The Juba Solar Power Station is a proposed 20 MW (27,000 hp) solar power plant in South Sudan. The solar farm is under development by a consortium comprising Elsewedy Electric Company of Egypt, Asunim Solar from the United Arab Emirates (UAE) and I-kWh Company, an energy consultancy firm also based in the UAE.
Most of the electricity in the country is concentrated in Juba the capital and in the regional centers of Malakal and Wau. At that time the demand for electricity in the county was estimated at over 300 MW and growing. Nearly all electricity sources in the country are fossil-fuel based, with attendant challenges of cost and environmental pollution.
The solar farm will have an attached battery energy storage system rated at 35MWh. The off-taker is the South Sudanese Ministry of Electricity, Dams, Irrigation and Water Resources, represented by South Sudan Electricity Corporation, the national electric utility parastatal company.
This power station is an attempt to (a) diversify the country's generation mix (b) increase the country's generation capacity and (c) increase the number of South Sudan's homes, businesses and industries connected to the national grid. The power station is reported to cost an estimated US$45 million to construct.
For certain projects, backup power must be provided for the BESS auxiliary load as required by the BESS supplier or fire codes. Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation.
Project owners are also responsible for the electricity costs associated with the BESS auxiliary load during operation. The electricity cost for auxiliary loads depends on the energy consumption (kWh) and the pricing structure set by independent system operators or utilities. For example:
Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation. BESS fire safety standards, such as NFPA 855, outline minimum requirements for backup power for fire safety systems.
If a BESS product cannot meet these backup power requirements as mandated by the code or the Authority Having Jurisdiction (AHJ), an external backup power source needs to be provided. Options for backup power include local distribution network feeders (if available with sufficient kVA rating) or backup generators.
In the early 2000s, Germany encouraged people to install solar panels on the roofs of their homes by rewarding them with payments, known as feed-in tariffs, for sending energy to the grid. But those have become less lucrative in recent years, making such large-scale investments less attractive.
But in homes across Germany, they are powering a quiet transformation, bringing the green revolution into the hands of people without requiring them to make a large investment, find an electrician or use heavy tools. “You don’t need to drill or hammer anything,” Ms. Berg said.
History of German feed-in tariffs in ¢/kWh for rooftop solar of less than 10 kW p since 2001. For 2016, it amounted to 12.31 ¢/kWh. Germany introduced its feed-in tariff in 2000 and it later became a model for solar industry policy support in other countries. : 145
Solar power in Morocco is enabled by the country having one of the highest rates of solar insolation among other countries— about 3,000 hours per year of sunshine but up to 3,600 hours in the desert. Morocco has launched one of the world’s largest solar energy projects costing an estimated $9 billion.
Morocco has launched one of the world’s largest solar energy projects costing an estimated $9 billion. The aim of the project was to create 2,000 megawatts of solar generation capacity by 2020. The Moroccan Agency for Solar Energy (MASEN), a public-private venture, was established to lead the project.
The Moroccan Agency for Solar Energy invited expressions of interest in the design, construction, operation, maintenance and financing of the first of the five planned solar power stations, the 500 MW complex in the southern town of Ouarzazate, that includes both PV and CSP.
Morocco has a power cable link to Europe, the Spain-Morocco interconnection, rated at 900 MW when going from Spain to Morocco and 600 MW when going from Morocco to Spain. This is the first electric interconnection built between Africa and Europe.
