Bulgaria’s transmission system operator ESO has invested more than 182 million euros in network modernisation since the start of 2026. The work includes construction and reconstruction of more than 120 kilometres of transmission lines.
OKTA’s net profit rose to €34.1 million in the first nine months of 2026 from €7.3 million a year earlier, while sales revenue more than doubled. Expenses also climbed, increasing 101% to approximately €891 million.
The Energy Community Secretariat warned that carbon-related costs on electricity exports to the EU could take effect before Western Balkan markets are fully integrated. An exemption for electricity is conditional, and proposed changes to the CBAM framework had not been enacted by early November 2026.
Montenegro’s Environmental Protection Agency has given Nu Energy two years to submit a full environmental impact assessment for its proposed Velestovo solar-and-storage project. The agency will decide whether the 60 MW scheme can proceed after reviewing its environmental effects.

Battery storage can make renewable electricity more predictable for Serbian exporters and improve the commercial case for renewable projects. It does not reduce embedded emissions by itself or replace CBAM evidence requirements.
Around 2 GW of battery storage connection agreements were reported in Serbia in 2026, but the first standalone projects still need to establish a local financing template. EMS requires a construction bank guarantee before transmission-connected projects can advance to connection contracts.
Battery operators across Southeast Europe are increasingly buying solar-heavy midday electricity and shifting it for sale in later hours, with Bulgaria leading the trend. Serbia has begun recording negative day-ahead prices, which can provide a variable source of low-cost electricity for storage.
North Macedonia is structuring its planned 100 MW / 400 MWh Bitola battery as strategic grid infrastructure, with an estimated cost of EUR 98 million. The EBRD is considering a sovereign-guaranteed loan of up to EUR 33.1 million, alongside other expected financing.
Serbian industrial companies must weigh owning batteries against buying flexibility as a service. The choice depends on whether factory-specific savings or market optimisation provides most of the battery’s value.
