Energy efficiency

Neste Oil's goal is to reduce its energy consumption, particularly in refining and logistics. Enhancing cost efficiency and low-emission refining are key drivers for improving energy efficiency.

Energy consumption 2014 2013 2012
Total energy consuption, TWh 12.7 14.11* 14.24*
Fuels and natural gas (incl. own fuels used in energy production) 91.5% 91.4% 90.5%
Purchased electricity 6.1% 6.4% 6.9%
Purchased heat 2.4% 2.2% 2.6%

*Energy consumption figures from 2013 ans 2012 include also Neste Shipping.

Neste Oil is committed to Finland's national energy efficiency action program, which is designed to help combat climate change in line with Finland’s national climate and energy strategy. Our national energy efficiency program covers the Porvoo and Naantali refineries and terminals in Finland. Our key target in Finland is to decrease energy consumption by 660 GWh by 2016. This is equivalent to the annual electrical energy needed to heat 35,800 homes, 120 m2 and four family members (source: Vattenfall). As of the end of 2014, 91% (80%) of the energy-saving target set for 2016 has been achieved.

Monitoring energy efficiency at Neste Oil refineries

An international energy efficiency index is used as the measure for energy efficiency at Neste Oil’s oil refineries in Porvoo and Naantali. The Porvoo refinery was given a value of 84.4 (84.0) in 2014, while the Naantali refinery received a value of 98.3 (96.3).

Due to differences in the refining process, the energy efficiency of our renewable fuel plants is measured by kW/ton of output. In 2014, the indicator score was 227 kWh/ton for the Rotterdam refinery and 239 kWh/ton in Singapore.

Development measures taken at our refineries in 2014 will result in an annual energy saving of approx. 76 GWh. Energy efficiency was mainly improved by operational actions, like changing the method of running the compressors at the Rotterdam refinery.

Energy efficiency improved in turnarounds

Refinery equipment is maintained and renewed in regular turnarounds. New equipment often features better efficiency ratios and insulation, which allows decreasing energy consumption. The turnaround at the Singapore refinery in 2014 included modifications of hot oil furnace and the replacement of heat exchangers.

The aim of the turnaround at the Porvoo refinery in 2015 is to deploy new crude oil distillation unit process furnaces. Their deployment is estimated provide annual energy savings of approximately 50 GWh. In addition, the waste heat boiler in the reforming unit will be replaced in the turnaround.

New utility management system facilitates more efficient use of energy

A new utility management system was introduced at Neste Oil's Porvoo and Naantali refineries in 2014. The new system's hourly process unit-specific monitoring allows for the more efficient use of utilities, such as electricity, steam, water or fuels used in energy production. The new system is an excellent tool whose consumption data make it possible to develop the processes and operations to be more cost and energy efficient. In the future, the goal is to review the possibilities for adopting the system in our other production plants as well.

Power plant project increases energy production efficiency and decreases environmental impact

Neste Oil is planning to make a EUR 250 million investment to renew power generation at the Porvoo refinery in collaboration with Veolia and Borealis. The power plant investment will increase the efficiency of energy production and mitigate environmental impact. The intention is to make a final decision on the project in spring 2015; the completion of the new power plant is scheduled for 2017.

Energy efficiency in transportation and station network

The terminals used by Neste Oil's tanker trucks, together with the loads they carry, are designed to be as efficient as possible in terms of energy usage.

In addition to production, we have prepared energy efficiency programs for our station network in Finland, the Baltic countries, and Russia. The aim of the program in relation to the station yards in Finland is to reduce electricity consumption by 25% by 2020 in comparison to 2007 levels. New lighting technology is one of the means used in pursuing the savings. In 2014, we began a switchover to LED lighting at stations owned by Neste Oil in Finland. In 2015, the project will also cover the stations for heavy traffic and stations of owner-merchants. In the Baltic countries and Russia, the lighting changes aimed were almost completed in 2014.

The aim of the energy efficiency program for the station network in the Baltic countries and Northwest Russia is to reduce electricity consumption by 20% (6,800 MWh) compared to 2010 levels by 2020.
