Sustainability is not a separate pillar of our operation, but it is embedded in how the company grows, operates and creates value. Our 2025 Sustainability Statement reflects a year of steady progress, where environmental performance, social impact and governance maturity evolved together to support Greece’s transition to a cleaner and more resilient energy system.
Building on the foundations set in the previous year, the 2025 report demonstrates how sustainability is becoming increasingly integrated into decision-making, operations and long-term strategy.

Principia's Chief Financial Officer, George Koukoumelis, said:“Principia’s new Sustainability Statement demonstrates our strategy to support the energy transition, achieving high efficiency and continuing to embed sustainability at the core of our activities. With a targeted approach to development, crucial investments in new technologies, such as battery energy storage systems, as well as continuous moves to manage our environmental footprint, we are strengthening the creation of long-term value, both for our company and for society as a whole.”
Here are our significant performances in Environmental, Social and Corporate Governance issues.
Our core contribution to sustainability remains the production of clean energy. In 2025, electricity production exceeded 1,100 GWh, with 66 renewable energy plants and a total capacity of 577 MW. At the same time, the energy portfolio continued to evolve strategically. Investments in Battery Energy Storage Systems (BESS) and the electrification of the Perasma Solar Cluster in Kozani enhanced system flexibility and grid resilience, while the acquisition of 150 MW of wind assets further strengthened the company’s footprint in renewable energy.
Sustainability is fully integrated into our management structures, overseeing ESG priorities and performance, while regular reporting and internal controls ensure accountability. At the same time, we maintain a strong ethical framework. In 2025, zero incidents of corruption or bribery were recorded, supported by policies, training and monitoring systems that promote transparency and responsible business conduct. This structured governance approach enables us to translate sustainability commitments into measurable outcomes, aligning strategy with long-term value creation.
In 2025, our workforce grew to 138 employees, reflecting both organizational expansion and investment in talent. A strong emphasis was placed on development, with 10,560 hours of training delivered, supporting both technical expertise and broader ESG awareness. At the same time, we maintained a workplace culture grounded in safety, inclusion and integrity, achieving zero incidents of discrimination, fines or penalties during the year.
As part of our social contribution, we implemented and supported initiatives with a substantial impact on local communities and the young generation. Among them, we supported the creation of a new Artificial Kidney Unit at the General Hospital of Karystos and the Youth Basketball Final Four in Kozani. At the same time, we proceeded with academic collaborations with Universities and Polytechnic Schools throughout Greece, continued the educational program for youth "Energy on the Go", organized book donations and strengthened the culture of giving through our Corporate Volunteering Program.
We recorded GHG emissions intensity of 78.2 tCO₂e/€m (location-based) and 75.4 tCO₂e/€m (market-based), demonstrating a consistent focus on monitoring and managing emissions across operations. At the same time, we reinforced our circular economy approach by achieving 100% recycling of hazardous waste. We have established a net-zero transition plan targeting 2040, with intermediate milestones and structured actions covering energy sourcing, efficiency and electrification.
Our Sustainability Statement for 2025 not only captures performance, but also how we evolve. We continue with the same goal: to produce clean energy, operate responsibly and create value for society, the environment and future generations.

Our first Sustainability Statement outlines our strategic approach to Environmental, Social and Corporate Governance issues, for a greener future
2024 was a milestone for Principia. We published our first Sustainability Statement, which is fully aligned with the European Sustainability Reporting Standards (ESRS), and highlights our strategic approach to Environmental, Social and Corporate Governance issues. We are proud to clearly and transparently demonstrate our commitment to progress, innovation and responsible development.
Watch the video:
Principia's CEO, Aristotelis Chantavas, said: "Sustainability for Principia is not a trend – it's a commitment. Our first Sustainability Statement clearly captures our ambition: to lead the energy transition with responsibility, innovation and a real impact on people's lives. We are here to create value – for society, the environment and future generations."
Here are our significant performances in Environmental, Social and Corporate Governance issues.
The heart of our activity is the production of clean energy, with 66 RES projects and a total capacity of 577 MW. In 2024, more than 1,133 GWh of electricity was produced, capable of meeting the needs of hundreds of thousands of households. At the same time, we completed the construction of the Perasma Solar Cluster with a total capacity of 95 MW in Western Macedonia and started the development of our first energy storage project (BESS), in Chalkidiki.
Our energy efficiency is constantly improving:
Our commitment to net-zero operation by 2040 is based on a targeted reduction of greenhouse gas emissions, as well as the integration of Scope 3 emissions. At the same time, we implement biodiversity protection actions in all our projects, while the construction and operation of our parks are harmonized with rigorous environmental studies. It is noteworthy that no pollutants were recorded in 2024 on land, water or air - a clear indication of our responsible and sustainable operation.
Principia is its people. Our workforce consists of 137 employees in Athens, Alexandroupolis, Patras, Evia and Kozani. We emphasize safety, diversity, equality and lifelong learning.
Health & Safety
In 2024 we achieved zero accidents, exceeding 400,000 incident-free man-hours. Our distinction as a Health & Safety WINNER at the Health & Safety Awards 2024 confirms our commitment to a completely safe working environment.
Human Resources & Education
Work-Life Balance
Social Contribution
Principia always works in collaboration with local communities. In 2024 we implemented 36 social initiatives supporting the work of 21 organizations and NGOs. Indicative actions include:
"Be The Hero", our company's multi-award-winning corporate volunteering program, is a living example of social contribution in practice. In 2024, 10 activities were carried out, with the participation of 80% of employees and more than 1,030 hours of volunteering.
The 2024 Sustainability Statement marks Principia's transition to a more mature and transparent operating model. We have established 8 Management Committees, which oversee sustainability issues, while the annual Sustainability Plan is approved by the management team.
ESG in practice
Transparency & Compliance
Principia's 2024 Sustainability Statement is not just a record of numbers. It is proof that development can and must go hand in hand with responsibility, transparency and care for people and the environment. We envision a future in which energy, society and nature go together, with leadership that serves this purpose.

