‘Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now – overwhelmingly – a smart economic one’

Renewable energy will be cheaper than fossil fuels in two years, according to a new report.

Experts predict that investment in green infrastructure projects will lead to decreases in the cost of energy for consumers.

Continuous technological improvements have led to a rapid fall in the cost of renewable energy in recent years, meaning some forms can already comfortably compete with fossil fuels.

The report suggests this trend will continue, and that by 2020 “all the renewable power generation technologies that are now in commercial use are expected to fall within the fossil fuel-fired cost range”.

Of those technologies, most will either be at the lower end of the cost range or actually undercutting fossil fuels.

“This new dynamic signals a significant shift in the energy paradigm,” said Adnan Amin, director-general of the International Renewable Energy Agency (IREA), which published the report.

“Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now – overwhelmingly – a smart economic one.”

The report looked specifically at the relative cost of new energy projects being commissioned.

As renewable energy becomes cheaper, consumers will benefit from investment in green infrastructure.

“If the stuff you’re building to generate electricity costs less, the end effect of that is having to pay less for the electricity that comes from it,” Jonathan Marshall, energy analyst at the Energy and Climate Intelligence Unit (ECIU) told The Independent.

“The cheaper you install it, the better it is for everyone.”

The current cost for fossil fuel power generation ranges from around 4p to 12p per kilowatt hour across G20 countries.

By 2020, IREA predicted renewables will cost between 2p and 7p, with the best onshore windand solar photovoltaic projects expected to deliver electricity by 2p or less next year.

Other methods of producing renewable energy, such as offshore wind farms and solar thermal energy, are not yet as competitive as fossil fuels.

However, the results of recent renewable power auctions for projects to be commissioned in the coming years suggest these forms too are due to drop in price.

Auctions provide a useful means of predicting the future cost of electricity.

“These cost declines across technologies are unprecedented and representative of the degree to which renewable energy is disrupting the global energy system,” said Mr Amin.

solar power philippines

Philippine facilities occupy 10 slots in Southeast Asia’s top 25 operational solar power plants, and electricity produced from this technology is expected to triple in four years, according to Dutch firm Solarplaza.

The Rotterdam-based consultancy said in a report that grid-connected solar power capacity in the Philippines was expected to more than triple from 903 megawatts currently to 3 gigawatts by 2022.

Rivaling the Philippines is Thailand with 15 solar facilities in the list. The remaining two are located in Malaysia and Cambodia.

No. 1 in Solarplaza’s list is 132.5-MW Cadiz solar power plant in Negros Occidental. Owned by the Equis Fund Group, this went online in 2016 and is the biggest in Southeast Asia.

Other Philippine solar plants listed by Solarplaza are the 80-MW San Carlos Solar Energy plant (ranked 8th); 63-MW Solar Philippines plant in Calatagan, Batangas (9th) ; 59-MW Toledo project of Citicore Power in Cebu (10th), and 59-MW San Carlos Sun Power plant in Negros Occidental (11th).

There are also the 50-MW plant of Sulu Electric Power and Light in Leyte (12th); 50-MW plant of Syntegra Solar and Conergy in Tarlac (13th); 45-MW plant of San Carlos Solar Energy in San Carlos City (14th); 40-MW plant of Majestics energy Corp. and Mother Co. in Cavite (16th); and 22-MW plant of Mabalacat Solar Philippines in Pampanga.

“The Philippines has enjoyed large growth in PV (photovoltaic) installations in the past few years, with more than 881 MW of newly added capacity installed since 2014,” Solarplaza said.

“This was mainly the result of the introduction of the country’s initial feed-in-tariff (FiT) of $0.23 per kilowatt-hour in 2014 and its subsequent revision to $0.17 per kWh in 2017,” the group added.

In an earlier report, Solarplaza put the Philippines at No. 5 among developing countries in Asia in terms of the use of solar photovoltaic systems for electricity generation.

Solar Power Is Burning Bright

UNITED NATIONS — Solar panels are everywhere: perched on thatched roofs in rural Kenya, helping Indian farmers pump groundwater for their fields, and powering United States military bases.

