Supporting future power capacity needs, today

With a population of more than 1.3 billion people, India is one of the world’s fastest-growing economies. The government has set an ambitious goal of securing 450 GW of clean, affordable and sustainable power for its citizens, and India has made great strides—having already built 87 GW of additional renewable power capability*.


“In India, we are going to increase the share of non-fossil fuel, and by 2022 we plan to increase our renewable energy capacity to much beyond 175 GW, and later till 450 GW”.

— Prime Minister Narendra Modi

Providing energy security for India

To support the country’s continued growth in renewable power, the Ministry of Renewable Energy (MNRE), the Ministry of Power and Solar Electricity Corporation of India (SECI) have proposed solutions for round-the-clock power (RTC), firm and flexible power and peaking power. Gas turbine technology can provide energy security through the production of reliable, flexible and sustainable energy that supports and complements renewable energy sources. This is known as “grid firming”.


Bridging India’s renewable energy gap

Grid firming or grid balancing (also known as capacity firming or renewable firming) is the addition of another energy resource to a renewable power plant to provide secure, stable power any time the sun isn’t shining or the wind isn’t blowing. Grid firming is vital for any power generation network, especially one like India’s, with a high percentage of renewable power sources.


These charts represent a typical day in India. The “duck curves” show the impact of higher renewable penetration on net load demand. When more solar production is available on the grid during the day , the “belly” of the duck curve gets deeper. When the sun goes down, however, flexible resources like aeroderivative gas turbines are necessary to compensate for the sudden drop in solar power and effectively manage the grid. As renewable sources start to grow on the grid, the curve steepens to show how ramp rates become essential to maintain a stable grid.

Gas power is now a suitable solution for India

Any region generating renewable power needs a continuously available energy solution to support it. There are many technologies capable of supporting grid firming, including —but not limited to—gas-fired power plants, coal-fired power plants and energy storage. However, one fuel source offers a solution for India that’s cleaner, more efficient and flexible: Natural gas.


NEW! The key to India's energy future

India’s electricity demand is growing. With its ambitious renewables targets, the national grid needs support from diverse sources to help ensure round-the-clock supply of reliable and flexible electricity that is not interrupted. Find out more about the role of gas and renewables to address the country's growth and reduce carbon emissions, while embracing a “gas-based” economy in GE's position paper.



Position paper: Gas supply in India

Gas hasn’t always been the most affordable option, but in India today—and for the foreseeable future—gas prices have dropped to a competitive level. It’s also highly available throughout the country, and can work well with India’s unique interconnected grid, in both standalone and hybrid configurations. Because gas can be dispatched from anywhere within India’s four grid regions, it also has a distinct advantage over energy storage, which needs to be attached to each solar plant.

Gas plays a vital role in meeting India’s renewable energy goals

India’s goal of reaching 220 GW of renewable energy generation by 2022—and ultimately 450 GW—requires a plan to implement a mix of grid firming solutions to manage the intermittent and variable nature of renewable energy.

Gas-based thermal power has inherent flexible characteristics that makes it ideal for grid firming. Gas power can also achieve single-digit NOx emissions, 50% lower CO2 emissions as compared to coal, and doesn’t produce any ash or sulphur. With India’s mature gas pipeline, it can be deployed just about anywhere in the country to provide quick, efficient power to help support India’s growing energy needs.

The shorter the start-up time, the quicker a turbine can achieve minimum load and support additional power needs. Gas units take the least time required for start-up and consume less energy per MW, making them well suited for supporting the variable nature of renewable power. In fact, some gas turbines can reach full plant load in less than 15 minutes. This flexibility allows grid operators to quickly dispatch gas power when needed and shut down or schedule for minimum load when renewable power is in abundance.


Higher ramp rates allow the plant operator to adjust net power more rapidly to meet changing demand caused by the variability of solar and wind power. Gas turbines ramp the fastest of all energy generation solutions--up to 88 MW in a minute.


High part load efficiency, a low minimum load, and deeper turndown all contribute to the flexibility of aeroderivative (aero) gas turbines. Aeros are also hydrogen-capable and can operate on a wide variety of fuels, like natural gas, diesel and aviation fuel—but can also be configured to operate on fuels such as naphtha, LPG, ethane, ethanol, bio-diesel and others.


Get up and running with power when you need it. GE’s trailer-mounted TM2500 can be installed in less than three months, and our other aero gas turbines can be up and running in six months, helping you get the dispatchable power you need.


GE’s gas turbines can provide very high part-load efficiencies compared to other thermal assets, which results in significant economic benefits when turning down the load.
