We have years of experience drafting transaction documents and advising participants on the commercial, development and financing aspects of projects and domestic and cross-border transactions in the conventional and renewable energy sectors. We also have wide-reaching expertise in risk and compliance in these highly regulated industries.

Conventional Energy

We have been involved in most of the major transactions to have taken place in the conventional energy sector in Greece and our clients include oil and gas, electricity, water and mining companies, the government and State owned companies, private and institutional investors, financial advisers and developers. We have advised on landmark matters such as the privatisation of the Water and Sewerage Companies of Athens and Thessaloniki, the Public Power Corporation (PPC) and the Public Gas Corporation (DEPA), which opened the way for the privatisation of the Greek energy sector, and on the more recent groundbreaking tenders for the lease of hydrocarbons exploration and production rights. We have a cross-practice expertise in capital markets, financing and corporate deals in the energy industry. Our track record in structuring energy development projects as commercial transactions is substantial and we document a broad range of commercial agreements in this sector.

Energy & Infrastructure

Our practice has acted in pioneering energy projects, advising on the entire life cycle of transactions in this sector. We have an expertise in oil and gas, transport, electricity, water and mining financing, acquisition and development projects and clients include sponsors, lenders and the government.

Energy Regulation

Our practice is highly experienced in advising on compliance with the significant regulatory and legislative requirements governing activities in the energy sector. We monitor developments affecting our clients’ commercial activities and identify regulatory challenges and opportunities proactively. We are skilled in advising on licensing and permits, tariffs, trading, import and export and production in the gas and electricity fields. We have also been extensively involved in the liberalisation of the electricity and gas markets and the implementation of community legislation.

Renewable Energy

We are at the forefront of the renewables market in Greece, with a dynamic practice in advising on the tendering, developing and financing of wind, solar, hydroelectric, biofuel, biomass and geothermal projects, which is growing with the market.

Environmental Law

We take a pro-active approach to compliance in the environmental law sector which is increasingly affecting the way the majority of companies work. We endeavour to ensure that our clients are in a position to meet the complex and exacting requirements of the regulators. Our practice is well placed to advise on the environmental risks and liabilities arising in the context of mergers, acquisitions, projects and privatisations. We conduct environmental impact assessments, undertake project categorisation and advise on the process for obtaining permits and licences. If disaster strikes, we represent our clients in litigation arising from environmental contamination and compliance failures.
