Past their inexperienced credentials, solar energy initiatives have usually been marketed as low cost, modular and fast to put in, in comparison with fossil gasoline alternate options.
A utility-scale photo voltaic farm could possibly be inbuilt a couple of 12 months, a number of occasions quicker than a coal plant. New photo voltaic and wind initiatives is also delivering electrical energy cheaper than current nuclear and fossil gasoline crops, in keeping with a monetary report final 12 months.
This bodes effectively for Southeast Asia, which is simply beginning to dip its toes into wind and solar energy. The regional bloc, the Affiliation of Southeast Asian Nations, needs to get 23 per cent of its energy from renewables by 2030, up from 9 per cent in 2019.
Electrical energy demand within the area is rising at 6 per cent yearly – one of many quickest charges on the planet – in step with fast financial progress, industrialisation and rising populations.
With a rise in renewable vitality technology, energy grids should evolve to accommodate greater ranges of complexity to deal with readily dispatchable sources of electrical energy in addition to from extra variable ones corresponding to photo voltaic and wind.
Specialists forecast a bumpy outlook if the fitting infrastructure isn’t in place to help variable renewable vitality sources.
Muralidharan Ramakrishnan, the pinnacle of South and Southeast Asia vitality and utilities at credit standing company Fitch Rankings, pointed to the expertise of nations which have began their renewables drive earlier.
In 2015, China’s wind energy improvement spree noticed it personal a couple of third of the world’s wind technology capability. However that 12 months, 15 per cent of electrical energy produced from China’s wind farms went to waste. The determine reached practically 40 per cent in windy Gansu province. In all, US$3 billion {dollars} value of vitality was wasted.
Past stiff competitors from subsidised coal energy, the dearth of appropriate long-range transmission strains and vitality storage amenities contributed to the dumping of extra wind energy. When provide exceeded demand — for instance, when few individuals have been utilizing electrical home equipment within the noon however the wind was blowing sturdy — operators have been informed to disconnect.
It was the same scenario in India then, with the nationwide grid solely in a position to help about 5 per cent of renewables, leading to frequent disconnections from solar energy farms.
The quick tempo at which photo voltaic and wind initiatives can be accomplished implies that corresponding transmission infrastructure, which takes years to construct, will not be prepared in time, Ramakrishnan stated.
“That stated, the scenario [in China and India] has improved considerably over the previous three to 4 years, supported by strengthening of grid infrastructure,” added Ramakrishnan.
Southeast Asia might expertise related rising pains because it adopts extra renewable vitality. A report by accounting agency PwC final 12 months stated superior grid infrastructure is nonetheless not out there in nations like Brunei, Cambodia and Laos.
In recent times, some solar energy initiatives in Vietnam needed to reportedly dump 80 per cent of their generated electrical energy. Whereas the nation’s solar energy capability grew quickly in 2019 and 2020, the facility grids couldn’t sustain with the imbalances between peak provide – when the solar is shining, and peak demand – when households usually change on bigger home equipment within the night.
In a current report by engineering consultancy Black & Veatch that polled Asia’s electrical energy trade leaders, over a 3rd stated integrating renewable vitality is one among their most difficult points. Over 30 per cent think about the dearth of vitality storage and dependable transmission networks as threats to offering dependable service.

There’s a clear want to extend consciousness amongst governments, buyers and different public stakeholders across the position of transmission and grid administration on bettering the effectiveness of renewable integration

“There’s a clear want to extend consciousness amongst governments, buyers and different public stakeholders across the position of transmission and grid administration on bettering the effectiveness of renewable integration and attaining a profitable vitality transition,” stated Narsingh Chaudhary, government vice chairman and managing director of Black & Veatch Asia Pacific.
Governments have to take lead
Grid upgrades to help wind and solar energy are anticipated to value Southeast Asia US$1.2 trillion between 2019 and 2040.
The cash accounts for ensuring grids can deal with excessive provide variability, in addition to programs that may regulate electrical energy costs in actual time to raised match energy demand and provide.
Such programs have been much less vital when the facility sector was dominated by fossil fuels, since plant operators might regulate gasoline enter in response to demand adjustments.
New, longer transmission strains might be wanted as the place the solar shines and wind blows could also be distant from power-hungry city areas.
Specialists say such points have to be addressed by nationwide governments.
“In most nations in Southeast Asia, state grids are unable to maintain tempo with the fast progress of distributed technology as a consequence of an absence of funds or coordinated planning,” Chaudhary stated.
Daniel Morris, the clear vitality lead at inexperienced finance initiative Local weather Funding Funds (CIF), added that there’s public good concerns when planning for electrical energy networks.
“You get into points corresponding to zoning, like the place do grids go, are you displacing individuals, are you affecting individuals with their improvement?” Morris stated. “Leaving that to the personal sector by itself can lead to some points which might be possibly not helpful for the bigger objective of making an attempt to help the nation’s progress whereas getting on a zero carbon path.”
The CIF at present funds grid modernisation and vitality storage initiatives in Ukraine, Fiji, Colombia, Kenya, and Mali. 5 different nations, together with Indonesia, are on the waitlist.
Some nations in Southeast Asia are beginning to recognise the significance of centrally-led grid improvement. Vietnam’s energy improvement plan for this decade, PDP8, recognized grid improvement as a key precedence. Indonesia’s newest five-year vitality plan additionally describes the deployment of “good grids” to raised combine renewable vitality.
Renewable vitality is also higher managed by means of the short-term storage of extra energy. Batteries with hours-long capability is the present norm; there are additionally efforts to retailer extra electrical energy as hydrogen gasoline, which will be shelved for months.
The European Union, extensively seen as a frontrunner in renewables, had 40 gigawatts (GW) of storage capability in 2020. Renewables contributed 21 per cent to its vitality combine.
Asia Pacific had a storage capability of lower than 4 GW in the identical 12 months, and many of the capability was discovered exterior Southeast Asia, in nations corresponding to Australia, China, Japan and South Korea. The area solely acquired 7 per cent of its vitality from renewables in 2018.
“Case-by-case, location-by-location, solutions will fluctuate and nations want to attract from a special mixture of applied sciences, some which might be inexpensive at the moment and others that may develop into extra widespread and efficient as insurance policies are up to date and prices decline,” Chaudhary stated.
Watch the climate
More and more unhealthy climate related to a warming planet might scupper efforts to enhance Southeast Asia’s electrical energy infrastructure. The newest Intergovernmental Panel on Local weather Change report on local weather science observes stronger cyclones and predicts greater floods for the Southeast Asia area.
Late final 12 months, Hurricane Rai left 5 million individuals within the Philippines with out electrical energy. Comparable blackouts have occurred following main typhoons up to now decade.
“We’ve reached some extent the place you may’t ignore local weather threat, and actually, you in all probability pose extra threat to plans and investments by ignoring it,” Morris stated.
Present analysis factors to options corresponding to constructing transmission strains underground to guard towards typhoons, and making grids extra modular to stop widespread outages. Microgrids might additionally function a possible resolution for the electrification of distant areas, bypassing the prohibitive value of grid extensions.
The Intergovernmental Panel on Local weather Change additionally recommends holding design requirements for vitality belongings on par with present and projected local weather change.
