RE share in India’s energy mix growing in spite of momentum loss: IEEFA

India’s electricity sector ambitions have been widely acknowledged as potentially transformational, and put India on the world centre stage in terms of re-invigorating the global drive towards the Paris Agreement. Prime Minister Narendra Modi has set ambitious, clear long-term targets. Despite some material near term headwinds that have developed over 2018/19, the level of ambition has been reinforced, with Power Minister R.K.Singh’s latest announcement being to target of 450GW of renewables by 2030, representing a total of 55% of planned capacity.

In this note we examine the progress to-date in 2019/20, particularly in light of the rapid deceleration in economic growth, which has in turn reduced near term electricity demand. October 2019 saw conventional power generation (excluding renewables) down 12.9% year-on-year for the month, with this decline continuing in November 2019. After a decade of GDP growth averaging over 6% annually, India has unexpectedly hit a near term economic slowdown. After 5.0% GDP growth in the June 2019 quarter, economists are estimating GDP growth may have slowed to as low as 4.2% in the September 2019 quarter, and the trends into the December 2019 quarter so far suggest a continuing deceleration.

Electricity generation across India, including renewables, grew 6.8% year-on-year in the June 2019 quarter. Electricity growth slowed to a still robust 5.3% year-on-year in the September 2019 quarter. But the December 2019 quarter has started with a record 12.9% decline in conventional generation (total including renewables is estimated at -9.6% year-on-year) in the month of October 2019. This decline has continued in the first three weeks of November, such that year-to-date 2019/20 electricity demand is 5.2% below the Central Electricity Authority (CEA) target.

The above chart highlights that the cumulative year to-date production from on-grid coal-fired power generation is down nearly 20,000 gigawatt hours (GWh) in absolute terms. With this being offset by a one-off skyrocketing of hydro-electricity generation (+18,000GWh on strong outputs from Northern Region all year and Western Region since the monsoon), total generation is up just 1.9% year-on-year year-to-date (solar and nuclear both up, wind and gas marginally down).

To put this in context, IEEFA’s estimates of India’s capacity and generation mix by the end of the 2019/20 year, based on electricity production growth lifting marginally in the last four months to average +2.6% year-on-year to 1,415 terawatt hours (TWh) overall.

Coal fired power capacity is on track to expand by some 4.6GW in 2019/20 (year-to-date +3.1GW), up marginally from the decade low net adds of just 3.5GW recorded in 2018/19. But on current trends coal-fired power generation is set to decline in 2019/20, so the sector is on track to report a capacity utilisation down at decade low of just 57.1%. In addition to excessive financial leverage and the inflationary impacts of rising coal and rail transportation costs, coal-fired power plant sector is grappling with utilisation rates 20-25% below design rates. Combined with the downward pressure of deflationary renewable energy tariffs, the financial distress in the thermal power sector is ongoing and proving difficult to solve.

Hydro generation is up 18TWh year to-date (20% generation growth relative to a 1% increase in capacity, showing this is almost all a one-off / seasonal high), putting this sector on track for a capacity utilisation rate approaching 39% relative to the 33% average over the last five years.

With no new nuclear capacity expansion near-term, a rising utilisation (72% in 2019/20 vs just 64% in 2018/19) is behind the rise in generation.

IEEFA forecasts cumulative renewable energy capacity to expand 17% year-on-year to 93.5GW by end of 2019/20, adding a total of 13.5GW in 2019/20 (relative to just 5.7GW to-date). But with a less windy monsoonal period, renewables generation is up only 9.3% year-on-year year to October 2019, utilisation rates are on track to tick down in 2019/20 to 19.2% (after 19.8% in 2018/19). Long term IEEFA expects renewables utilisation rates in India to progressively rise beyond 24-25% as newer technology, repowering of end-of-life wind farms and greater use of solar tracking / bi-facial modules progressively improves the sector average by 2030.

With renewable energy the lowest cost source of new power generation, and cost-effective fossil fuel shortages ongoing, investors continue to pivot away from Indian thermal power generation. Two-thirds of net new capacity installs across India to-date in 2019/20 are renewables (5.7GW vs 3.1GW of thermal). While coal-fired power generation is on-track to represent 71.8% of total generation in 2019/20 (54.5% of capacity), this is a decade low market share. For 2019/20, total generation from renewables is set to nearly double versus just three years earlier, exceeding 10% of total generation for the first time in 2019/20 (21% if large hydro-electricity is included), on 24.8% of installed capacity (37% of capacity including hydro).

A number of state-centre policy issues and some centre government policy contradictions (e.g. the dilemma of implementing ‘Make in India’ while maximising low cost renewable installation investments) have seen renewable energy installation momentum stall over the last 12-18 months, That over 5GW of tenders have been cancelled and another 6GW of auctions undersubscribed due to insufficient investor interest (mainly due to poor terms and excessively low tariff caps) reflects a number of policy headwinds.

Despite this, IEEFA would note that 38GW of renewable energy auctions have been completed since June 2017, and another 25GW of tenders have been called. And with solar module prices down 15% year-on-year to just US20c/w in 2019 in the Indian market, renewables are set to maintain or expand their cost advantage over expensive, polluting, emissions/water intensive thermal power generation. Technology developments and economic advantages strongly intertwine with a clear government ambition to put India in a position to transform its electricity sector over the coming decade. IEEFA expects the renewable sector to rebuild momentum into 2020.