Solar power accounted for more than a third of all electricity generated from energy sources that came online in 2017, a larger share than any other new source, the United Nations Environment Program said in a report issued Thursday.And solar power is becoming much more affordable. The cost of electricity from large-scale solar projects has dropped by 72 percent since 2009, according to the study.

But even as solar, along with its renewable energy cousins — like wind, biomass and geothermal power — expands, it still accounts for barely 12 percent of all the electricity that the world consumes. The greatest share still comes from fossil fuels like coal, and more coal-fired power plants continue to be built, contributing to the greenhouse gas emissions that have warmed the planet to dangerous levels.

“This shows where we are heading,” said Nils Stieglitz, a professor at the Frankfurt School of Finance & Management, which produced the report along with Bloomberg New Energy Finance.

“The fact that renewables altogether are still far from providing the majority of electricity means that we still have a long way to go.”

The world leader in investing in renewables, by far, is China. The country accounted for nearly half of all renewable energy investments worldwide, pumping $86.5 billion into solar energy alone in 2017 in what the report described as “an extraordinary solar boom.”

China has cut back significantly on coal at home, though it has continued to fund and build coal-fired power plants abroad. One of the most closely watched is a proposed plant on the coast of Kenya, near the ancient island town of Lamu, a Unesco world heritage site.

The United States also plays a leading role in developing solar power. It is historically the largest emitter of greenhouse gases, though, and its investments in renewables went down slightly in 2017, according to the report, to $40.5 billion.

That decline coincides with President Trump’s first year in office, a steady rollback in environmental protections and the announced pullout of the United States from the Paris climate agreement. Few countries are even close to meeting the targets they set under the Paris agreement, according to independent analyses.

European investment in renewables fell in 2017, according to the report, in large part, its authors said, because of Britain, which has moved to end subsidies for wind and solar projects. 

That pointed to a looming challenge for the renewables industry: whether it can grow without government subsidies.

“Many projects will have to sink or swim without any government-backed price support,” the report said.

Renewables grew most significantly in 2017 where the demand for electricity also grew. The report found that developing economies accounted for 63 percent of global investment in renewable energy in 2017, up from 54 percent the year before. All told, 157 gigawatts of renewable power came online in 2017, more than double the 70 gigawatts generated from new fossil fuel sources.

The United Nations secretary general, António Guterres, has called climate change the biggest threat to humanity.

philippines top in asia solar power

The Philippines ranked No. 1 among developing countries in Asia in terms of the use of solar photovoltaic systems for electricity generation, according to a Dutch consultancy firm.

Rotterdam-based Solarplaza also ranked the Philippines fifth worldwide, following Chile, South Africa, Brazil and Thailand.

“The country (Philippines) is still relatively young when it comes to solar development, but was able to get seven active projects ranked in the top 50 list,” Solarplaza research analyst Marco Dorothal said in a report.

Dorothal was referring to Solarplaza’s top 50 solar PV projects in emerging markets.

He noted that the biggest operational project in the Philippines was currently the 132.5-megawatt Cadiz solar power plant developed by Helios Solar Energy Corp., a joint venture between Thailand-based Soleq Solar Co. and Gregorio Araneta Inc.

“The commissioning of this plant solidifies the solar market in the Philippines as being capable of handling such large-scale utility projects,” Dorothal said.

Solarplaza also noted that homegrown firm Solar Philippines last March started building a 150-MW solar plant in Tarlac, making it the largest solar power project so far for the country.

Solar Philippines has also opened the country’s first PV module factory in Batangas.

As of June 2017, Solarplaza pegs the Philippines’ solar power installed capacity at 900 MW.

“The developments in the market are promising, but it still needs to be seen how much this will benefit the country as Solar Philippines aims to produce PV modules for the US and European markets,” Dorothal said.

Further, Solarplaza said that while the Philippines was going through some policy changes, the solar market had been getting much support from the government.

