G Energy Solutions Warns Grid Constraints Could Limit Benefits of Battery Expansion in Romania and Bulgaria

Electricity suppliers must increasingly combine renewable generation, battery storage, market trading and risk management to deliver competitive power procurement solutions for industrial customers, according to Romanian energy company G Energy Solutions.

Ionuț Vasilică, CEO and Co-Founder of G Energy Solutions, outlined the company’s approach during Energy Week Western Balkans 2026.

The company operates in Romania, Bulgaria and the Republic of Moldova and is exploring further expansion into neighbouring electricity markets.

Vasilică argued that electricity procurement decisions should be based on a detailed understanding of customers’ consumption profiles and commercial requirements rather than focusing exclusively on the source of generation.

For industrial consumers, electricity costs depend on more than the wholesale market price.

Suppliers must also manage variations in consumption, renewable production forecasts, balancing exposure and the cost of securing electricity over different periods.

The growing deployment of renewable generation and battery storage

The growing deployment of renewable generation and battery storage is changing how these risks can be managed.

Solar and wind projects provide opportunities for long-term electricity procurement, but their output does not necessarily match an industrial customer’s demand throughout the day.

Battery storage can help manage some of these differences by shifting electricity between periods, although it cannot eliminate all supply risks.

Vasilică highlighted the importance of access to liquid day-ahead and intraday electricity markets.

These markets allow suppliers to adjust positions as forecasts change and manage the difference between contracted electricity volumes and actual consumption.

He also stressed the importance of market coupling.

Romania’s coupled electricity borders with Hungary and Bulgaria support more efficient trading by allocating cross-border transmission capacity together with electricity transactions.

This makes it easier for suppliers to manage electricity portfolios across neighbouring markets.

The availability of long-term hedging products

However, the availability of long-term hedging products remains another important consideration.

Suppliers offering multi-year electricity contracts need instruments that allow them to manage future price exposure.

Where markets are fragmented or hedging opportunities are limited, suppliers may need to charge higher risk premiums or offer shorter fixed-price periods.

For industrial customers, these limitations can affect the commercial attractiveness of long-term renewable electricity agreements.

Guarantees of origin as part of renewable electricity procurement

Vasilică also discussed guarantees of origin as part of renewable electricity procurement.

He stressed that these certificates must be distinguished from carbon credits and supported by credible issuance and recognition arrangements.

For companies seeking to substantiate renewable electricity consumption, the contractual treatment and eligibility of guarantees of origin are important considerations.

The combination of renewable generation, storage, trading and certification is creating a more complex electricity procurement environment.

For Romania’s industrial electricity consumers, Vasilică’s assessment highlights the importance of integrating these elements into a coherent supply strategy.

As the electricity system becomes more dependent on variable renewable generation, the ability to forecast, hedge and manage electricity portfolios efficiently could become an increasingly important competitive factor for suppliers and their customers.
