Bulgaria on track to add 1.5 GW of solar power by mid-2026

The pace of large photovoltaic projects in Bulgaria indicates that total capacity can reach 6 GW by the middle of next year. The expansion isn’t slowing down.

Investors in large solar power plants in Bulgaria don’t seem intimidated by zero and negative wholesale electricity prices eating away at their revenues. One of the factors is a surge in the construction of battery energy storage systems (BESS), which iron out the gap between intraday peak production and the power demand curve. In a new analysis, Capital.bg estimated that the country’s photovoltaic capacity is set to increase by 1.5 GW by the end of the first half of next year, only accounting for big projects.

The total would reach 6 GW. The report lists 14 projects, of which some are benefitting from BESS grants from one of Bulgaria’s past tenders.

Chinese group building largest current PV project

The biggest solar park under construction is Simeonovgrad-Polyanovo, consisting of two units of 250 MW in total. It is located in the Haskovo region in the southern part of the country.

United Energy Group bought the two projects last year. It it the first significant Chinese investment in Bulgaria, the article reads. The PV plant is expected to be put into operation early next year.

The construction of the first phase of the Tenevo hybrid power plant began almost two years ago

Next on the list is Tenevo. Almost two years ago, Eurowind Energy and Renalfa IPP marked the start of the construction of the solar segment of a hybrid power plant near Yambol. The PV park is envisaged with 237.6 MW in peak capacity and a 213.7 MW grid connection.

The largest solar power plant in Bulgaria is called Apriltsi.

St. George coming online before year-end

Czech company Rezolv Energy bought the St. George project for 229 MW two years ago and broke ground at the construction site last autumn. According to the latest data, the investment is worth almost BGN 1 billion (EUR 511 million) and it is coming online by the end of the year. The developer secured a 199 MW connection.

Greek government-controlled utility Public Power Corp. (PPC) is commissionning its Colosseum (Kolizeum) facility of 165 MW in the coming months, the update reveals. The project in Chirpan has an approved network connection of 120 MW. The company is planning to add batteries of 25 MW in capability and a capacity of 55 MWh.

The company is also building an 88 MW in Vedrare near Plovdiv. The contractor for the facility in the municipality of Karlovo is Chint Green Energy of the Chint Group. The power plant is on track to become operational early next year.

A 123 MW system will be on 400 hectares between the villages of Knizhovnik and Dolno Vojvodino in Haskovo. Austria-based Enery said it would install a BESS of 180 MWh next to its solar park.

Electrohold is testing its Maglizh PV plant, the article adds. The project for 100 MW occupies 127 hectares and the estimated investment is almost EUR 90 million. The plan was changed along the way.

Top Energy Solutions has a construction permit for its Loznitsa project in northeastern Bulgaria. The project is for a peak capacity of 115 MW and a grid connection of 99.99 MW, spanning 82.4 hectares. It is located at the villages of Vesselina and Kamenar in the Loznitsa municipality, Razgrad district.
