Last month, Electricity of Vietnam EVN, in association with Japan International Cooperation Agency Vietnam JICA Vietnam and Xuan Thien Ninh Binh Company Limited, announced that it would be building the country's first pumped-storage hydroelectric power station in the Son La Province.

Mountainous Son La is about 200 kilometers from Hanoi and shares a southern border with Laos. The exact location of the plant is yet to be determined however, Deputy Prime Minister Hoang Trung Hai has given his seal of approval to the project.

As of now, EVN and its associates are developing the project scope, and construction is scheduled to commence during the second quarter of 2013. The Dong Phu Yen Pumped-Storage Power Station is planned to house five 300-megawatt MW pump turbine generators to produce 1,500 MW when completed and operational in 2018. EVN, JICA Vietnam, and Xuan Thien Ninh Binh are planning to begin searching for equipment providers and subcontractors after they have completed the scope of the project. The project is estimated to cost US$1 billion.

JICA is a well-known Japanese governmental organization that provides official developmental assistance on behalf of the government of Japan. The organization is merged with the Japan Bank for International Cooperation JBIC and is responsible for dispensing loans to developing countries. JICA and EVN have worked together on numerous projects to develop Vietnam's installed power supply.

Can COVID-19 accelerate funding for access to electricity?

Africa Energy Access Funding faces disbursement bottlenecks as SDG 7 goals demand investment in decentralized solar, minigrids, and rural electrification; COVID-19 pressures donors, requiring faster approvals, standardized documentation, and stronger project preparation and due diligence.

 

Key Points

Financing to expand Africa's electrification, advancing SDG 7 via disbursement to decentralized solar and minigrids.

✅ Accelerates investment for SDG 7 and rural electrification

✅ Prioritizes decentralized solar, minigrids, and utilities

✅ Speeds approvals, standard docs, and project preparation

 

The time frame from final funding approval to disbursement can be the most painful part of any financing process, and the access-to-electricity sector is not spared.

Amid the global spread of the coronavirus over the last few weeks, there have been several funding pledges to promote access to electricity in Africa. In March, the African Development Bank and other partners committed $160 million for the Facility for Energy Inclusion to boost electricity connectivity in Africa through small-scale solar systems and minigrids. Similarly, the Export-Import Bank of the United States allocated $91.5 million for rural electrification in Senegal.

Rockefeller chief wants to redefine 'energy poverty'

Rajiv Shah, president of The Rockefeller Foundation, believes that SDG 7 on energy access lacks ambition. He hopes to drive an effort to redefine it.

Currently, funding is not being adequately deployed to help achieve universal access to energy. The International Energy Agency’s “Africa Energy Outlook 2019” report estimated that an almost fourfold increase in current annual access-to-electricity investments — approximately $120 billion a year over the next 20 years — is required to provide universal access to electricity for the 530 million people in Africa that still lack it.

While decentralized renewable energy across communities, particularly solar, has been instrumental in serving the hardest-to-reach populations, tracking done by Sustainable Energy for All — in the 20 countries with about 80% of those living without access to sustainable energy — suggests that decentralized solar received only 1.2% of the total electricity funding.

The spread of COVID-19 is contributing significantly to Africa’s electricity challenges across the region, creating a surge in the demand for energy from the very important health facilities, an exponential increase in daytime demand as a result of most people staying and working indoors, and a rise from some food processing companies that have scaled up their business operations to help safeguard food security, among others. Thankfully — and rightly so — access-to-electricity providers are increasingly being recognized as “essential service” providers amid the lockdowns across cities.

To start tackling Africa’s electricity challenges more effectively, “funding-ready” energy providers must be able to access and fulfill the required conditions to draw down on the already pledged funding. What qualifies as “funding readiness” is open to argument, but having a clear, commercially viable business and revenue model that is suitable for the target market is imperative.

