Renewable energy has seen significant growth over the past two years. Around 6.9 GW of capacity was installed during 2015-16. In 2016-17, about 3.1 GW of capacity has already been installed,  which accounts for 59 per cent of the total power capacity addition in the country.

The renewable energy sector’s performance over the past year has been encouraging. In the beginning of 2016, the government declared the revised National Tariff Policy, 2016, which laid out several provisions for the growth of the sector, such as the continuation of the renewable purchase obligation (RPO) trajectory for obligated entities and an enabling framework for interstate wheeling of renewable power. In addition, the need to promote waste-to-energy power plants was also highlighted. Apart from the development of the utility-scale solar power segment, the industry is also focusing on the development and deployment of decentralised rooftop photovoltaic (PV) installations.

The year has been extremely positive, particularly for the renewable energy sector. The solar segment has been growing strongly, at more than 100 per cent per annum, aided by favourable government policies, a sharp reduction in costs, and environmental benefits. Other segments including wind, small hydro and biomass have also been growing at a steady pace. The sector is maturing with the successful closure of secondary transactions, notably, the Tata Power-Welspun and Greenko-SunEdison deals, and the launch of debt capital market offerings by many players.

 

What have been the key highs and lows in the renewable energy sector during the past year?

Anish De

The key highs were as follows:

  • A solar tariff of Rs 4.34 per kWh was recorded in January 2016. The solar power prices discovered later have consistently been in a similar tariff range.
  • Signs of consolidation were seen in the sector with big transactions taking place in 2016, including Tata Power’s acquisition of Welspun’s renewable energy assets, and SunEdison’s sale of 450 MW of its renewable energy assets to Greenko.
  • The state electricity regulatory commissions (SERCs) have been taking initiatives to promote renewable energy. Meanwhile, RPO targets have been increased to 17 per cent by 2018-19 with the non-solar RPO target being 10.25 per cent and the solar RPO target being 6.75 per cent.
  • The financing scenario has improved significantly, with commercial banks offering longer loan tenors and competitive interest rates. Financial institutions such as YES Bank, the Export-Import Bank of India, the Indian Renewable Energy Development Agency, IDBI Bank and Axis Bank successfully raised capital through the innovative green bonds route. Large players such as CLP India, Hero Future Energies and ReNew Power also raised low-cost capital in the domestic market, totalling Rs 14 billion.
  • The need for innovation to better integrate renewable energy is being recognised. The Solar Energy Corporation of India (SECI) is now inviting/planning tenders for solar-wind hybrids, integrating storage with solar, etc.
  • The National Tariff Policy issued in 2016 waived interstate transmission losses and charges, creating a compelling window for states deficient in renewable energy resources to competitively procure from renewable-rich states.
  • The off-grid segment received a fresh impetus with the National Tariff Policy seeking to address the key risk of grid arrival perceived by micro/minigrid investors by creating exit options.

The key lows were as follows:

  • While there is both unserved and underserved demand in most states, this is not fully reflected in the system, resulting in apparent surplus situations. This has raised concerns on the willingness of states to contract additional power.
  • States like Karnataka and Jharkhand faced significant delays in the signing of power purchase agreements (PPAs) by the discoms.
  • Grid curtailment-related issues were witnessed in Tamil Nadu due to a large quantum of wind penetration into the system. Similar instances have been observed in Rajasthan for solar projects.
  • RPO non-compliance still remains a major hurdle despite a push from the central government.

While there has been a lot of positive sentiment about renewable energy, the projects are not being developed at the desired pace. The Ministry of New and Renewable Energy (MNRE) had planned about 16.6 GW of capacity addition for 2016-17. However, only 3.2 GW has been added as of September 2016 (less than 25 per cent of the target). Of late, the focus has been more on solar. Other segments like wind, biomass and small hydro are not getting adequate attention. The MNRE’s recently announced guidelines and initiatives taken by the SECI for developing 1,000 MW of wind power projects through a transparent competitive bidding process have generated significant enthusiasm among wind industry players. However, several operational challenges need to be addressed to ensure its implementation.

On the demand front, offtake of renewable power and delays in payments by discoms have always been a cause of concern for developers in many states. However, discom participation in the Ujwal Discom Assurance Yojana (UDAY) scheme is expected to have a positive impact. Meanwhile, the lack of compliance with and non-enforcement of RPO targets by the SERCs will continue to affect the pace of renewable power offtake.

There have been many highs such as the adoption of UDAY  by 17 states, resulting in a substantial improvement in the financial status of discoms, and the entry of many new players in the sector like CLP, Ostro Energy, and IBC Solar. We saw the first ever-IPO in the US by an Indian renewable energy player – Azure Power. In addition, the solar rooftop market has expanded rapidly. With the government giving attractive subsidies to some consumer groups and new rooftop solar-specific concessional debt funding schemes becoming operational, we expect this sector to grow faster than utility-scale solar in the coming years.

The lows include increasing instances of grid curtailment, payment delays by many discoms (though we expect this situation to improve significantly by next year), the failure of state regulators to enforce RPOs, delays by states in signing PPAs despite completing the tender processes.

Which states performed better in terms of growth and achievements, and which states lagged behind?

Anish De

In 2015-16, Tamil Nadu (919 MW), Andhra Pradesh (435 MW) and Telangana (360 MW) led the growth in terms of solar capacity addition. In 2016-17 as well, Tamil Nadu (494 MW), Telangana (436 MW) and Andhra Pradesh (395 MW) are leading. Past leaders such as Rajasthan (31 MW), Gujarat (19 MW) and Madhya Pradesh (35 MW) have seen low solar installations this fiscal. Around 11 GW of solar is expected to be commissioned in the remaining part of 2016-17 with Karnataka (1,950 MW), Telangana (1,900 MW) and Andhra Pradesh (1,395 MW) expected to lead the way.

