Market Value of Electricity - The principle for calculating the market value of electricity supplied by the State Electricity Board should be based on the market value of electricity itself, rather than the rate charged to suppliers. The tribunal correctly compared the power's market value with the open market rate, rather than the supplier rate, to determine the correct valuation ["INDKAR00000287058"].
Land Valuation for Transmission Lines - When high tension transmission lines are drawn across land, the land's utility is affected, leading to a diminution in its market value. The market value of land within the corridor is often determined at Rs. 2,00,000/- per acre, based on evidence such as certificates from the Sub Registrar ["2025 Supreme(Online)(Kar) 442476"], ["2025 Supreme(Online)(Kar) 35987"], ["2025 Supreme(Online)(Kar) 36102"], ["2025 Supreme(Online)(Kar) 36047"], ["2025 Supreme(Online)(Kar) 36112"], ["2025 Supreme(Online)(Kar) 442436"], ["2025 Supreme(Online)(Kar) 36168"], ["2025 Supreme(Online)(Kar) 442399"].
Diminution in Land Value - Courts typically award 50% of the market value as diminution for land affected by transmission lines; however, this percentage can be modified based on case specifics. For example, some judgments reduce this to 30% after re-evaluation, citing the absence of detailed quantification of utility loss or restrictions ["2025 Supreme(Online)(Kar) 35987"], ["2025 Supreme(Online)(Kar) 36168"], ["2025 Supreme(Online)(Kar) 442399"], ["2025 Supreme(Online)(Kar) 36122"], ["2025 Supreme(Online)(Kar) 442493"].
Valuation Methodology - The valuation considers factors like the location of the land, the extent of the line, and the impact of the corridor. The market value is often fixed based on certificates, schedule rates, or guideline values, but these may not always reflect the true market value. Courts emphasize that the fair value fixed by the government is merely a guiding factor, and actual market value should be determined based on evidence and relevant parameters ["INDKAR00000444048"], ["2026 Supreme(Online)(Ker) 953"], ["2026 Supreme(Online)(Ker) 955"], ["2025 Supreme(Online)(Ker) 57435"], ["2026 Supreme(Online)(Ker) 954"].
Compensation for Trees and Structures - Compensation for trees cut or structures affected is calculated separately, often based on schedule rates or the value of trees, with some judgments applying a 30% increase over the base rates for structures, depending on the year of valuation ["2026 Supreme(Online)(HP) 75"], ["2026 Supreme(Online)(Ker) 953"].
Calculation of Market Value - The calculation of market value involves considering the present rates, location-specific factors, and the extent of impact. For structures, the rates are adjusted based on the year of notification, with courts applying relevant schedule rates and guidelines to arrive at fair compensation ["2026 Supreme(Online)(HP) 75"], ["2023 0 Supreme(Guj) 286"].
Analysis and Conclusion:The valuation of land affected by high voltage transmission lines primarily hinges on its market value, which is determined through evidence like certificates, schedule rates, and local parameters. The impact of the corridor reduces land utility, leading courts to award a percentage of the market value as diminution—commonly around 30-50%. For electricity, the market value should be based on the prevailing market rates of power, not the supplier rates, ensuring a fair valuation aligned with open market conditions. The methodology emphasizes evidence-based valuation, taking into account location, extent of impact, and relevant guidelines, to arrive at just compensation ["2023 0 Supreme(SC) 1201"] ["2025 Supreme(Online)(Kar) 442476"] ["2025 Supreme(Online)(Kar) 35987"] ["2025 Supreme(Online)(Kar) 36102"] ["2025 Supreme(Online)(Kar) 36047"] ["2025 Supreme(Online)(Kar) 36112"] ["2025 Supreme(Online)(Kar) 442436"] ["2025 Supreme(Online)(Kar) 36168"] ["2025 Supreme(Online)(Kar) 442399"] ["INDKAR00000444048"] ["2026 Supreme(Online)(Ker) 953"] ["2026 Supreme(Online)(Ker) 955"] ["2025 Supreme(Online)(Ker) 57435"] ["2026 Supreme(Online)(Ker) 954"].
