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

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:
- Taxes are fixed in an efficient way, in order to distort as least as possible consumers and producers decisions
- Consumption is efficient, both through taxes and regulated tariffs
- 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.

Seeing Japan – Indonesia Collaboration in Energy Transition Cooperation

Holding the G7 presidency, Japan is increasingly active in establishing relations with several countries. One of them is Indonesia. The relations that have existed so far between Indonesia and Japan are widely visible on the surface. One of them is in the energy transition sector. Indonesia is in need of a large investment to achieve net zero emissions in 2060. An investment of more than 500 million US dollars is needed to make this happen. This is indicated by the great effort to reduce energy that uses fossil fuels (coal, oil and gas) in people’s lives. Including efforts from Japan to cooperate with Indonesia or vice versa in achieving net zero emissions.
Abundant Natural Resources: A Privilege for Indonesia
The abundance of natural resources owned by Indonesia is an important point for the continuation of cooperation between Japan and Indonesia. Natural resources such as hydrogen, geothermal are important values to be further developed into renewable energy. This is a breath of fresh air for Indonesia, which is trying to achieve net zero emissions by 2060.
Replacing fossil fuels such as coal, oil and gas to renewable energy requires extra effort, Indonesia which is rich in energy resources requires a lot of money in terms of exploration of natural resources. renewable energy resources, such as hydrogen, geothermal. renewable in Indonesia. One of them is through a funding scheme through the Asian Zero Emission Community (AZEC). Through this funding, Japan, which is known to be very generous in helping developing countries in terms of energy, is expected to be able to bring change to the renewable energy transition in a country rich in energy resources, Indonesia. This transition certainly requires a short and gradual process.
State Electricity Company of Indonesia abbreviated as PLN, states that dependence on new coal will decrease in 2030. This is due to the presence of power plants from renewable energies such as geothermal, solar, hydrogen and nuclear and wind (Kompas, 2023).
Japan’s Investment to Indonesia
Indonesia, with all its abundance of energy resources, is considered capable of developing an energy transition. The development of electricity from geothermal, water and biomass are the main sector. This was conveyed by the Government of Japan through Deputy for International Affairs, Ministry of Economy and Industrial Development of Japan Izuru Kobayashi. He stated that his party was ready to assist Indonesia in achieving net zero emissions in 2060 with an environmentally friendly funding and technology assistance scheme.
The above was also supported by another Japanese party, namely from Sumitomo Mitsui Banking Corporation (SMBC). Quoting from IJ Global, SMBC has financial assistance to Asia Pacific countries for clean energy projects through Mitsubishi UFJ Financial Group of US$1.5 billion, Sumitomo Mitsui Financial Group of US$1.2 billion, and Mizuho Financial Group of US$1.2 billion. 1 billion US dollars. In Indonesia alone, as of September 2022, SMBC had invested US$221 million.
Various forms of support by Japan as donors and companions for Indonesia to develop renewable energy should be appreciated. According to the author opinion, this is a challenge for the Government of Indonesia and all of stakeholders inside, to create an investment environment that is safe, good and useful for Indonesia’s future. The use of fossil fuels such as coal for power generation needs to be slowly substituted using renewable energy. The Jokowi administration’s policy of subsidizing electric vehicles for the public can be an entry point for the continuation of Indonesia-Japan collaboration in realizing the energy transition.

The Maneuvering Of Gas Commodities As Securitization Of Russia’s Geopolitical Position

