“…It is much lower than a measure of 0.18 considered as highly concentrated by the US Horizontal Merger Guidelines. HHI of India's electricity generation market is also lower than that of England and Wales, where the HHI is 0.16 and is also lower than that of Sweden, where the HHI is 0.32 (Chang, 2007). The HHI measure for the national market suggests that there is no concentration of generation capacity in the Indian electricity market.…”

“…As electricity has features of highly variable price-inelastic demand, considerable short-run capacity constraints, and very costly storage, firms with very small market shares may also have significant market power (Borenstein et al, 1999(Borenstein et al, , 2002. Chang (2007), in measuring competition and market power, has used five measures; Concentration Ratio, Herfindahl-Hirschman index (HHI), Supply Margin Assessment (SMA), Residual Supply Index (RSI) and the price-cost mark-up. An ideal index of market power is one that provides in a simple number a measure of the ability to exercise market power.…”

“…A standard measure of the market concentration is the Herfindahl-Hirschman Index (HHI), shown in Eq. (2), that receives 1 as the maximum value, corresponding to monopolistic markets and approaches zero for competitive markets (Chang 2007).…”

The Treaty establishing the Energy Community in Southeastern (S.E.) Europe (2005), aims to facilitate the creation of a common, competitive energy market in the region. However, the signatory countries have not advanced in the same pace, to implement this undertaking. This paper ranks the nine Energy Community countries, according to their prospects for integration into a regional competitive wholesale gas market, using a Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The method evaluates the state of technical and institutional framework and the actual functionality of their markets. Sensitivity analysis is used to examine the robustness of the final results.

“…For example, the LI in the Singapore market was about 0.188 in year 2005. The LI in the British electricity spot market was 0.124 during January 1992-March 1993, 0.259 during April 1993-March 1994, and 0.208 after March 1994 [30]. Having knowledge about the LI from the experimental data, the experience factors k, and δ can be regulated to represent impacts of MSH and DR in LI.…”

With introducing demand response provider (DRP) in smart grid paradigm, small consumers can actively participate in various demand response programs, especially price-based programs. This newly important matter can significantly affect the power system problems, such as expansion planning. Accordingly, consideration of small consumers via DRP in longterm market equilibrium can be notably useful. This paper proposes a bi-level game framework with iterating between master and slave level to find the long-term market equilibrium in the pool-based market, including opponent generation companies (GenCos), DRP, and independent system operator (ISO). In the master level, a set of investment decisions are generated. Then, the system information is updated and the market is cleared in the slave level. After evaluating all decision-making options, the ISO selects the best option based on a tradeoff analysis. The proposed method is examined on a system with one DRP and two GenCos under ISOs supervision.Index Terms-Advanced metering infrastructure (AMI), demand response provider (DRP), expansion planning, game theory, long-term market equilibrium, smart grid, supply function equilibrium (SFE). Parameters ALNumber of expansion option.
