Solar Power’s Water Problem in the Gulf

This article is part of a series exploring regional energy cooperation in the Gulf and is published in cooperation with Istituto Affari Internazionali.

Since the inauguration of the Mohammed Bin Rashid Al Maktoum Solar Park in Dubai in 2013, the Gulf Cooperation Council (GCC) has become home to an increasing number of solar power installations. Emirati leaders have so far invested the most in large utility-scale solar in the region, but their peers in Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain have also begun to set up new solar parks in recent years.

The Arabian Peninsula’s desert landscapes might seem to be perfect for large solar power facilities like those being developed in the GCC states. Vast and largely uninhabited, the Arabian Desert gets plentiful sunshine: it receives around 3400 hours of sunshine per year, compared with averages of around 1600 hours in Germany or 2900 hours in Spain.

But solar power needs much more than desert sunshine to work. Arid landscapes present various infrastructure challenges, including high temperatures that can damage solar arrays and remoteness from established energy transmission lines. And where sunshine is most abundant, water is not.

Indeed, water scarcity is the most important limit on the grand promises of GCC governments to overhaul and decarbonise the region’s energy system. The Arabian Desert is one of the most arid places on earth, typically receiving under 4 inches (100 mm) of rain per year, and already facing near total depletion of its groundwater.

Unfortunately, today’s solar technology requires substantial amounts of water. Celebratory discussions about solar power are often illustrated with photographs of sparkling PV arrays. These solar panels are always pristine, recently cleaned arrays. Unfortunately, such a scene is a rare encounter in the Arabian Desert, where dust and blowing sand is quick to cover the solar panels and mirrors of both PV (photovoltaic) systems and CSP (concentrated solar power) systems.

Aware of desert solar’s dust problem, companies like Arizona’s First Solar and Luxembourg’s SolarCleano have promoted waterless cleaning systems. Yet these technologies are still not advanced enough to employ on a large, industrial scale. Solar technology companies based in the Gulf are also aware of this problem and have tried to engineer their own solutions. For example, Saudi Arabia’s NOMADD has designed its namesake “NO Water ​Mechanical ​Automated Dusting Device” to address the challenge of cleaning of solar panels in the Arabian Peninsula.

While robotic PV-cleaning systems are deployed in some sites today, waterless cleaning technologies are expensive and have failed to scale up beyond small, pilot projects. As a result, the GCC’s small-scale solar installations and the large-scale solar parks continue to use water to clear dust and debris from their panels. Most of that water is desalinated sea water, which is produced with a huge energy cost and substantial CO2 emissions. In this case, then, solar energy produced in the Arabian Peninsula’s desert parks is far from green—it is actually incredibly wasteful.

Renewable energy’s water footprint

The water footprint of solar power extends beyond just cleaning. Water is also used in extracting diverse minerals needed to manufacture PV cells and batteries, such as lithium, cobalt, tellurium, and gallium, as well as in the manufacturing process itself. Mining for the renewable energy sector largely takes place outside of the Arabian Peninsula, but Saudi Arabia’s new investments in mining, described as advancing global efforts to “decarbonize,” will invariably expand this water footprint in the region.

Water is integral to all modern forms of electricity generation, including fossil fuels, and nuclear, alongside renewables. Required water inputs vary by the source, in large part because the infrastructures needed to generate, store, and transmit energy all have different geographies. The solar water footprint contrasts to the water demands for coal, for example, where water is first used to extract coal from the earth, and then in power plant cooling operations like all thermoelectric power systems (coal, natural gas, and nuclear).

Proponents suggest that the water demands of renewables are a significantly lower than those of traditional fossil fuels. This is probably true. But even so, estimates from the IEA (International Energy Agency) use absolute numbers that reflect a limited proportion of renewables in the overall global energy supply mix. These estimates also tend to neglect the physical geography of renewable energy installations siting—like whether a proposed solar park is located in a desert where it is liable to dust problems that increase its water needs.

Overpromising solar to hype hydrogen

Encouraged by partners in Europe and Asia, Gulf fossil fuel producers are increasingly keen to promote hydrogen energy and state-backed efforts to develop hydrogen are now found in the UAE, Saudi Arabia, and Oman. In many cases, these projects are framed as key to transforming the region into future “green” hydrogen hubs. Creating hydrogen energy requires vast amounts of energy and for it to be “green,” this energy must come from renewables.

