More of a good thing – is surplus renewable electricity an opportunity for early decarbonisation?

Published

on

We are entering a world where renewables will make up an increasing share of our electricity supply –the electricity sector was the leading sector for energy investment in 2018, the third year in a row that this has occurred.

This trend is set to continue. In WEO 2018’s New Policies Scenario, 21% of global electricity production is projected to come from variable renewables by 2040, up from 7% in 2018, supported by about $5.3 trillion of investment. The EU share is even higher at around 39%. In our more ambitious Sustainable Development Scenario, which aims to get energy system emissions down to levels consistent with the Paris goals, variable renewables are projected to supply 38% of global electricity in 2040 (44% in the EU), a level that would require nearly $8.5 trillion of generation investment.

Regardless of scenario, this rapid expansion of renewables will inevitably lead to particular challenges to operating power systems. This is best highlighted by the so-called duck curve, made famous by the California ISO.

The curve was developed to show the impact of increasing distributed solar PV capacity on the demand for grid electricity.  As solar PV capacity grows, the demand for grid electricity falls during the day with the greatest decrease in the middle of the day when PV production is highest – the belly of the duck.  In the afternoon as PV production declines towards sunset, the demand for grid electricity can grow quite quickly – the neck of the duck.

The duck is growing faster than anticipated. Five years ago, the California ISO had expected California midday demand to drop over 40% on a sunny spring day by 2020 thanks to the growth of small solar PV systems. In fact, by 2018, the spring mid-day demand on the high voltage system had already decreased by two thirds. The consequent increase in supply required in the late afternoon as solar production recedes, was already close to 15 GW, significantly greater than the 2020 anticipated level of 13 GW.

The result is that some excess supply needs to be curtailed to balance the system. While the percentages of solar and wind production that have to be curtailed in California are rather small, in other jurisdictions the share is more significant.

In China, for example, the national average for wind curtailment was around 7% in 2018, with much higher levels in certain provinces. In the Canadian province of Ontario about one quarter of variable renewable generation in 2017 had to be curtailed, along with cuts in nuclear and hydropower output. This was in a jurisdiction where wholesale market prices were zero or negative almost one-third of that year.

The challenges are clear – a world with higher shares of variable renewable energy (VRE) – i.e., wind and solar PV – will face challenges with integration. This is a priority area of work for the IEA, and we are focused on providing insights on the issues and technologies that can be employed to deal with higher shares of variable renewables.

One of these insights is that renewables integration can be divided into a set of six phases dependent partly on the share of variable renewables in the system, but also on other system-dependent factors such as the share of storage hydro and interconnections.

Two countries have already reached Phase 4. Denmark, which has been a leader, has the significant advantage of strong interconnections to handle both surpluses and shortfalls. Ireland has much weaker interconnections and additional measures have been needed to ensure short-term system stability.

No country is yet in Phase 5 (where production can exceed demand) or in Phase 6, where seasonal storage solutions would be needed to match supply and demand.

Strong renewables policies are expected to continue to favour wind and solar power for the foreseeable future.  This will mean that by 2030, we expect more countries, particularly in Europe, to evolve to these higher phases.

Too much of a good thing?

As more countries move to higher shares of VRE, it appears that there could be “too much of a good thing” – excess generation that may have to be curtailed and appears as wasteful.

The tendency is to treat this primarily as a technology problem for the power system to solve. Indeed part of the solution will lie in improvements in technology. We will need some form of energy storage to convert the excess at one time of day into necessary power system supply at another. Smart grids, especially smarter distribution systems, will be better able to manage increasing shares of renewables as well – and they too will likely have more energy storage. And finally, the growth of EVs (currently driving global battery demand) represents a huge potential source of storage and demand-side flexibility as well.

But treating this only as a technical problem is missing the economic perspective. Trillions of dollars of investment in renewables is expected in the coming years, and so there is a risk that billions of dollars of renewable electricity – zero marginal cost, zero carbon – could be wasted.  

