South Africa: Clearing the Air with Renewable Energy

386views

South African ailing energy sector seems to have found a new lease of life in clean energy. In 2012, South Africa witnessed investment of $5.5 billion in new renewable energy projects, leaving behind some well-known usual suspects such as Brazil, France, and Spain. With the local government looking at renewable energy as a long-term answer to the country’s energy problems, we evaluate the scope for private sector involvement in developing South Africa’s energy infrastructure.

In March 2013, Eskom, the national electricity provider in South Africa, warned about the possibility of power outages during the coming winter season. As soon as the news spread, millions of South Africans were left reflecting on the energy crisis of 2008, which brought the mining and industry sectors, and thereby, the economy, to a halt.

Increasing winter demand and planned electricity network maintenance are putting pressure on the power system. In May this year, long before the peak winter season, South African power system capacity exceeded demand by just 0.17% (let’s just point out that the recommended reserve margin for a power system is 10-15%). With consumption expected to increase further during winter (June and July), Eskom will be forced to look at extreme measures to prevent scenarios similar to those of 2008. Some of such measures include power buy-backs from large consumers, and triggering of ‘interruption clauses’ included in contracts, through which Eskom can cut supply to consumers in case of tight supply situations, in return for discounts.

While these measures could help deal with the short-term spike in demand this year, the South African government is looking for alternatives to achieve long term sustainability of the country’s energy sector. Investment in clean energy (particularly renewable technologies such as wind and solar) is one of the possible solutions contributing to solving the country’s energy supply problem. While achieving energy sustainability, clean energy investments will also help South Africa adhere to its commitment to achieve a 42% cut in carbon emissions between 2011 and 2025, by reducing dependence on coal for power generation. Furthermore, renewable energy projects can come online on a shorter horizon compared with coal and nuclear power plants.

Let’s focus on clean energy

According to a 2013 report published by Bloomberg New Energy Finance, South Africa stood 9th in the world with US$5.5 billion worth of new clean energy investments in 2012 (a whopping 20,563% growth over 2011). Majority of this investment (US$4.3 billion) has gone into developing solar photovoltaic (PV) technology based power plants, with the remaining being spread across wind, concentrated solar plants, landfill, biomass and biogas, and hydro-projects.

The onset of clean energy investment projects in South Africa is correlated with the introduction of the Integrated Resource Plan (IRP) in 2010, as well as Department of Energy’s Renewable Energy Independent Power Producers Procurement (REIPPP) program in 2011. As a part of the 2010 IRP, South African government outlined its plans to increase electricity generation capacity by additional 18,500 MW by 2030. About 42% of this additional capacity is envisaged to be generated through renewable energy technologies.

Introduction of REIPPP program in 2011 facilitated private sector’s involvement in electricity generation. Through this program, the government plans to procure 3,725 MW of renewable energy from independent power producers by 2016. A significant focus has been laid on procuring power generated through onshore wind and solar PV technologies. The REIPPP program sets up a bidding system through which independent power producers can bid for power generation allocations. Electricity thus generated is purchased by Eskom on a 20-year Power Purchase Agreements (PPAs). The tariff for purchasing electricity is decided through a bidding process. Some independent producers cashed on the first mover advantage, and received tariffs as high as R2.6/KWh ($0.26/KWh) during the first phase of bidding in 2011 (more than Eskom’s electricity price). With increasing competition, these tariffs have fallen in the successive bidding rounds to as low as R0.89/KWh ($0.09/KWh).

Private sector holds the key

One possible mode of involvement is continued private sector participation in the REIPPP program, selling the generated electricity to Eskom at rates agreed in the PPAs. However, several independent power producers (IPPs) have raised concern about the attractiveness of such a system, where only a single buyer (Eskom) is present in the market.

IPPs feel that lack of certainty about feed-in-tariff structures and a single buyer model are likely to deter large scale investments from the private sector. In 2012, the South African Independent Power Producers Association put forward a proposal to set up an independent grid to challenge Eskom’s dominance of the transmission (grid) network.

In March 2013, the South African government passed the Independent System and Market Operator (ISMO) Bill, which will create an independent entity by 2014, to manage procurement of energy from Eskom’s power generation business and independent power producers. Establishing an independently operated power grid would encourage competition in the power generation sector while keeping a lid on prices.