Developing the skills required to navigate the due-diligence process and put together relevant project documents is critical and sometimes challenging for companies without prior experience. Typically, the final form of all project-related agreements is a prerequisite for the final funding approval.

In addition, having the right internal structures in place — for example, controls to prevent revenue leakage, an experienced management team, a credible board of directors, and meeting relevant regulatory requirements such as obtaining permits and licenses — are also important indicators of funding readiness.

1. Support for project preparation. Programs — such as the Private Financing Advisory Network and GET.invest’s COVID-19 window — that provide business coaching to energy project developers are key to helping surmount these hurdles and to increasing the chances of these projects securing funding or investment. Donor funding and technical-assistance facilities should target such programs.

2. Project development funds. Equity for project development is crucial but difficult to attract. Special funds to meet this need are essential, such as the $760,000 for the development of small-scale renewable energy projects across sub-Saharan Africa recently approved by the African Development Bank-managed Sustainable Energy Fund for Africa.

3. Standardized investment documentation. Even when funding-ready energy project developers have secured investors, delays in fulfilling the typical preconditions to draw down funds have been a major concern. This is a good time for investors to strengthen their technical assistance by supporting the standardization of approval documents and funding agreements across the energy sector to fast-track the disbursement of funds.

4. Bundled investment approvals and more frequent approval sessions. While we implement mechanisms to hasten the drawdown of already pledged funding, there is no better time to accelerate decision-making for new access-to-electricity funding to ensure we are better prepared to weather the next storm. Donors and investors should review their processes to be more flexible and allow for more frequent meetings of investment committees and boards to approve transactions. Transaction reviews and approvals can also be conducted for bundled projects to reduce transaction costs.

5. Strengthened local capacity. African countries must also commit to strengthening the local manufacturing and technical capacity for access-to-electricity components through fiscal incentives such as extended tax holidays, value-added-tax exemptions, accelerated capital allowances, and increased investment allowances.

The ongoing pandemic and resulting impacts due to lack of electricity have further shown the need to increase the pace of implementation of access-to-electricity projects. We know that some of the required capital exists, and much more is needed to achieve Sustainable Development Goal 7 — about access to affordable and clean energy for all — by 2030.

It is time to accelerate our support for access-to-electricity companies and equip them to draw down on pledged funding, while calling on donors and investors to speed up their funding processes to ensure the electricity gets to those most in need.

Nova Scotia Power says it now generates 30 per cent of its power from renewables

Nova Scotia Power Renewable Energy delivers 30% in 2018, led by wind power, hydroelectric and biomass, with coal and natural gas declining, as Muskrat Falls imports from Labrador target 40% renewables to cut emissions.

 

Key Points

It is the utility's 30% 2018 renewable mix and plan to reach 40% via Muskrat Falls while reducing carbon emissions.

✅ 18% wind, 9% hydro and tidal, 3% biomass in 2018

✅ Coal reliance fell from 76% in 2007 to 52% in 2018

✅ 58% carbon emissions cut from 2005 levels projected by 2030

 

Nova Scotia's private utility says it has hit a new milestone in its delivery of electricity from renewable resources, a trend highlighted by Summerside wind generation in nearby P.E.I.

Nova Scotia Power says 30 per cent of the electricity it produced in 2018 came from renewable sources such as wind power.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke. Another 13 per cent come from burning natural gas and five per cent from imports, even as U.S. renewable generation hits record shares.

The utility says that since 2007, the province's reliance on coal-fired plants has dropped from 76 per cent of electricity generated to 52 per cent last year, as Prairie renewables growth accelerates nationally.

It says it expects to meet the province's legislated renewable target of 40 per cent in 2020, when it begins accessing hydroelectricity from the Muskrat Falls project in Labrador.

"We have made greener, cleaner energy a priority," utility president and CEO Karen Hutt said in a news release.

"As we continue to achieve new records in renewable electricity, we remain focused on ensuring electricity prices stay predictable and affordable for our customers, including solar customers across the province."

