Installing the new renewable capacity has its due share of problems but integrating it with a nascent grid poses a much more formidable challenge.

Up against a staggering renewable energy target of 175 GW by 2022, India has its task cut out. Installing the new capacity has its due share of problems but integrating it with a nascent grid poses a much more formidable challenge. The country’s solar power generation capacity has gone up 32 times in a span of just six years, from 0.5 MW in 2011 to 16 GW now, but the transmission infrastructure is far from prepared to evacuate the kind of solar power being injected into the grid.

With the transmission system failing to keep pace with the increase in solar power generation, the glaring mismatch is bound to put immense pressure on the present transmission infrastructure, a situation which we can ill-afford bearing in mind the high stakes in the solar sector. We still have lessons to learn from India’s worst blackout of 2012, which plunged the entire North India into darkness for two days. Given the sporadic nature of electricity from clean energy sources like solar and wind, there is a need to ensure the transmission infrastructure is capable of handling the sudden surges in electricity during peak hours. With the evacuation system not yet ready, we are witnessing a situation where solar plants are being constrained to restrict generation, which is resulting in huge financial losses to developers.

Though the government has embarked on a $3.5-billion Green Energy Corridors (GEC) programme to overcome these challenges of power evacuation by strengthening the grid network, it is a daunting task which has to be taken up on a war footing to be able to deliver the desired results. The biggest challenge before us is to ensure that transmission systems are in place before the solar projects are ready. Considering that executing transmission projects takes up to five years as compared to 12-18 months for solar projects, we need to act urgently and decisively.

The GEC programme needs further push in order to ensure sufficient thrust from the industry in solar-rich states like Gujarat and Rajasthan. The mismatch between the number of demand centers and the available corridors is also a major concern. For instance, the 1,000-MW substation project at Kaythar in Tamil Nadu, which was scheduled to be commissioned earlier this year, has yet not seen the light of day for the simple reason that independent power producers are more inclined to evacuate the power to Gujarat and Maharashtra rather than the Northeast through the planned corridor. Distance can also be a major issue in India with six states in the western and southern parts accounting for 80% of the country’s installed solar capacity but only 38% of the power demand. The GEC programme is aimed at evacuating power from renewable energy-rich states to other states through 765 kV and 400 kV high-voltage transmission lines.

With storage facilities for solar energy lacking, how we manage the power generated at a specific point presents a stiff challenge. Maintaining grid stability can pose a major problem when a large amount of solar power is injected into the grid. Things can become even more difficult when the share of renewable energy in total power generation goes up in due course of time, but the constant flow of power is still lacking. The situation can, however, be overcome with modern technological breakthroughs and advancements like smart grids and solar energy storage solutions. Since many large solar facilities are in remote locations like deserts where grid infrastructure does not exist, we need to find a viable way to connect to and store solar energy, as and when needed. Bearing this in mind, the three-year action plan formulated by the Ministry of New and Renewable Energy has asked the Solar Energy Corporation of India to focus on storage solutions.

Though there has been considerable progress in coordinating generation and transmission at the state level to ensure sufficient in-state transmission, a lot more remains to be done. States should take it upon themselves to avoid delays in project execution by providing last-mile connectivity between inter-state and intra-state transmission lines, which is part of their responsibility. While the work at the national grid level is making some progress, the inadequate preparedness of states at the distribution grid level is a cause for concern.

Some of the states have even started asking wind and solar power developers to curtail generation in view of the insufficient transmission capacity. As a result, project developers are incurring revenue losses. To counter the situation, the Ministry of New and Renewable Energy has issued an advisory asking state power utilities not to direct renewable energy developers to reduce generation.

The inter-state transmission corridor being developed by Power Grid Corporation of India will help only if the transmission utilities in states supplement the effort by developing and strengthening their transmission infrastructure. Only then can we exploit the renewable energy potential of places like Ladakh and Jaisalmer and meet the growing power requirements of regions with high consumption. On the brighter side, states need not be worried about fulfilling their renewable purchase obligations, considering that the renewable energy costs are expected to decline once the inter-state sale of renewable energy picks up through the green energy corridor. Making the proposition even more viable, they have been exempted from paying the inter-state transmission system charges.

However, the efforts have to be doubled. There is a dire need to have a mechanism in place to ensure coordination between renewable energy generation and transmission at the state level so that there is sufficient in-state transmission. The scheduling and dispatch between states and regions must also be coordinated on priority. The government should come up with regulatory and policy guidelines which optimize cost-effective capacity expansion. In view of the intermittent nature of renewable energy, it is imperative to equip states with state-of-the-art renewable energy forecasting tools.

The Green Energy Corridor needs to be significantly widened so as to accommodate 50 more ultra-mega solar parks, in addition to the 34 under construction. While upgrading the transmission infrastructure to cater to the ever-growing needs of the future, the government should also not lose sight of the fact that the country’s per capita power consumption is projected to grow four times by 2030. These factors call for massive investments in the T&D segment for which private participation is a must. It is time for the policymakers to ensure the power sector is ready for the turnaround.