Many states such as Andhra Pradesh, Telangana, Madhya Pradesh, Karnataka and Rajasthan have proved to be attractive destinations for renewable energy investors over the past year, owing to their favourable policies for land acquisition, etc., ease of doing business, untapped potential sites and availability of evacuation infrastructure. In the past, states like Gujarat, Maharashtra and Tamil Nadu have performed well. However, renewable energy development in these states has slowed down on account of various reasons like transmission constraints, concerns regarding limited avenues for offtake, delays in timely payments and other regulatory concerns.

Vinay Rustagi

The southern states have been in the lead in terms of both installed capacity (Tamil Nadu) and pipeline capacity (Andhra Pradesh, Telangana and Karnataka). These four states alone account for nearly 50 per cent of the total installed and pipeline solar capacity in the country. Jharkhand came out with a large tender of 1,200 MW but failed to sign PPAs despite completing the auction process. The laggards are the big power consuming states such as Maharashtra, Gujarat and Uttar Pradesh, all for different reasons.

What are the key constraints impeding sector growth? What steps are needed to address these issues?

Anish De

The key constraints and solutions are:

  • Transmission bottlenecks: There is a need to expedite the Green Energy Corridors project.
  • Grid curtailment: Stronger enforcement of must-run status, robust transmission infrastructure, building greater flexibility in conventional coal and development of the ancillary services market are some solutions.
  • Unwillingness of utilities to sign PPAs: The state regulators need to mandate deadlines for utilities to sign PPAs  and enforce the RPO mechanism.
  • Significant financing requirement: What is required is the provision of equity and debt through innovative financing mechanisms at competitive terms as well as monetisation options.
  • Poor operating environment: Implementation of a single-window service in principle and a push towards ease of doing business.
  • Slow progress in the rooftop space: Enlisting discom support, innovative financing and business model innovation are some steps.
  • Lack of skilled manpower to manage the changing power sector environment: Focused actions need to be taken to evolve a very specific skilling strategy.

Ajit Pandit

The key factors that could affect the sector’s future growth are the development of adequate evacuation and transmission infrastructure; the availability of flexible resources and capacities of system operators to manage variable renewable energy generation; and the effective implementation of RPO targets. The government has planned green energy corridors to address the transmission issue. It is now imperative that these plans are put into action and the on-ground developments reflect the enthusiasm in the sector. Going forward, strengthening RPO compliance and ensuring effective grid integration should be the government’s two focus areas.

Vinay Rustagi

In our view, the biggest constraint for the sector is the limited capacity of the transmission grid to evacuate the increasing share of infirm power. Grid-related problems are already being witnessed in states with a large share of renewables, mainly the southern states and Rajasthan, and these are bound to escalate in the coming years. The government has launched initiatives such as green energy corridors, the storage mission and the smart grid mission to tackle this issue. However, it takes much longer to implement these programmes as compared to building more renewable capacity.

What is the outlook for the sector? How do you see the sector evolving in the coming years in terms of its contribution to the overall energy mix?

Anish De

Assuming an overall growth of 6 per cent per annum between 2015 and 2030, the peak demand is expected to be around 350 GW by 2030 and the energy requirement around 2,500 billion units (or about 2.5 times the 2015-16 levels). Serving this demand through a combination of non-fossil fuels (40 per cent) and fossil fuels (60 per cent), the overall capacity will have to be around 800 GW, a significant increase over the current levels. The disproportionate capacity expansion requirement is on account of the lower capacity factors of renewable energy sources, which will constitute the bulk of non-fossil fuel resources.

By 2030, when, under a 40 per cent non-fossil fuel scenario, the installed renewable energy capacity will be close to the peak demand in the system, there will be days when the actual renewable energy generation would be more than the overall requirement. In such situations, the system would need to have the capability to absorb the excess generation (storage devices), transfer the excess from a renewable energy-surplus region to a deficit region (through the transmission grid), and cycle the fossil fuel-based capacity. The prognosis thus is not for one response strategy or capability but a number of strategies acting in unison. There are many unknowns in the system pertaining to demand evolution, supply costs and, above all, the capabilities and costs of storage devices. It is impossible to predict the combination required and corresponding costs with precision. A better response strategy would be to plan for shorter durations, say 10 years instead of 20 or 30 years, but revise the plans more frequently, say every two years.

Ajit Pandit

Despite the challenges, the outlook for the sector is very positive. Concerns regarding energy security, climate change and the falling prices of renewable energy indicate significant growth prospects in the market. While the government has taken a number of steps to promote the sector, the emphasis now has to be on project development on the ground. The government is also focusing on supply-side intervention. The industry, too, has committed its resources towards enhancing the supply side. But the sector’s growth cannot just be supply-push; there has to be enough of a demand pull for the market to succeed. The discoms and power offtakers, and consumers will have to be encouraged to purchase the power generated from renewable sources.

Vinay Rustagi

The outlook for the sector is very positive as the fundamental drivers for renewable power remain very compelling. These are the growing power demand, and the need to reduce carbon emissions and improve energy security. Falling costs for both solar and wind are also extremely helpful in this regard. Over the next five years, we will see new renewable capacity of over 60 GW, a cumulative capacity growth of almost 150 per cent over the current capacity. In contrast, the aggregate power sector capacity is expected to go up by 50 per cent during this period. n
