In the Islands, Renewable Energy Scales up Rapidly

— July 22, 2014

Renewable energy project developers are touring islands these days, salivating at the opportunity to displace diesel-powered electricity systems that can cost as much as $1/kWh with significantly lower-cost clean power.  Prominent examples include Iceland, where, according to the country’s National Energy Authority, roughly 84% of primary energy use comes from indigenous renewable energy sources (the majority from geothermal); Hawaii, where energy costs are 10% of the state’s GDP, and where the state government has set a goal of reaching 70% clean energy by 2030; and Scotland (part of a larger island), with a goal of 100% renewable energy by 2020.  Several smaller, equally interesting island electrification initiatives present great opportunities for companies looking for renewable energy deployment opportunities that are truly cost-effective for customers and developers.

These opportunities include:

  • In Equatorial Guinea, a 5 MW solar microgrid planned for Annobon, an island with 5,000 inhabitants off the west coast of Africa, is intended to supply 100% of the power for residential needs.  The project is funded by the national government with power produced at a rate 30% cheaper than diesel, the current primary fuel source.  The project is scheduled for completion in 2015 and is being installed through a partnership between Princeton Power Systems, GE Power & Water, and MAECI Solar.
  • The Danish island of Samsø is the first net zero carbon island, where 34 MW of wind power generate more electricity than is consumed on the island.  Fossil fuels are still utilized, so  Samsø is not truly a 100% renewable energy island as often reported.  The project was conceived and designed as part of a 10-year process begun in 1997, following the Kyoto climate meeting in Japan.
  • The island of Tokelau, an atoll in the South Pacific, is home to 1,500 inhabitants and produces up to 150% of its electrical needs with solar PV, coconut biofuel-powered generators, and battery storage – displacing 2,000 barrels of diesel per year and $1 million in fuel costs.
  • El Hierro, the westernmost of Spain’s Canary Islands, is home to 10,000 residents.  With an innovative combination of wind power and pumped hydro acting in tandem, the island is projected to generate up to 3 times its basic energy needs.  Excess power will be used to desalinate water at the island’s three desalination plants, delivering 3 million gallons of fresh water per day.
  • The Clinton Global Initiative has a specific Diesel Replacement Program for islands, focused on deploying renewable energy projects and strategies tailored to the unique needs of its 20 island government partners.  The objective is not only to create cost-effective solutions to reduce carbon, but also to help many of these island nations reduce the often enormous debt that results from relying on imported diesel fuel for electricity.

There are many more opportunities, including Crete, Madeira, Bonaire, La Reunion, the U.S Virgin Islands, and the Philippines (7,127 islands) – which last summer set a 100% renewable energy target within 10 years.

Not all of these projects, particularly the more sophisticated ones, have gone smoothly.  The logistical challenges of island construction add to the overall cost of the projects.  The risk of extreme tropical weather events is always present, including the risk of actually being underwater if sea levels rise as anticipated.  Thus far, financing for many of these projects has come from public-private partnerships, and as I’ve written previously, the coming avalanche of adaptation funding means those avenues are expected to be around for the foreseeable future.  But given the strong economic arguments for residential systems, resorts, agriculture, and other energy-intensive applications that often rely on diesel power for electricity, onsite distributed projects often pencil out without public assistance.

 

Solar PV Becoming Miners’ Friend

— May 12, 2014

At the Zwartkop Chrome Mine, near Thabazimbi, South Africa, mining company Cronimet Chrome SA has established a technological innovation – not below the ground, but above it.  To help power the mine, Cronimet installed a hybrid solar-diesel system that includes 4,158 solar photovoltaic (PV) panels, producing 1.8 GWh of electricity – about 60% of the mine’s power.  According to a report released by Carbon War Room in March, the Cronimet system will not only reduce fuel costs and carbon emissions for the mine, but also has the potential to “power local communities and improve the local economy.”

Like natural gas and wind power, solar PV and mining are becoming odd bedfellows – seemingly incongruent players in the energy landscape that are increasingly being paired to create win-win situations for each party.  Solar PV is increasingly being utilized to reduce the costs and lower the environmental damage of extracting coal and other minerals.  Chile, South Africa, and Australia are three of the leading countries where solar PV is being installed on mining operations, due to the remote location of the mining sites, unreliable (or nonexistent) electricity from the grid in the mining area, and the heavy use of diesel gensets in every aspect of mining operations.  Navigant Research’s Renewable Energy in the Mining Industry report forecasts that renewable technologies will supply between 5% and 8% of the world’s mining industry power consumption by 2022.

Winning Combination

The world’s largest solar PV company, U.S.-based First Solar, is now aggressively targeting diesel replacement solutions for African mines.  The company acquired Solar Chile, a Chilean project development company with a pipeline of 1.5 GW of solar PV, in 2013.  Much of this pipeline is in the Atacama Desert region, which boasts some of the highest solar irradiance in the world.  Combining high solar irradiance and high cost of electricity is a recipe for solar company success.  First Solar says its levelized cost of electricity is as low as 7 cents per kWh in such places – making it competitive with grid prices without subsidies.

In Australia, First Solar says it expects to develop as much as 200 MW of capacity for the mining industry over the next 3 years.  First Solar’s Sydney-based vice president of business development for Asia Pacific, Jack Curtis, tells Bloomberg News that mines are not as profitable as they used to be, meaning cost control is a bigger concern, and solar PV can be a hedge against volatile fuel costs.