Authors: Luky Yusgiantoro and Tri Bagus Prabowo
In 2012, the Yakutia-Khabarovsk-Vladivostok gas pipeline project was redeveloped under The Power of Siberia (News Ykt, 2012). Putin legalized Gazprom (contractors: Gazprom Transgaz Tomsk). The idea named “Power of Siberia” represents the power of gas pipelines to shape and influence Russia’s geopolitical and geoeconomic situation. A new identity will be launched, conveying the Yakutia-Khabarovsk-Vladivostok gas pipeline and gaining international prominence. The Power of Siberia project is an integrated form of GTS (Gas Transmission System) that will bring the Irkutsk gas region in the fertile eastern part of Russia to the Far East and China. The pipeline location is located in the “Far East,” incredibly close to the border with China, and generally in the Asia-Pacific region. Initially, this gas pipeline was built to facilitate gas trade with China and reduce China’s dependence on coal (Pipeline Journal, 2022). What is the value of this project for both countries to become global concerns?
Furthermore, they have the ability or range to carry gas communications for approximately 4000 km. Due to its geographical proximity and shared economic interests, China is Russia’s most progressive partner in terms of a multifaceted regional and international strategy. Russia and China are known as close partners. The aftermath of Russia’s political alliance was to regain global power, status, and influence lost after the collapse of the Union of Soviet Socialist Republics in 1991, which was the driving force behind the end of the Cold War (Oualaalou, 2021 ). Russia has articulated a vision of rebuilding its global reputation using energy, military might, intelligence, and diplomacy. Russia wants to play a crucial role in the global multipolar system because the West rejects Russia’s vision for a new geopolitical order. They saw many important events related to Russia’s moves in the international order, including its response to the actions of the North Atlantic Treaty Organization (NATO) to try to dominate the nations of the world. The former Soviet Union (East), the failures in the Middle East, the annexation of Crimea, and one of Moscow’s recent invasions of Ukraine mark the military as a turning point in Russian geopolitical politics, especially during the Putin era. Russia has three strategic initiative points, including the ability to deploy and interconnect the means (intelligence, diplomacy, military, cyber, and energy) to gain influence and extend Russia’s global footprint. There is.
Moreover, the Fallacies and Western Ties strategy contradicts America First foreign policy tenets (unipolar) and impulsive decisions as a security threat. Russia wants to maintain its lack of regional interests in certain Baltic states (those still under Russian control) and the Balkans (Cooley, 2017). The Balkans (Albania, Bulgaria, Bosnia and Herzegovina, Croatia, Kosovo, Montenegro, North Macedonia, Romania, Slovenia, and Serbia) have been the cornerstones of great power rivalry for centuries. NATO (North Atlantic Treaty Organization) and the EU (European Union) used the momentum of Yugoslavia’s dissolution in the 1990s to integrate the Balkans as geopolitical hotspots on the Western Front (European Policy). War analysts say the ongoing Ukraine conflict is a way for Russia to raise its stakes in the Balkans and reassert its regional influence (McBride, 2022).
