This case study explores the Rehabilitation of the Bistrica Hydropower Plant in Serbia, a project aimed at modernizing the plant, which has been operational since 1960.

About
The project involves technical upgrades to enhance the plant’s efficiency and increase its annual electricity production. The initiative is part of Serbia’s broader energy strategy to increase the share of renewable energy sources in its national grid.
Challenges:

The Rehabilitation of the Bistrica Hydropower Plant project aims to address several critical issues:

  1. The plant, built over 60 years ago, suffers from outdated and inefficient equipment, which has led to reduced performance and frequent malfunctions. The older machinery and technology in use at the plant result in lower energy production and suboptimal use of available water resources.
  2. The current operation of the plant is associated with higher greenhouse gas emissions, which are inconsistent with modern environmental standards and Serbia’s international commitments.
  3. The plant’s diminished reliability poses challenges to Serbia’s energy supply, particularly in integrating renewable energy sources like wind and solar power into the grid. The existing plant setup does not fully align with the latest EU environmental and energy regulations, which Serbia is committed to following.
Solutions

The Rehabilitation of the Bistrica Hydropower Plant project presents several technical solutions to address the identified problems:

‍

The project involves replacing old turbines and generators with new, more efficient models. Alongside the main machinery, auxiliary systems such as control and safety equipment will be modernized to reduce the likelihood of malfunctions and ensure smoother operations.

By upgrading to more modern and efficient technology, the plant’s efficiency is expected to improve by 3-5%, allowing for better exploitation of water resources and more reliable energy output.

The modernization efforts will extend the plant’s lifespan, with the new equipment and systems designed to reduce its emissions, helping the plant meet stricter climate targets.

Impacts

The Rehabilitation of the Bistrica Hydropower Plant is expected to yield several important results and benefits:

  • The modernization is projected to boost the plant’s annual electricity generation from 335 GWh to approximately 350 GWh, enhancing its contribution to Serbia’s energy supply.
  • The project will increase the reliability of the plant, which is crucial for integrating additional renewable energy sources like wind and solar power into Serbia’s national grid.
  • The rehabilitation will align the plant with the latest EU environmental and energy regulations, which is a key step in Serbia’s broader strategy of EU integration.