Nova Scotia Power also projects achieving a 58 per cent reduction in carbon emissions from 2005 levels by 2030.

A tidal project in Scottish waters just generated enough electricity to power nearly 4,000 homes

MeyGen Tidal Stream Project delivers record 13.8 GWh to Scotland's grid, showcasing renewable ocean energy. Simec Atlantis Energy's 6 MW array of tidal turbines advances EU power goals and plans an ocean-powered data center.

 

Key Points

A Scottish tidal energy array exporting record power, using four 1.5 MW turbines and driving renewable innovation.

✅ Delivered 13.8 GWh to the grid in 2019, a project record.

✅ Four 1.5 MW turbines in Phase 1A, 6 MW installed.

✅ Plans include an ocean-powered data center near site.

 

A tidal power project in waters off the north coast of Scotland, where Scotland’s wind farms also deliver significant output, sent more than 13.8 gigawatt hours (GWh) of electricity to the grid last year, according to an operational update issued Monday. This figure – a record – almost doubled the previous high of 7.4 GWh in 2018.

In total, the MeyGen tidal stream array has now exported more than 25.5 GWh of electricity to the grid since the start of 2017, according to owners Simec Atlantis Energy. Phase 1A of the project is made up of four 1.5 megawatt (MW) turbines.

The 13.8 GWh of electricity exported in 2019 equates to the average yearly electricity consumption of roughly 3,800 “typical” homes in the U.K., where wind power records have been set recently, according to the company, with revenue generation amounting to £3.9 million ($5.09 million).

Onshore maintenance is now set to be carried out on the AR1500 turbine used by the scheme, with Atlantis aiming to redeploy the technology in spring.

In addition to the production of electricity, Atlantis is also planning to develop an “ocean-powered data centre” near the MeyGen project.

The European Commission has described “ocean energy” as being both abundant and renewable, and milestones like the biggest offshore windfarm starting U.K. supply underscore wider momentum, too. It’s estimated that ocean energy could potentially contribute roughly 10% of the European Union’s power demand by the year 2050, according to the Commission.

While tidal power has been around for decades — EDF’s 240 MW La Rance Tidal Power Plant in France was built as far back as 1966, and the country’s first offshore wind turbine has begun producing electricity — recent years have seen a number of new projects take shape.

In December last year, Scottish tidal energy business Nova Innovation was issued with a permit to develop a project in Nova Scotia, Canada, aiming to harness the Bay of Fundy tides in the region further.

In an announcement at the time, the firm said a total of 15 tidal stream turbines would be installed by the year 2023. The project, according to the firm, will produce enough electricity to power 600 homes, as companies like Sustainable Marine begin delivering tidal energy to the Nova Scotia grid.

Elsewhere, a business called Orbital Marine Power is developing what it describes as the world’s most powerful tidal turbine, with grid-supplied output already demonstrated.

The company says the turbine will have a swept area of more than 600 square meters and be able to generate “over 2 MW from tidal stream resources.” It will use a 72-meter-long “floating superstructure” to support two 1 MW turbines.

E.ON to Commission 2500 Digital Transformer Stations

E.ON Digital Transformer Stations modernize distribution grids with smart grid monitoring, voltage control, and remote switching, enabling bidirectional power flow, renewables integration, and rapid fault isolation from centralized grid control centres.

 

Key Points

Remotely monitored grid nodes enhancing smart grid stability and speedier fault response.

✅ Real-time voltage and current data along feeders and laterals

✅ Remote switching cuts outage duration and truck rolls

✅ Supports renewables and bidirectional power flows

 

E.ON plans to commission 2500 digital transformer stations in the service areas of its four German distribution grid operators - Avacon, Bayernwerk, E.DIS and Hansewerk - by the end of 2019. Starting this year, E.ON will solely install digital transformer stations in Germany, aligning with 2019 grid edge trends seen across the sector. This way, the digital grid is quite naturally being integrated into E.ON's distribution grids.