Chasing astiff 2022 target of 40 GW, India’s rooftop solar industry is finally coming into its own. Registering a phenomenal growth of 113 per cent over the past one year, the country’s rooftop solar capacity recently crossed the 1-GW mark, a milestone that should inspire the industry to give a much-needed impetus to this nascent segment and set the pace for unprecedented capacity additions in years to come. Rooftop solar in India has everything going for it—favorable government policies, streamlined processes, an efficient regulatory mechanism and an investor-friendly business environment. But will it be enough to take us to 40 GW? Not really!  Though leading solar consultancy services provider Bridge to India has projected an installed capacity of just 12.7 GW in 2021, a host of decisive measures can even propel us to the 40-GW mark.

While the commercial and industrial categories are driving much of the growth as of now, accounting for 63 per cent of the installed rooftop solar capacity, it is the hitherto dormant residential market that can really get things moving. The residential category has enormous potential that is simply waiting to be unleashed. Even if half of the estimated 205 million households in India opt for rooftop projects with an average capacity of just 2 KW, we can easily achieve an installed capacity of 20 GWand get halfway through in no time. Once solar systems become more viable, people will start viewing them as necessities. When that happens, there will be no looking back.

The government can act as a catalyst to spur the growth of the industry by coming up with an incentive-based mechanism and formulating effective policies. The rooftop solar segment will be in for a revolutionary change when it becomes mandatory for all residential buildings to install solar PV plants. More and more states should come forward and emulate the example of the Delhi government, which is providing a generation-based incentive or Rs 2 per unit (kWh) to residential consumers over and above the central government capital subsidy of 30 per cent. Easing the process, the Delhi government has also allowed people to call a third-party solar developer to get the solar PV plant installed.

A well thought out net metering policy can also make all the difference by enabling households to save on their electricity bill sand earn from the power they produce. Through net metering, residents can source their supply both from the grid and their solar PV plants. If the supply from one of them stops, the system switches to the other. The meter records power consumption from both the sources and charges the users for the difference. Reverse net metering is also an attractive proposition that enables consumers generating their own electricity through solar power to send the unused or excess electricity generated by their solar plants back to the grid and even get remunerated for it. This mechanism can be a game changer, but sadly, the implementation is lacking.

The major impediments in the way of growth of the residential rooftop category are the prohibitive costs of solar systems, lack of financing options, poor awareness levels and the practical difficulties associated with operation and maintenance, a factor which is dissuading many developers from opting for rooftop despite its immense scope.

While the cost of rooftop solar has been progressively declining at a rate of 12% per annum over the past four years, a typical1-KW solar system without battery costs Rs 65,000-70,000 with 30% subsidy. Since modules account for 60 per cent of the costs of a solar PV plant, the development of cheaper modules, coupled with optimisation of overall costs through competitiveness, economies of scale and integration of technologies, will make rooftop solar financially more attractive to residents. But a greater concern for house owners is lack of low-cost finance. Banks and financial institutions should extend low-interest loans to fund rooftop solar projects so that getting a loan for a solar PV plan becomes as simple as securing one for a car or house.

The lack of awareness also leaves a lot to be desired, explaining why the residential category continues to lag. We have observed during our solar awareness drives in residential areas that only a small fraction of people is aware how rooftop projects can help them save on their power bills and give assured returns. Some people are aware of the 30 per cent subsidy to domestic consumers, but then, they do not know how and where to apply. To bridge this gap, the Ministry of New and Renewable Energy has put in place a centralised facility to enable consumers of all categories, including residential, to apply online for installation of solar rooftops on their premises. Making the process hassle-free, the consumers will be directly approached by service providers.

The lack of skilled manpower for installation and operation and maintenance is another problem area. While the commercial and industrial categories are equipped with enough technical manpower to deal with snags, this is not the case in the residential category, where solution providers seldom have a provision for adequate back-up services. The situation calls for preparing a large technical workforce that is fully trained in the basics of installation, operation and maintenance. The move will also help generate thousands of new jobs. As an alternative for house owners who find the process of installation, operation and maintenance too cumbersome, companies like Hartek Power are planning to come up with portable 1-KW and 2-KW kits which will be as easy as installing a satellite dish.

Since 70% of India still resides in villages, rooftop solar can go a long way in electrifying rural areas as well as remote places which are not connected with the grid. Decentralised cluster power generation can work wonders in scantly populated far-flung villages, where the cost of supplying power through newly laid transmission lines can be prohibitively high. Empowering people by providing electricity to un-electrified areas, rooftop solar has done what the government could not. Lighting up the lives of people who have not known what electricity is, rooftop solar is poised to power a New India.
