Largest CSP plant in Africa reducing Morocco’s dependency on external power

Noor I, II and III CSP plants are expected to generate 510 MW of power by 2018

Context

Morocco currently depends on external sources for 95 percent of its primary energy needs. Between 2002 and 2012 alone, the country’s energy consumption increased by an average of 7.2 percent. Meanwhile, Morocco’s demand for primary energy is expected to triple, while demand for electricity is set to quadruple by 2030. In response to this, the country has prioritized improving its home-grown power supply under its new 2010 to 2030 energy strategy. One of its aims is to diversify sources of production and generate value (…)Read more

Project snapshot – Ouarzazate  (NOORo I; II and III plants)

Country affected: Morocco
Sector: Renewable energy and power generation
AfDB related financing: €200 million from AfDB (Noor I, II and III); €200 million from the Clean Technology Fund (Noor I, II and III)

Outputs

  • Construction of two concentrated solar power plants with parabolic troughs with 3 hour (Noor I), 7 hour (Noor II),
  • and a concentrated solar power plant with tower 7-8 hour (Noor III) storage capacity

Objectives

Objective

Since 2010, the AfDB, in partnership with the Clean Technology Fund, European Investment Bank, European Union, French Development Agency, Germany Development Bank, Moroccan Agency for Solar Agency and the World Bank, has worked with the Moroccan Solar Energy Program – NOOR – which aims to develop minimum capacity of 2,000 MW by 2020 in order to secure power supplies for the population and productive sectors of the economy. The construction of the first 160 MW solar power station (Noor I) began in 2013 and is scheduled (…)Read more

Key Facts

  • The project is one of the largest concentrated solar plants in the world.
  • It utilizes an innovative financing structure which leverages the capacity of a consortium of independent power producers to sell the power generated by the plant back to the government in a public-private partnership arrangement.
  • The project’s financing support mechanism will bring down the capital cost of the concentrated solar power to levels comparable with traditional technologies and the wholesale cost of power in Morocco.
  • It is expected to reduce the concentrate solar power global cost curve by 3 percent.

Impact

  • Reduction in the country’s energy dependence through the additional production of: 160 MW power generation expected by end 2015 from Noor I and an additional 350 MW power generation expected by end 2018 from Noor II and Noor III
  • Reduction in CO2 emissions by 762,000 tons per year, or 19 million tons over 25 years from Noor I, II and III
  • Realization of its 42 percent renewable energy objective in its energy mix by 2020 and the development of a local renewable energy industry
  • 250 permanent jobs and 2,400 temporary jobs created during construction of Noor I and additional employment expected from construction of Noor II and IIIThe following valuable lessons were learned during Noor I which are being used to improve the relevant processes of Noor II and Noor III

Lessons Learned

Optimizing plant design supplies more power and increases revenue. Technical design should be based on a minimum of peak hour demand in addition to minimum levels of storage required, not only on a set amount of thermal storage alone. By optimizing plant design to meet both prerequisites, bidders are provided the flexibility to explore innovative approaches to meeting the requirements, while minimizing the amount of thermal storage needed, which could also significantly impact the plant’s capital costs.

Shave off as much as a year in procurement time by including draft legal documents for bidders. In the case of Noor I, the process to develop and negotiate the related legal agreements that followed award of the project took over a year. Including sample legal agreements from past similar projects for bidders to review and comment upon during the procurement process may therefore save a lot of time compared to starting the discussions only once a bid has been awarded.

Undertaking the bulk of the environmental and social impact assessment during the procurement process saves additional time. The plant-specific environmental and social impact assessment for Noor I was started after award of the project and took considerable time. To accelerate this process, terms of reference for consultants to be hired by bidders to undertake most of the assessment during the procurement process should be included in the bidding documents. Bidders are then required to submit a draft of the assessment as part of their final bids. Once the bidder(s) have been selected, they can then begin their public consultation process and subsequently disclose the assessment(s), after Bank review, for the requisite disclosure period.
