Summary/Abstract

This paper develops a system dynamics model to analyze the impacts of different kinds of capacity payment as investment incentive mechanisms in Iranian electricity market. Since it is aimed that the incurred capital and operating costs of generation technologies be recovered in Iranian electricity pool, the noncompetitive capacity payment mechanism has been introduced for this purpose in order to encourage new investments in electric power generation system. In the current mechanism, the capacity payments are designated to the generating units in the whole country electricity market. An annual base value of capacity payment is proposed based on recovering the capital cost of a benchmark generation technology. This value is altered according to the operational reserve in the day-ahead electricity market. This supporting policy is simulated and analyzed in the proposed dynamic framework in order to track the trend of new investments in the Iranian electricity market. The feasibility study of implementing the regional capacity assignment is the main focus of this paper. Different possible regulating policies such as floating rates for capacity payment and electricity price cap, the multiple capacity payments to various technologies, and the regional electricity market with territorial capacity allocation are examined in order to investigate the consequences and performances of different decisions and policies in the capacity investment of Iranian electricity market.

Summary/Abstract

In South Korea, the incentive scheme for generators to add new power generation is based on the system marginal price (SMP) and the capacity payment (CP). The infra-marginal generators receive an extra margin due to the high SMP level and the new infra-marginal generators need to be built to achieve the optimal fuel mix. However, the Metropolitan zone needs more marginal generators due to the transmission congestion and environmental regulations, but the marginal generator in the Metropolitan zone does not have adequate profits for the new investment under the current CP. This paper suggests the appropriate investment incentive scheme for different zones. The introduction of forward capacity markets for different regions creates higher capacity market prices in the Metropolitan zone than those in the Southern zone. The introduction of forward capacity market also induces a new LNG generator investment in the Metropolitan zone while only new infra-marginal generators need to be added in the Southern zone.
