Biomass-based power project developers have been facing challenges such as increasing raw material costs, low tariffs, inadequate power evacuation infrastructure etc. While the developers have sought tariff revisions, the issues related to evacuation facilities has not been on the priority list of state governments.

Bihar has an estimated renewable energy potential of 12 GW to 18 GW. To harness this potential , the state government announced the Bihar Policy for Promotion of New and Renewable Energy Sources, 2011 in June 2011, which will remain in effect till June 2016.

Grid-connected concentrating solar power (CSP) plants face the operational limitation of not being functional at night. In addition, unpredictable weather conditions and intermittent sunlight availability impact such projects' generation output and, therefore, their cost effectiveness. In this context, the installation of grid-scale storage solutions at CSP plants becomes important to ensure that electricity supply is not impacted by variations in sunlight availability and the plant is able to supply power throughout the day based on grid demand as well as meet base load requirements.

The renewable energy certificate (REC) market, after being in operation for only over a year, has already come a long way. Its market value, that is, the total value of REC's cleared, peaked at Rs 632 million in February 2012, compared to a mere Rs 585,000 in March 2011 when the first RECs were traded in India.

Before the launch of the Jawaharlal Nehru National Solar Mission (JNNSM) in 2010, not much attention was paid to solar radiation assessment in India. The country had 45 meteorological stations managed by the Indian Meteorological Department to operate as weather observatories, which were not equipped to collect data on direct normal irradiance (DNI), a measure of solar radiation received per unit area, along with weather parameters at various locations.
