Amazon.com Inc (NASDAQ:AMZN) has committed to buying electricity from 450 MW of solar parks to power its data centers in California under a deal with power distributor AES Corp (NYSE:AES).

The US e-commerce giant has sealed two power purchase agreements (PPAs) that will see it get renewable energy in the California Independent System Operator (CAISO) market. The power will be sourced from solar photovoltaic (PV) plants and 225 MW of battery storage projects with a four-hour duration.

The off-take deals were announced by AES on Thursday.

Concentrated solar-thermal power harnesses the sun's energy without photovoltaic panels, using mirrors to concentrate the sun's rays.

When you think of solar energy, you probably picture the photovoltaic panels that capture sunlight to be converted to electricity. But there are other ways to harness the sun’s power. One method attracting growing interest is called concentrated solar-thermal power, or CSP, which uses mirrors to reflect and concentrate the sun’s energy.

CSP has been held back by technical challenges and a shortage of funding and government incentives compared with other sources of renewable energy. But as the sense of urgency about replacing fossil fuels continues to grow, spurring demand for carbon-free energy, a number of increasingly well-funded entities are trying to improve the technology. Proponents say the heat that CSP systems produce and their storage capacity offer advantages over other renewables for generating grid-scale electricity and fueling various industrial processes.