With these transformer stations as the centrepiece of the smart grid, it is possible to monitor and control using synchrophasors in the power grid from the grid control centre. This helps to maintain a more balanced utilisation of the grid and, with increasing complexity, ensures continued security of supply.

Until now, the current and voltage parameters required for safe grid operation could usually only be determined at the beginning of a power line, where there is usually a grid substation in place. Controlling current flow and voltage in the downstream system was physically impossible.

In the future, grids will have to function in both directions: they will bring electricity to the customer while at the same time collecting and transmitting more and more green electricity via HVDC technology where appropriate. This requires physical data to be made available along the entire route. To ensure security of supply, voltage fluctuations must be kept within narrowly defined limits and the current flow must not exceed the specified value, while reducing line losses with superconducting cables remains an important consideration. To manage this challenge, it is necessary to install digital technology.

The possibility of remotely controlling grids also reduces downtimes in the event of faults and supports a smarter electricity infrastructure approach. With the new technology, our grid operators can quickly and easily access the stations of the affected line. The grid control centres can thus limit and eliminate faults on individual line sections within a very short space of time.

Energy experts: US electric grid not designed to withstand the impacts of climate change

Summer Power Grid Reliability and Climate Risk drives urgent planning as extreme heat, peak demand, drought, and aging infrastructure strain ERCOT, NERC regions, risking outages without renewables integration and climate-informed grid modeling.

 

Key Points

Assessment of how extreme weather and demand stress the US grid, informing climate-smart planning to reduce outages.

✅ Many operators rely on historical weather, not climate projections

✅ NERC flags elevated blackout risk amid extreme heat and drought

✅ Renewables and storage can boost capacity and cut emissions

 

As heat ramps up ahead of what forecasters say will be a hotter than normal summer, electricity experts and officials are warning that states may not have enough power to meet demand in the coming months. And many of the nation's grid operators are also not taking climate change into account in their planning, despite available grid resilience guidance that could inform upgrades, even as extreme weather becomes more frequent and more severe.

Power operators in the Central US, in their summer readiness report, have already predicted "insufficient firm resources to cover summer peak forecasts." That assessment accounted for historical weather and the latest NOAA outlook that projects for more extreme weather this summer.

But energy experts say that some power grid operators are not considering how the climate crisis is changing our weather — including more frequent extreme events — and that is a problem if the intent is to build a reliable power grid while accelerating investing in carbon-free electricity across markets.

"The reality is the electricity system is old and a lot of the infrastructure was built before we started thinking about climate change," said Romany Webb, a researcher at Columbia University's Sabin Center for Climate Change Law. "It's not designed to withstand the impacts of climate change."

Webb says many power grid operators use historical weather to make investment decisions, rather than the more dire climate projections, simply because they want to avoid the possibility of financial loss, even as climate-related credit risks for nuclear plants are being flagged, for investing in what might happen versus what has already happened. She said it's the wrong approach and it makes the grid vulnerable.

"We have seen a reluctance on the part of many utilities to factor climate change into their planning processes because they say the science around climate change is too uncertain," Webb said. "The reality is we know climate change is happening, we know the impact it has in terms of more severe heatwaves, hurricanes, drought, with recent hydropower constraints in British Columbia illustrating the risks, and we know that all of those things affect the electricity system so ignoring those impacts just makes the problems worse."

An early heatwave knocked six power plants offline in Texas earlier this month. Residents were asked to limit electricity use, keeping thermostats at 78 degrees or higher and, as extreme heat boosts electricity bills for consumers, avoid using large appliances at peak times. The Electric Reliability Council of Texas, or ERCOT, in its seasonal reliability report, said the state's power grid is prepared for the summer and has "sufficient" power for "normal" summer conditions, based on average weather from 2006 to 2020.

But NOAA's recently released summer outlook forecasts above average temperatures for every county in the nation.

