Indian solar industry witnessed huge capacity additions and expansions in 2017 globally. Not only China which led the growth in solar with 52 GW, but US, India, Japan, and Germany showed incredible growth trajectory. New solar markets like South Korea, Chile, and Turkey came forward and became GW markets in 2017.

Growing awareness and interest in solar within developing countries as well as dominant countries are estimated to show even a better result in 2018.

How solar will fare Globally

In 2018, China is estimated to continue to lead the growth; however, US’s present stance (dubious because of US president Mr. Donald Trump) may reduce America’s growth milestones in the New Year. Developing countries investing (more than developing countries-$131bn in 2016) in renewable energy will surely aid renewable energy (mainly solar) to account for more than 30% of total global energy generation by 2022. Although, coal will still be the primary energy source in 2018, renewable energy continuously growing is a strong sign that illustrates future energy scenario.

How Indian solar industry will fare in 2018

India has already claimed the mantle of third top solar market by overtaking japan. And the country is poised to overtake solar growth in EU by 2022. To reach that milestone, India is focusing on solar parks (more than 50 solar parks are going to be developed), which will add to Indian solar capacity immensely.

  • Policies and initiatives have made India an attractive business platform for the future (India reached 100th place in the list of Business ready countries). With focus on green energy and solar market, business in solar will increase in the country, leading to solar growth.
  • Government of India has also announced plans to beef up solar capacity through introducing 20 GW solar capacity projects. Even the tender process is also planned involving 3-6 GW capacity project introduction in Jan-March. New plans from MNRE to award 77 GW solar contract in the year 2018 is estimated to give Indian solar industry an incredible boost. Indian solar industry desperately needs focus on project introduction and reducing the time lag between auctioning and awarding the projects. In such a scenario, Government of India focusing on projects will bring positive impact for the industry.
  • Not just utility scale solar development, Indian solar industry is estimated to witness improvement in the rooftop solar sector as well. New investment coming in, and Government seeking to boost residential rooftop solar growth in 2018, will raise awareness in favour of solar.
  • Estimations of anti-dumping duty imposition on imported solar modules (results are due in 2018) will certainly offer domestic manufacturers in India a level playing field and allow India to control its own solar energy future, thus show incredible growth trajectory in 2018.
  • With the US hesitant to go all in solar (due to US president Mr. Donald Trump’s convictions), India can make a decisive move to claim a larger portion of the solar export market in 2018. With anti-dumping duty imposition in effect (hopefully in 2018) and US slowing down, It is truly a great opportunity for India to focus on domestic manufacturing capacity enhancement, which will establish India as a leader in solar export market again (in FY13-14 solar export stood at $282.58 mn, and in FY16-17- $69.10 mn).

As the data and initiatives point, 2018 is going to be a great year for solar. However, there are still challenges to be tackled to unleash and utilize Indian solar potential. Improving the policy landscape and adding new bits to favour domestic solar capacity enhancement, clearing out confusion regarding DCR projects, clarifying GST, stopping PPA re-negotiation, mandating RPO fulfilment, and stabilizing solar tariff will surely help India to harvest on the opportunities that 2018 is here with.

Global solar growth clearly explains the future of energy. Moreover, it is the right moment for India to make bold decisions to adopt solar, securing the future of the country.

Government support and encouragement has helped Indian solar industry to reach ~16.6 GW solar capacity. Government of India should be commended for bringing in (and incentivizing) solar venture for private players, which has played a major role in green energy capacity ascension. It is a fact that solar in India has scaled a great height and future looks rosy with new projects, plans and policies coming. However, it is also important to highlight the challenges that required to be addressed. And EPC operations is one of the challenges in question.

Engineering complexity involving EPC operations is less complex than that of conventional energy plants. However, EPC solution providers in India have faced challenges in construction and delays in reaching completion time line due to bureaucratic hurdles. EPC operations within India require interaction and dealings with internal teams, sub-contractors, local bodies, clients, vendors etc. in such a scenario bureaucratic delays cause issues in managing operation profitability.

Generally, the issues that hinder EPC processes are- land acquisition, logistics, and engineering. Inspecting each of these issues individually can help in getting a better idea of situation.

Land Acquiring Related Issues

More than 5 acres of land is needed to install 1 MW of solar plant. Therefore, it is easy to understand that solar growth has a land requirement. In addition, the there are multiple parameters like- soil geology, compatible topography etc that needs to be checked before selecting a land for solar installation.

Challenges of finding the right land are not the only hurdles, getting a cost agreement for the land is also an issue since in India land holdings are generally divided into several family members. Thus, discussion with all the stakeholders and getting an agreement takes time, ultimately delaying project timeline.

