We started with inefficient Vilnius district heating sector, and over 15 years, have reorganised and updated the system, introduced advanced technologies, sought expansion of use of renewables and reduction of environmental impact. We have cut losses in heating courses down to 12% from 24%, re-supply of co-generation water to 10 m3 down from 150 m3 per hour, and average cut-off hot water supply during hydraulic tests run in summer down from 100 to 33 hours. Due to our efforts, Vilnius district heating sector is now among most advanced across Europe.
The grid dispatcher station was updated and control of heating supply, real-time, was secured.
Before the dispatcher station was installed, it would take more than 20 minutes to communicate data to the dispatcher station. Once latest technologies such as GIS and RASA were installed, situation can be recorded real-time, which helps detection of any leaks of coolant, changes in temperature, or any major accidents (in older pipelines).
The company has always focussed on the use of renewables for energy generation. Since the early start, we have been working on a clear and single trend, i.e. investment in adjustment of heating sector for consumption of local biofuel. To accomplish that, in 2006, a 60MW biofuel boiler was launched at the second Vilnius cogeneration power plant.
Gas consumption was reduced, and running on biofuel has reduced heating price for customers.
In 2007, Vilniaus energija has invested in a mobile boiler station which ensures heating supply in case of any malfunction in heating course.
Whenever necessary, the boiler station may be set up anywhere in Vilnius, and supply heating to a group of apartment buildings. The boiler is also used during hydraulic testing to ensure an uninterrupted supply of hot water.
In 2009, a smoke condensation economiser was launched at the second Vilnius cogeneration power plant. The device efficiently removes solid particles from smoke and reduces concentration of CO2 greenhouse gas emissions, and further recuperates heating. This has allowed increasing heating capacity of the power plant to approx. 18 MW, without increased fuel consumption.
In 2011, 2 biofuel boilers (with capacity of 6 MW each) were launched in regional boiler station in Naujoji Vilnia. This has reduced gas consumption, increase biofuel consumption , and has reduced heating price.
The company was the first district heating supplier in Europe to use Maximo IBM platform for maintenance and operating processes in the company.
The staff of Vilniaus energija has designed an interactive map on heating consumption which displays energy efficiency of building in Vilnius. The map displays assessment of efficiency of both current heating season and efficiency of a few previous heating seasons. This is especially relevant to potential housing customers or those in doubt of renovation of an old apartment building.
Vilniaus energija has always focused on quality of customer care and improved performance. Now that our professionals have received tablets, they can provide full information required on invoices, payments, and heating consumption, at the time they visit customers, and an opportunity, while visiting heating stations, enter relevant details, complete agenda, and plan further visits.
In 2014, Vilniaus energija scored a Gold medal in the Award of the Product of the Year for environmental accomplishments. A smoke detection system in now installed in the second cogeneration power plant allowing reduction of oxide emissions. This award went to a joint project with the Lithuanian Energy Institute.
In 2015 to 2016, Vilniaus energija has installed low NOx emission burners at the second Vilnius cogeneration power plant. These burners can run on both fuel oil and gas. Due to modern construction of the burners, burning process emits less emissions to the atmosphere.
In 2002 to 2016, heating courses were reconstructed and new courses built.
Over 15 years, the company has replaced and installed almost 150 km of courses, i.e. almost 20% of total heating pipelines of Vilnius.
In the period of 2002 to 2016, seeking reduction of heating losses and elimination of group boiler stations, heating stations were renovated.
An independent system in place allows constant pressure required within system of an apartment building. With the system in place, residents can now activate or deactivate heating of their apartment buildings as they like.
