Electricity, Renewables and Energy Transition

When it comes to the evolving energy sector, our law firm is leading the way

The energy market has seen considerable change over the past decade and will continue to evolve even more as we transition from traditional energy sources such as coal and gas fired generators, through to greener sources of energy. The market and underlying technology to support the transition is rapidly advancing – requiring a legal services partner with technical excellence, detailed industry knowledge, and regulatory reform expertise.

Our law firm’s experience in energy covers a range of asset classes, from conventional power (coal and gas fired) through to traditional core renewables (wind, solar, hydropower) and new energy technology (batteries, microgrids, hydrogen, waste to energy, carbon capture). We are here to support you through the entire life cycle of electricity, renewable energy and the technology paving the way for the new energy future.
