UA-GRIDEX Project Report: Promoting Resilience and Uninterrupted Access to Essential Municipal Services in Ukraine through Exploring the Potential of Renewable Energy Solutions for a Municipal Water Station

The report evaluates renewable energy options for a municipal water station in Ukraine serving 400,000 residents. It compares 100% decentralised systems (PV+Battery vs. Wind+Battery) and feasible grid-connected hybrid systems, finding that while wind is more cost-effective, solar PV is the only viable on-site installation due to space constraints. For heating, water-to-water heat pumps are identified as the optimal solution. The report also maps international financing opportunities from institutions like the EBRD, EIB, and World Bank to support implementation.

• A comparison of 100% decentralised renewable energy solutions shows that a wind + battery system is significantly more cost-effective than a solar PV + battery system, with a total lifetime cost of €46.2 million and an LCOE of 0.131 €/kWh, compared to €146 million and 0.412 €/kWh for the solar option.
• On-site installation of utility-scale wind turbines is physically unfeasible due to the facility's limited available area of 8,712 m²; a single 2 MW wind turbine would require approximately 170,100 square meters.
• Among the evaluated heating technologies, the water-to-water heat pump (WWHP) is the most efficient and economical choice, featuring the highest coefficient of performance (COP) of 5.515 and the lowest total annual cost of €290,011.
• Integrating solar PV to power the heating system further reinforces the WWHP as the optimal choice, with a total joint system cost of €850,936, which is lower than the costs for air-to-water (€1,112,880) or air-to-air (€1,219,604) configurations.
• The report identifies several feasible grid-connected hybrid solutions; a Solar PV + Grid configuration has an LCOE of €0.113/kWh and relies on the grid for 90.6% of its energy, while adding a battery (Solar PV + Battery + Grid) results in an LCOE of €0.114/kWh.
• The facility's energy resilience is currently limited by legal restrictions that prohibit the export of excess renewable electricity to the grid, leading to significant unused energy in the modelled 100% renewable scenarios (40.5 GWh for PV and 37.4 GWh for wind).
• The estimated cost for a solar power solution at the water station is between €2.5 and 3.5 million, and the report recommends a blended financing model combining loans, grants, and technical assistance.