Economists have their own tools for solving these type of problems. Many would see not a problem but an opportunity – offering surplus electricity available at a zero (or low) price to customers during periods of surplus is a means to manage this surplus efficiently.

Dynamic pricing of wholesale electricity is often proposed as a mechanism to efficiently manage peak demand of electricity – to charge more when electricity is scarce.  Not surprisingly, passing on high wholesale prices as high retail prices has been met with customer resistance, and the uptake of dynamic pricing has been rather limited.

However, if low wholesale prices were passed on as low retail prices, we would expect customers to be more accepting.  While most small customers might not be expected to respond on their own, low dynamic prices create opportunities for innovators to develop technologies and processes that would make it easy and profitable for the customer to respond.  Many of these will involve using the electricity to replace, at least in part, an energy service provided by fossil fuels. In this way, it can help hasten the decarbonisation goal of the clean energy transition.

Barriers to efficient pricing

Unfortunately for now, there are a range of barriers in our current policies that prevent electricity customers from seeing these prices: the level of electricity taxes, the design of electricity tariffs and more broadly our approach to the electricity demand side. This means there is a need to change outdated policies.

Much of our electricity policy dates from a period where wasteful consumption led to an increasing number of power plants – particularly fossil and nuclear plants. Indeed, electricity was considered to be a particularly inefficient means of achieving a level of energy service.

This has affected the way and level at which electricity is taxed, the way regulated prices are designed, and perhaps most challenging of all, how we address demand side policies and particularly electricity efficiency.

But now we are entering a different era, an era where most of the incremental electricity generation will come from wind and solar power. How should it change our taxation, rate setting and electricity efficiency policies?

Economics should guide us so that:

  1. Taxes are fixed in an efficient way, in order to distort as least as possible consumers and producers decisions
  2. Consumption is efficient, both through taxes and regulated tariffs
  3. Ensuring end-use energy consumption is carbon-efficient

Electricity taxes that exist in many countries today were set as a result of either a deliberate policy to reduce electricity consumption in energy importing countries (Europe) and/or environmentally conscious jurisdictions (Europe, California). They have also provided an easily enforceable tax base for municipalities and subnational jurisdictions. These taxes can be quite substantial, amounting to over half the cost of power for households in some European countries.

Yet many of the reasons for taxing electricity heavily are no longer valid. The emissions argument in particular makes little sense in highly decarbonised power sectors such as Sweden, France, or Switzerland.

In addition to taxation, pricing systems tend to discourage consumption regardless of how clean the production is. There are countries where, paradoxically, a high level of renewable penetration discourages the consumption of renewable energy.

Germany is probably the best known example. Although prices in the wholesale market can fall to zero when wind and solar power are particularly prolific, the end user cannot buy electricity at the real time price, but even if that were possible, it would mean paying the EEG payment (which is intended to recover the cost of renewables) which is currently 6.405 euro cents per kWh.  This means that the end user incentive to use that renewable energy to substitute for fossil fuels in their own consumption is blunted.

What needs to be done instead is to encourage customer response based on the real-time price for power. Most other costs should no longer be recovered on a per kWh basis.

Getting prices right for the end consumer means also addressing regulated prices such as for networks where these are separately specified. Networks remain largely fixed cost entities in developed economies where demand has not been growing. For electricity customers, the value of the electricity network is as the provider of reliable electricity service – a value that is not directly related to the quantity of power delivered.  Increasingly, as more and more customers generate their own electricity, the value of the network is evolving to become a platform to sell some of that power or other electricity services.

Moving towards a fixed charge would recognize the value of the network service for customers. It would also alleviate concerns that customers choosing to self-generate are not contributing sufficiently to the costs of using a network they still require.

Finally, demand-side policies should be designed in a way that minimizes both costs to consumers and their carbon footprint.

