Yet there is a less visible factor that directly impacts consumption, plant reliability, and operating costs: <a href=\"https:\/\/energia-europa.com\/en\/power-quality\/\">power quality<\/a>.<\/p>\n<p>Power quality is not about how much electricity you consume, but <em>how<\/em> electricity reaches your plant and <em>how<\/em> it is used.
