Skytron® energy has been selected to fit out one of the largest solar power plants on the African continent with its monitoring, control and supervision technology. The Mulilo Sonnedix Prieska Photovoltaic (PV) plant will be completed in July 2016, with a capacity of 86.2 megawatts (MWp). The plant is located just outside Prieska, in the high-lying Northern Cape region and will provide approximately 30,000 homes with clean energy.
skytron energy understands and fulfills the special grid standards in South Africa, which are required by the public electricity company ESKOM. While its power plant controller skycontrol ensures high-precision measurement of all relevant physical quantities at the grid connection point, their continuous feedback to the controller input and the required feed-in tuning of active and reactive power, PVGuard® visualizes and analyzes all relevant data in real time.
“With more than 2,500 hours of sunlight reaching South Africa a year solar power is an ideal source of energy in the region,” says Lino Garcia, the Director Business Development of skytron energy “. “Considering the negative impact of load-shedding and rising energy prices, on the South African economy over the past decades, we are very happy to finally see changes and an increased awareness of renewable energies. Besides being environmentally friendly, PV plants are, first and foremost, reliable and cost effective sources of electricity. In order to meet local requirements and maintain the highest possible standards at the Prieska power plant, we will both integrate the entire range of our high-quality control and supervision technology and redesign components for the site.”
“We value the flexibility in skytron energy’s monitoring technology and the fact that the company adapts its products to our needs,” says Andre Steffen, the Senior Project Manager of juwi Renewable Energies. “Considering the particular local requirements in South Africa, we selected skytron energy as the best partner to fulfill such needs for the Prieska project. Beyond its state-of-the-art technology, we were also impressed by its highly experienced team.”
Prieska is one of the utility-scale photovoltaic projects approved by South Africa’s Renewable Energy Independent Power Producers Procurement Programme (REIPPPP), which calls for the development of 18 gigawatts (GW) of renewable energy by 2030, 8.4 GW of which has been allocated to solar power. The new facility is a major milestone in the development of PV energy in the region.
The plant in the Northern Cape is equipped with the entire technology fleet of skytron energy, which results in the highest possible performance of the plant: the SCADA software PVGuard, the power plant control system skycontrol, the on-site skylog data logger system, the on-site data server skyserv, 600 ArrayGuard® FH combiner boxes and several skyCONNi-Sun universal weather units. Altogether, they cover the entire power plant and ensure highest plant performance and output for investors. The manufacturing of the combiner boxes with integrated string current monitoring was contracted to a local partner to ensure that the system meets the local content requirements by REIPPPP (and are specially designed to suit the region’s climatic conditions. The South African manufacturing line and test facilities were audited by skytron energy to guarantee its high quality standards.
Are the UK Governments Plans for the Energy Sector Smart?
The revolution in the energy sector marches on, wind turbines and solar panels are harnessing more renewable energy than ever before – so where is it all leading?
The UK government have recently announced plans to modernise the way we produce, store and use electricity. And, if realised, the plans could be just the thing to bring the energy sector in line with 21st century technology and ideologies.
Central to the plans is an initiative that will see smart meters installed in homes and businesses the length and breadth of the country – and their aim? To create an environment where electricity can be managed more efficiently.
The news has prompted some speculation about how energy suppliers will react and many are predicting a price war. This could benefit consumers of electricity and investors, many of whom may be looking to make a profit by trading energy company shares online using platforms such as Oanda – but the potential for good news doesn’t end there.
Introducing New Technology
The plan, titled Smart Systems and Flexibility is being rolled out in the hope that it will have a positive impact in three core areas.
- To offer consumers greater control by making smart meters available for all homes and businesses by 2020. Energy users will be able to monitor, control and record the amount of energy they use.
- Incentivise energy suppliers to change the manner in which they buy electricity, to offer more smart tariffs and more off-peak periods for energy consumption.
- Introduce new standards for electrical appliances – it is hoped that the new wave of appliances will recognise when electricity is at its cheapest and at its most expensive and respond accordingly.
How the Plans Will Affect Solar Energy
Around 7 million houses in the UK have solar panels and the government say that their plan will benefit them as they will be able to store electricity on batteries. The stored energy can then be used by the household and excess energy can be exported to the national grid – in this instance lower tariffs or even payment for the excess energy will bring down annual costs significantly.
