India: Improved Monsoon Winds Help Power Producers in 2018 

After a prolonged period of decline, wind speeds in India during the 2018 monsoon season were significantly higher than normal; and up to 20% higher than long-term averages in some regions, according to wind performance maps Vaisala published recently. These higher wind speeds will benefit wind farm production; this is welcome news for wind energy operators and investors, who have faced several years of lower-than-normal wind energy production during the monsoon period.

Because the monsoon season typically has the highest wind speeds of the year, the below-average wind resource in recent years has had a disproportionate impact on wind energy production and has caused concern in the sector.

Increased Wind Speeds Counter Recent Pattern of Decline: In contrast to recent years, Vaisala’s measurements and analysis of the monsoon season show that wind speeds across India were up to 20% higher than the long-term average for periods of July, August and September – with notably strong performance in key wind power producing states, Tamil Nadu and Andhra Pradesh. The increase runs counter to an observable trend over the past 20 years of declining wind speeds, and stands in sharp contrast to resource data from the monsoon season in three of the past four years, which shows that wind speeds dropped well below the historic average.

Increasing Investor Confidence with a Data-driven Approach: This recent change in fortune will be welcomed by renewable energy investors in India and may help adjust perceptions of wind sector underperformance at a time when many energy assets are under scrutiny by lenders.  Investment in the renewables sector has slowed following the recent cancellation of several large wind and solar tenders where the bids did not achieve the benchmark ceiling tariff.

While this year’s monsoon wind performance was good news for power producers, wind energy developers must still find a way to demonstrate the value of investment in their wind projects, faced with long-term variability in wind speeds. Key to this is a scientific, data-driven approach to wind resource assessment.

“Improved resource performance over this past monsoon season, when set in the right context, can show investors the sector has real potential, and should signal a boost to investor confidence in India’s wind industry,” said Rajnikanth Umakanthan, Managing Director of 3TIER India, a Vaisala subsidiary. “The variability we see in resource performance underlines the value of using a long-term climate context when performing wind resource analysis. Currently, financial performance is judged against ever-lower tariffs – even in less windy states – so it is important to contextualise that with a longer-term view of climate effects.” Information about worldwide wind anomalies for the past 35 years can be accessed via the Vaisala Climate Reference Tool.

Weather provides the fuel for renewable energy projects and is one of the largest variables impacting production. Vaisala uses more than 80 years of weather expertise to help the global renewable energy industry develop and operate wind and solar projects better, faster and more efficiently. Its measurement, assessment, forecasting and asset management products and services leverage proven science and advanced technology to mitigate the impact of weather risks on energy generation and support profitable decision-making across the entire project life cycle, from greenfield prospecting and due diligence through operational forecasting and plant optimisation.

Corporate Sourcing of Renewables Growing, Taking Place in 75 Countries

Companies in 75 countries actively sourced 465 terawatt hours (TWh) of renewable energy in 2017, an amount close to the overall electricity demand of France, according to the report from the International Renewable Energy Agency (IRENA). With the continued decline in the costs of renewables, the report suggests, corporate demand will continue to increase as companies seek to reduce electricity bills, hedge against future price spikes and address sustainability concerns.

Arsenal Unveil Battery Storage System: First Of Its Kind At A UK Football Club

Arsenal Football Club has unveiled a battery storage system (BSS) to store enough energy to run the 60,000 seater Emirates Stadium from kick-off to full time. It follows a unique collaboration with Pivot Power to install a 2MW/2.5MWh lithium ion BSS, with funds managed by Downing LLP. The project, the first of its kind in the UK, will also save club money as it works to support low-carbon plans. The BSS allows Arsenal to avoid peak power prices, buying electricity when it is cheap and storing it for use when prices are high. Typically, energy can cost three times more at peak times than overnight. The installation maintains Arsenal as the leader in sustainability in sport following its commitment to clean energy with Octopus Energy in 2016.

Battery Boom: Wind And Solar Can Generate Half Of Worldwide Electricity By 2050

Coal is to shrink to just 11% of global electricity generation by mid-century, from 38% now, as costs shift heavily in favour of wind, solar and batteries. Wind and solar are set to surge to almost “50 by 50” – 50% of world generation by 2050 due to reductions in cost. “Cheap battery storage means that it becomes increasingly possible to finesse the delivery of electricity from wind and solar so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear.”

Wind: China Maintains Emerging Markets Top Spot Following 19.7GW Build Boom

Wind industry intelligence service A Word About Wind has launched its Emerging Markets Attractiveness Index report for 2018, which provides insight and analysis into the most attractive emerging markets for wind companies. The index, now in its second year, ranks the top 30 emerging markets that investors should consider when investing in wind in Europe, Africa, Asia and Latin America. The list considers factors including political and economic stability for investors, alongside the growth of electricity demand and potential for wind growth, in order to rank the countries by overall potential. As with last year’s report, China tops the list and the ongoing trade war with the US shows no sign of slowing China’s formidable growth.
