  • analysis of specific bidding strategies in the wholesale market, as part of an investigation of alleged abuse;
  • analysis of regulatory conditions affecting renewable generation in different markets and forecasting of the likely evolution of the associated remuneration to identify most profitable target markets for investment in renewables;