To date, the amount of renewable energy produced in the Arabian Peninsula is so limited that none of the impressive green hydrogen targets in the Gulf are realistic. Local programs that position the Arabian Peninsula as a new green hydrogen hub overpromise their future solar energy capacity. They overpromise solar both in the present, because the production capacity simply is not there, and also in the future, because the region’s water supplies are insufficient to deliver on local renewable energy promises. Instead, the new Gulf hydrogen programs are on track to locally lock in natural-gas generated hydrogen. Meanwhile, the water limits of solar power’s expansion are a fundamental obstacle to any future for “green” hydrogen in the region.

Just like the solar power parks that they depend on, new hydrogen energy schemes can only represent an improvement on the CO2 footprint of traditional fossil fuel energy sources if the production site decisions take water into account. If any renewable energy project’s water footprint is not carefully evaluated, then the most likely outcome will be that it turns into a big “green wash,” a convoluted mess of energy infrastructure that is built in the name of being green, but does not actually result in any CO2 reductions. And perhaps the most tragic outcome of this green theater would be if it only exacerbates local water shortfalls that then exacerbate the climate crisis, as they are met with yet more carbon-emitting desalinated seawater.

Water and energy futures

Although water is one of the most forgotten elements in today’s discussions about energy systems, the water-energy nexus has come into sharper focus recently and has been integrated in the climate talks under the UAE COP28 presidency’s Water4Climate initiative. Yet, similar to how mainstream climate change discussions are defined globally, water is often just reduced to an issue of “water security” for vulnerable populations. This is, of course, an important issue. But it is almost entirely divorced from the problem of water use and planning in the implementation of high-tech energy infrastructure around the world.

Regardless of whether oil and gas is “phased out” or “phased down,” fossil fuels are on their way out. Yet high-tech energy infrastructure, including renewables, will continue to be prioritised by political and economic leaders in the Arabian Peninsula. The question is where those infrastructures will be located.

Since the Gulf’s energy leaders want to remain central to the post-oil energy system, they are already investing in renewable energy abroad. For example, the UAE’s Masdar has stakes in solar parks, wind farms, and geothermal energy operations all across the world, including in neighbouring Gulf states like Iraq. Likewise, UAE-based AMEA Power was set up several years ago with the express purpose of investing in foreign renewable energy projects – and is growing at breakneck speed. Renewables have also been major targets for foreign investment from Saudi Arabia’s ACWA Power, which has also been the most aggressive actor in setting up hydrogen partnerships with foreign partners in Eurasia and the MENA region, including in Morocco, Uzbekistan, Kazakhstan, China, and beyond.

These future energy partnerships are already fostering regional cooperation and they will continue to do so. However, it is essential that water be at the centre of all considerations about how renewable energy infrastructures are located. In particular, if solar parks are located in places that strain water resources in a partner country—such as with growing water problems from Morocco’s Noor solar plant—then they are likely to provoke local opposition and accusations of “water grabbing” and neocolonialism.

No map can answer the question of how renewable energy landscapes should be ideally configured, because all geography is political. But decision-makers in the GCC, in neighbouring countries like Iraq and Iran, and in countries spearheading climate action, must think critically about where to locate renewable energy infrastructures. To take serious, coordinated action toward scaling renewable energy in a way that actually reduces carbon emissions, water usage must be the primary consideration.

Can Chinese Investment Bring Sunshine Back to Iran's Solar Industry?

Renewable energy has been one of the brightest sectors in the Iranian economy, achieving 70 percent growth in the last Iranian year according to official data. There are currently 85 large-scale and more than 1,850 small-scale renewable power plants feeding electricity into the national grid. The overall capacity of renewable power plants in Iran reached 637 MW this month. A further 41 large-scale power plants with a total output capacity of 431 MW are currently under construction across the country.