In 2020, natural gas will still be the world’s third-largest primary energy requirement for the global community. Even though the COVID-19 pandemic began in 2019, demand for natural gas increased by 5.3% to 4 trillion cubic meters (TCM) in 2021 (BP, 2022). In 2021, Russia’s total natural gas production will be 701.7 billion cubic meters, the second largest globally, contributing to the strong demand in the global energy market. Russia is essential in the natural gas market (Sonnichsen, 2022). The climate crisis is the most obvious obstacle in the global gas market model. It originates from burning carbon with materials derived from fossil fuels such as oil, natural gas, and coal. However, natural gas is acceptable during the energy transition as it burns the least carbon dioxide (CO2) and pollutants of these three substances (EIA, 2022). It is easier than supplying a gas infrastructure that does not provide infrastructure. Operationally, it is optimal. Talks about climate protection, the climate crisis, and the energy transition are being shaped by Western countries as a way of highlighting Europe’s dependence on gas from Russia, which is geographically accessible and still has gas in other gas reserves. The decision to stop sourcing natural gas from Russia continues to cause European controversy. The pipeline network actively built between Russia and Europe is an essential aspect of why this relationship is used as a tool for Russia to apply pressure—on territorial Europe. Europe uses a climate scenario, and Russia uses a gas-dependent scenario. Efficiency and effectiveness will not be achieved if Europe suddenly has to look for other reserves or switch entirely to this energy mix. Then, with Russia’s eloquence in exploiting the situation and the status quo, natural gas pipelines were used as a form of Russian energy diplomacy to dominate its (European) neighbors. Recognizing that the Western natural gas market is no longer preconditioned, moving target consumers to the Asia-Pacific region is one of the most effective energy plans for Russia’s fossil fuel expansion.
Siberia’s first electricity will cost 770 billion rubles, and the investment in gas production will cost 430 billion rubles. The 1,400 mm natural gas pipeline capacity will increase to 61 billion cubic meters (2.2 trillion cubic feet) of natural gas annually. The pipeline lets the world see natural gas as one of the fossil fuels and does not pollute the air with the carbon and other substances of the climate crisis. , through the capital Beijing and down to Shanghai. According to state media, the intermediate phase will go online in December 2020, with the final southern section expected to start delivering gas in 2025 (Cheng, 2022). Through this agreement, Russia aims to extend its power beyond Mongolia into Siberia 2 in 2030 (IEA, 2022). Conditions for Europe to get 40% of natural gas from Russian pipelines. Germany, in particular, sources about half of its natural gas from Russia (Baldwin, 2022). Despite international media reports of embargoes and sanctions, the crisis has hit Europe hard. Europe must adapt its economic policies to politically justified policies and coordinate them with each other. However, this is a geopolitical struggle, and we must ensure that the country retains its absolute superiority. Russia chooses to invest in and plan for natural gas markets in regions that require or depend on natural gas in the energy sector, i.e., Asia-Pacific via China. China, influencing the Belt and Road Initiative (BRI) plan, is reshaping the geoeconomic position of Russia’s Siberia 1 and Siberia 2 power markets (Lukin, 2021). “Geopolitics is all about leverage” is one of Thomas Friedman’s influential geopolitical maxims. If a country cannot expand its influence, it remains a loser. Nevertheless, Russia is far from this analogy, as mentioned earlier. Russia continues to secure its geopolitical position. It is the embodiment of growing confidence in the reliability of natural gas. Russia still wants to become a major player in natural gas.

