Completely subverting the traditional energy demand and realizing that the comprehensive cost of Photovoltaic and Electric energy storage system is lower than that of thermal power. This is the reason why invested heavily by Hillhouse. Photovoltaic and Electric energy storage system will eventually become the mainstream energy source, not necessarily because it is the cleanest, …
As lithium-ion batteries become more and more reliable, it has driven a sharp increase in lithium battery production. Therefore, how to choose a reliable battery manufacturer and how to identify batteries have become crucial. 1. Checking the manufacturer reliability At present, there are more and more lithium battery manufacturers, you can’t be sure whether these …
From 1 January 2022, the grid electricity costs in Belgium will no longer be determined by the total number of kilowatt hours (kWh) consumed, but by the peak power demanded from the grid. This is the so-called capacity tariff (also known as demand charge). The “demand charge” are the costs for constructing, managing and maintaining …
What is the demand charge? Typically, there are three parts to commercial energy bills. Baseline Charge, often known as the connection fee. This is typically a set fee that everyone pays just to be part of the grid. Energy or usage charge is based on the total amount of electricity you use. While demand charge …
Recently, the solar feed-in tariffs in Australia and New Zealand have decreased significantly. According to the report from PV Magazine, Victoria’s Essential Services Commission decided to decrease the minimum solar feed-in tariffs in Victoria from the current 10.2 cents/kWh to 6.7 cents/kWh, shrinking around 34% from July of 2021. Meanwhile, according to the legislative suggestions …
As we know, it’s inevitable that human beings emit carbon. If we cannot reduce, we absorb it. Carbon neutrality is very important if we want to avoid climate disasters. Carbon neutrality means making a balance between emitting and absorbing carbon from the atmosphere in #carbonsinks, which is a system that absorbs more carbon than it …
Micro-grid shares all functions of VPP, yet it differentiates itself from VPP through some unique features. 1.Unlike VPP, micro-grid could be disconnected from the main grid and become the islands of power. 2.VPP covers wider space as it is flexible to expand or shrink the operating area, while micro-grid, on the opposite, has very defined …
What is micro-grid and how is it different from VPP? Read More »
Virtual power plant is a power plant based on software instead of physical factory. VPP connects many DERs to form an energy network. Meanwhile, it allows bi-directional power flow between utility, commercial as well as residential end users. Not only helping end users make profit by feeding their renewable energy into the network, VPP also …
A Distributed Energy Resource (DER) is any resource on the distribution system that produces electricity. To make it simply, if you have installed a renewable energy generator in your house, your house has automatically become a DER. Distributed energy resources include the following types of embedded generators: Turbines-Gas, Wind, Hydro-electric Solar Photovoltaic(PV) System Diesel or …
A battery’s power is how fast it can be charged or discharged. You can find the related information in the product datasheet. For example, in the datasheet of Sixclocks-BESS3, the battery max. charging/discharging current is 1C which means it can discharge all its usable energy in 1 hour. As for another battery of Sixclocks-BESS288100, the …