As renewables continue to grow and increasingly face curtailment, the optimal policy may no longer to be to encourage electricity conservation. Instead, demand side policies that encourage carbon conservation might be more efficient.

The figure above shows how the prices charged for consuming an additional kWh of electricity in each US jurisdiction is compared to the social marginal cost of producing that electricity. Red means the social cost of production exceeds the marginal cost, suggesting that marginal prices are too low and interventions such as conservation programs could be efficient. Conversely, in the deep blue regions, electricity prices are too high, suggesting that conservation and net metering programs need to be reconsidered.

Ultimately, when marginal prices for clean electricity consumption are adjusted downwards the viability of electrification increases – which can replace other end-uses of fossil fuels.

In fact, these changing circumstances are beginning to be recognized. The California energy regulator, the California Public Utilities Commission, has recently ruled that utility energy efficiency programs can include those that encourage customers to substitute electricity for fossil fuels. 

More of a good thing

The good news is that the direction for electricity investments is positive, with the share of renewables likely to grow rapidly spurred by government policies and falling costs. Yet the resultant growth of wind and solar power will lead to new integration challenges for today’s power systems and these challenges will become greater over time. 

Yet solving those challenges will also lead to economic opportunities in the energy system – opportunities to reduce costs, waste and emissions by making electricity available in substitution of fossil fuels.

Policies are central to realising these opportunities, by reforming electricity taxation, getting regulated prices right, and emphasizing carbon conservation above electricity conservation. The right price signals will encourage the innovation needed to advance the clean energy transition. And in the end, customers will have more of a “good thing”:  greater access to cheaper, clean power.

Energy transition is a global challenge that needs an urgent global response

Published

on

COP26 showed that green energy is not yet appealing enough for the world to reach a consensus on coal phase-out. The priority now should be creating affordable and viable alternatives 

Many were hoping that COP26 would be the moment the world agreed to phase out coal. Instead, we received a much-needed reality check when the pledge to “phase out” coal was weakened to “phase down”. 

 This change was reportedly pushed by India and China whose economies are still largely reliant on coal. The decision proved that the world is not yet ready to live without the most polluting fossil fuels. 

 This is an enormous problem. Coal is the planet’s largest source of carbon dioxide emissions, but also a major source of energy, producing over one-third of global electricity generation. Furthermore, global coal-fired electricity generation could reach an all-time high in 2022, according to the International Energy Agency (IEA).

 Given the continued demand for coal, especially in the emerging markets, we need to accelerate the use of alternative energy sources, but also ensure their equal distribution around the world.

 There are a number of steps policymakers and business leaders are taking to tackle this challenge, but all of them need to be accelerated if we are to incentivise as rapid shift away from coal as the world needs. 

 The first action to be stepped up is public and private investment in renewable energy. This investment can help on three fronts: improve efficiency and increase output of existing technologies, and help develop new technologies. For green alternatives to coal to become more economically viable, especially, for poorer countries, we need more supply and lower costs.

 There are some reasons to be hopeful. During COP26 more than 450 firms representing a ground-breaking $130 trillion of assets pledged investment to meet the goals set out in the Paris climate agreement. 

 The benefits of existing investment are also becoming clearer. Global hydrogen initiatives, for example, are accelerating rapidly, and if investment is kept up, the Hydrogen Council expects it to become a competitive low-carbon solution in long haul trucking, shipping, and steel production.

 However, the challenge remains enormous. The IEA warned in October 2021 that investment in renewable energy needs to triple by the end of this decade to effectively combat climate change. Momentum must be kept up.

 This is especially important for countries like India where coal is arguably the main driver for the country’s economic growth and supports “as many as 10-15 million people … through ancillary employment and social programs near the mines”, according to Brookings Institute.  

This leads us to the second step which must be accelerated: support for developing countries to incentivise energy transition in a way which does not compromise their growth. 

