The phrase "as a base load" is correct and usable in written English.
It is typically used in discussions about energy production, referring to a consistent level of demand that must be met by power generation.
Example: "The power plant operates primarily as a base load, ensuring that the grid remains stable during peak usage times."
Alternatives: "as a steady load" or "as a fundamental load".
"Unlike solar or wind energy that can vary in output due to weather conditions, geothermal energy is pretty consistent and stable in output and has the potential to serve as a base load for energy production," said Keiichi Sakaguchi, head of the geothermal resources research group at the National Institute of Advanced Industrial Science and Technology.
The overall challenge is to design a robust plant that has a sufficiently low total cost of electricity so that it is interesting to build, but it must also have a sufficiently low variable cost of electricity so that it will be put in operation as a base load plant once it is built.
The importance of the fossil energy is that it can serve as a base load.
Different from photovoltaic and wind power, it can serve as a base load for the power grid.
The nuclear generation does not depend upon such an uncontrollable condition (e.g., weather), so being able to serve as a base load.
For heating purposes within the farm and partly as a base load for local heating networks within the surrounding region as well, the farms are able to reach a level of heat usage well above the national average.
Adding a storage system increases the solar share of the power plant by as much as 47% for a base load thermal power output of 1 MW.
The steady, reliable supply of energy constitutes a significant advantage over solar and wind power as it provides a base load of energy.
(d Control systems that are normally in operation, such as required by a base load system, must be inspected and tested once each calendar year but with intervals not exceeding 15 months.
In industry, energy must usually be available as a base-load commodity.
Natural gas will be used as a base-load fuel as well as to back-up solar power when the sun is not shining.
