The outbreak of hostilities in Ukraine was a wake-up call for the Baltic nations, signaling the pressing need for modifications to power insurance policies.
“The power disaster following the aggression of the Russian Federation towards Ukraine in 2022 for certain had an influence on all neighboring nations,” Andres Meesak, sensible power options lead at Estonian regional distribution system operator (DSO) Viru Elektrivõrgud, advised.
The Baltic states of Latvia, Lithuania, and Estonia have realized a terrific deal from the unlucky expertise of Ukraine, as they need to additionally stay within the shadow of its belligerent Japanese neighbor.
“The primary constructive influence has been understanding the menace to power infrastructure and utilizing power and power infrastructure as a hybrid weapon towards societies by the aggressor,” Meesak mentioned. “The battle compelled the nations to hurry up separation from power cooperation [with the Russian Federation] of any form—frequency stability, gasoline provision, electrical energy transit.”
Circuit breakers
Most European nations were once considerably dependent on Russia for power; however, for the Baltic nations, this challenge has a special dimension. The three nations stay a part of the Soviet-era “BRELL” circuit, with Russia and Belarus, counting on Russian operators to manage frequency steadiness and demand.
In 2018, Latvia, Lithuania, and Estonia hammered out a plan to decouple from BRELL and be part of the EU energy grid by late 2025. The events in Ukraine compelled the nations to rethink the time frame and pace up the transition. Different steps are additionally needed to enhance the safety of their power grid.
“The struggle towards Ukraine demonstrated the weaknesses of centralized power provided in comparison with the distributed era in smaller models,” Meesak mentioned, suggesting that it impacted society in any respect range, from households to prime authorities officers.
Along with the political rationale, Baltic traders obtained robust financial incentives to put money into solar energy as power prices within the area went by the roof. At the peak of the 2022 European power disaster, electrical energy customers noticed their payments rise practically sevenfold, in contrast with the earlier year.
Towards this background, the years 2022–2024 have seen solar energy era development throughout the Baltic area beat even probably the most optimistic forecasts.
The uptake of PV has taken off in Estonia. Mihkel Annus, chairman of the Estonian Renewable Vitality Chamber, mentioned that put in capability has doubled every year. In solely 5 years, as of the top of 2023, total put-in photovoltaic capability stood at 812 MW, up from 39.6 MW in 2018.
Lithuania exceeded its 2025 goal for solar energy era, of 1.2 GW, in 2023, in accordance with information from the Lithuanian Vitality Company (LEA). The nation has welcomed practically 300 MW of recent capability over the past couple of years.
In Latvia, roughly 300 MW of photo voltaic capability was put in as of January 2024, mentioned Anna Rozīte, head of enterprise growth for AJ Energy Group. This determination has roughly tripled since May 2023 alone.
Solar energy loved an funding increase in Latvia and different Baltic nations as market gamers primarily opted for options that might be applied as rapidly as possible.
“Photo voltaic panel installations are, in all probability, the quickest tasks, from an implementation standpoint, together with the comparatively quick interval for technical design stage and allowing, in addition to the supply of obligatory tools,” Rozīte defined.
Upward development
Market gamers imagine the expansion skilled thus far may solely be the prelude to an actual Baltic photo voltaic increase within the coming years. The PV potential of the Baltic nations is estimated at 40 GW, according to Rachel Andalaft, managing director of REA Seek. She added that the inexperienced power sector within the Baltic nations is predicted to draw €150 billion ($162 billion) of funding alternatives within the subsequent 20 to 25 years.
It’s anticipated that photo voltaic business growth will probably be accompanied by the deployment and integration of battery power storage techniques (BESS), enhancement of interconnections with different European nations, and the required emergence of a marketplace for energy buy agreements (PPAs)—the good thing about a decentralized era panorama, mentioned Andalaft. And there may be already a major quantity of capability within the pipeline.
Based mostly on official information from Elering AS, the nationwide transmission system operator (TSO), practically 3.5 TWh of photo voltaic power manufacturing will be added to the Estonian power combine by 2026. Native market gamers indicated that this might probably cover half of Estonia’s annual electrical energy consumption. Nonetheless, various huge tasks from 2022 haven’t gone away. The commissioning of solar energy vegetation can take as long as two years, for tasks with as much as 15 MW of capability, to attach on the DSO degree, and greater than three years for tasks above 15 MW to attach on the TSO degree, mentioned Gatis Macans, government director of the Latvian Photo voltaic Vitality Association.