We completed the innovative program Vamvakies Social Green Project that empowered enterpreneurship and created value for the residents of Kozani and the wider region.
The Vamvakies Social Green Project was developed by Principia, in collaboration with Wise Greece and CluBE under the auspices of the Municipality of Kozani, exclusively for the Prefecture of Kozani and the wider region, with the aim of supporting people who are interested in empowerment, entrepreneurship and careers in the food industry.
The program was divided into 2 sub-projects: the empowerment of a small group of women farming in the Vamvakies PV plant area and the provision of free educational seminars on various topics for all the residents of Kozani.
The idea was put into practice at the solar plant near Polymylos Kozani, where a small group of women cultivated herbs, both in the open spaces and under the panels.
At the same time, the women were supported by a team of advisors and trainers, with the aim of becoming micro-entrepreneurs, marketing these original products and earning a substantial income.
From the materials of the crops in Vamvakies, we created the MYROLAND series of products, which consists of the following: spices for chicken, spices for pork, a Mediterranean mixture of herbs, as well as herbal drinks with the flavor of melomakarono, tsoureki, banoffee and paliouri.
This is the first time in Europe that a series of products from the land of a solar park has been launched on the market.
Educational programs were organized and made available to all Kozani residents in order to promote and enhance entrepreneurship. The seminars took place online once a month and were supported by a large team of experienced trainers who flank the participants in every stage of their business career.
The participants were able to develop their knowledge of the nutrition sector and connect with mentors who could help them in every professional step. They also received training in very important entrepreneurship issues such as the preparation of a business plan, the production and promotion of products, effective communication, developing a network of customers and partners, digital marketing and much more.
The Vamvakies Social Green Project was honored for its Innovation and Social Impact with the Bravo Sustainability Award in the Society and Partnerships category and with the Gold Hellenic Responsible Business Award in the Decent Work & Economic Growth category.
Our Creating Shared Value (CSV) initiatives are fully in line with the 17 UN Sustainable Development Goals. The Vamvakies Social Green Project is aligned with Goal 4 (Quality Education), Goal 5 (Gender Equality) and Goal 8 (Decent Work & Economic Growth).

With our crucial contribution and after 5 years of procedures, the European Commission registers Greek flower honey "Kissouri Honey" as a Protected Designation of Origin (PDO).
Our decisive contribution to the local community of South Evia was recently recognized with the registration of the Protected Designation of Origin (PDO) for "Kissouri Honey" by the European Commission.
The project "Support of the Karystos Beekeeping Association for the registration of the name 'Kissouri Honey' in the Community Register of Protected Geographical Indications", was commissioned and funded by the company in January 2019. It concerned the Association, which is the only body that has the right to submit the relevant registration request. Five years later, the competent EU body certifies Kissouri honey as a Protected Designation of Origin. The honey is produced in the wider area of Kafireas, our largest wind farm in Greece.

"We are proud that the product is registered with a Protected Designation of Origin. Our company has been active in the region of South Evia with targeted social actions since 2017, seeking to empower the local communities. The registration of PDO in "Kissouri Honey" is for us the real fruit of our efforts in the region. We see this achievement as an opportunity for the recovery of local honey production, but also a real support to the families that depend on it."
— Eugenia Melea, Chief People, Culture & Sustainability Officer at Principia
The "Kissouri" honey is the autumn heather honey produced in the region of Karystia by bees that harvest the flowers of the purple heather (Erica manipuliflora) that grows in the area. It is presented in liquid or crystallized form, its taste is slightly bitter, its color is dark with red-bronze shades, and its aroma is intense and long-lasting.
The PDO name not only proves the origin of the product, but also sets it apart from the competition, highlighting its unique quality and providing consumers with certainty of its authenticity. With the product being legally and financially protected, local producers have the opportunity to further develop their business activity through beekeeping.
Our support towards this effort confirms our commitment to initiatives for the sustainable development of local communities, in all regions of Greece where we operate. Our initiatives are fully aligned with the 17 UN Sustainable Development Goals, with this activity being part of SDG 8: Decent Work and Economic Growth.
