Bulgaria Issues 3,000-MWh Energy Storage Tender

• Bulgaria's ambitious RESTORE tender opens doors for 3,000 MWh of renewable energy storage, offering €683 million in grants. Seize the chance to innovate by November 21!

Bulgaria has initiated a tender for 3,000 MWh of new energy storage capacity, supported by the EU, to enhance the integration of renewable sources like wind and solar into its energy mix. Interested applicants can seek grants totaling BGN 1.2 billion (approximately USD 683 million) by the November 21 deadline, with grants covering up to 50% of eligible costs.

The tender, named "National infrastructure for storage of electricity from renewable sources" (RESTORE), is part of Bulgaria’s National Recovery and Resilience Plan. Applicants can submit multiple proposals, although total funding per entity is limited. The projects must be commissioned by March 2026.

How will Bulgaria's energy storage tender impact renewable energy integration and investment?

• Enhanced Renewable Integration: The establishment of 3,000 MWh energy storage capacity will facilitate the smoother integration of intermittent renewable energy sources such as wind and solar. By storing excess energy generated during peak production times, Bulgaria can ensure more consistent energy availability, especially during periods of high demand or low generation.
• Investment Incentives: The availability of grants covering up to 50% of eligible costs significantly lowers the financial barrier for investors. This could attract a range of stakeholders, including private companies, energy cooperatives, and foreign investors, potentially leading to increased capital inflows into Bulgaria’s renewable energy sector.
• Support for Grid Stability: Energy storage systems can help mitigate issues related to grid stability by providing ancillary services such as frequency regulation, spin reserve, and demand response. This is particularly relevant for Bulgaria, where the incorporation of fluctuating renewable resources poses challenges to grid management.
• Regional Energy Security: By boosting energy storage capacity, Bulgaria can enhance its energy independence and reduce reliance on fossil fuel imports. This plays a critical role in security of supply, especially amidst geopolitical tensions that affect energy markets in Europe.
• Long-term Economic Growth: The investment in energy storage infrastructure could create jobs in construction, operation, and maintenance phases. This job creation can have a positive ripple effect on the local economy and foster a skilled workforce in the renewable energy sector.
• Encouragement of Local Innovation: The tender could catalyze research and development in energy storage technologies, encouraging Bulgarian companies to innovate and develop homegrown solutions. This aligns with Bulgaria’s goals of transitioning to a more sustainable energy economy.
• Alignment with EU Goals: By participating in this tender, Bulgaria is aligning itself with the European Union's overarching strategy to reach climate neutrality by 2050. This can bolster the country’s position in EU energy policy discussions and access to future funding for renewable projects.
• Diverse Technology Participation: The open nature of the tender allows for a variety of energy storage technologies to be proposed, including lithium-ion batteries, pumped hydro storage, and innovative solutions such as compressed air energy storage. This diversity can lead to a more resilient energy system.
• Potential for Regional Collaboration: The development of energy storage systems may foster collaboration with neighboring countries, enhancing cross-border energy trading and integration. Such cooperation could stabilize regional grids and lead to better utilization of renewable resources.
• Meeting National Energy Targets: The integration of additional storage capacity can help Bulgaria meet its national renewable energy targets, contributing to EU-wide objectives and enhancing the country's reputation as a leader in renewable energy deployment in Southeast Europe.
• Environmental and Social Benefits: Increased use of renewable energy and efficient storage solutions will help decrease Bulgaria's carbon footprint and move toward a more sustainable energy future. This shift can also improve public health by reducing air pollution associated with fossil fuels, benefiting communities across the nation.
