Ukraine’s ESCO success story: How UNDP helped mobilize $24 million in private investment in wartime

November 6, 2025

When missiles began targeting Ukraine’s power grid, the country faced a stark choice: abandon long-term sustainability goals or double down on them. Ukraine chose the latter – mobilizing over $24 million in private investment for energy efficiency projects during its darkest hours.

This achievement emerged from a partnership between the Global Environment Facility (GEF), the United Nations Development Programme (UNDP) and Ukraine’s State Agency of Energy Efficiency. They utilised the ESCO (Energy Service Company) model, a financing mechanism that allows municipalities to upgrade infrastructure without needing to pay upfront costs.

Even as air raid sirens interrupted planning meetings and power outages became routine, this partnership helped transform Ukraine’s approach to energy independence, proving that crisis can accelerate – not halt – systemic change.

Rewriting the Rules in Record Time

By 2023, Ukraine’s ESCO market had nearly collapsed. The procurement process, designed for peacetime, required three years of historical energy consumption data – an impossible requirement for communities facing constant bombardment and blackouts.

The UNDP team saw an opportunity in the crisis. Working with Ukraine’s State Agency of Energy Efficiency, they helped slash the procurement timeline from nine months to just three, creating a fast-track mechanism that could respond to wartime urgency while maintaining transparency and accountability.

They also advised and pushed for legislative reforms allowing cities to install solar power stations at municipal facilities – making critical infrastructure independent of the vulnerable main electricity grid and immune to the blackouts that had paralyzed communities across the country.

Five Paths to Energy Independence 

Across 44 partner cities, the project pioneered five distinct ESCO approaches tailored to Ukraine’s wartime needs:

  • Classic thermal modernization improved building insulation and heating efficiency in structures damaged or  currently place a significant burden on local budgets due to inefficient heat consumption.
  • Solar power installations provided hospitals and water treatment facilities with reliable backup power.
  • High-efficiency water pumping systems are reducing electricity consumption by up to 50%, cutting costs while ensuring communities maintain access to clean water.
  • Street lighting modernization is delivering similar 50% energy savings while improving safety in cities navigating frequent air raid warnings after dark.
  • Enhanced partnerships allowed municipalities to contribute funds or equipment and share in the resulting savings – distributing both costs and benefits across stretched wartime budgets.

To support implementation, UNDP partnered with German development agency GIZ to create an online learning course on municipal energy management, which is constantly available from the Prometheus platform. This training ensures local governments can manage these complex systems effectively despite staff shortages and displacement.

Making Investment Possible in Impossible Conditions

The most remarkable achievement wasn’t the technology – it was convincing private companies to invest in Ukrainian public infrastructure while the country was under attack.

UNDP created two innovative financial mechanisms that transformed risk into opportunity:

  • The Financing Support Mechanism, established with Ukraine’s Decarbonisation Fund, offers loans at just 7% interest for up to 10 years with flexible collateral options tailored to local ESCO companies. By mid-2025, it had evaluated loan applications worth $350,000.
  • The Affordable Finance Facility (ESCO Fund), created with the Business Development Fund, provides partial compensation of the loan principal for ESCO at an annual interest rate of 7–9% loan guarantees to reduce financial risk. Within three months of launching, 15 ESCO companies applied for loans across 30 projects. Fifteen were approved for $1.69 million, with nine already financed. By mid-2025, the fund was considering five additional projects worth up to $500,000.

These mechanisms didn’t just sustain the market – they proved the private sector’s confidence in Ukraine’s long-term future, even as Russian forces continued their assault.

Monitoring Systems That Tell the Truth

In three communities, UNDP installed Automatic Energy Monitoring Systems that collect real-time data from municipal buildings. This transparency revolution enables cities to identify waste, justify investments, and optimize consumption with unprecedented precision.

Early results show these systems reduce annual energy costs by 5-15% through better management of high-consumption equipment like climate control and refrigeration units, faster detection of equipment failures and pipe bursts, and behavioural changes among staff who can now see the impact of their energy choices.

Impact at Scale

Between 2024 and 2025, the numbers tell a powerful story:

  • 138 ESCO pilot projects launched across 47 cities, achieving a direct reduction of 16,052 tons of CO₂ emissions – projected to reach 69,190 tons over 20 years.
  • 87 solar power stations now provide energy security to hospitals and water facilities, ensuring uninterrupted service during blackouts.

  • 58 participants from 23 communities toured successful ESCO projects in September 2024, inspiring six communities to launch their own energy service tenders.
  • 20 veterans and women completed pilot training in solar power plant installation through the “Creating Employment Opportunities for Veterans and Women in the Energy Sector” programme, gaining hands-on skills for Ukraine’s post-war green economy.

Among the supported ESCO projects are three high-efficiency water pumping systems, which are expected to reduce electricity consumption by up to 50%, and one street lighting modernization project – also projected to achieve up to 50% energy savings.

Building a Legacy Beyond Borders

In January 2025, the Ukrainian ESCO Association joined the Global ESCO Network, presenting the country’s wartime energy transformation at a UNEP Copenhagen Climate Change Centre webinar. By May 2025, UNDP's facilitation model was showcased at the 2nd International ESCO Symposium in Istanbul, where leading ESCO companies and market experts recognised Ukraine's progress as a blueprint for crisis response.

The ESCO Registry, a digital tool developed by UNDP with the State Agency on Energy Efficiency and Energy Saving, is complete and expected to launch in 2025. This platform will enable the transparent registration of potential energy service projects and providers, building trust between municipalities and businesses while aligning Ukraine's regulatory framework with EU Directive 2012/27/EU requirements.

A Model Forged in Crisis

The GEF-UNDP project achieved something extraordinary: it transformed wartime constraints into a catalyst for reform. Concluding in December 2024, with efforts continuing through UNDP's Green Energy Recovery Programme in 2025, the project streamlined bureaucracy, de-risked investment, and proved that private capital will flow toward resilient solutions even under bombardment – creating a model for countries worldwide facing crisis or conflict.

As Ukraine looks toward reconstruction, this legacy will endure – in every solar panel powering a hospital through a blackout, every kilowatt-hour saved in a modernised building, every community that took control of its energy future when the alternative was helplessness.

The next phase requires scaling and improvement of the financing mechanisms, attracting more companies to the market, and encouraging international investors to embrace the ESCO model. 

But the foundation has been laid. Ukraine has shown that sustainability isn’t a luxury reserved for peacetime – it's a strategic imperative that becomes most critical in crisis.

When the war ends, Ukraine won’t just rebuild. It will emerge more efficient, more independent, and more resilient than before the first missile struck.
