A 15-year hybrid PPA between Enery and Teva Pharmaceutical Industries marks a historic step for the energy transition: it is the first agreement of its kind in Central and Eastern Europe to include a battery energy storage system.
Enery has secured another major success in the renewable energy sector across Central and Eastern Europe. The company has signed a 15-year hybrid power purchase agreement with Teva Pharmaceutical Industries, one of the world’s leading producers of generic and specialty medicines. In Bulgaria, this contract covers not only the supply of green electricity but also the integration of battery storage.
In practical terms, this secures security of supply and sustainability now go hand in hand. The PPA guarantees Teva 60,000 MWh of clean electricity per year and supports the decarbonization strategy of the company’s Bulgarian sites.
A Strong Partner
Teva supplies millions of patients worldwide with a broad product portfolio, but pharmaceutical production is highly energy-intensive. Accordingly the company has set ambitious climate targets: a 46.2 percent reduction in Scope 1 and Scope 2 emissions by 2030 and a full switch to renewable energy in Europe by 2035.
For Enery, the partnership is therefore strategically significant as well as commercially attractive. Chief Commercial Officer Severin Vartigov emphasizes that these projects are made possible through collaboration with market leaders such as Teva—companies that demonstrate a strong commitment to both society and the environment. Teva, for its part, sees the agreement as an important step in its decarbonization journey: it secures clean energy while also strengthening grid stability and flexibility.
For the off-taker, this PPA model offers a concrete way to reduce its carbon footprint through an instrument that extends beyond individual sites. At the same time, it provides stable terms and a predictable energy supply over a 15-year period—further evidence of how industrial companies are beginning to shape the energy transition more actively with Enery’s support.

Knizhovnik Solar Park with BESS
At the heart of the agreement lies the Knizhovnik solar park near Haskovo in southern Bulgaria, with a generation capacity of 122 MWp. The park is expected to produce around 200 GWh of electricity per year—enough to supply almost 50,000 households. The solar installation is complemented by two battery systems, one with 70 MWh and the other with 130 MWh of capacity.
As a result, the hybrid system can respond flexibly to grid requirements, smooth peak loads, and stabilize grid feed-in. For Enery, this is already the fifteenth PPA signed in the past four years, underlining the growing importance of stable partnerships across the region. Hybrid PPAs that combine solar generation with battery storage are still rare, which is precisely what makes this agreement so innovative.
By integrating storage technology, the contract expands the traditional model of pure solar power supply and raises grid stability to a new level. It creates a degree of flexibility that benefits both plant operators and off-takers. A deal of this size and duration remains unusual in Bulgaria, but it shows that market participants are increasingly willing to commit to renewable energy over the long term. Agreements like this create planning security for energy producers and industrial companies alike.
