Technical policy

The most important challenge of JSC Lenenergo is creation of new power network infrastructure on the basis of innovative development, upgrade and improvement of applied technologies. In the field of technological development the Company aspires to adopt the best Russian and foreign experience.

In 2013 the Board of Directors of JSC Lenenergo approved the Regulations of JSC Rosseti about uniform technical policy in the power network complex (further – the Regulations) as the internal document of the Company (Minutes # 19 of the meeting of the Board of Directors of JSC Lenenergo of 30.12.2013). All projects of JSC Lenenergo on new construction and reconstruction included in the investment program of JSC Lenenergo are implemented with observance of the requirements of uniform technical policy.

The goal of uniform technical policy in the power network complex consists in ensuring increase of reliability and efficiency of functioning of the power network complex in short-term and medium-term prospect at maintenance of the appropriate level of industrial and environmental safety on the basis of the innovative principles of development providing non-discriminatory access to electric networks to all participants of the market.

A specialized scientific and technical council (STC) which considers the issues of research and development, trial operation of equipment and materials during its sessions operates in JSC Lenenergo. In 2013 five sessions of STC were carried out.

Topic

Considered issues:

Integration of technical policy directions in practice

The technical policy is implemented in JSC Lenenergo on a number of key directions, including application of new technologies and equipment in various segments of activity.