Again, there is activity on this front, but it is insufficient. Twelve years ago, richer countries pledged to channel US$100 billion a year to less wealthy nations by 2020, to help them adapt to climate change. 

The Organization for Economic Cooperation and Development estimates that the financial assistance failed to reach $80 billion in 2019, and likely fell substantially short in 2020. Governments say they will reach the promised amount by 2023. If anything, they should aim to reach it sooner.

There are huge structural costs in adapting electricity grids to be powered at a large scale by renewable energy rather than fossil fuels. Businesses will also need to adapt and millions of employees across the world will need to be re-skilled. To incentivise making these difficult but necessary changes, developing countries should be provided with the financial support promised them over a decade ago.

The third step to be developed further is regulation. Only governments are in a position to pass legislation which encourages a faster energy transition. To take just one example, the European Commission’s Green Deal, proposes introduction of new CO2 emission performance standards for cars and vans, incentivising the electrification of vehicles. 

This kind of simple, direct legislation can reduce consumption of fossil fuels and encourage industry to tackle climate change.

Widespread legislative change won’t be straightforward. Governments should closely involve industry in the consultative process to ensure changes drive innovation rather than add unnecessary bureaucracy, which has already delayed development of renewable assets in countries including Germany and Italy. Still, regardless of the challenges, stronger regulation will be key to turning corporate and sovereign pledges into concrete achievements. 

COP26 showed that we are not ready as a globe to phase out coal. The priority for the global leaders must now be to do everything they can to drive the shift towards green energy and reach the global consensus needed to save our planet.

Pakistan–Russia Gas Stream: Opportunities and Risks of New Flagship Energy Project

Published

on

Russia’s Yekaterinburg hosted the 7th meeting of the Russian-Pakistani Intergovernmental Commission on Trade, Economic, Scientific and Technical Cooperation on November 24–26, 2021. Chaired by Omar Ayub Khan, Pakistan’s Minister for Economic Affairs, and Nikolai Shulginov, Russia’s Minister of Energy, the meeting was attended by around 70 policy makers, heads of key industrial companies and businessmen from both sides, marking a significant change in the bilateral relations between Moscow and Islamabad.

Three pillars of bilateral relations

Among the most important questions raised by the Commission were collaboration in trade, investment and the energy sector.

According to the Russian Federal Customs Service, the Russian-Pakistani trade turnover increased in 2020 by 45.8% compared to 2019, totaling 789.8 million U.S. dollars. Yet, there is still huge potential for increasing the trade volume for the two countries, including textiles and agricultural products of Pakistan and Russian products of machinery, technical expertise as well as transfer of knowledge and R&D.

Another prospective project discussed at the intergovernmental level is initiating a common trade corridor between Russia, the Central Asia and Pakistan. Based on the One-Belt-One-Road concept, launched by China, the Pakistan Road project is supposed to create a free flow of goods between Russia and Pakistan through building necessary economic and transport infrastructure, including railway construction and special customs conditions. During the Commission meeting, both countries expressed their intention to collaborate on renewal of the railway machines fleet and facilities in Pakistan, including supplies of mechanized track maintenance and renewal machines; supplies of 50 shunting (2400HP or less) and 100 mainline (over 3000HP) diesel locomotives; joint R&D of the technical and economic feasibility of locomotives production based in the Locomotive Factory Risalpur and other. The proposed contractors of the project might be the Russian Sinara Transport Machines, Uralvagonzavod JSC that stand ready to supply Pakistan Railway with freight wagons, locomotives and passenger coaches. In order to engage import and export activities between Russian and Pakistani businessmen, the Federation of Pakistan Chamber of Commerce signed a memorandum with Ural Chamber of Commerce and Industry, marking a new step in bilateral relations. Similar memorandums have already been signed with other Chambers of Commerce in Russian regions.

