Enery Signs Second Corporate PPA with Coca-Cola HBC Bulgaria for 122 MWp Knizhovnik Hybrid Plant

Enery, an independent power producer active across Central and Eastern Europe, has concluded a long-term physical Power Purchase Agreement with Coca-Cola HBC Bulgaria EAD, one of the largest beverage producers in Bulgaria.

Knizhovnik Plant Adds Coca-Cola HBC Bulgaria as Its Second Corporate Offtaker

Under the agreement, announced on 8 October 2026, Enery will supply locally generated renewable electricity to the beverage company on an annual basis, delivered according to a fixed solar generation profile.

The contract is the second corporate PPA secured for Enery's Knizhovnik hybrid power plant. Enery presents this as evidence that large-scale renewable assets pairing solar generation with battery storage can meet the differing energy requirements of major industrial and commercial customers.

How the Hybrid Plant Combines Solar Generation with Battery Storage

The Knizhovnik hybrid power plant, situated near Haskovo in southern Bulgaria, pairs a 122 MWp photovoltaic installation with two battery energy storage systems rated at 70 MWh and 130 MWh. The facility produces roughly 200 GWh of renewable electricity each year, a volume matching the annual consumption of nearly 50,000 households.

Enery states that the battery storage component brings flexibility to the project, enabling renewable output to be managed with greater efficiency and contributing to the broader integration of solar power into Bulgaria's electricity grid.

A Multi-Offtaker Commercial Structure Behind a Single Asset

Severin Vartigov, Chief Commercial Officer at Enery, described the agreement as an illustration of the value long-term PPAs offer when they combine competitive energy sourcing with long-term predictability and measurable progress on decarbonization.

He noted that Coca-Cola HBC Bulgaria EAD has shown strong leadership in shrinking its operational footprint, and expressed pride that Enery can support that effort with locally produced renewable power.

Vartigov also pointed to what Enery considers the innovative commercial design at Knizhovnik. By placing utility-scale solar alongside battery energy storage systems and building multi-offtaker structures on top, the company says it can optimize portfolio generation, capture flexibility, and provide tailored, risk-managed energy solutions to a broad set of corporate partners. The presence of a second corporate PPA on the same asset shows this approach working in practice, with a single generation and storage portfolio supplying several large consumers.

Renewable Sourcing Tied to Net Zero by 2040

On the buyer's side, the PPA supports the wider commitment of the Coca-Cola HBC group to cut emissions across its operations and value chain and to reach net zero by 2040. By contracting renewable electricity through a long-term agreement, Coca-Cola HBC Bulgaria reinforces the connection between its energy procurement strategy and the construction of new renewable capacity in Bulgaria. Chavdar Chorbadzhiyski, Supply Chain Director at Coca-Cola HBC Bulgaria, said the group's NetZeroby2040 commitment demands action across every part of the business.

Securing renewable electricity from a local source, he explained, lowers the carbon footprint of the company's operations while backing the growth of Bulgaria's renewable energy sector. He called the partnership with Enery an important step in the company's decarbonization journey.

Enery's Portfolio, Pipeline, and Storage Business Across the Region

Enery positions itself as an independent power producer dedicated to reliable, affordable and long-term green energy solutions for its customers. Its diversified portfolio comprises 2 GW under construction and in operation, producing 1,095 GWh of clean electricity annually, sufficient to supply more than 1,002,121 households and avoid roughly 625,069 tonnes of CO₂ emissions per year.

Beyond generation, the company holds a project pipeline of nearly 10 GW spanning 10 countries in Central and Eastern Europe, a footprint it describes as placing it among the leading drivers of the regional energy transition.

Enery also works on optimizing revenue streams for utility-scale generation and storage assets and currently manages 8.5 GWh of third-party battery storage capacity. It supplies industrial customers with around-the-clock green energy and counts itself among the region's leading providers of corporate green PPAs.

Coca-Cola HBC Bulgaria's Three Decades of Operations in the Country

Coca-Cola HBC entered the Bulgarian market in 1992 and has grown into the country's largest beverage producer and one of its leading investors, with a workforce exceeding 1,000 people. The company runs two production facilities: a soft drinks plant in Kostinbrod, which marks its 30th year of operation this year, and a mineral water plant in Bankia, now in its 20th year of operation.

Guided by a vision to be the leading 24/7 beverage partner, Coca-Cola HBC Bulgaria maintains a broad portfolio spanning different occasions and consumer needs. Its products include some of the world's best-known beverage brands, Coca-Cola, Fanta, Sprite and Schweppes, alongside a growing range of premium spirits and coffee.

Matching Local Renewable Capacity with Industrial Demand

The agreement pairs a renewable developer holding a hybrid solar-and-storage asset in search of long-term offtake with one of Bulgaria's largest industrial electricity consumers looking for locally sourced renewable power to underpin its decarbonization targets.

Enery's statement frames the deal as proof that co-located solar and battery storage, layered with multiple corporate offtakers, can be structured around a range of industrial energy needs. For Coca-Cola HBC Bulgaria, the PPA links its electricity buying directly to new renewable capacity built in Bulgaria, in service of a stated group-wide goal of net zero emissions by 2040.