“Two new operating projects [that made it to Solarplaza’s Top 50 list] have led the Philippines to increase its capacity with 110 MW compared to what was previously reported,” Dorothal said.

“The country also has a major project still in the pipeline that could once again increase the [installed] MW capacity of the Philippines in the Top 50 list,” he added.

According to the International Energy Agency, solar power is turning into the cheapest source of new electricity generation capacity in many countries, especially in Asia.

“Solar is forging ahead in global power markets as it becomes the cheapest source of electricity generation in many places, including China and India,” IEA executive director Fatih Birol said in a statement.

The IEA expects that, over the next 25 years, the world’s growing energy needs are met first by renewables and natural gas as fast-declining costs turn solar power into the cheapest source of new electricity generation.

Solar PV systems are set to lead new generating capacity, mainly driven by the technology’s adoption in China and India.

5 ways to engage employees in energy savings

Here’s a low-cost way businesses can lower their energy bills: Get employees to chip in.

Simple steps such as turning off lights when rooms are unoccupied, or turning off and unplugging office equipment such as computers, printers and copiers at night can help a business save hundreds of dollars annually on their energy bills. Yet, many employees don’t do it.

The reasons vary. Some people simply aren’t programmed to think about energy conservation and thus forget to, say, turn off lights when they leave rooms. Others don’t see personal value in taking time to unplug equipment. It only takes a couple minutes to turn off and unplug a computer, yet that’s a minute or two they figure can be better spent doing something else (and besides, they’re not paying the energy bills). Some might even believe their employer wants them to leave the lights and equipment on.

So, then, how do you motivate them to make energy conservation part of their workday? Here are five strategies for getting employees engaged in energy savings:

1. Educate employees.

A big reason many people don’t take conscious effort to save energy is they don’t realize the full financial and environmental benefits. Employers can change this by providing employees with information. Managers might send emails with factoids on energy savings (such as, turning off a printer at night saves the equivalent of 1,500 photocopies.) Some businesses even host lunch seminars to help employees. (You can find some information on the cost of running office equipment here.)

2. Form a team.

Some of the most effective workplace campaigns come not from managers, but other employees. Some companies start “green teams” made up of employees who encourage their colleagues to be more environmentally conscious. Such team could also tackle energy conservation and find ways to educate and motivate their colleagues to save energy.

3. Constant reminders.

For many people, not turning things off is habit, and habits are hard to change. Putting signs in key places around the office, such as by the printer or by the doors, reminding people to turn off lights or turn off their computers can make a big difference. And of course, managers should be energy-saving role models: employees will only pitch in if the boss walks the walk.

4. Rewards.

Businesses have shown that offering employees some financial incentive for eco-conscious moves, such as buying a hybrid vehicle or taking public transportation to work, can pay off. Companies could motivate employees to save energy by, say, giving gift cards to employees who do the most to save energy or come up with a workplace strategy for doing so.

5. Make it fun.

There’s growing recognition that the most successful approaches to make people voluntarily participate in environmentally conscious activities is to make them fun, positive and interesting. At a workplace, this might mean hosting an employee competition or producing a funny video about ways employees can save energy.

Solar Power for Disaster Response and Recovery

Two seemingly separate trends are currently colliding. One is the more severe and widespread damage being inflicted on electric grids during natural disasters, especially from the increasingly stronger storms like hurricane Maria that devastated Puerto Rico. The second is the many technological advances in solar power generation and energy storage, which also lead to ongoing cost reductions across the solar value chain.

The prospect of using solar power on a temporary basis, including for disaster response and recovery, is not new, of course. Indeed, Hurricane Hugo in 1988 is believed to be the first time that solar power was used for relief in the aftermath of a natural disaster. Despite the fact that solar PV and related technologies have advanced considerably during the nearly three decades since then, diesel gensets continue to dominate disaster relief efforts. So is it finally time for the solar energy industry to get serious about this growing need?

