Ardor’s hybrid battery-and-solar plant clears more than 80 000 € within weeks of going live

When pellet producer Ardor switched on its new one-container battery in early February, just days after Estonia left the IPS/UPS grid, the first aim was simply to keep factory operations stable through a turbulent period for the Baltic power system. Since then, the company’s on-site solar park and storage unit have already earned well over 80 000 € in market revenue by combining frequency-restoration services for Elering with carefully timed charge–discharge cycles on Nord Pool.

“Construction hit every milestone; the only piece that took a little longer was setting up the energy management and metering system,” says CEO Kuido Kuntro.

“Today, the market is facing a significant shortage of flexible assets. It’s important to get started quickly. The battery operation strategy evolves over time and can be fine-tuned in the coming months,” noted Magno Kure, co-founder and CEO of Smartecon.

What Ardor has learned so far

  • Set aside extra time for grid-connection and compliance tests – they often run longer than planned as BESS and PV hybrid is new topic for TSO/DSO.
  • Invest in SCADA monitoring tools and support – better operational visibility turns data into higher profits and asset availability.

Almost half of the project’s capital cost was covered by Estonian Business and Innovation Agency Energy Security grant programme. Encouraged by the initial results, Ardor is already looking at a second storage container and more solar panels to boost both self-consumption and market revenue.
