Our EnVision modelling framework, combined with our experience working closely with government and regulators, allows us to capture all major revenue streams, including:
- Wholesale market revenues – this includes the impacts on wholesale prices of increasing penetration from intermittent generation, interconnection, storage and demand-side response.
- Balancing market revenues – our modelling incorporates detailed half-hourly modelling of BM outcomes. Increasing imbalance volumes due to the rise in intermittent generation make the BM an increasingly important revenue source.
- Ancillary services – we model the requirements and provision for certain types of service in the long term, including the challenge of operating a system with large quantities of asynchronous generation.
- Embedded benefits and network charges – we capture these revenue streams in full detail, having provided Ofgem with the modelling to assess the wider system impacts of their proposed reforms.
- Capacity mechanism – we simulate the capacity auctions in full detail to project future auction outcomes. We provide the system security modelling used by National Grid to calculate the annual capacity requirement and the EFCs for intermittent and storage technologies.
Where appropriate, we use stochastic analysis to capture the full range of outcomes, including “tail-end” events which can drive a significant portion of value (or risk) for certain asset classes.
We assess projects under a wide range of market scenarios to highlight key drivers of opportunity and risk. These include uncertainties like decarbonisation and decentralisation of the capacity mix, policy changes, commodity price movements and revenue cannibalisation due to increasing market penetration.
Our analysis provided clear recommendations on the profitability of flexible generation assets under different scenarios and provided the basis for the client’s investment decisions.
