Energy investment platform · Latvia · Estonia · Lithuania
Since February 2025 the three Baltic states balance their own power system, and that created a new market for fast, flexible capacity. Invest in Energy opens it to investors: we develop battery storage projects, operate them under our aggregator licence, and offer each one to co-investors as a named, documented investment.

For decades the Baltic power system was frequency-controlled from Moscow as part of the BRELL ring. On 8 February 2025 it disconnected, ran as an island for a day, and on 9 February joined the Continental European synchronous area.
Balancing became a local job overnight. The three transmission system operators, AST, Elering and Litgrid, now procure their own reserves (FCR, aFRR and mFRR) through a joint Baltic balancing market. Every megawatt of reserve has to come from assets inside the region.
Meanwhile wind and solar are being added faster than the grid can absorb them at midday, and evening peaks are still met by imports. Wide daily price spreads follow. Today in Latvia the gap between the cheapest and most expensive quarter-hour is 285 €/MWh.
Those spreads and the new reserve market are what an energy storage investment earns from.
Wind and solar arrive when the weather allows. Demand peaks when people come home. Storage is what connects the two.

A battery energy storage system (BESS) can respond in under a second, charge when power is cheap and discharge when it isn't. That is what makes it an investable energy asset: one battery can stack several revenue lines and switch between them as markets move.
Reserve payments from the TSOs for keeping capacity available for FCR, aFRR and mFRR. This is the line that changed most after synchronisation.
Charging in low-price quarter-hours and selling into the evening peak on the day-ahead and intraday markets.
Payment for energy actually delivered when the TSO calls on the reserve, priced per activation.
For commercial and industrial sites: peak shaving, lower connection charges, backup supply and more value from on-site solar.

Our home market. Latvia sits between the two interconnected neighbours and relies heavily on hydro from the Daugava cascade, which makes its prices closely coupled to Lithuania. Our team is in Riga and holds a Latvian aggregator licence, so we can operate storage in the balancing market directly.

The most closely tied to the Nordic system through two HVDC cables to Finland. As oil-shale generation winds down, Estonia is adding wind and solar quickly, and its price often moves on its own, apart from Latvia and Lithuania.

The largest Baltic consumer and the most active storage builder, with large grid-scale battery projects and fast-growing wind capacity. Its links to both Sweden and Poland make it the region's main gateway to markets further south and west.

We secure land near substations with real connection capacity, and handle permits and the grid connection agreement.
We size power and duration against the revenue stack, choose the hardware and design for safety and long service life.
We supply, install and commission the system with experienced contractors and hand over a fully tested asset.
We bid the asset into balancing and wholesale markets under our aggregator licence and monitor it every day.
Co-investors receive regular reports on availability, activations and revenue for each project.
Output follows the weather, not demand. Storage moves it to the hours that need it.

Midday surplus pushes prices down. A battery buys it and sells into the evening peak.

The Daugava cascade is Latvia's flexible backbone. Batteries add sub-second response alongside it.

Each participation is tied to a named asset with its own site, connection and budget. We share the project file, the assumptions behind the revenue model and the risks before any commitment.

We lease or partner on suitable sites across all three countries. We also build behind-the-meter storage for commercial and industrial users who want lower peaks and backup power.

Latvian electricity consumption reached 596 GWh in October, up 13% on September.
Continental European TSOs approved a two-day isolated-operation test followed by synchronisation of the Baltic grids.
Baltic TSOs set out a market-based method for sharing cross-border capacity for aFRR and mFRR balancing reserves.
The Baltic system disconnected from BRELL, ran on its own for a day, then synchronised with Continental Europe.
Reserves are now procured inside the region. That created a lasting need for fast, flexible capacity.
