Improvement of electricity supply reliability
The uniqueness of the climate in the Northwest of Russia is determined by the specific geography in high latitudes and north to south and west to east extension of the federal district.
The following natural disasters can occur in the Northwest of Russia:
- hurricanes (storms);
- low winter temperatures, snowfalls with sleet sticking to electricity transmission lines;
- spring high water (area flooding during the high water period);
In 2015, the Company did not have any technogenic or natural emergencies and no disasters occurred in 2015 in the spring high water period. From May through September 2015, thunderstorms were reported in the Vologda, Pskov, and Novgorod Regions, and the Republic of Karelia. Wind outbursts exceeded 20m/s which resulted in complex technological disturbances. These disturbances were remedied by the Company’s field emergency repair crews and the Company’s contractors within an established period of time.
Taking into account the geography of the region, forests, and climate conditions in spring-summer period, wildfires represent a hazard in the area serviced by the Company: mainly in the Arkhangelsk, Vologda, Pskov, and Novgorod Regions, as well as in the Republic of Karelia, and hard-to access districts. Taking into account the unstable situation in the constituent entities of the region, urgent additional preventive measures are taken to prevent and respond to wildfires.
Significant wear and tear of the Company's and territorial grid organizations' electric grid equipment in areas serviced by the Company is a real threat to a stable power supply to industrial sites and households.
In order to minimize a potential damage from natural and technological hazards the Company conducts trainings in personnel preventive and response measures dealing with accidents and emergencies. For this purpose, the Company:
- sets up and maintains Headquarters that have experience in developing and making decisions in case of power supply disturbance, etc., as well as powers and authority sufficient to engage necessary resources.
- a total of 37 mobile crews are set up and ready to act in order to ensure interaction between the branches, the PJSC ROSSETI’s subsidiaries, and PJSC FGC UES’s branches, plus 66 mobile teams intended to align interaction between the operations units of the Company’s branches.
- mobile team manning standards and standards for the provision of vehicles, tools, gear, communications and funds to a mobile team are outlined.
- a procedure and timeframe are determined for gathering and dispatching a mobile team to a specific area for emergency response.
- mobile crews and gear are placed based on the possibility of fast arrival (delivery) to the work site and availability to start emergency response within no more than two hours after an event.
|Number of teams||Headcount
|IDGC of the North-West||37||223||98|
|Number of teams||Headcount
|IDGC of the North-West||66||397||144|
A redundant power supply sources (RPS) reserve was formed and made available (209 units). Redundant power supply sources are ready to use and placed to make their fastest delivery to the site possible.
A total of 47 contracts (agreements) on cooperation during challenging technological disturbances response operations were signed with contractors.
Preparation of emergency rescue and mobile team leaders is performed in the course of joint drills with Regional power supply security headquarters, territorial executive authorities, local governments, utilities, divisions of Ministry of emergency situation, Ministry of internal affairs, Ministry of Defense, as well as contractors and consumers. A total of 20 drills were conducted.
During drills and exercises, Company management demonstrated excellent professional competencies when developing materials and making justified emergency response decisions. Non-professional emergency response teams (NERT) are available and capable of emergency response.
The Company set a material and technical base with warehouses, storages, open platforms, tanks that satisfy the Company’s needs and are sufficient to accept, stack, and store resources, and respond to emergencies.

The Company implements actions to prevent emergencies and technological disturbances, including:
- monitoring of grid conditions and forecasting complicated technological disturbances, emergencies and accidents;
- regular analysis of emergencies and large-scale technological disturbances to identify their possible causes and development;
- prevention of certain unfavorable and dangerous natural phenomena to the extent possible through regular reduction of their destructive potential (icing, accumulation of snow before electrical towers on slopes, etc.);
- regular improvement of the technological process safety and operational reliability of equipment;
- development and implementation of engineering and technical measures (creation of a required stock of spare parts and inventories, preparation of machinery, etc.);
- exercises, drills, and trainings;
- comprehensive interaction with all entities of the electric power industry;
- scheduled and random audits and examination of equipment, including standby equipment;
- timely recovery of damaged equipment;
- equipping and training of emergency response teams to reduce time from notification to gathering, support of technological disturbance response within the time stipulated by PJSC ROSSETI requirements.
The Company has actions in place that will minimize the risk of emergencies and large-scale technological disturbances at electric grids and reduce the response time. Operating divisions’ and distribution zones’ emergency repair data sheets are generated and updated on a regular basis.
