6 FAQs about [Morocco mine shaft energy storage]
Who is responsible for electricity storage in Morocco?
Electricity storage in Morocco falls within the scope of competence of the Ministry of Energy, Mines, Water and Environment. ONEE is in charge of the production, the transmission and the distribution of electricity.
How is energy storage defined in Morocco?
Electricity storage is not separately defined in the Moroccan legislative framework. The rules concerning the issue of energy storage are to be found in the law applicable to the production of electricity.
Will Morocco develop a second hydro pumped storage project?
The Moroccan Government intends to develop a second hydro pumped storage project with a capacity of 360 MW, called “STEP Abdelmoumen”, near Agadir 3 , which is expected to become operational in 2020. Moreover, the second and third phases of the Noor project are currently being developed by MASEN, the Moroccan Agency for Solar Energy.
What are Morocco's energy policy initiatives?
Beyond the advancement of renewable energy, Morocco’s policy initiatives encompass energy efficiency measures in challenging-to-abate sectors, such as building insulation and the adoption of energy-saving light bulbs. The overarching objective is to achieve a 20% reduction in overall energy consumption by 2030.
Should Morocco co-locate PV and CSP and share CSP thermal storage?
This idea of colocating PV and CSP and sharing the CSP thermal storage is one that Schmitz believes will be widely applicable as energy grids become more saturated with renewables, not just Morocco’s, and as therefor more regulators move from lowest cost to “best fit” procurement.
What are the challenges faced by electricity storage in Morocco?
Electricity storage is still at a development stage in Morocco and therefore faces the following challenges: Lack of a specific legislation regulating electricity storage – the question of storage will be dealt on a case by case basis.