Similar to wind, the solar PV market of today has evolved into a sophisticated global industry and has distanced itself in some ways from the us versus them approach of renewables and fossil fuels.   There can be synergies, albeit uncomfortable ones.

 

Hungry Solar Developers Look to Booming South Africa

— May 8, 2014

South Africa leads the renewable energy market in Africa.  The country has established a target of nearly 3.7 GW of renewables installed by 2030; in November 2013, it completed its third round of bids under the Renewable Energy Independent Power Producer Program, bringing the country to 86 MW of solar operating and nearly 1.5 GW in development.  The program provides power purchase agreements (PPAs) over 20 years with the country’s primary utility, Eskom, for projects up to 75 MW.  In the third round of bidding alone, the country procured 787 MW for wind projects, 450 MW for solar PV, and 200 MW of concentrating solar power (CSP).  There were also bids for 16.5 MW of biomass and 18 MW of landfill gas power.  Not bad for one of the top coal producing countries in the world.

As is common practice with bidding processes for any large infrastructure projects, the government included a local content requirement (LCR).  In the third round of bidding, the LCR was increased to 45% and, in a unique twist, the local company had to have a black South African shareholder majority.  Together, these requirements were expected to reduce the attractiveness to foreign companies and increase bid prices – both of which proved untrue.  The average price for solar PV projects dropped from around $3.50/W in the first round to less than $2.50/W in the second and third rounds.  This is competitive with solar being installed anywhere in the world today.

Open and Fair, Mostly

This is largely because the companies bidding include leading international project developers, such as Spain’s Abengoa, Italy’s Enel, China’s Longyuan Power, Norway’s Scatec, and SunPower Corporation (where France’s Total is now the majority shareholder).  China’s Trina Solar and U.S.-based First Solar are also active in South Africa.  While the market has either slowed down or become saturated in their home countries, international players are looking to emerging markets to grow sales.  This is a strong indicator of the hunger level of international power producers and the mature state of the solar PV industry in South Africa.

In general, bidders reported that they were generally pleased with the transparency of the process, typically a gripe when operating in emerging markets, including much of Africa.  There were construction delays for the first two rounds of projects and delays in announcing the third round of preferred bidders due to the overwhelming number of applicants – but these are to be expected as the country gets its first gigawatt under its belt.

The question is whether this apparent success can be replicated in other African countries.  Large-scale solar PV projects are operational in Reunion (15.6 MW), Mauritania (15 MW), and Cape Verde (5 MW), with a number of projects on the continent in development – notably Rwanda, with 8.5 MW.  Kenya, Tanzania, Nigeria, and Ghana are other countries with strong prospects and abundant activity in both on-grid and off-grid solutions.

 

Solar Market for Base of Pyramid Not So Pico

— April 14, 2014

In an upcoming report on pico solar lighting products (<10W) and solar home systems (<200W) sold primarily to rural communities in Africa and Asia, I cover the unit sales, revenue, and capacity of these small solar photovoltaic systems globally.  One of the most important trends covered in the report is that pico solar has transitioned from a humanitarian aspiration to big business – more than $100 million in 2014.  Corporate involvement in rural electrification has traditionally come in the form of corporate social responsibility initiatives, but real money is now flowing to solar companies serving the base of the pyramid market.  The success of a number of off-grid solar lighting companies and social enterprises has attracted interest from major corporations such as Panasonic, Schneider Electric, and Philips, as well as funding from investors.  Some of the more notable investments include:

  • In early 2014, d.light raised $11 million in Series C funding from DFJ, Omidyar Network, Nexus India Capital, Gray Ghost Ventures, Acumen Fund, and Garage Technology Ventures.  The company is one of the leading pico solar manufacturers, and has now raised $40 million and sold an estimated 6 million pico solar systems reaching 30 million people.
  • In early 2014, Persistent Energy Partners acquired Impact Energies, a pay-as-you-go, off-grid solar service provider working in West Africa that has reached 30,000 customers since 2011.  The renamed company, Persistent Energy Ghana, installs village solar microgrids and solar home systems.
  • In late 2013, Khosla Impact invested $1.8 million in a Series A round with BBOXX, a U.K.-based company that sells portable solar kits ranging from 7W to 185W and plug-and-play solar systems that range between 2 kW and 4 kW.  The company also provides a mobile pay-as-you-go service enabled by remote battery monitoring, which was the primary interest of Khosla.
  • In 2012, Greenlight Planet, one of the leading designers and distributors of solar light-emitting diode home lights, raised $4 million from Bamboo Finance and Dr. P.K. Sinha, co-founder of ZS Associates.  The investment followed previous financing by Dr. Sinha.  Greenlight Planet has sold more than 1.8 million solar lamps since the company was founded in 2008.
  • In 2012, Barefoot Power, one of the largest pico solar manufacturers, raised $5.3 million from three social investment funds (d.o.b. Foundation, ennovent, and Insitor Fund), existing shareholders (The Grace Foundation and Oikocredit Ecumenical Development Cooperative), and a number of private angel investors.

The full report will be released in the next few weeks.  It will discuss industry market drivers and challenges, and includes more than 20 company profiles and country-specific forecasts from 2014 to 2024.
