Looking Ahead

The volumes traded in the short-term market in the last five years have remained more or less at about 12% of the total generation. However, with robust transmission, better liquidity on supply side and growth in demand, the short-term power market should be able to achieve a much higher growth in the near term. In so far the existing markets are concerned going forward our endeavor would be to:

  1. Promote SMART procurement and optimize power purchase cost for distribution companies with introduction of new IT tools.
  2. Integrate greater number of renewable energy generators in exchange platform and facilitate them to sell their green power through Green Term Ahead Market (G-TAM).
  3. Introduce new bid types in day-ahead and term-ahead markets to help both buyers and sellers to participate in the Exchange more efficiently.
  4. Pursue policy advocacy on deepening of power market.
