10. Robert-Bourassa
La Grande, Canada
This plant is part of Quebec’s James Bay Project and has a generating capacity of 5,616 MW. The dam is named after Premier of Quebec Robert Bourassa and was originally commissioned in 1981.

9. Krasnoyarsk
Yenisei River, Russia

This dam originally came online in 1972 and has been operating ever since. It’s located in Southern Russia and has a generating capacity of 6,000 MW.

8. Longtan Dam
Hongshui River, China

The Longtan Dam is the tallest of its type in the world and has a generating capacity of 6,426 MW. It’s relatively new, as it was only commissioned in 2007.

7. Grand Coulee
Columbia River, United States

Washington State’s Grand Coulee dam is a classic. It’s been around since 1933 and remains one of the biggest in the world. It has a generating capacity of 6,809 MW and is currently undergoing major overhauls.

6. Xiangjiaba
Jinsha River, Cina

This dam operates on a tributary of the Yangtze River and has a generating capacity of 6,400 MW. This dam is also very new, beginning operations in 2012.

5. Tucuruí
Tocantins River, Brazil

This dam was the first large-scale hydro power project in the Amazon rainforest. It was commissioned in 1984 and has a generating capacity of 8,370 MW.

4. Guri
Caroní River, Venezuela

The Guri Dam is huge. It is 7,426 meters long and 162 meters high. It’s also quite old, as it was commissioned in 1978. It currently has a generating capacity of 10,235 MW.

3. Xiluodu
Jinsha River, China

This dam has a generating capacity of 13,860 and also provides flood control for the region. It’s brand new, as it was only commissioned in 2013, and is operated by China Yangtze Power.

2. Itaipu Dam
Paraná River, Brazil/Paraguay

This dam occasionally has a higher generating output than the number one spot. With 14 GW of installed capacity it’s quite impressive. It also straddles the line between two countries, making initial negotiations difficult.

1. Three Gorges Dam
Yangtze Rvier, China

Here it is: the big one. With a massive generating capacity of 22.5 GW, the Three Gorges Dam is the biggest hydro dam in the world. China had begun dreaming up this dam in 1919, and in 2008, it came alive. It’s a beast of a hydro dam and is a marvel of modern engineering.

Energy Digital sets out Gartner’s Top 10 ways organisations can prepare for a pandemic, via effective operational risk management. 

As the spread of the Coronavirus (COVID-19) continues to develop, many businesses are left uncertain as to whether their risk mitigation plan is sufficient. 

In a recent webinar conducted by the research and advisory firm just 12% of 1,500 people believe that their business is highly prepared for the impact of COVID-19, while 56% believed themselves to be somewhat prepared, and 11% believed themselves to be very unprepared. 

“Most organizations have done some pandemic planning but still have many unanswered questions about whether they have done everything they can to manage risks,” says Jim Mello, Senior Director, Advisory, Gartner. 

Establish a preparedness framework

Establish a team that represents all critical business functions. These people will report directly to executive management and are responsible for prioritising the importance of business activities and organise them in tiers for response and recovery.

Monitor the situation

It is important to ensure that organisations monitor the rate in which the infection is spreading and its severity. Many rely on the World Health Organisation for information.

Revise finance

Be sure to revise revenue forecasts and communicate with investors, as well as suppliers in regards to any potential finance issues. It is important to ensure that the business has the working capital to ride it out. 

Ways to ensure this include: working capital checks, seeking loans or government-sponsored financial relief.

Extend personal hygiene and cleaning protocols

It is important to comply with any changes to workplace regulations. In addition, it is important to establish protocols for staff returning from infected areas, as well as extending existing hygiene activities.

Review HR 

Ensure close monitoring of absenteeism rates for signs of problems. It is important to identify critical staff in order to make sure the company can continue to function in their absence and be prepared for up to 40% absentee rates.

In addition to reviewing HR policies and procedures, it is important to maintain a level of sensitivity when it comes to engaging with employees and workplace preferences.

Establish a communication programme

People can feel out of the loop quickly. Establish a spokesperson appropriate for the situation who can maintain lines of communication. In addition, organisations should establish pre-approved messages and scripts for various stakeholders.

Review the impact on the operation

Although this may seem overwhelming, the team established to represent all critical business functions should identify key areas to consider. It is important to maintain a connection with the reality on the ground in countries affected.

Key questions to consider: is transport functioning? Have holidays been extended? Where can operation continue and where do they need to stop?

Review IT 

IT business functions tend to be relatively well-prepared for business continuity. However, it is important to assess the supply chain for critical equipment and keep extra inventory if required.

In addition, organisations should keep in mind remote data centre management and cloud options for critical systems as well as enabling remote working programs and rescheduling any non-essential IT work prioritising key applications. 

Review pandemic plans to identify any gaps in response

Conduct a preparedness exercise by validating roles and responsibilities as well as recovery requirements and procedures, in order to identify any gaps in the recover capabilities and resource needs.

Review after-action

Following the establishment of a pandemic plan, identify three lessons learned, key observations or improvements for the exercise. After establishing these organisations should priorities the short and long term follow up actions.
