In the BLUE Map Scenario, these investment needs increase to USD 4.0 trillion. The addition of almost 50% in the BLUE Map Scenario may initially appear huge. Comparing the investment needs for the power sector, however, with India's cumulative gross domestic product (PPP based in 2008 prices) of USD 855 trillion between 2010 and 2050, the total investment needs related to power generation in the Baseline and BLUE Map scenario represent only a range of 0.3 to 0.5% of total cumulative GDP.
