Ukraine - South Ukraine Regional Transmission Network Development

NPC Ukrenergo aims at de-bottlenecking the regional network (up to 750 kV) in South Ukraine for more efficient and reliable power supply and at accelerating the integration of solar and wind power into the national power grid within the next 15 years. The Consultant was appointed to assist NPC Ukrenergo to assess the implication of installing sizeable solar and wind power generation capacities in Ukraine.

The project is divided in two phases:

• Phase I: Regional Power Network Development Master Plan and Solar & Wind Power Integration Assessment
• Phase II - Project Preparation of Two Priority Investment Packages.

The assignment has the following main tasks:

• Master planning of the regional power network development at 750, 330, 220 and 110 kV voltage levels in South Ukraine with a 5 and 15-year perspective;
• Determination of the appropriate levels of wind and solar power capacity and appropriate operational and technical parameters for management of such connected capacity;
• Drafting necessary documents regulating technical aspects of solar and wind energy operation in Ukraine;
• Identifying the short and medium-term investments needed to strengthen the regional grid and to increase the capacity of wind and solar power that could be connected in South Ukraine;
• Determination of the required spare generating capacity in an interconnected power system (IPS) based on power balance analysis, type and operational parameters of such generating capacity to compensate fluctuating energy supply by large commercial-scale wind and solar power plants;
• Prioritisation of construction/reinforcement projects to be implemented by 2030;
• Strengthening the Client's capacity to perform better network planning and operation;
• Performing comprehensive technical, economic, commercial and socio environmental feasibility assessment of two projects prioritised among those identified in the master plan.