Plus, regulatory bottlenecks like- lands identified as farmlands cannot be taken for solar installation. It is a fact that Government has done exceptional work in building solar parks, which offers already purchased and prepared land ideal for solar installations. States like- Karnataka, Andhra Pradesh, Uttar Pradesh, Rajasthan have already developed policies that simplify land acquisition. Such processes should be followed in every state within India to support solar growth.

Logistics Related Challenges

Generally, lands selected for large solar installations are far from residential areas (ground mounted). And since transportation in remote areas of India is still not well developed, bringing in all required components for solar installation at desired spot seems a challenging, time consuming, and expensive task. Even if EPC contractors take on the added responsibility and risk of getting their plant related equipment in a remote location, adequate standard (safe) road availability puts risk of damage to their precious solar plant equipment. If EPC contractors to opt for insurance for their products, added cost affects upon the financial and construction plans.

India needs to focus on better road development and skill improvement for handling solar EPC materials. Increase in awareness can help the EPC contractors get skilled transporters and on standard roads.

Engineering Challenges

Innovative engineering systems and processes can help in rapid installation of the project. However, for innovative engineering system to be established, EPC players need detailed geotechnical reports, solar resource availability, and ambient conditions. However, as Indian Government doesn’t have such important information in store, actions like- maintaining stability of the installations, levelling the field, protecting against wind load, minimizing repairing cost, becomes extremely challenging.

Way Forward

Solar is gaining worldwide acceptance and is believed to be able in phasing out fossil fuel in near future. This is a great opportunity for India to utilize this timeframe through initiatives and investments for growth in solar. Better utility side cooperation, adding feasibility in interconnection processes, and supporting solar growth by enforcing policy implementations can help EPC players, thus aiding solar progress.

Looking back at my 2017 post on developments in 2016, it becomes clear that the past twelve months have been more consolidation than progress in terms of carbon market development. It also means that the coloured map (below) hasn’t really changed, apart from a slight set-back and the very positive addition of Singapore.

A big story that emerged in 2016 was the prospect of a nationwide emissions trading system in China. Observers waited throughout 2017 for the formal commencement or at least an announcement, but news didn’t come until mid-December of an imminent launch. Rather than an economy wide cap-and-trade system, the government announced that an emissions rate based system would commence in the electricity sector. Harvard’s Rob Stavins has written extensively about it in a recent blog post.

The Chinese carbon market will double the share of global CO2 emissions covered by worldwide carbon-pricing systems to almost 25 percent.

China wasn’t the only country in the news. Also within the Asian economy, Singapore announced the start of a carbon tax based system from 2019, with a draft Bill appearing for consultation during 2017. The tax will be applied on power stations and other large direct emitters which produce more than 25,000 tonnes of carbon dioxide equivalent of greenhouse gases a year. There are currently 30 to 40 of such large emitters, mainly from the petroleum refining, chemicals and semiconductor sectors. The proposed tax will be around S$10-$20 per tonne CO2.

In North America, progress was mixed. The focus continued to be on Canada with the September announcement that Ontario had entered into an agreement to formally link its carbon market with markets in Quebec and California effective January 1, 2018. The Agreement will allow the governments of Ontario, Quebec and California (the Parties) to hold joint auction of greenhouse gas emission allowances and to harmonize regulations and reporting requirements. An important addition to this was the passage of a Bill in California to extend that State’s cap-and-trade system through to 2030. But with the announcement that the US would be leaving the Paris Agreement and that the Administration would be rolling back the Obama Clean Power Plan, progress in the rest of the country was muted.

In Central Asia, the Kazakhstan emissions trading system remained suspended (hence the change from green to orange), but following an announcement by the government, this should revert to operational status in 2018.

South Africa also moved forward slightly, with a further consultation announced on its draft carbon tax legislation.

Here in the EU, the ETS continued, but 2018 saw much needed reforms agreed. The main elements of the agreement are:

  • The linear reduction factor will be 2.2 % from 2021;
  • Each year from 2019 to 2023, 24 % of the cumulative surplus of allowances will go to the Market Stability Reserve; from 2023 the allowances held in the reserve above the total number of allowances auctioned during the previous year should be cancelled;
  • Conditional lowering of the auction share by 3 % of the total quantity if needed, to avoid application of the cross-sectoral correction factor;
  • Member States may voluntarily cancel allowances to offset national climate and energy policies that reduce the demand.

The EU ETS expanded slightly with the agreement of a link with the Swiss ETS, although it may be some time before this comes into practice. The ratification of the agreement will require the approval of the Council and Parliament, which is expected in early 2018. When parties are technically ready to connect the two systems, they will formally deposit their instruments of ratification. The agreement will enter into force at the start of the following year.

As the year concluded and nations met in Bonn for COP23, it was also clear that carbon pricing, both through taxation or a trading system was being widely considered. This offers considerable hope for the years to come.