Overall, the sector is projected to generate 1,000 MW of clean electricity annually by 2022. This additional capacity is especially important as policymakers seek to meet rising electricity demand and prevent summer blackouts in coming years. It is also a source of export revenue. Iran has exported USD 4.1 billion worth of electricity to its neighbors over the last five years, with renewable energy a growing contributor. 

The environmental benefits are also significant. Growing use of renewable energy has saved 541 million liters of increasingly precious water and replaced the consumption of 600 million liters of fossil fuels in the past ten years.

At a smaller scale, an increasing number of farmers, struggling with a chronic shortage of water supplies, are turning to solar power generation on their farms. Farmers in Esfahan who are no longer permitted to cultivate rice are taking advantage of a 20-year government guarantee for the supply of electricity. It is estimated that over 1,000 small-scale solar power plants are now installed in farms across rural Iran.

Attractive Legal Structure

But this encouraging growth is now in doubt. The Trump administration’s unilateral withdrawal from the JCPOA nuclear deal has brought economic uncertainty for local investors and made foreign direct investment increasingly difficult.

Mohammad Sadegh Zadeh, deputy minister of energy and head of the Renewable Energy and Energy Efficiency Organization (SATBA), recently announced that the sector has attracted IRR 100 trillion (USD 940 million) from local private-sector investors over the last two years. Foreign investment has been even more important, contributing USD 1.7 billion, nearly 70 percent of total investment since President Rouhani took the office in 2013.

Foreign investors completed several projects in this period. These include a 20 MW solar farm in Mahan backed by Swiss investors, five German-backed solar power plants in Hamedan with a total capacity of 38.5 MW, the first phase of a 50 MW solar plant backed by Italian investors, two Greek-backed 10 MW solar farms in Yazd and Isfahan; a 10 MW solar farm in Tehran backed by French investors, as well as further projects developed by Turkish, Austrian and Swedish companies.

However, Trump’s unilateral exit from the 2015 nuclear agreement with Iran, and his decision to re-impose sanctions against the country, pose a new threat toward foreign investments. The effects are already being felt in the sector.

British developer Quercus, which was set to develop Middle East’s largest solar power plant in Iran, decided to halt its work in the country, while other developers are reportedly re-thinking their plans for their future activities in the country, especially as even routine banking transactions become more difficult.

The depreciation of the rial and the tight foreign exchange market also pose a challenge for developers and make the incentives in Iran’s electricity market less attractive, according to Shahriar Sabet, a London-based renewable energy investor.

“Iran has created an attractive legal structure for investors which includes the power purchase agreement and FIPPA [Foreign Investment Promotion and Protection Act]... Also the feed-in-tariff (FiT) is an important factor as it remains one of the highest paid in the world,” Sabet says.

“Although with depreciation in rial, the FiT has dropped significantly but under FIPPA investors can still repatriate their capital and revenue under official exchange rate”, Sabet explains. “ The government is working hard to continue allocating the official exchange rate to the sector for the repatriation of revenues which in this climate is another positive sign,”

Sabet also emphsises that “institutionally, Iran has tried very hard to prioritize the renewable energy sector, with coordination between the Ministry of Energy, Ministry of Economy, SATBA, and local grid companies, to create a very supportive platform with clear procedures for foreign investment.”

“The current conditions, internally and internationally, have adverse effects on the market. However if Iran maintains its current structures, our view is that it is a market to invest in. I do believe those who are on the ground should not abandon their projects and confront the headwinds and new investors should also explore ways to enter this highly attractive and relatively stable sector in Iran,” Sabet insists.

The Need for Government Guarantees

But the government still has options to save the sector. Ehsan Imani, an expert in feasibility studies of renewable power plants, believes that the government needs to focus on three major issues to keep foreigners interested in the market.

“Payment guarantees could be the very first and the most effective tool to revive the market’s attraction. The feed-in-tarrif also should remain high although it is still higher than some other countries even after drops in recent months the. Investors cannot easily ignore Iran if the government reconsider its pricing policy and issue payment guarantees,” he explains.

Sabet agrees on the need for guarantees: “Issuing such guarantees for smaller projects will create more confidence and boost the flow of investment albeit at smaller scale.”

Regular settlement is also of high importance from Imani's point of view: “Late payments naturally could change the minds of those investors who are plans to enter the market.”