Another possible form of investments could be in the shape of independent (off-grid) solar/wind power projects by large enterprises (particularly in mining sector) to meet part of their internal demand. Industries could reap several benefits from these independent projects. Benefits of a solar power project could include:

Several large energy consumers are required to operate diesel generators to meet the surplus demand from their operations. Even though the current cost of producing solar energy is higher than what is procured from Eskom, the cost is lower than that of electricity produced through diesel generators. In the short-term, solar energy projects could replace generators, as an additional input source of energy
The national energy regulator (NERSA) recently approved an annual 8% hike in electricity tariffs charged by Eskom till 2018. With price of solar PV panels expected to decline further, the cost of solar energy production could even be lower than Eskom’s prices 5-6 years down the line
Furthermore, solar power plants have an effective life of 25-30 years, greater than the typical 20 year PPAs offered by Eskom. Independent projects enable more efficient utilization of electricity generation capacity over a longer horizon, compared with the REIPPP program

Foreign investors also to step in

With the removal of subsidies on renewable power in several European countries, South Africa becomes an ideal investment location for both foreign renewable energy developers and infrastructure financing organizations.

Participation of foreign firms in the REIPPP program has increased in subsequent bidding phases. Working as a part of a consortia, several foreign developers, such as Abengoa (Spain), Gestamp Wind (Spain), SolarReserve (USA), and Chint Solar (China), have already won bids for setting up power projects, working in partnership with local developers and BBBEE partners.

International financial institutions, such as European Investment Bank and IFC (member of the World Bank Group) have also invested in several renewable energy projects being undertaken by international developers in South Africa. In 2012, European Investment Bank agreed to provide €50million ($64.9 million) for the Khi Solar One Project being undertaken by Abengoa.

So is the energy sector out of the woods?

With a power crunch looming, the mining and industry sector companies are left searching for options to keep their operations running, or risk large-scale shut-downs during the winter season. With the declining cost of setting up and generating renewable power, investment in renewable energy projects could be a sensible option to achieve sustainability of power supply, over both short and long-term.

Setting up of an independent transmission company will go a long way in reducing Eskom’s dominance over the electricity networks, urging more private sector participation in the REIPPP program. But, is this enough? Will there be further deregulation/liberalization of the renewable power generation sector to additionally boost competition in the market? The fate of private sector investments hinges on government’s willingness to risk its control over probably the most important utility system.

Will Shale Gas Solve Our Fuel Needs for the Future?

366views

At first glance, shale gas might look too good to be true: large untapped natural gas resources present on virtually every continent. Abundant supplies of relatively clean energy allowing for lower overall energy prices and reduced dependence on non-renewable resources such as coal and crude oil. However, despite this huge potential, the shale gas revolution has remained largely limited to the USA till now. Concerns over the extraction technology and its potentially negative impact on the environment have hampered shale gas development in Europe and Asia on a commercial scale. However, increasing energy import bills, need for energy security, potential profits and political uncertainty in the Middle East are causing many countries to rethink their stand on shale gas extraction development.

How Large Are Shale Gas Reserves And Where Are They Being Developed?

An estimation of shale gas potential conducted by the US Energy Information Administration (EIA) in 2009 pegs the total technically recoverable shale gas reserves in 32 countries (for which data has been established) to 6,622 Trillion Cubic Feet (Tcf). This increases the world’s total recoverable gas reserves, both conventional and unconventional, by 40% to 22,622 Tcf.

Continent	Shale Gas Reserves and Development
North America	Technically Recoverable Reserves: 1,931 Tcf Till now, almost whole commercial shale gas development has taken place in the USA. In 2010, shale gas accounted for 20% of the total US natural gas supply, up from 1% in 2000. In Canada, several large scale shale projects are in various stages of assessment and development. Despite potential reserves, little or no shale gas exploration activity has been reported Mexico primarily due to regulatory delays and lack of government support.
South America	Technically Recoverable Reserves: 1,225 Tcf Several gas shale basins are located in South America, with Argentina having the largest resource base, followed by Brazil. Chile, Paraguay and Bolivia have sizeable shale gas reserves and natural gas production infrastructure, making these countries potential areas of development. Despite promising reserves, shale gas exploration and development in the region is almost negligible due to lack of government support, nationalization threats and absence of incentives for large scale exploration.
Europe	Technically Recoverable Reserves: 639 Tcf Europe has many shale gas basins with development potential in countries including France, Poland, the UK, Denmark, Norway, the Netherlands and Sweden. However, concerns over the environmental impact of fracturing and oil producers lobbying against shale gas extraction are holding back development in the region with some countries such as France going as far as banning drilling till further research on the matter. Some European governments, including Germany, are planning to bring stringent regulations to discourage shale gas development. Despite this, countries such as Poland show promising levels of shale gas leasing and exploration activity. Several companies are exploring shale gas prospects in the Netherlands and the UK.
Asia	Technically Recoverable Reserves: 1,389 Tcf China is expected to have the largest potential of shale gas (1,275 Tcf). State run energy companies like Sinopec are currently evaluating the country’s shale gas reserves and developing technological expertise through international tie-ups. However, no commercial development of shale gas has yet happened. Though both India and Pakistan have potential reserves, lack of government support, unclear natural gas policy and political uncertainty in the region are holding back the extraction development. Both Central Asia and Middle East are also expected to have significant recoverable shale gas reserves.
Africa	Technically Recoverable Reserves: 1,042 Tcf South Africa is the only country in African continent actively pursuing shale gas exploration and production. Other countries have not actively explored or shown interest in their shale gas reserves due to the presence of large untapped conventional resources of energy (crude oil, coal). Most potential shale gas fields are located in North and West African countries including Libya, Algeria and Tunisia.
Australia	Technically Recoverable Reserves: 396 Tcf Despite Australia’s experience with unconventional gas resource development (coal bed methane), shale gas development has not kicked off in a big way in Australia. However, recent finds of shale gas and oil coupled with large recoverable reserves has buoyed investor interest in the Australian shale gas.