The Case for Solar

Time, and not cost or capacity, is now the most critical factor for why solar power affords a viable, and often superior, alternative to gensets for disaster relief. When immediate failover from the electric grid is critical, as it is for hospitals, it is difficult to compete with standby generators powered by diesel fuel, liquid natural gas or propane. Even a hospital on a solar-powered microgrid would likely have a backup generator.

When response can occur on the order of hours or days, however, with systems being hauled or flown in, the playing field is now fairly level. For systems with a comparable size and weight (including battery storage for the solar system), the generator will likely have an advantage in terms of kilowatts produced. But generators need fuel, which must also be hauled or flown in, and not just once, but for as long as power is needed.

This need to continuously refuel generators is what gives solar its major advantage: The longer it might take to fully restore the electric grid, the better the case for solar. This is especially true for modular ground mount solar arrays, which scale more easily and cost-effectively than other configurations (covered next). And the longer the recovery period, the greater the advantage solar+storage solutions enjoy.

Scaling Solar Power

During periods of disaster response, localized needs for temporary power can range from 100 watts to 100 kW, and this can also be an advantage for solar. At the risk of over-simplification, portable solar systems are available in four configurations: suitcase, trailer, container and full array. Each has a role to play in different use cases in virtually every disaster response and recovery scenario.

The suitcase is ideal for restoring communications by providing power for both portable 3G/4G cells and user device charging stations. These systems, which can also be used to power some medical equipment, range in size from around 50 to 200 watts with between 10 and 100 amp-hours of battery storage.

The typical trailer might have a 5-kW solar array and 100-200 kWh of storage, and can be fully operational in less than 30 minutes. The higher capacities make these suitable for powering small medical clinics and shelters.

Shipping containers are commonly used to transport equipment and supplies during disaster relief efforts, and they are also ideal for packaging a complete solar+storage power station. A 20-foot container, for example, could support up to 50 kW of power and 500 KWh of storage to accommodate larger clinics, shelters and businesses, as well as small hotels, apartments, and water pumps or wells.

Those three systems are commercially available in different sizes to meet different needs, not only for disaster relief, but also for temporary/tactical deployments, such as those needed by the military. What has been lacking for solar power is a configuration that scales more cost-effectively, and the portable and modular ground mount solar array is now filling this need.

Making modular ground mount solar arrays portable and suitable for disaster response and recovery requires that the entire system—including its foundation—be installable quickly by small crews using only handheld tools. The earth anchor, which has long been used by electric utilities for guy-wiring powerline poles, provides the basic technology needed to make such simple installation possible.

For example, a complete, pre-assembled 5-kW system, which can be delivered folded on a trailer or truck, or in a shipping container, can be installed by a three-person crew in about an hour. The entire system is just as quickly and easily uninstalled (to be “lifted and shifted” to another site or stored in preparation for the next disaster), leaving behind only the relatively inexpensive earth anchors, and those can even be removed if required.

In addition to their virtually unlimited scalability, these “temporary” modular ground mount solar systems have one other advantage that also involves time: They can become permanent in distributed microgrids, even in hurricane-prone places like Puerto Rico. Rigorous testing in wind tunnels has certified a standard earth anchor as being able to secure uplift forces caused by 150 miles-per-hour winds—a category 4 hurricane. For greater protection, stronger and/or additional earth anchors can be used.

Puerto Rico Hospital With Solar Power Installation

After Tesla CEO Elon Musk promised earlier this month to help restore power in Puerto Rico, the company has brought electricity back to a hospital on the island, which was recently battered by Hurricane Maria. In a tweet Tuesday, Tesla posted photos of Hospital del Niño, where it just completed installation of solar panels and large battery packs to provide power even with the grid down. The batteries can store excess energy harvested by the solar panels, ensuring a steady flow of power even when sunlight isn’t available.

Tesla first discussed sending energy-storage battery packs to Puerto Rico as a source of emergency power in late September, and Musk pledged to go all-in October 5. Not surprisingly for the Twitter-loving CEO, the relief effort was shaped by a series of tweets.

