Because the planet heats up dangerously, companies are dealing with mounting public stress to use extra renewable electrical energy to cut back their carbon footprint.
Firms can accomplish that in a couple of methods. Small outlets can set up a couple of photo voltaic panels on their rooftops to maintain the lights on. Some companies could also be content material to purchase renewable power credit.
However a rising variety of companies – the likes of Apple, Microsoft and Nike – need to enter long-term contracts instantly with large-scale photo voltaic or wind farms, to safe a dependable provide of inexperienced electrical energy for many years to return.
Such company energy buy agreements (PPAs), as they’re recognized, are held up by companies as a key market-based enabler of renewable power progress. Business teams, such because the Asia Clear Vitality Coalition, have been fashioned to foyer governments to reform energy market guidelines and permit for company PPA offers.
Firms cheered this month when Vietnam, a regional manufacturing powerhouse, granted a high-level approval for company renewable power PPAs, seven years after it first signalled the intention to take action.
“This can be a vastly welcome step in Vietnam because the nation appears to be like to place itself as a frontrunner in renewables within the area,” mentioned Ollie Wilson, head of the RE100 marketing campaign, whose members have dedicated to help 100 per cent renewable electrical energy.
What are PPAs?
Briefly, they’re long-term energy provide contracts that may be signed for over 20 years at a go. Renewable power PPAs assist patrons lock in the inexperienced electrical energy they should meet their sustainability targets, whereas offering energy producers a assure for future revenue as they go about growing or fundraising for giant services equivalent to photo voltaic and wind farms.
PPAs additionally typically contain mounted energy pricing, which helps contributors buffer towards power value volatility. Within the frequent “contract for variations” deal construction, patrons prime up the revenue of energy producers in durations of low wholesale electrical energy costs. In return, mills present reductions for patrons when the market electrical energy charges rise too excessive.
However the capacity to forge such offers in fossil fuel-reliant Southeast Asia stays mosaicked, owing to each regulatory and technical roadblocks. Some nations solely enable for offers by way of state-owned utility monopolies. A number of additionally lack regulatory sweeteners, as an illustration allowing the sale of extra inexperienced energy to the nationwide grid.
What are the constraints in Southeast Asia?
Typically, restrictions round company renewable PPAs apply in situations the place the renewable power facility is situated away from the end-user, requiring electrical energy to be despatched by way of nationwide or non-public grids.
Sadly, this situation can also be the one which represents the very best renewables potential, because it permits, for instance, photo voltaic and wind services to be sited the place climate is sweet and land is ample, as an alternative of the place the electrical energy patrons are.
Off-site company PPAs can’t be cast in 5 of the 10 nations making up the Affiliation of Southeast Asian Nations (Asean) bloc:

Direct offers between inexperienced power mills and end-users are most often hampered by the system of electrical energy monopoly in place in a number of Southeast Asian nations, the place main state-owned utility corporations handle the nationwide electrical energy grid and provide energy to residents and companies.
Solely the Philippines and Singapore have liberalised energy markets. In Malaysia, Thailand and Vietnam, off-site company PPAs are enabled by exceptions the governments make to speed up renewables improvement. Earlier than Vietnam’s latest green-light, Thailand had final month permitted a 2-gigawatt company PPA pilot (Thailand’s whole energy capability is over 56 gigawatts). Malaysia’s scheme has an 800-megawatt quota.
“[The issue of corporate PPAs] is absolutely fairly a fancy situation for regulated markets, or partially regulated markets as we see them in Southeast Asia, as in comparison with a free market place,” mentioned Peter Godfrey, Asia Pacific managing director of suppose tank Vitality Institute.
State-owned utilities have traditionally taken on a social agenda, Godfrey famous, pointing to their mandates for subsidies and rural grid improvement that always don’t generate the most effective monetary returns. The flexibility for these utilities to “engineer improvement” might be hampered by the facility market liberalisation wanted to allow company PPAs, he added.
However there may be a component of enormous monopolies reluctant to relinquish the extent of management they’ve had for many years.
“[State utilities] don’t need to see the {dollars}, or ringgit, or rupiah, going out of their money movement. They see company PPAs as probably shedding their finest clients,” mentioned Grant Hauber, analyst on the Institute for Vitality Economics and Monetary Evaluation (IEEFA), referring to massive factories and manufacturing vegetation which have very massive energy wants.
“There are professional considerations over money movement and shedding huge clients. However [the reluctance to change] shouldn’t be on the expense of advancing the general power combine and satisfying the calls for of commercial clients with very robust mandates for inexperienced power,” added Hauber, Asia strategic power finance advisor on the suppose tank.
To be clear, PPAs might be signed with state utility monopolies. Indonesia’s Perusahaan Listrik Negara (PLN) makes use of such offers to each supply energy from impartial inexperienced energy producers and promote the output to massive companies equivalent to Amazon – on this occasion by way of a 210-megawatt solar energy deal signed in 2022. However with out competitors, patrons have restricted negotiating energy to push for PPAs that finest go well with their wants.
