production process requires cooling as well as heating – the absorber device which is a component of the plant, and which is unique in the Baltics, allows cool air to be produced as well. The project will benefit both parties, allowing the plant to focus on its main line of work, while Eesti Energia can utilize the stable demand for heating energy for generating power in CHP mode," added Pajo.

AS Werol Tehased was founded in 1997 and launched rapeseed oil production in December 1999. In 2011, the plant will launch an addition that will nearly double its heat consumption. Two-thirds of Werol's output is expeller cake and one-third is rapeseed oil.

Eesti Energia's first foray into the field of mini-CHP plants came in 2009, when it bought two natural gas-fuelled co-generation units located on the territory of BLRT in the Kopli district of Tallinn. In January 2011, Eesti Energia acquired a Latvian heating company, now called Enefit Power&Heat Valka, which by 2012 will build a new CHP plant that runs on bio fuel and will supply heat to the city of Valka.