When asked whether Tesla could help restore power to Puerto Rico, Musk replied in the affirmative, saying the company had already undertaken electricity projects on smaller islands and that the technology could be scaled up. The final decision would be up to the Puerto Rico government, Musk noted. Puerto Rico Governor Ricardo Rosselló subsequently replied “Let’s talk.”

Even without the added impetus of compensating for hurricane damage, islands are particularly well-suited to renewable energy and electrical storage. They’re not connected to the mainland grid, after all, and generating power locally can be difficult, as fuel must be shipped in. Prior to Hurricane Maria, most of Puerto Rico’s power was generated by burning oil, which had to be imported.

Tesla has said it will delay the unveiling of its much-discussed electric semi-truck in order to focus on the Puerto Rico effort. Musk previously said the truck would be unveiled in September, but that was pushed back one month before being delayed again due to the hurricane-relief effort. Tesla now says the semi truck will debut November 6.

Shell Foundation-Victron Energy Microgrid Philippines

In December last year we reported on the first ‘Access to Energy’  Shell Foundation – Victron Energy microgrid in Ligad, North of Palawan island in the Philippines. Thousands of people still live in such areas where there is no access to electricity and the likelihood of any utility grid connection is aeons away. The Shell Foundation however set about changing that with the advent of that initial Ligad microgrid using Victron components. Now there is a second – and as I write this blog a third is also on its way. Power for the powerless is certainly becoming a reality.

Palawan island

Let’s just remind ourselves of the area for these projects. Palwawan island has been chosen several times as the most beautiful island in the world. Not surprising really as the Province of Palawan is an archipelago in the Philippines which includes two UNESCO World Heritage Sites plus breathtaking endless white beaches, wild forests and rugged mountains – all of a pure and untouched nature. The Puerto Princesa Subterranean River National Park for instance is classed as one of the New7Wonders of Nature.

Microgrid No 2

Like the first microgrid this second one is situated in the North of Palawan island, but this time it is the village of Sitio Binaluan, Barangay (meaning rural district) Liminangcong, in the municipality of Taytay. Victron Energy equipped once again, this microgrid is for 95 houses and has been up and running since February this year.

Challenging logistics

Once again it was Koos and Josie Mulder of JK Solar Power House and their team who did the impossible.

It might not be the correct photo size ‘exactly’ for this blog of the team – but as you’ll see there were far greater challenges than pressing a camera button and sending me large format photos – so it would be remiss of me not to include the photo of these stalwarts!

So, back to challenging logistics?

Besides the Victron kit above – how about a 1,200 kg generator, 3,750 kg of batteries, 1,200 kg of solar panels, a 200 kg wind turbine, plus all the electricity posts, wires and ancillaries to transport and install. I’ll let the photos explain…

System stats

The solar system can supply an average of 60kWh/day, in summertime even a little bit
more. In the rainy season or during a typhoon there is the genset as a backup, in case solar and
wind production should not be enough.

System Components:

  • 2 x Quattro 10kVa units in parallel
  • 4 x BlueSolar 150V/85A MPPTs in parallel
  • 1 x BMV-700 Series battery monitor
  • 1 x Color Control GX
  • 60 x 260W solar panels giving 15.6kWp
  • 1 x 5kW Wind Turbine
    OPZV 48V/2,000Ah battery bank
  • 33 kVa Diesel genset with automatic start/stop
  • The microgrid can be monitored via the Victron VRM website, but is unfortunately not always online. Whilst a good electricity supply has been achieved – it seems a solid internet connection is still on the wish list!

What a delight to see power being brought to yet another community and who better to sum up than Danny Maesen of PhilSolar, who said:

“Again, a whole community has access to basic electricity and they can only benefit from it, for education, computers or laptops, for comfort such as some fans or a few freezers for ice making, streetlights, TV – the simple things which will change their lives forever.

Many thanks to the Shell Foundation for choosing Victron Energy equipment supply and my personal thanks to Koos, Josie and the team, for their efforts, commitment and enthusiasm for Victron Energy products.”
