Polaris solar PV net news: recently, Saudi Arabia’s Energy Minister KhalidAlFalih announced that Saudi Arabia will launch in the next few weeks the new renewable energy tenders. According to reports, the tender is divided into three phases, the first phase includes installed capacity respectively, 300MW, 400MW of solar and wind power projects, phase II and phase III, including solar-thermal power generation and garbage power generation projects. Among them, solar-thermal power project will build, own and transfer (BOT) model for development.
It is reported that the Saudi’s growing demand for electricity and fresh water demand for storage advantages of solar-thermal power generation provides an important opportunity for development, it can complement and photovoltaic power generation, promote Saudi of renewable energy development.
According to the King Abdullah University of science and technology-related figures, in order to meet domestic energy needs, the country consumed every day crude oil output of the country 25% that day (around 2.8 million barrels a day).
At present, the Government of Saudi Arabia is trying to reduce its reliance on fossil fuels, and is committed to diversification of the economic and social development in 2030. Specific plans include, by 2020, renewable energy installed capacity 3.5GW goal by 2023, 9.5GW by 2030 total $50 billion Fund for investment in solar power and wind power projects.
According to King Abdullah, Atomic and renewable energy Department data shows, Saudi Hagl, Umluj, Duba, AlWajh and Timaa, the Northwest Territories, DNI index amounted to approximately 1805kWh/m2/yr, while in the Tabuk region, around DNI index as high as 2047kWh/m2/yr.
“Can be understood to be, preferred layout of photovoltaic and wind turbine construction speed may be relatively quickly, to meet peak demand for electricity, but I would like to see solar-thermal power generation play their stored energy advantages, and further optimize the energy structure. “Saudi ACWAPower CEO PaddyPadmanathan said.
Solar thermal power generation or to meet the growing demand for electricity
According to the Saudi electricity company (SEC) according to the data provided, the country due to heavy use of air conditioning in summer electricity demand growth, annual growth rate of 7%~9%.
In August 2015, the peak load of the power companies hit a record high, up to 62.3GW, about 10.2% peak of the year than in the past.
Saudi power relies heavily on fossil fuels, according to the Saudi electricity and cogeneration regulatory authority (ECRA) data show 2014 Saudi electricity production accounted for: crude oil 44%, 11% diesel, heavy fuel oil 13% and gas 32%.
Meanwhile, falling PV costs to expand the photovoltaic and solar thermal power generation cost gap between, prompting solar thermal project developers focus more on solar thermal power generation energy advantage. Although PV can help meet the peak demand of the day, but solar-thermal power plants can achieve a 24-hour electricity.
GE renewable energy General Manager regenerative steam power plant StevenJ.Moss, hybrid power project of PV installed capacity increased, flexible led to power generation to meet the night electricity demand and the increased demand for long storage. At present, many solar photovoltaic and solar thermal power tender, tends to be combined, or sought to expand storage.
For example, Moroccan NoorMidelt1 solar hybrid power project is a collection of solar-thermal power and photovoltaic technologies as one of the hybrid power station, total installed capacity up to 400MW; in addition, Dubai is also planning MohammedbinRashidAlMaktoum solar Park, for now, PV installed capacity up to 1GW, phase I installed capacity of 200MW solar thermal project-related work has started.
According to StevenJ.Moss introduced, in areas with abundant solar energy resources, realization of photovoltaic and solar thermal well to complement each other. They can also carry out construction, respectively, an independent bid, tender addition to the pursuit of the lowest cost per kilowatt, also needs to have the appropriate regulatory body to ensure that the installed capacity of the balance.
Solar thermal power generation cost is the key
It is learned that solar thermal power generation project developers have deployment of building integrated solar combined cycle power plant in Saudi Arabia (ISCC), while SEC was working to make Duba1 and WaadAlShamal installation costs of solar thermal power stations at a relatively low level (less than $1.6/MW). Currently, GE supply steam turbines for the Duba1 project has arrived at the scene, and the WaadAlShamal project is in the midst of intense construction.
It is understood that the SEC for the ISCC project provides some financial support, but need high current power station construction costs are not fully in place. In addition, due to fierce competition, many solar-thermal power plant developers tried to improve plant performance and improve the supply chain to reduce further the cost of investment.
In May 2016, on the MENASol2016 Forum, held in Dubai, Saudi Aramco (SaudiAramco) renewable energy Chief TimPolega said they expect over the next 10 years, a 6 hour storage system of solar-thermal power plant construction costs fell sharply from 2016 to $5.32/W (about 36.6 Yuan/W) by 2021, will fall to $4.28/W (about 29.4/W) By 2026, is expected to fall to $3.80/W (about 26.1 Yuan/W).
However, Polega also said future use battery energy storage photovoltaic power generation costs will fall further, or make the storage advantages of solar-thermal power generation is no longer so obvious.
In fact, the wider layout is the key to reducing costs of solar thermal power generation market, and solar-thermal power generation industry in China is now in a critical period of development, the market prospects. And China plan to be completed by the end of 2018, the first batch of 20 solar thermal demonstration project of construction, total installed capacity up to 1.4GW.
“I think China will be a game-changer and optical-thermal power generation costs have a significant impact. “Padmanathan said.
Last month, the Dubai electricity and water authority (DEWA) has launched its first 200MW solar-thermal project (first phase of the Mohammed bin Rashid Al Maktoum solar Park project) tender. In 2016, the DEWA has set global minimum price of PV, and first solar-thermal power plants offer a globally competitive price-around $80/MWh (about 0.55 Yuan per kWh).
The perfect combination of solar thermal power generation and sea water desalination
In addition to power generation, desalination is also Saudi Arabia’s major potential market development of solar-thermal power generation technology.
It is understood that the Saudi desalination Corporation (SWCC) has 29 desalination plants, seawater desalination plant for the production of desalinated water desalination capacity the country around 62%, but these projects total power electrical equipment up to 7.3GW.
SWCC data shows from 2007 to 2015, demand for fresh water in Saudi Arabia grew at an annual rate of 5.5%.
“Solar thermal power generation technique is very suitable for seawater desalination in Saudi Arabia. Tabuk (located in Northwest Saudi Arabia) in some areas, such as, solar desalination of sea water up to 75% per cent. “Taqnia energy, senior business development manager WailBamhair said.
Padmanathan said: “We firmly believe that solar thermal power generation technology combined with conventional fossil fuels in Saudi Arabia is very fit and very necessary, which can give full play to its advantage for energy storage, and to meet the Saudi demand for electricity at night, and can also provide heat for desalination systems. ”