Until the recent currency crisis, SATBA had reportedly managed to meet its payment requirements on time. The Central Bank of Iran has offered to make payments in yuan instead of euros, a move not favored by European investors.

The Sun Rises in the East

As with other sectors of Iran’s economy, the withdrawal of European investors from Iran’s solar industry may mean that “Chinese money turns out to be the best available option while other investors have to miss the opportunity,” as Sabet puts it.

Chinese investors face fewer barriers to investment according to Imani, “They face no serious restrictions to sell facilities to Iran, and payments are easy to make–[even if it is paid in yuan].”

This is especially true because Chinese companies lead the world in the manufacturing of solar panels. Because the panels merely need to be installed in Iran, up to 80 percent of the total investment cost for a solar project in Iran can be paid directly to Chinese panel suppliers or plant designers in local currency.

Recent developments in the market suggest a growing role for Chinese investors. In July, Yazd province officials signed an agreement with a partnership of Chinese and Italian firms for the development of a transformative 500-1,000 MW of solar projects. The agreement includes installing 20,000 small 5 KW power plants in residential units across the province.

The provincial government in Qom province  signed an MOU with a major Chinese company to develop of a 30 MW power plant in the central province. Chinese firms have also reportedly reached agreements for development of large solar power plants and the local manufacturing of solar panels in Fars, Zanjan, North Khorasan and East Azarbaijan provinces.

For Iran’s solar sector, the sun may be setting in the West. But it may rise again in the East.

Extention of Key Incentive Scheme Boosts Iran's Renewable Energy Market

Since the lifting of sanctions, Iran’s renewable market has emerged as an exciting destination for international green energy developers and investors. Growth can largely be attributed to a generous Feed-in-Tariffs (FiTs) scheme and the government’s continued effort to promote policies that, in combination, aim to strike the right balance between promoting Iran’s renewable market, removing barriers to project deployment, and building the technical capacities of the domestic industry.  By looking at some of the recent but important developments in Iran’s renewable energy (RE) market, including the nature of government policies, it becomes clear that the Rouhani administration has set a path for growth enabled by international investment.  

Iran’s generous program of green subsidies has been the key determinant of the attractiveness of its renewable market, and with the government’s recent decision to maintain its current FiTs for another 12 months, the market is set to shift into a higher-gear. The extension of the FiTs scheme, which was delivered through a decree signed by the Minister of Energy in mid-March 2017, demonstrated the continued commitment of the government in sustaining the momentum of its favorable renewable energy investment landscape among many of its regional and international competitors. The consistency in the nature of Iran’s renewable policies in the last three years is by extension, a major confidence-building measure for developers and investors, whose interest in a given market is not cultivated by generous FiTs alone, but also by stable and predictable policy environment.

Interestingly, the recent extension Iran’s FiTs scheme comes at a time when in most of other markets across the globe, governments are either reducing, halting or terminating their FiTs schemes all together. This has been a major cause of concern for green developers and investors with huge vested interest in those markets. With a reduction in government incentives and flattened demand in the European market, green developers and investors are now eagerly looking into opportunities in other attractive markets. Iran comes at the top of the list.

Opportunities and Limits of Feed-in-Tariffs

The extension of Iran’s FiTs scheme presents a window of opportunity that will not be around forever, and so the countdown has already begun for developers to take advantage of the existing rates by signing their Power Purchase Agreements (PPAs) with Iran’s Renewable Energy Organization (SUNA) prior to March 2018. In light of this, it is projected that this year SUNA will expand its pipeline of renewable projects to be developed by international developers in partnership with local partners.

Currently, Iran’s FiTs scheme stipulates a 20-year PPA framework that supports a series of 13 renewable plants. The structure of the scheme is deliberately designed to increase the solar and wind capacities of the country, while also encourage procurement of smaller-scale projects by offering higher margin of profit for systems under 10MW and 30MW capacities. The reason behind this policy is twofold. On the one hand, it allows an experimental approach, where the impact of the initial projects that are pending construction and connection in this fledgling market can be assessed, and on other hand, it enables for the competence and commitment of developers to be evaluated in smaller projects prior to issuing further licenses for larger-scale developments. For the most capable developers, Iran’s FiTs system and structure simply means a strategy of portfolio aggregation—that is, building smaller projects that can be aggregated at a later stage. Therefore, many of renewable projects that will mushroom across different regions of the country in the next 24 months will consist of solar photovoltaic plants with 10MW to 30MW of capacity.

