competition success review Published this article page no 92 The Power Generator shall supply RE Power complemented with Thermal Power in RTC manner keeping at least 80% availability on annual basis. o At least 51% of the annual energy supplied must correspond to RE Power and the balance should be drawn from thermal sources. RE power may include solar wind small hydro or a combination thereof with or without any Energy Storage System (ESS). A composite single tariff for renewable energy complemented with thermal energy shall be quoted by the bidders (e.g. DISCOMs). The RE component (including ESS component charged with RE sources) bought under this Scheme shall be eligible for Renewable Purchase Obligations (RPO) compliance. Benefits of the scheme DISCOMs will be able to meet their RPO. It is the obligation of certain power consumers e.g. DISCOMs to procure a fix percentage of their total consumption from the RE sources. o The National Tariff Policy (NTP) 2006 requires the State Electricity Regulatory Commissions (SERCs) to fix a minimum percentage of RPO based on each states varying renewable energy potentials. o The Electricity Act 2003 provides for the RPO to be decided by the SERC. DISCOMs will be able to purchase firm power at competitive rates to meet their deficits or replace costly power. DISCOMS will not have to undertake operations to integrate RE power into the grid since the responsibility of giving firm power will be with the Generator. DISCOMs may further save due to optimum scheduling of power among the sources wherein the generation and integration of power from renewable depends on the real time demand data. It is in line with the suggestions provided by expert group reviewing the Indian Electricity Grid Code (IEGC) which asserted that renewable energy power plants shall be treated as must run. o A must run status means that the concerned power plant has to supply electricity to the grid under all conditions competition success review buy.
