• In 2015, 15 transformer substations were reconstructed • Substations, lines, and other facilities age and naturally wear, so investments in the network facilities are continued with rather high intensity Concern for smaller ones

• In 2015, a total of 6,000 special wire markers, stork protection devices, additional insulators were installed and 121 nesting-boxes for kestrels were mounted • Works amounting to EUR 164,155 were performed • A monitoring plan was drawn up in order to assess the impact of the newly constructed and operating lines – LitPol Link and Klaipėda- Telšiai The sense of community and social responsibility - The website www.elektrosistorija.lt, which is designed to provide, in simple terms, general knowledge on the members, a brief history and present time of the electricity system, currently operating power stations and assurance of electricity demand as well as key development aspects - For four consecutive years, Litgrid employees plant forest trees on the occasion of the professional holiday of Power Engineer's Day - During 2015, the company received 25 groups of visitors who were interested in the electricity system and the strategic interconnection projects and learned about the specifics of the work of energy professionals - Attention to the activities of Litgrid from officials of various countries and experts and high-rank executives of international organisations brings Lithuania into an international focus www.elektrosistorija.lt Traditional forest planting 25 tour groups

To manage risks more efficiently

To raise the quality standard for contract work The expected result – better quality

High-quality and reliable expert examination of projects

The procurement of works is based on the Updated standard design principle of economic and work contracts efficiency

The enhancement of Contract termination technical supervision and option occupational safety quality Financial results

• Litgrid will pay EUR 0.0091 per share in dividends • Lower costs due to more efficient operating costs and ITT management • The asset value reduction after the asset evaluation performed in 2014 led to lower depreciation costs • The subsidiary Tetas operated profitably and paid dividends in 2015 Key financial indicators 19% reduction in transmission tariff rate Without regard to the result of asset depreciation

Ignalina NPP transformer substation reconstruction

Vilnius junction strengthening Reasons for Vilnius junction strengthening

Growing demand • Today, the demand of Vilnius region accounts for one third of the national capacity demand

Decreasing production • Electricity production at Vilnius power plants decreases

Synchronisation • The synchronisation of Lithuania's electricity system with СEN and de- synchronisation from IPS/UPS Projects

The construction of the 330 1 kV electricity line Vilnius – Lithuania Power Plant Vilnius transformer 2 substation strengthening The construction of the 110 3 kV electricity line Neris – Baltupis and reconstruction 4 of the 110/10 kV Baltupis transformer substation The construction of the 330 kV electricity line Vilnius – 5 Vilnia – Neris (with installation of Vilnia transformer substation 330 kV switchyard) The reconstruction of Neris transformer substation The reconstruction of INPP transformer substation

In operation since 1981 For new customer • The condition of the facilities connection is critical and requires major • The nuclear fuel storage will repair be connected here Strongly integrated with the Belarusian electricity system • Non-adapted for the isolated operation of the Baltic countries and asynchronous operation of the Baltic electricity systems with IPS/UPS The projects important to Lithuania are in the list of Europe's common interest projects