Nevertheless, the success and growth of Iran’s RE market cannot not rest on its generous FiTs scheme alone. For example, rival renewable markets, such as UAE, Jordan and Egypt, are currently developing and deploying projects on a much larger-scale than Iran without even considering the need to offer a generous FiTs scheme. For example, the launch of Dubai’s recent large-scale 200MW solar project in March, which was implemented at a record-low bid of 5.6 cents per kilowatt-hour, was product of a competitive RE tendering scheme, which is an alternative means of engaging developers.

The rapid pace of progress in the region’s RE markets, has made Iranian authorities ever more conscious that in parallel to providing FiTs, they need to institute and maintain multiple complementary mechanisms, such as competitive bidding tenders. Taking this in mind, the recent announcement of Yazd Regional Electricity Company for its plans to hold Iran’s first RE tender on the development of a 150MW utility-scale solar project is precisely aligned with this new emerging strategy of Iran—that is, to maintain its current FiTs scheme for broadly incentivizing development projects on smaller-scale, while phase in competitive bidding tenders as a new complementary measure to support larger-scale projects.

Project Deployment Mechanisms

In parallel to government’s effort to incentivize this market in the last two years, SUNA has also been hard at work in addressing deficiencies in regulations, removing barriers-to-entry, and setting a viable and functioning mechanism for project procurement and development. Designing an effective implementation framework, is in many respects the most challenging part of the puzzle for new emerging renewable markets, such as Iran. It requires a significant deal of coordination between various bureaucracies and organizations, followed by a synchronization of relevant policies and regulatory frameworks that enable project procurement and development. The good news is that the Iranian RE market has made great strides in this regard. The successful launch of the 14MW Hamedan solar park in February 2017, followed with the upcoming launch of Esfahan 10MW solar park, would not have been possible without a functioning project development mechanisms.

The achievements of SUNA in responding to many of technical and non-technical impediments of project implementation framework and regulation deficiencies means that the organization can now expand its activities into other important areas, such as more active investment promotion activities.. This includes establishing and developing new synergies and facilitating dialogue with international RE bodies for learning best practises in areas of policy, technology and financial resources, while also engaging with both local and international financial investors to provide the necessary project finance facilities. The recent delegations from the International Renewable Energy Agency (IRENA) and the Norwegian Export Credit Guarantee Agency to Iran to hold meetings with SUNA reflect the increased communication and engagement of this organization with international stakeholders and bodies.

Building Technical Capacity

Support for renewable energy will not only bring numerous environmental benefits, but will also have significant economic yields for the country. The RE sector can important source of job growth should investment support local capabilities and infrastructure. Iran’s renewable market, despite in its infancy, has already inspired countless entrepreneurs to set up localized businesses in the value chain of renewable power generation and development solutions.

This has not gone unnoticed by the government, which has particularly designed its FiTs scheme in order to foster technical capacity within the industry. The program supports local businesses and entrepreneurs active in this field by allocating a premium of up to 30% on base FiTs rates to those projects that utilize locally-produced content. This premium is attractive enough to encourage international developers to maximize integration of domestically produced technologies, or to explore new local manufacturing of key components.

The next generation of Iranian electrical engineers and technicians has already demonstrated resilience, technical expertise and an entrepreneurial-mindset by not only creating and supporting the value chain of electricity generation of the country, but also exporting their services, equipment, and technologies to the regional markets. To demonstrate, Iran’s power industry, exported over USD 3 billion in electric engineering services and goods to the regional market last year. Aside from supportive policies, the long-term potential to use Iran as a launchpad for regional expansion, sets the country's renewable energy market apart from its regional rivals. Investors are beginning to take note.

Renewable Iran: Creating the Energy Network of the Future

The global energy industry continues to find greater value in efficiency and clean technology, with a rapidly growing reliance on renewable energy. For Iran and the Middle East however, oil and gas have hardly been challenged as the dominant industry forces. But now that Iran prepares to once again open doors to the international business community, we must ask if renewables can, or even should, play a greater role in the future of Iran’s energy sector.

