ČEZ Energo has expanded the range of Czech flexibility aggregators - it delivers services for system stabilization through the Flexigy platform.

ČEZ Energo has become one of the most important flexibility aggregators on the market. Thanks to the implementation of the innovative Flexigy platform from Unicorn Systems, the company now has the opportunity to offer the market a portfolio of more than 130 gas-fired power and heat generators. This offering represents a capacity in excess of 100 MW, comparable to a single unit of a conventional coal-fired power plant. CEZ Energo is thus entering the market with support services and is positioning itself as an aggregator that will contribute significantly to the balancing of the Czech transmission system managed by CEPS.

Since 2021, the Czech Republic has been legislatively allowed to aggregate flexibility from smaller sources and consumers. Over the last two years, several aggregators have emerged on the market, but CEZ Energo is a leader among them thanks to its advanced grid stabilisation services.

As a technical aggregator, CEZ Energo uses the Flexigy tool to identify available flexibility. Thanks to the advanced prediction and optimization kernel, the optimal composition of 1 MW power units can be found. The information on available flexibility is then transmitted to CEZ's trading department, which then trades it on the energy market.

According to the trading results, the Flexigy system then prepares operating plans for both individual resources and the entire aggregation block. Continuous optimization can also indicate situations when the sold volumes cannot be delivered. In this case, the system will help the dispatcher to adjust the operating parameters so that flexibility delivery is possible.

However, the main added value of the Flexigy platform is the automation of flexibility identification. Thanks to a sophisticated prediction module, the system can identify flexibility for the following hours and days from historical data and weather forecasts. This then allows the optimization algorithm to automatically build bids and operational plans to achieve the most efficient use of the entire resource portfolio.
