Morocco Expands Concentrated Solar Power to Deliver Clean Energy After Sunset
Morocco continues to strengthen its renewable energy leadership by expanding Concentrated Solar Power (CSP) projects that generate electricity even after sunset. Unlike traditional photovoltaic (PV) solar panels, CSP plants use thousands of mirrors to concentrate sunlight onto a central receiver, producing intense heat that is stored in molten salt for later use.
This thermal energy storage allows CSP plants to continue producing electricity during the evening and nighttime, improving grid reliability and reducing dependence on fossil fuel power plants. Morocco's investment in this technology demonstrates how renewable energy can provide dependable electricity around the clock.
📌 Key Takeaways
- Country: Morocco
- Technology: Concentrated Solar Power (CSP)
- Sector: Solar Thermal Energy
- Primary Benefit: Renewable electricity after sunset
- Energy Storage: Molten Salt Thermal Storage
💡 Did You Know?
Some Concentrated Solar Power plants can continue generating electricity for up to 10–15 hours after sunset using molten salt thermal storage, making solar power more reliable even when the sun is no longer shining.
What Is Concentrated Solar Power?
Concentrated Solar Power (CSP) uses mirrors called heliostats or parabolic mirrors to focus sunlight onto a central receiver. The concentrated heat raises the temperature of molten salt or another heat-transfer fluid, which is later used to produce steam that drives electricity-generating turbines.
How Molten Salt Storage Works
- Thousands of mirrors track the sun throughout the day.
- Sunlight is concentrated onto a receiver tower.
- Molten salt is heated to very high temperatures.
- The heated salt is stored in insulated tanks.
- Stored thermal energy is used to generate steam.
- Steam drives turbines to produce electricity day and night.
Why Morocco Is Investing in CSP
- Reliable electricity after sunset.
- Reduced fossil fuel dependence.
- Lower greenhouse gas emissions.
- Improved national energy security.
- Better integration of renewable energy into the grid.
- Supports long-term climate and sustainability goals.

|---|---|---|
| Electricity at Night | ✔ Yes (with thermal storage) | ✖ No (without batteries) |
| Energy Storage | Molten Salt | Battery Systems |
| Best Use | Utility-scale power plants | Residential & Commercial Rooftops |
Frequently Asked Questions
What is Concentrated Solar Power?
Concentrated Solar Power uses mirrors to focus sunlight and produce high-temperature heat that generates electricity.
How does CSP generate electricity after sunset?
Heat is stored in molten salt during the day and later used to generate steam for electricity production after sunset.
What is molten salt energy storage?
Molten salt stores thermal energy at very high temperatures, allowing power plants to generate electricity long after sunlight disappears.
Is CSP better than solar PV?
CSP is particularly valuable for large utility-scale power generation because it offers integrated thermal energy storage, while solar PV is more common for residential and commercial installations.
Why is Morocco investing in CSP?
Morocco is expanding CSP to improve energy security, reduce emissions, and provide dependable renewable electricity.
Which countries use Concentrated Solar Power?
Morocco, Spain, the United States, China, the United Arab Emirates, Chile, and South Africa have invested in CSP projects.