So, what’s the problem?

Iran is the country with the world’s largest conventional gas reserves and is the world’s third largest producer of natural gas - behind the US and Russia. Given these abundant reserves and production, you have to question why has a country of Iran’s population been a consistent net importer of natural gas during the last decade. The answer is Iran has very high per capita consumption of gas and other fossil fuels, with much of it going into power generation. In 2014, Iran burned 50 billion cubic meters of gas for power generation: that is more than in the UK, Germany, Italy, and France combined. In fact, in 2013, Iran consumed more gas than China, and was the 8th biggest energy consumer in the world, despite being the 32nd largest economy (World Bank) and the 17th most populated country. 

Moreover, according to the International Energy Agency (IEA), Iran is among the top ten global emitters of CO2. Iran is the top emitter in the Middle East and accounts for almost a third of the region’s total carbon emissions. Fossil fuels account for almost 98% of Iran’s total primary energy consumption.

Of the 70 gigawatts (GW) of power generation capacity installed in the country, only around 11 GW are low carbon sources with most of that hydro (10 GW) while 1 GW is nuclear, and 0.1 GW is either solar or wind. The rest is largely old, inefficient, and polluting fossil fuel power plants burning either fuel oil or natural gas. According to Iran’s Ministry of Energy, over the past decade electricity demand has grown by almost 6% annually, and is expected to grow by at least 2% - 4% through the end of the decade. There are now more than 30 million grid connected clients in Iran, compared to less than 20 million only ten years ago. 

So, Iran faces the problem, how can it meet this rapidly growing electricity demand while reducing its consumption of gas and fuel oil to eliminate imports (and facilitate exports), reducing carbon emissions to more average global per capita levels, effectively addressing the challenging air quality issues, and still attracting foreign investment and new technology?

The Role of Renewables

The answer is likely to be found in a combination of a modernisation of its power generation capacity, greater energy efficiency, and much greater reliance on renewable forms of generation.

In terms of renewables, Iran is naturally blessed with very good solar and wind conditions. Iran receives around 300 days of sunshine each year, compared to less than 64 days in Germany, the world’s leader in solar power with almost 25% of the global solar power capacity. The Global Wind Energy Council stated that some of Iran’s mountainous areas in the west and northeast have unique wind corridors that have plenty of potential for renewable generation.

The Iranian government is starting to get that renewables should now be an important part of the country’s energy strategy. In early 2014, Iran’s Ministry of Energy unveiled its plans for adding some 5 GW of renewable power capacity, mostly wind, to the country’s power fleet by 2018. Since the beginning of 2014, construction for around 400 MW of renewable capacity has started, and contracts for more than 500 MW have been awarded. The Iranian government increased its budget for renewable energy by more than 400% last year to around $60 million; although still small, the growth is going in the right direction.

Iran has also adopted a number of new policies towards renewable expansion, using similar policies to many Western European countries and opening up the sector to foreign investors. The Ministry of Energy has set up the Renewable Energy Organization (SUNA) that will administer these policies that include a feed-in-tariff scheme, under which the Ministry of Energy will buy the power generated from renewable sources at set tariffs for a 20 year period. At the set energy tariffs, investors are expect to be able to recover a full return on their investment in around four years of operations. In addition, the Iranian government is committed to providing up to 50% of the cost of installing residential solar panels, and to installing solar panels in public buildings. 

Another spur to renewables growth comes from the calls to introduce a carbon emissions trading scheme. In February 2014, Iran announced that it is planning to introduce an emission trading scheme (ETS) that would cover its power sector. Although little information is available about the structure of the scheme, it is certain that such ETS's are designed to discourage the use of inefficient fossil fuel burning power plants. The emissions cap will eventually increase the power generation costs for inefficient power plants and will further support the growth of clean energy and renewables.

With all the challenges Iran is facing, renewable energy offers a unique sustainable solution for Iran to fundamentally overcome these issues, while providing significant investment opportunities for international investors, and also boosting the overall sustainability of economic growth.
