I like that Opus one provides tools to help optimize our power flow plans. The interface is not always intuitive. There are a lot of options so you can be lost in data before you know it! When you get used to how the software works, it helps with our optimization needs. It also helps us manage and report on reliability as well as transmission losses. Our electrical team looks at their plan once a month and knows where they are going wrong. By using this software we make sure we have all of the information we need to fix any problems or errors.