The rate of return on energy exported to the national grid is currently between 6% and 10%, but there are many variables to take into account, such as, the cost of battery storage and light levels. Still, those with state-of-the-art solar electricity systems could end up with an annual profit after selling their excess energy.
The Internet of Things
Much of what the plans set out to achieve are linked to the now ubiquitous “internet of things” – where, for example, appliances and heating systems are connected to the internet in order to make them function more smartly.
Companies like Hive have already made great inroads into this type of technology, but the road that the government plans are heading down, will, potentially, go much further -blockchain technology looms and has already proved to be a game changer in the world of currency.
It has already been suggested that the peer to peer selling of energy and exporting it to the national grid may eventually be done using blockchain technology.
“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.”
Don and Alex Tapscott, Blockchain Revolution (2016)
The upshot of the government’s plans for the revolution of the energy sector, is that technology will play an indelible role in making it more efficient, more flexible and ultimately more sustainable.
4 Case Studies on the Benefits of Solar Energy
Demand for solar energy is growing at a surprising rate. New figures from SolarPower Europe show that solar energy production has risen 50% since the summer of 2016.
However, many people are still skeptical of the benefits of solar energy.Does it actually make a significant reduction in our carbon footprint? Is it actually cost-effective for the company over the long-run?
A number of case studies have been conducted, which indicate solar energy can be enormously beneficial. Here are some of the most compelling studies on the subject.
1. Boulder Nissan
When you think of companies that leverage solar power, car dealerships probably aren’t the first ones that come to mind. However, Boulder Nissan is highly committed to promoting green energy. They worked with Independent Power Systems to setup a number of solar cells. Here were the results:
- Boulder Nissan has reduced coal generated electricity by 65%.
- They are on track to run on 100% renewable energy within the next 13 years.
- Boulder Nissan reduced CO2 emissions by 416,000 lbs. within the first year after installing their solar panels.
This is one of the most impressive solar energy case studies a small business has published in recent years. It shows that even small companies in rural communities can make a major difference by adapting solar energy.
2. Valley Electric Association
In 2015, the Valley Electric Association (VEA) created an 80-acre solar garden. Before retiring from the legislature, U.S. Senate Minority Leader Harry Reid praised the new project as a way to make the state more energy dependent and reduce our carbon footprint.
“This facility will provide its customers with the opportunity to purchase 100 percent of their electricity from clean energy produced in Nevada,” Reid told reporters with the Pahrump Valley Times. “That’s a step forward for the Silver State, but it also proves that utilities can work with customers to provide clean renewable energy that they demand.”
The solar energy that VEA produced was drastically higher than anyone would have predicted. SolarWorld estimates that the solar garden created 32,680,000 kwh every year, which was enough to power nearly 4,000 homes.
This was a major undertaking for a purple state, which may inspire their peers throughout the Midwest to develop solar gardens of their own. It will reduce dependency on the electric grid, which is a problem for many remote states in the central part of the country.
3. Las Vegas Casinos
A number of Las Vegas casinos have started investing in solar panels over the last couple of years. The Guardian reports that many of these casinos have cut costs considerably. Some of them are even selling the energy back to the grid.
“It’s no accident that we put the array on top of a conference center. This is good business for us,” Cindy Ortega, chief sustainability officer at MGM Resorts told Guardian reporters. “We are looking at leaving the power system, and one of the reasons for that is we can procure more renewable energy on the open market.”
There have been many benefits for casinos using solar energy. They are some of the most energy-intensive institutions in the world, so this has helped them become much more cost-effective. It also helps minimize disruptions to their customers learning online keno strategies in the event of any problems with the electric grid.
4. Boston College
Boston College has been committed to many green initiatives over the years. A group of researchers experimented with solar cells on different parts of the campus to see where they could produce the most electricity. They discovered that the best locationwas at St. Clement’sHall. The solar cells there dramatically. It would also reduce CO2 emissions by 521,702 lbs. a year and be enough to save 10,869 trees.
Boston College is exploring new ways to expand their usage of solar cells. They may be able to invest in more effective solar panels that can generate far more solar energy.