“After the renewable hype in 2022, when there was excessive competitors to e-book grid capability, in 2023 we began to see newly constructed solar energy vegetation primarily related to the distribution grid with capability as much as 15 MW. Nonetheless, a lot bigger PV tasks are below growth and we hope to see just a few commissioned tasks within the next two years,” Macans mentioned.

“[In 2024 and 2025], a minimum of two to five extra solar energy parks must be constructed [in Lithuania] than have been built your entire interval till then,” mentioned Tomas Janususkia, an affiliate accomplice with Widen, a Vilnius-based legislation agency.
The photo voltaic frenzy is seen at each degree of the economic system. Shoppers put in twice as much residential photovoltaic in 2022 alone as in your entire interval earlier than that, Janususkia mentioned, including that households in Lithuania are eligible for state help on photovoltaic installations as much as 10 kW in dimension, whereas, for businesses, the determine is about 500 kW. Streamlining laws for renewable-era installations has additionally had an impact.
“The present authorized regulation has principally simplified the development of solar energy vegetation,” Janususkia mentioned. “It doesn’t require both spatial planning paperwork, environmental influence evaluation—aside from distinct instances—or land-use change. The launched mannequin of the hybrid energy plant, along with wind energy vegetation or accumulators, considerably facilitated and made using electrical energy networks and hundreds extra environment friendly.”
Overcoming obstacles
Regardless of progress, challenges for the Baltic photovoltaic business remain. Several components may jeopardize additional capability development, primarily fears that having a lot solar energy within the power combine could also be tough.
“The problem [for Estonia] is now to suit manufacturing to demand,” mentioned Meesak. BESS may play a key position, he claimed, including that the business can see how numerous renewable power parks have grown in significance, with photo voltaic, wind, and storage complementing one another.
“Though in 2024 we will anticipate having several hours where photovoltaic power output exceeds the entire electrical energy demand in Estonia, it’s nonetheless an unrealistic expectation to say that, in 2026, a minimum of 50% of demand will probably be lined by photovoltaic, on account of the comparatively low-capacity issue [actual output versus the theoretical maximum] and elevated electrical energy demand in darker and colder winter months,” Annus mentioned. In consequence, the daytime spot costs throughout sunny hours are decreased and extra unstable, he added.
The utmost winter consumption in Estonia is about 1.6 GW. Stakeholders are taking a look at including battery storage in their techniques or optimizing the positioning of panels to extend the value from the market. Meesak mentioned that reducing battery storage prices motivated households to put in extra hybrid photo voltaic techniques with native storage, providing some autonomy in case of energy cuts.
“The day-by-day demand-supply curve reveals potential for inexpensive four- to six-hour native storage; the market value for electrical energy is highest throughout the night hours, proper after PV vegetation fades out, as much as about midnight. To even out the provision and demand, and through that, additionally, the market value, four- to six-hour storage at a cheap price is required,” Meesak mentioned.
REA Seek’s Andalaft mentioned that she agreed that “storage services are completely essential to increasing the penetration price of renewables while conserving grid stability, on one aspect, and enabling new operational modes on the other.” Andalaft additionally believes there are different points that have to be tackled to ensure photovoltaic business development in the long term.
“Demand follows insurance policies,” she mentioned. “Within the pandemic interval, we noticed peak costs each in [capital expenditure] and in electrical energy. The market immediately continues to cope with the aftermath of this. If, throughout the pandemic, the deployment suffered delay and constraints, immediately the shortage of a dynamic PPA market is limiting the funding urge for food and holding back the potential for a various and private-equity pushed, aggressive power panorama.”
In Lithuania, photovoltaic business growth has additionally confronted some sudden bureaucratic obstacles.
Janususkia defined that below the power communities mannequin launched within the nation, customers, power communities, and huge electrical energy producers should connect with restricted power infrastructure networks concurrently. Because of this, quotas have been assigned to community capability.
“This resulted in a sequence of authorized disputes over grid energy shortages for energy producers, acting as a brake on photovoltaic funding,” defined Widen’s Janususkia. “At the moment, these points have been partially resolved; however, the depth of funding has decreased considerably, and the obtainable tasks available on the market will not be in a rush to be applied.”
Regardless of these challenges, market gamers say that they continue to be assured that nothing can derail the photovoltaic business’s development within the Baltic area within the foreseeable future.
