Microgrid storage cost breakdown in Bulgaria 2030

How will the selected storage systems be distributed in Bulgaria?

The selected storage systems will be geographically distributed across Bulgaria and connected either to the national transmission grid or local distribution networks. All awarded projects must be operational by March 2026.

How much battery energy Storge capacity does Bulgaria have?

Bulgaria has installed between 40 MWh and 50 MWh of battery energy storge capacity to date. However, new national legislation as well as funds provided through the European Union’s Recovery and Resilience Facility (RRF) could add another 1 GWh of storage capacity over the next two years.

How much does a mini-grid cost?

LCOE of US$0.60/kWh needs to be more than halved to allow for an affordable cost- reflective tariff. Upfront cost per connection for mini-grids is around US$500–2,100, similar to the unsubsidized cost for traditional grid connections. In remote areas, mini-grids are the preferred options for electrification as grid extension costs increase.

What are the different mini-grid cost metrics?

Understanding different mini-grid cost metrics supports informed decision-making. For instance, the levelized cost of energy (LCOE) accounts for all costs spread over the lifetime and load profile of a mini-grid, including capital expenses (CAPEX), operating expenses (OPEX) and therefore is an indicator for the cost-reflective tariff.

How can remote monitoring reduce mini-grid O&M cost?

Remote monitoring of power generation, storage and consumption can cut mini-grid O&M cost by 30% (LCOE by 4%) by reducing the number of site trips and prolonging component lifetime, therefore cutting labor, logistics and component replacement costs. (AMMP, p.7,10,13; RMI, p.18)

How much money does the NRRP provide for energy projects in Bulgaria?

Under the RESTORE initiative, launched through Bulgaria’s National Recovery and Resilience Plan (NRRP), the Ministry of Energy has selected 82 projects that will collectively receive BGN 1.15 billion (approximately $675 million) in public funding.