— Today, the ties between Russia and Pakistan are objectively strengthening in all areas including economic, political and military collaboration. But we, as businessmen, are primarily interested in the development of trade relations and new transit corridors for export-import activities. For example, the prospective pathways of the Pakistan-Central Asia-Russia trade and economic corridor project are now being actively discussed at the intergovernmental level, — said Mohsin Sheikh, Director of the Pakistan Russia Business Council of the Federation of Pakistan Chambers of Commerce and Industry. — For Islamabad, this issue is one of the most important. Based on a similar experience of trade with China, we see great prospects for this direction. That is why representatives of Pakistan’s government, customs officers, diplomats and businessmen gathered in Yekaterinburg today.

However, the flagship project of the new era of the Pakistan-Russia relations is likely to be the Pakistan Gas Stream. Previously known as the North-South Gas Pipeline, this mega-project (1,100 kilometers in length) is expected to cost up to USD 2,5 billion and is claimed to be highly beneficial for Pakistan. Being a net importer of energy, Pakistan will be able to develop and integrate new sources of natural gas and transport it to the densely populated industrialized north. At the same time, the project will enable Pakistan—whose main industries are still dependent on the coal consumption—to take a major step forward gradually replacing coal with relatively more ecologically sustainable natural gas. To enable this significant development in the Pakistan’s energy sector, Moscow and Islamabad have made preliminary agreements to carry on the research of Pakistan’s mineral resource sector including copper, gold, iron, lead and zinc ores of Baluchistan, Khyber Pukhtunkhwa and Punjab Provinces.

A lot opportunities but a lot more risks?

The Pakistan Stream Gas Pipe Project undoubtedly opens major investment opportunities for Pakistan. Among them are establishment of new refineries; the launch of virtual LNG pipelines; building of LNG onshore storages of LNG; investing in strategic oil and gas storages. Yet, it seems that Pakistan is likely to win more from the Project than Russia. And here’s why. The current version of the agreement signed by Moscow and Islamabad has been essentially reworked. According to it, Russia will likely to receive only 26 percent in the project stake instead of 85 percent as it was previously planned, while the Pakistani side will retain a controlling stake (74 percent) in the project.

Another stranding factor for Russia is although Moscow will be entitled to provide all the necessary facilities and equipment for the building of the pipeline, the entire construction process will be supervised by an independent Pakistani-based company, which will substantially boost Pakistan’s influence at each development. Finally, the vast bulk of the gas transported via the pipeline will likely come from Qatar, which will further strengthen Qatar’s role in the Pakistani energy sector.

Big strategy but safety first

The Pakistan Stream Gas Pipeline will surely become an important strategic tool for Russia to reactivate the South Asian vector of its foreign policy. Even though the project’s aim is not to gain a fast investment return and economic benefits, it follows significant strategic goals for both countries. As Russia-India political and economic relations are cooling down, Moscow is likely to boost ties with Pakistan, including cooperation in economy, military, safety and potentially nuclear energy, that was highlighted by Russian Foreign Minister Sergey Lavrov during visit to Islamabad earlier this year. Such an expansion of relations with Pakistan will allow Russia to gain a more solid foothold in the South Asian part of China’s BRI, thus opening up a range of new lucrative opportunities for Moscow.

Apart from its economic and political aspects, the Pakistan Stream Project also has clear geopolitical implications. It marks Russia’s growing influence in South Asia and points to some remarkable transformations that are currently taking place in this region. The ongoing geopolitical game within the India-Russia-Pakistan triangle is yet less favorable for New Delhi much because of the Pakistan Stream Project. Even though the project is not directly aimed to jeopardize the India’s role in the region, it is considered the first dangerous signal for New Delhi. For instance, the International “Extended troika” Conference on Afghanistan, which was held in Moscow last spring united representatives from the United States, Russia, China and Pakistan but left India aside (even though the latter has important strategic interests in Afghanistan).

