10.) Statkraft's Osmotic Power Projects—Norway

Europe's leading renewable energy company, Statkraft is a global pioneer in osmotic energy. Through the natural process of osmosis, fresh water and salt water are guided into separate chambers, divided by an artificial membrane. The pressure of the process generates waterfalls that can be utilized in a power generating turbine. As the company continues working on pilot projects, Statkraft claims that osmotic power has the potential of 1600 to 1700 Twh—nearly the equivalent of China's total electricity consumption.

9.) Andasol—Andalusia, Spain

Alongside an empty mountain plateau in Andalusia, some 600,000 parabolic mirrors are now connected and operating in the world's largest solar power station (150 MW). Located 1,100 meters above sea level, the clear and less turbulent atmosphere allows for the capture of more solar energy than the entire Saudi Arabian peninsula. It's as big as 210 football fields and will generate enough energy for half a million people.

8.) Rance Tidal Power Station—Brittany, France

The world's first tidal power station, located on the estuary of the Rance River, is now the world's second largest tidal power station—after holding the number one spot for 40 years. With an annual output of about 600 Gwh, the station has a peak rating of 240 MW generated by its 24 turbines, and attracts about 200,000 visitors per year.

7.) Solnova Solar Power Station—Sanlucar la Mayor, Spain

As the largest CSP power station in the world, Solnova's plant consists of five separate units of 50 MW each (250 MW total), each owned and operated by Abengoa Solar. Each power station utilizes parabolic troughs, while some are also equipped to support natural gas as a secondary fuel source for power generation.

6.) Sihwa Lake Tidal Power Plant—Sihwa Lake, South Korea

Completed last year, the 254 MW Sihwa Lake Tidal Power Plant is the largest tidal power installation in the world. Ten 25.4 MW submerged bulb turbines are driven in an unpumped flood generation scheme that makes use of a seawall constructed in 1994 for flood mitigation and agricultural purposes.

5.) Solar Energy Generating Systems (SEGS)—California, USA

As the largest solar energy generating facility in the world, SEGS consists of nine solar power plants in California's Mojave Desert with an installed capacity of 354 MW. Additionally, turbines are utilized at night by burning natural gas. According to NextEra, the plant powers over 230,000 homes and displaces 3,800 tons of pollution annually.

4.) Walney Wind Farm—Cumbria, U.K.

With 102 turbines stretching 28 square miles off the coast of Cumbria, the Walney wind farm recently became the world's largest offshore wind facility. However, DONG Energy, a major stakeholder in the project, is also involved in an even larger London Array wind farm, which could produce an upwards of 1000 MW when completed. As of now, the Walney wind farm has a maximum output of 367.2 MW, and involved some of the fastest wind farm construction of its type.

3.) The Tilbury—Tilbury, U.K.

The world's largest biomass-fueled power plant just came online in the UK, generating an upwards of 750 MW of base load renewable power. The new station burns wood pellets to produce electricity and is located on the site of Tilbury's aging coal-fired power plant, which is set to shut down in 2015.

2.) Roscoe Wind Farm—Texas, USA

Among the many large wind farms across the state of Texas, the Roscoe wind farm is the largest, with a capacity of 781 MW. Owned and operated by E.ON Climate & Renewables, the 627 wind turbines were set up in four phases since 2008, costing over $1 billion to supply power to 250,000 homes.

1.) The Geysers—California, USA

The Geysers is a complex consisting of 22 geothermal power plants, drawing steam from over 350 wells, with an active installed capacity of 1517 MW. About 72 miles north of San Francisco, 19 of the 22 plants are owned and operated by Calpine Corporation with the other two under Northern California Power Agency and Silicon Valley Power. Since the activities of one plant affect those around it, the consolidation of plant ownership at the Geysers has been beneficial in allowing the plants to operate cooperatively rather than in their own short-term interest. Currently, the Geysers produce enough electricity for 1.1 million people, but techniques developed from Enhanced Geothermal Systems are expected to increase future production.

Geothermal energy accounts for over 10,000 MW of installed capacity around the world, with the largest capacities in the U.S. (3,086 MW), Philippines and Indonesia.

Top 10 ways to prepare for COVID-19

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.
