Solar power boom poses a distribution challenge

Photo by VnExpress/Quynh Tran.The increasing solar power capacity has made it difficult for national utility Vietnam Electricity (EVN) to ensure stable power distribution nationwide.

The nature of solar power capacity, which accounts for 25 percent of the total, is to produce high volumes during the day and no production in the evening. This poses difficulties for EVN in operating the national grid, the national utility has said in a report.

There have been times when the grid was oversupplied during the low-demand hours between 10 a.m. and 2 p.m. when solar radiation is at peak, the report says.

On the contrary, when power demand is at the highest, the 5:30-6:30 p.m. period, solar power production falls to nearly zero and the traditional power generators have to be mobilized.

“The ratio of renewable power generation is increasing and with it comes instability in operation,” the report says.

Vietnam’s solar power capacity was roughly 16,500 megawatt by the end of last year, nearly 48 percent of it coming from rooftop panels and the rest from plants.

Solar power production reached 10.6 billion kilowatt-hours last year, accounting for 4.3 percent of total.

There was a surge in the number of solar power projects after the government offered an incentive feed-in tariff scheme to promote renewable energy production to meet rising demand in a fast-growing economy.

Vietnam’s national grid is ill-equipped to handle the power surge from new renewable energy plants seeking to come online this year.

National utility Vietnam Electricity (EVN) has said in a recent report that the construction of new transmission lines might not be able to match the speed of new solar and wind power projects.

Seasonal pumped hydropower storage (SPHS), an already established yet infrequently used technology, could be an affordable and sustainable solution to store energy and water on an annual scale, according to new IIASA research published in the journal Nature Communications. Compared with other mature storage solutions, such as natural gas, the study shows that there is considerable potential for SPHS to provide highly competitive energy storage costs.

Solar Farms Without Subsidy Sprout From Gloomy Britain to Italy
Green Energy Is Finally Standing on Its Own Feet

Next to a wheat field north of London, banks of solar panels in 35 neat rows are generating electricity without any support from the government.

Despite Britain’s reputation for grey skies, the closely-held developer Anesco Ltd. is building the hybrid solar and battery facility in Milton Keynes with its own capital. It’s just one of about 15 photovoltaic projects underway from Italy to the U.K. that aren’t relying on subsidies to make a profit, according to Bloomberg NEF, which anticipates many more to come.

RENEWABLES 2018 GLOBAL STATUS REPORT: A comprehensive annual overview

This document presents the overarching trends and development from 2018 so that policy makers and others can more easily understand the significance of the latest renewable energy development. It outlines what is happening to drive the energy transition and details why it is not happening fast enough or as fast as possible. It draws on the meticulously documented data found in REN21’s Renewables 2018 Global Status Report. See the endnotes and methodological notes in the full report for further details at

Renewable Energy Auctions: A Guide to Design


Auctions for contracts to develop power-generation capacity have emerged as an essential policy instrument for many countries to promote the transition to renewable energy sources and technologies. This six-volume guide from the International Renewable Energy Agency (IRENA) notes more than 60 countries using renewable energy auctions by 2015, mainly in order to attract competition and drive down costs.

Renewable Energy Auctions: A Guide to Design aims to advise policy makers on the implications of different approaches to such auctions. The set – structured around key auction design elements – offers choices and recommendations to support optimal decision-making in different contexts. Auction designs can emphasise cost effectiveness, supply security or socio-economic development objectives. Tiếp tục đọc “Renewable Energy Auctions: A Guide to Design”

What If All U.S. Coal Workers Were Retrained to Work in Solar?

AUGUST 08, 2016 _The global economy is in a massive transition from a fossil-fuel-based energy system to one using sophisticated renewable energy technologies. For tens of thousands of fossil fuel workers, though, the energy industry outlook is not promising. For coal industry workers, the future looks particularly bleak. However, research I conducted with Edward Louie of Oregon State University offers hope for a better future based on retraining workers. Our study (published in the journal Energy Economics) quantified the costs and benefits of retraining coal workers for employment in the rapidly expanding solar photovoltaic industry—and it explores different ways to pay for this retraining.

Vietnam’s Homegrown System for Saving Water

A young man returned home to invent an internet-integrated system that helps farmers produce more food with less water.

Tri Nguyen, CEO of MimosaTEK, was born and raised in Dalat, a city in the Central Highlands region of Vietnam, where the land is mountainous and fertile. He grew up surrounded by local farmers who planted a rich variety of products ­— from bell peppers and flowers to coffee and bananas. Tri moved to Ho Chi Minh City to work in the information technology sector as a young man, but when the opportunity came, he decided to return to his roots and start a strawberry farm with his friends in Dalat.

Tri turned to the local farmers to learn everything he could about growing strawberries. But he kept hearing something that didn’t seem right: The farmers instructed him to irrigate until water dripped out of the soil when he picked it up in his hands.

Tri did some research that confirmed his instincts: The farmers didn’t need to be using that much water. But when he told his neighbors, they insisted on continuing to overwater their crops. It was how they were taught and how they had farmed all their lives.

“I realized then that the farmers based their decisions on experiences instead of scientific data,” says Tri.

Smallholder and family farmers in Dalat water their crops based on what they see and feel. They don’t consult data on the weather or rainfall because they were never taught to do so. This is leading to excessive irrigation, which can stunt growth or kill crops, and deplete limited groundwater. Furthermore, Vietnam is still recovering from its strongest-ever drought, and every drop counts. Many of Dalat’s farmers are already suffering from water shortages.