What Are The Potential Negative Impacts Of Shale Gas Production?

Despite the large scale exploration and production of shale gas in the USA, countries around the world, especially in Europe, remain sceptical about it. Concerns over the environmental impact of hydraulic fracturing, lack of regulations and concerns raised by environmental groups have slowed shale gas development. Though there is no direct government or agency report on pitfalls of hydraulic fracturing, independent research and studies drawn from the US shale gas experience have brought forward the following concerns:

Will Shale Gas Solve Our Future Energy Needs?

Rarely does an energy resource polarize world opinion like this. Shale gas has divided the world into supporters and detractors. However, despite its potential negative environmental impact, shale gas extraction is associated with a range of unquestionably positive aspects, which will continue to support shale gas development:

Shale gas production will continue to increase in the USA and is expected to increase to 46% of the country’s total natural gas supply by 2035. USA is expected to transform from a net importer to a net exporter of natural gas by 2020.
Despite initial opposition, countries in Europe are opening up to shale gas exploration. With the EU being keen to reduce its dependence on imported Russian piped gas and nuclear energy, shale gas remains one of its only bankable long-term options. Replicating the US model, countries like Poland, the Netherlands and the UK are expected to commence shale production over the next two-five years and other countries are likely to follow suit.
Australian government’s keenness to reduce energy imports in addition to the recent shale gas finds has spurred shale gas development the country. Many companies are lining up to lease land and start shale gas exploration.
More stringent regulations from environment agencies are expected to limit the potential negative environmental impact of shale gas exploration.
Smaller energy companies that pioneered the shale gas revolution in the USA are witnessing billions of dollars worth of investments from multinational oil giants such as Exxon Mobil, Shell, BHP Billiton etc. are keen on developing an expertise in the shale gas extraction technology. These companies plan to leverage this technology across the world to explore and produce shale gas.The table below highlights major acquisitions and joint venture agreements between large multinational energy giants and US-based shale gas specialists over the last three years.

Major Deals in Shale Gas Exploration

Company	Acquisition/Partnership	Year	Investment
Sinopec	Devon Energy	January 2012	USD 2.2 billion
Total	Chesapeake Energy	January 2012	USD 2.3 billion
Statoil	Brigham Exploration	October 2011	USD 4.4 billion
BHP Billiton	Petrohawk	July 2011	USD 12.1 billion
BHP Billiton	Chesapeake Energy	February 2011	USD 4.75 billion
Shell	East Resources	May 2010	USD 4.7 billion
Exxon Mobil	XTO Energy	December 2009	USD 41.0 billion

Shale gas production is expected to spike in the coming three-five years. Extensive recoverable reserves, new discoveries, large scale exploration and development and technological improvement in the extraction process could lead to an abundant supply of cheap and relatively clean natural gas and reduce dependence on other conventional sources such as crude oil and coal For several countries including China, Poland, Libya, Mexico, Brazil, Algeria and Argentina, where the reserves are particularly large, shale gas might bring energy stability.

The need for energy security and desire to reduce dependence on energy imports from the Middle East and Russia (and hence to increase political independence), are likely to outweigh potential environmental shortfalls of shale gas production, and some compromise with environment protection activist groups will have to be worked out. Though the road to achieving an ‘energy el dorado’ appears to be long and rocky, it seems that with the right governments’ support, shale gas could become fuel that could significantly contribute to solving the world energy crisis over long term.

India – Reducing Reliance on Diesel

338views

India’s subsidy on diesel currently stands at about INR 950 billion (~ USD 19 billion).

Total diesel consumption was 64.74 million tons in 2011.

Diesel accounts for about 38% of India’s total fuel consumption.

3 million ton of diesel is consumed in private power generation.