Remapping the EU’s Energy Partners to Ensure Energy Security and Diversification

Energy security has been a buzz word in Brussels for a few decades but since Russia’s invasion of Ukraine, followed by sanctions, Russian gas cut-off and physical destruction of North Stream pipelines, forecasts on strained EU energy production due to drought, the stakes have gotten much higher. This was confirmed on March 10th by a joint statement by the US President Joe Biden and European Commission President Ursula von der Leyen, reiterating both parties’ determination to “build clean energy economies and industrial bases”, including clean hydrogen and continue to work together “to advance energy security and sustainability in Europe by diversifying sources, lowering energy consumption, and reducing Europe’s dependence on fossil fuels”.
Last week, the EU energy chief Kadri Simson encouraged all Member States and all companies to “stop buying Russian LNG, and not to sign any new gas contracts with Russia. The EU has pledged to quit Russian fossil fuels by 2027 and replaced around two-thirds of Russian gas last year.
In this context, the Southern Gas Corridor (SGC), delivering Azerbaijani gas through (Trans-Anatolian Pipeline) TANAP and Trans-Adriatic Pipeline (TAP) to the EU, plays a key role in current diversification efforts. The EU increased gas imports via pipelines from Azerbaijan from 8.1 bcm to 11.4 bcm last year. Only two years after its completion, the expansion of the Corridor seems to be likely as the EU and Azerbaijan stroke a deal in July 2021 to double the volume of gas delivery to 20 bcm by 2027 in addition to plans to tap into Azerbaijan’s renewables potential, such as offshore wind and green hydrogen. While encouraging Azerbaijan’s accession to the Global Methane Pledge, the deal aims at collecting natural gas that would otherwise be vented, flared, or released into the atmosphere.
With the opening of the interconnector Greece-Bulgaria (IGB), at least 11.6 bcm of gas is expected to be delivered from Azerbaijan to the EU this year. The IGB has been dubbed as a game-changer for the EU’s energy security, especially as it enabled supplies to Bulgaria and Romania. A Memorandum of Understanding on gas supplies between Azerbaijan and Hungary was also signed this year, which shows that more interconnectors will be needed in the EU if TANAP would be expanded from 16 to 32 bcm and TAP from 10 to 20 bcm.
Moreover, investments will be needed to increase gas production in existing and new gas fields (Shah Deniz, Azeri Chiraq Guneshli, Absheron, Shafaq-Asiman, Umid-Babek, etc.), especially considering growing energy demand in Azerbaijan and its neighbours. Since the Russia-Ukraine war, 10 European countries turned to Azerbaijan to increase existing supplies or to secure new supplies. To meet such growing demands, Azerbaijan is poised to increase cooperation with neighbouring states, such as Turkmenistan, which is home to 50 trillion cubic metres of gas reserves – the world’s 4th largest reserves.
Following the Azerbaijani-Turkmen decision to jointly develop the formerly disputed Dostluq gas field, a trilateral swap deal between Iran, Azerbaijan, and Turkmenistan, and the 2018 Convention on the status of the Caspian Sea by all the littoral states; Azerbaijan, Turkmenistan, and Turkey stated that they were looking “to form a coordinated and multi-option system for delivering energy resources to global markets” on December 14th last year.
These developments could be harbingers of a new Trans-Caspian Gas Pipeline (TCGP), a 180-mile under-sea pipeline that could be integrated into the SGC. Labelled as an EU Project of Common Interest, which could also be eligible for funding under the 2019 US European Energy Security and Diversification Act, this strategic under-sea pipeline project could bring an end to the EU’s energy crisis by securing a cheap source of natural gas, whose price is independent of LNG prices while counterbalancing Chinese, Russian and Iranian influence in Central Asia and beyond. On the other hand, Azerbaijan began the transit of oil from Kazakhstan this year in addition to Turkmenistan, which highlights the potential to use the Middle Corridor for hydrocarbons.
During the 9th Southern Gas Corridor Advisory Council Ministerial Meeting and 1st Green Energy Advisory Council Ministerial Meeting in Baku in February, EU Energy Commissioner Kadri Simson stated “Azerbaijan can potentially become the exporter of renewables and hydrogen to the EU”. At the end of last year Azerbaijan, Georgia, Romania, and Hungary agreed to establish a green corridor to supply the EU with around four gigawatts of electricity generated by windfarms in Azerbaijan with the support of the European Commission.
Over the last several months, Azerbaijan signed documents that will provide investments to create 22 gigawatts of renewable sources of energy, both onshore and offshore. In April 2021, the World Bank started funding the offshore wind development in Azerbaijan, which has a potential of 157 GW. In addition to the Caspian Sea, which ranks second in world for its wind energy potential, Azerbaijan has an estimated 27GW in wind and solar power onshore.The current construction of wind and solar plants in Alat (230 MW), Khizi and Absheron (240 MW) and Jabrayil (240 MW) as well as new investment plans, including in Nakhchivan Autonomous Republic, are expected to further boost renewables production in the Caspian state all by living up to its vast green potential. While the country, with a population of 10 million, accounts for only 0.15% of total global greenhouse gas emissions, it defines green growth as a key priority for 2030. The EU supports the implementation of Baku’s Paris Agreement commitments through the EU4Climate initiative.
The Russia-Ukraine war may create a window opportunity for the EU to engage in concrete actions rather than high-flying buzzwords, pushing the bloc to do more strategic and visionary planning regarding future projects linked to its energy security, such as TCGP, and finally diversify away from Russian energy sources for good. Azerbaijan has proved to be a stable partner in these challenging times, which manifested the vulnerability of certain EU states against Russian economic and political pressure due to Gazprom’s immense infiltration of their gas markets for the past several decades. Now it’s the time to play fair game by a new playbook and to remap the European energy partners while investing in a stable, predictable, affordable, and sustainable energy future for the EU.
