Empowering Variable Renewables Options for Flexible Electricity Systems

| March 19, 2018

Increasing the share of renewables in energy portfolios is key to reducing global CO2 emissions. Variable renewables, such as wind, wave, tidal, solar and run-of-river hydro, share a characteristic that distinguishes them from conventional sources of energy: their output varies according to the availability of the resource. This variability represents an additional challenge in terms of their integration in power systems. However, if a power system is sufficiently flexible, the significance of variability is reduced. A flexible electricity system is one that can respond reliably and rapidly to large fluctuations in supply and demand. Some flexibility already features in electricity systems: in the generation portfolio, in markets, in transmission and distribution, and in the shape of electricity demand.

More Solar Ready To Help Power Pumping For SA Water

Article | April 29, 2021

SA Water’s electricity supply is about to become greener and cheaper again with the addition of another major solar power system, and an even bigger installation to soon follow. The utility says more 7,300 solar panels installed at the second pump station on its pipeline between Swan Reach and Stockwell are now connected and ready to go. “The Swan Reach to Stockwell Pipeline spans across more than 50 kilometres inland from the mighty Murray across to the northern Barossa area, and therefore requires significant energy to pump clean, safe drinking water across such large distances,” said SA Water’s Nicola Murphy While the total capacity of this new solar farm wasn’t provided, Ms. Murphy said it will generate approximately 5,224 megawatt hours of clean, green energy annually. There’s more solar energy to come for this section of pipeline, with a further 16,000 panels currently being connected at the first pump station.

Here are the Best Ways to Optimize Your Solar Power

Article | April 8, 2020

Let’s take a look at the common case. It’s not a secret that we charge our devices for work or study at the office or at uni. When we are asked to do everything from home, we must use our own electricity to power our essential devices for work. Without even realizing, we also need to turn on the heater or AC to keep ourselves in comfortable temperature. Plus, there will be a time when we are tempted to turn on the TV, Xbox or PlayStation, for fun. In short, the more power we consume, the more expensive the bill we will pay! If we rely on solar energy, our system will get us covered. During the day, our solar PV will produce the most electricity we use at home. So, even if we are spending all day working or studying, we won’t need to pay more for our electricity. Yet, to make sure we can save money as much as possible, we must do it right. To make it easier, our team at Solar Arena has collected the best tips you can follow:

CORONAVIRUS CRISIS FAST-FORWARDS GREEN ENERGY 10 YEARS INTO THE FUTURE

Article | April 6, 2020

As businesses shut down and many work from home around the world, electricity demand has reduced in COVID-19 hotspots. This could have a knock-on effect for the renewable sector. China, where the outbreak first took hold, is the world’s biggest electricity consumer. Output from factories has been substantially diminished with many unable to return to their jobs in manufacturing. Due to the curtailing of industrial electricity use, cuts in energy consumption for 2020 could be equivalent to the power used by the whole of Chile, according to IHS Markit. In Europe, peak power consumption has also gone down. Italy, Spain, and the UK have all seen an average 10 per cent drop in energy usage with bars, restaurants, offices and factories, which remain closed as social distancing measures continue.