On 17th January 2013, the Indian government took a major step towards the deregulation of diesel prices. A monthly (duration, undecided) hike of INR 0.50 (USD 0.01) for retail customers and INR 11.00 (USD 0.20) increase in diesel price for bulk customers has been proposed. This move is expected to reduce India’s fuel subsidy burden by about INR 150 billion (~ USD 3 billion) annually.

Why such high dependence on diesel?

Agriculture and power generation account for 20% of India’s diesel demand.

The agriculture sector, the mainstay of India’s economy, accounts for about 12% of India’s total diesel demand. For a typical Indian farmer engaged in semi-mechanized farming operations, diesel can account for up to 20% of the input cost. This primarily consists of expenses towards fuel used to plough field and a substantial amount used to operate water pumps for irrigation purpose.

The power sector demand for diesel is largely driven by inadequate and inefficient power generation, transmission and distribution infrastructure. As per available statistics, there is about 10% supply-demand gap in India’s power sector, which results in regular outages. Though India added about 20GW of generation capacity in 2011, more would be required if the country aims to match global per capita electricity consumption standards of 2,700Kwh. At present, India’s per capita consumption is about 900Kwh.

This mismatch in supply-demand of power is met by private power generation, accounting for 8% of India’s diesel demand. Shopping malls, housing societies, large hospitals and telecom towers are among the major consumers of diesel-generated power.

Across the country, diesel generators operate for 8-10 hours every day, to supplement government-supplied electricity, thus leading to excess demand for diesel.
According to government statistics available for 2011, private power generators and mobile phone towers consumed 4.6% and 1.93% of diesel, respectively.

Power is also lost in the form of aggregate technical and commercial losses, which amount to about 30% of the total power produced in the country. With a generation capacity of 205GW, approximately 60,000MW is lost while transmitting and distributing power to end-users.

As an indicator, reduction of these losses by even 50% can ensure power to about 8 million diesel pumps of 5 HP rating thereby saving of about 4-8 million litres of diesel per hour.
If the government took necessary steps to improve power availability by 50% of the current outage time (assumed to be eight hours daily as an average) then it is estimated that it would lead to the reduction of diesel usage in private power generation by about 4.5 million litres annually.

So, how can the heavy reliance on diesel be reduced?

Reduce price differential – Minimizing the price differential between petrol (gasoline) and diesel, which can be up to 30%, could go a long way in helping reduce the burden on diesel. Artificially-kept low diesel prices (coupled with better efficiency of diesel engines vis-à-vis petrol engine) have led to increased demand for diesel vehicles in India, thus resulting in greater diesel consumption. In 2012, diesel cars accounted for more than 50% of all passenger vehicles sold in India. In 2011, approximately 16% of diesel sold in India was consumed by passenger vehicles. Economists have often questioned the rationale behind selling subsidized diesel to passenger vehicle owners who can afford it at the market price. Policymakers have also mulled options to discourage the sale of diesel cars, which include higher taxes on diesel cars. However, such moves have been opposed by the Indian automobile industry. Industry experts admit that parity in diesel and petrol prices can shift balance in favour of petrol vehicles with a sales ratio of 55:45. For instance, if achieved in 2013, this could reduce the consumption of diesel by 200 million litres (based on a conservative estimate).
Alternate sources of power – Adoption of renewable sources of energy for power generation could also help in reducing the current diesel burden of India. Renewable power currently accounts for only about 12% of total installed capacity. For instance, an Indian telecom service provider Airtel has installed a 100 KW solar power plant in one of its major routing centres in Northern India. This is expected to save 26,000 litres of diesel annually. The company is planning to install similar system in six other locations as well.
Other measures – Better roads and highways would result in improved fuel efficiency of vehicles leading to lesser use of vehicles. Efficient intermodal logistics infrastructure, with a larger share of railways would reduce dependence on road transport.

Diesel demand in India would remain high due to its close linkage with day-to-day economic activity. However, it is apparent that current diesel usages are more than the actual requirement due to infrastructural shortcomings in the power sector. Therefore, addressing these issues would directly help in reducing diesel demand in India.

In the near term, it would be interesting to see how the gradual hike in diesel prices impact the economy at large, and more so, the budgets of the common man. As with several such measures in the past, the step towards change has to be politically driven and with general elections in sight in 2014, only time will tell how effective this much awaited reform is for India.

Solar Photovoltaic Market – Contemporary Scenario and Emerging Trends

As concerns about global climate change become more salient with growing population, depleting natural energy sources and subsequent rise in traditional energy prices, the search for alternative sources of power generation has become a prominent societal issue.

New sources of energy are typically not as cost competitive as traditional sources such as coal and natural gas, thus, local governments across various countries have rolled out incentives for private players to invest in the renewable energy sector, thus driving innovation and creation of cost-effective solutions.