With the recent withdrawal of the U.S. military forces from Afghanistan, Moscow has become literally the only warden of Central Asia’s security. As Russia is worried about the possibility of Islamist militants infiltrating the Central Asia, the main defensive buffer in the South for Moscow, the recent decision of Vladimir Putin to equip its military base in Tajikistan, which neighbors Afghanistan, seems to be just on time. Obviously, Islamabad that faces major risks amidst the Afghanistan crisis sees Moscow as a prospective strategic partner who will help Imran Khan strengthen the Pakistani efforts in fighting the terrorism threat.

How wind power is transforming communities in Viet Nam

Published

on

In two provinces of Viet Nam, a quiet transformation is taking place, driven by the power of renewable energy.

Thien Nghiep Commune, a few hundred kilometres from Ho Chi Min City, is a community of just over 6,000 people – where for years, people relied largely on farming, fishing and seasonal labour to make ends meet.

Now, thanks to a wind farm backed by the Seed Capital Assistance Facility (SCAF) – a multi-donor trust fund, led by the United Nations Environment Programme (UNEP) – people in the Thien Nghiep Commune are accessing new jobs, infrastructure and – soon – cheap, clean energy. The 40MW Dai Phong project, one of two wind farms run by SCAF partner company the Blue Circle, has brought new hope to the community.

For the 759 million people in the world who lack access to electricity, the introduction of clean energy solutions can bring improved healthcare, better education and affordable broadband, creating new jobs, livelihoods and sustainable economic value to reduce poverty.

“It’s not only about the technology and the big spinning wheel for me. It’s more about making investment decisions for the planet and at the same time not compromising on the necessity that we call electricity,” said Nguyen Thi Hoai Thuong, who works as a community liaison. “The interesting part is I work for the project, but I actually work for the community and with the community.”

While the wind farm is not yet online, a focus on local hiring and paying fair prices for land has already made a big difference to the community.

“I used the money from the land sale to the Dai Phong project to repair my house and invest in my cattle. Currently, my life is stable and I have not encountered any difficulties since selling the land,” said Ms. Le Thi Doan.

Powering change

The energy sector accounts for approximately 75 per cent of total global greenhouse gas emissions (GHGs). UNEP research shows that these need to be reduced dramatically and eventually eliminated to meet the goals of the Paris Agreement.

Renewable energy, in all its forms, is one of humanity’s greatest assets in the fight to limit climate change. Capacity across the globe continues to grow every year, lowering both GHGs and air pollution, but the pace of action must accelerate to hold global temperature rise to 1.5 °C this century.

“To boost growth in renewables, however, companies need to access finance,” said Rakesh  Shejwal, a Programme Management Officer at SCAF. “This is where SCAF comes in. SCAF works through private equity funds and development companies to mobilize early-stage investment low-carbon projects in developing countries.”

The 176 projects it seed financed have mobilized US $3.47 billion to build over one gigawatt of generation capacity, avoiding emissions of 4.68 million tons of carbon dioxide (CO2) equivalent each year.

But SCAF’s work isn’t just about cutting emissions. It is bringing huge benefits across the sustainable development agenda: increasing access to clean and reliable electricity and boosting communities across Asia and Africa. SCAF will be potentially creating 17,000 jobs.

This is evident in Ninh Thuan province, where the Blue Circle created both the first commercial wind power project and the first to be commissioned by a foreign private investor in Viet Nam.

Here, the Dam Nai wind farm has delivered fifteen 2.625 MW turbines, the largest in the country at the time. These will generate approximately 100 GWh per year. They will avoid over 68,000 tCO2e annually and create more than an estimated 302 temporary construction and 13 permanent operation and maintenance jobs for the local community.

Students from the local high school in Ninh Thuan Province were also given the opportunity to meet with engineers and technicians on the project, increasing their knowledge about how renewable energy works and opening up new career paths.

SCAF, through its partners, is supporting clean energy project development in the Southeast Asian region and African region. SCAF has more than a decade of experience in decarbonization and is currently poised to run till 2026.
