The Karatzis Group started to operate in the electricity generation sector in 2010 with the construction of photovoltaic parks in Katerini, Larissa, Viotia and Heraklion with a combined installed capacity of 18 MW. With a strong feeling of social responsibility and detecting the importance of environmental protection, the Karatzis Group had no alternative but to invest in renewable energy, one of the fastest growing business sectors in the Greek and international economy.
