ROAM's Long-Term Integrated Resource Planner (LTIRP) has been used to co-optimise the development of generation and transmission. ROAM was engaged by the AEMC to analyse the impact of optional financial firm access on the development of the NEM. ROAM's modelling suite is able to plan the long-term development of inter-regional and intra-regional transmission, and test these developments in detailed time-sequential dispatch modelling.
ROAM has also assisted clients such as Powerlink and Electranet in conducting RIT-T tests (Regulatory Investment Test for Transmission) on specific transmission augmentations. For this task, ROAM uses a range of tools including our Thermal Constraint Development Tool (TCDT). With this tool, which is used by the market operator (AEMO), ROAM is able to formulate custom transmission constraint equations reflecting the capabilities of the transmission augmentation of interest. These fit seamlessly into ROAM's dispatch forecasting engine 2-4-C® to assess the impact of the augmentations on the market. ROAM has also assisted TNSPs is assessing the competition benefits of transmission augmentation using our model's dynamic bidding capability.
For Transmission Network Service Providers (TNSPs) ROAM provides expert advice on the interpretation and application of rules and regulations, and detailed analysis of the market to help formulate future investment and areas of potential growth to support TNSP's revenue proposals to the regulator (the AER). The future generation development pattern in the NEM is unknown and hence it is necessary to assess the need for network developments against a wide range of plausible futures.
ROAM has also assisted market participants in assessing the impact of the transmission network on generation assets. In particular, ROAM uses dispatch modelling to conduct congestion assessments which incorporate the likely development of generation and transmission. For this purpose, ROAM is able to apply the TCDT to model constraints which are not otherwise available. ROAM has assisted numerous clients in assessing:
- The potential for congestion to impact the revenues of new entrant generation;
- The impact of generation or transmission development on existing assets;
- The potential for a generator to benefit from a transmission augmentation or the implementation of a run-back scheme.
