Areas of involvement and expertise

Expertise in the areas of renewable energy, electricity storage, market and grid integration of distributed energy resources, transmission and distribution networks, autonomous island systems and interconnections, smart grids and electromobility. Engagement in more than 120 research and consulting projects.

Exposure to diverse international technical and regulatory environments through collaboration with DSOs, TSOs and utilities around the world (TEPCO, KEPCO, SGCC, Enedis/EDF, TERNA, Enel, LADWP/Edison California etc.).

Specific areas of involvement and expertise:

· Regulation, grid integration and market participation for renewable energy, electricity storage and distributed energy resources: legal and regulatory framework for planning, licensing, grid access and market participation of renewables and storage, collocated & hybrid RES-storage stations, integration of behind-the-meter storage in prosumer facilities.

· State aid schemes in Energy: advisory support for the design, EC notification & approval and transposition in national legal & regulatory framework of State aid schemes in the areas of renewable energy, storage and network infrastructure, experience with open/competitive schemes and individual support measures, PCI projects.

· Energy planning: long-term planning for generation & storage systems to support decarbonization targets, resource adequacy analysis, market analysis. Support to development of National Energy & Climate Plan.

· Regulatory aspects of electricity networks: network codes, connection and use-of-system tariffs, integration of distributed energy resources, hosting capacity analysis, congestion management etc.

· RES projects (on/offshore wind, PV, solar thermal, hydro): feasibility analysis, sizing and technical design, licensing, grid interconnection, State aid auctions, market participation, PPAs, specialized technical studies (RfG compliance, power quality, short circuit analysis etc.).

· Energy storage projects (merchant storage, colocation with RES & integration in hybrid RES-storage entities, deployment in prosumers): licensing, technical design, grid access, CBA studies, investment feasibility analysis, market participation, support schemes, Experience with pumped hydro, batteries and thermal energy storage solutions.