"We are continuing to design and site facilities based on historical weather patterns that we know in the age of climate change are not a good proxy for future conditions," Webb said.

When asked if the agency is creating a blind spot for itself by not accounting for extreme weather predictions, an ERCOT spokesperson said the report "uses a scenario approach to illustrate a range of resource adequacy outcomes based on extreme system conditions, including some extreme weather scenarios."

The North American Electric Reliability Corporation, or NERC — a regulating authority that oversees the health of the nation's electrical infrastructure — has a less optimistic projection.

In a recent seasonal reliability report, NERC placed Texas at "elevated risk" for blackouts this summer. It also reported that while much of the nation will have adequate electricity this summer, several markets are at risk of energy emergencies.

California grid operators, who recently avoided widespread rolling blackouts as heat strained the grid, in its summer reliability report also based its readiness analysis on "the most recent 20 years of historical weather data." The report also notes the assessment "does not fully reflect more extreme climate induced load and supply uncertainties."

Compounding the US power grid's supply and demand problem is drought: NERC says there's been a 2% loss of reliable hydropower from the nation's power-producing dams. Add to that the rapid retirement of many coal power plants — all while nearly everything from toothbrushes to cars are now electrified. Energy experts say adding more renewables into the mix will have the dual impact of cutting climate change inducing greenhouse gas emissions but also increasing the nation's power supply, aligning with efforts such as California's 100% carbon-free mandate that aim to speed the transition.

Two huge wind farms boost investment in America’s heartland

MidAmerican Energy Wind XI expands Iowa wind power with the Beaver Creek and Prairie farms, 169 turbines and 338 MW, delivering renewable energy, grid reliability, rural jobs, and long-term tax revenue through major investment.

 

Key Points

MidAmerican Energy Wind XI is a $3.6B Iowa wind buildout adding 2,000 MW to enhance reliability, jobs, and tax revenue.

✅ 169 turbines at Beaver Creek and Prairie deliver 338 MW.

✅ Wind supplies 36.6 percent of Iowa electricity generation.

✅ Projects forecast $62.4M in property taxes over 20 years.

 

Power company MidAmerican Energy recently announced the beginning of operations at two huge wind farms in the US state of Iowa.

The two projects, called Beaver Creek and Prairie, total 169 turbines and have a combined capacity of 338 megawatts (MW), enough to meet the annual electricity needs of 140,000 homes in the state.

“We’re committed to providing reliable service and outstanding value to our customers, and wind energy accomplishes both,” said Mike Fehr, vice president of resource development at MidAmerican. “Wind energy is good for our customers, and it’s an abundant, renewable resource that also energizes the economy.”

The wind farms form part of MidAmerican Energy’s major Wind XI project, which will see an extra 2,000MW of wind power built, and $3.6 billion invested amid notable wind farm acquisitions shaping the market by the end of 2019. The company estimates it is the largest economic development project in Iowa’s history.

Iowa is something of a hidden powerhouse in American wind energy. The technology provides an astonishing 36.6 percent of the state’s entire electricity generation and plays a growing role in the U.S. electricity mix according to the American Wind Energy Association (AWEA). It also has the second largest amount of installed capacity in the nation at 6917MW; Texas is first with over 21,000MW.

Along with capital investment, wind power brings significant job opportunities and tax revenues for the state. An estimated 9,000 jobs are supported by the industry, something a U.S. wind jobs forecast stated could grow to over 15,000 within a couple of years.

MidAmerican Energy is also keen to stress the economic benefits of its new giant projects, claiming that they will bring in $62.4 million of property tax revenue over their 20-year lifetime.

Tom Kiernan, AWEA’s CEO, revealed last year that, as the most-used source of renewable electricity in the U.S., wind energy is providing more than five states in the American Midwest with over 20 percent of electricity generation, “a testament to American leadership and innovation”.

“For these states, and across America, wind is welcome because it means jobs, investment, and a better tomorrow for rural communities”, he added.
