Czech start-up Delta Green secures EUR 2.2 million

In short

• Czech energy technology start-up Delta Green has obtained an investment worth EUR 2.2 million.
• The round was led by Tilia Impact Ventures, along with Credo Ventures and Purple Ventures.
• The financing will accelerate the company’s expansion in Western Europe and help it scale its sustainable energy management solution for households.

Their story in the background

Delta Green is a Czech energy company that aims to enable households to use electricity efficiently and responsibly. Founded in 2008 as Nano Green within the Nano Energies group, the company changed its name to Delta Green in 2024. Its co-owners are David Brozik, Prokop Cech, Lukas Benes and Jan Hicl.

In addition to energy supply, it offers automated solutions for managing electricity consumption and production.

Its solution enables the integration of renewable energy sources (RES) into the grid while maintaining grid stability. The company also focuses on including households, which together create a large virtual battery, in the network balancing process. This approach includes managing both electricity consumption and production, as well as strategically integrating households into grid balancing efforts.

This year, the company announced a successful pilot test involving the participation of households in network balancing.

The bigger picture

Electricity networks are essential to energy systems and play a key role in the energy transition by facilitating the use of renewable energy sources.

According to McKinsey & Co. the transition to renewable energy combined with economic growth will likely result in rapid growth in electricity. Electricity networks will need to expand to meet growing demand for electricity and renewable energy: to achieve net zero emissions by 2050, countries will need to double their investment in transmission lines and other infrastructure to €550 billion a year by 2030.

In your own words

“Our goal is to be a catalyst for energy innovation for households across Europe, and this investment is a significant step towards that vision,” explained Delta Green co-founder Jan Hicl.

“Our first step will be to introduce a service for Czech households to aggregate several dozen megawatts,” explains Delta Green co-founder David Brožík.

The company estimates it will need about 200 households per megawatt.

Investor’s perspective

“To clean up the carbon footprint of our energy sector, we need more renewables on the grid. However, wind and solar are unpredictable, which creates energy fluctuations that need to be balanced,” said Andrew Gray, general partner at Tilia Impact Ventures.

“Delta Green has developed a low-cost solution to this problem and we believe it could be a key piece of the puzzle to increasing renewable energy generation and lowering electricity costs for everyone. We are excited to partner with them on global growth,” Gray added.