Laos, one of many area’s greatest hydropower producers, is exclusive in permitting impartial energy producers to signal electrical energy export PPAs, although patrons have tended to be the nationalised utilities of neighbouring states, equivalent to Vietnam Electrical energy or the Electrical energy Producing Authority of Thailand.
Company PPA dealmaking has been gaining momentum the place laws allow. Malaysia’s digital company PPA programme was absolutely subscribed final yr, with contributors together with Australian knowledge centre agency Airtrunk (contracting 30 megawatts) and Japanese meals oils producer ISF (capability undisclosed).
In Singapore, American knowledge centre agency Equinix signed an 18-year, 75-megawatt photo voltaic take care of native utility Sembcorp in April. Fb has had a 100-megawatt take care of photo voltaic supplier Sunseap in place since 2022.
Company renewable PPA capability rose to 26.3 gigawatts throughout Asia Pacific within the first half of 2023, consultancy Wooden Mackenzie reported. However that is nonetheless a small fraction of the 175.6 gigawatts worldwide by that point.
Off-site company PPAs normally take two types. Events can set up new non-public cables to switch electrical energy, an association usually reserved for the most important and costliest of offers, or in any other case commerce solely by way of renewable power certificates. Within the extra frequent latter association, termed “artificial” or “digital” PPAs, renewable energy is fed into the nationwide grid to be shared with all customers, however the purchaser will personal rights to assert all of the resultant carbon financial savings.
The injection of intermittent renewables into the nationwide grid may trigger harmful load imbalances, and could also be an element holding each regulators and the non-public sector again from extra company PPA offers. In previous years, nations equivalent to China and Vietnam needed to disconnect photo voltaic and wind farms from the facility grid to curtail extra provide, resulting in monetary losses.
Hauber mentioned such points will ultimately must be addressed, however not instantly, as renewables penetration remains to be very low in Southeast Asia. Photo voltaic and wind energy – the principle intermittent inexperienced energy sources – at present make up 9 per cent of the area’s whole capability, in response to nonprofit World Vitality Monitor.
Issues are simpler for on-site PPAs. Typically, no governments would oppose industrial services leasing out rooftop area for builders to construct photo voltaic panels, particularly if the facility produced is barely used on the identical premises. However such initiatives are usually smaller – whereas the most important wind and ground-level photo voltaic farms can attain gigawatts in capability, rooftop photo voltaic installations are usually counted within the single-digit megawatt vary.
Nonetheless, authorities insurance policies can whet or blunt investor urge for food for on-site company PPAs.
The place extra energy goes issues
A rooftop photo voltaic set up can be hard-pressed to supply all of the electrical energy its constructing wants, particularly at evening and in cloudy climate. However there would even be common situations of extra energy, say on weekends at a quiet manufacturing unit or workplace block.
The flexibility to promote extra solar energy again to the grid would supply extra revenue for energy producers, thus making them extra amenable to develop extra initiatives or signal extra offers. All else being equal, rooftop photo voltaic would possible face larger technology prices than massive photo voltaic farms because of the economies of scale.
“The elemental situation is that you simply’ve received to create adequate return on funding,” mentioned Godfrey.
However the sale of rooftop energy to the grid just isn’t attainable in lots of key Southeast Asian energy markets:

Indonesia, the most important Asean financial system, had allowed the sale of extra inexperienced energy from rooftops since 2018, however revoked it earlier this yr – a transfer that observers had mentioned would dent curiosity for future small-scale photo voltaic adoption.
Authorities had in parallel eliminated different charges for industrial customers, so the brunt of the destructive impacts can be felt as an alternative by households, who by no means needed to pay the enterprise charges within the first place.
Different jurisdictions are attempting to allow the sellback of rooftop solar energy, however are dealing with difficulties doing so. Brunei had began trialling a “internet metering” scheme since 2021, however doesn’t seem to have moved previous that stage, in response to data on its power division web site. Cambodia hinted at related measures final yr.
Below internet metering, companies use superior energy meters to trace how a lot solar energy they ship again to the grid, and accordingly obtain reductions on their electrical energy payments.
Company PPA and internet metering laws will not be the one components dictating the tempo of renewables uptake in Southeast Asia. The area can also be contending with beneficiant fossil gasoline subsidies and overcapacity, excessive infrastructure lending charges, and the shortage of a regional grid that may help extra intermittent power sources.
There are additionally requires governments to step up nationwide renewables procurement schemes, to additional add to inexperienced energy demand. Such schemes had been what propelled Vietnam’s renewables scene to Southeast Asia’s fore in 2018, though it has now emerged that the system was not nicely managed and led to the prolonged regulatory delay between 2021 and 2023. Builders now level to the Philippines, which has pledged annual auctions for brand spanking new renewables initiatives, as a brand new function mannequin.
However on the subject of enabling company renewable PPAs, all eyes at the moment are again on Vietnam, to see if the nation could make issues work.
“It’s early days right here. I need to see how issues begin taking part in out,” Hauber mentioned.
