UPSToday. - This is one of information to you about the solar power with the article titled with Environmental official helps spread solar power in Commentary: Rocky Mountain Power isn’t accurately calculating for wind and solar power 6 that written By Michael Budig.
Every two years, PacifiCorp (doing business as Rocky Mountain Power) is required to file an Integrated Resource Plan (IRP) outlining its strategy to supply and manage electricity for the next 20 years across six states that include Utah. The IRP is defined as a process to consider all known resources on a consistent and comparable basis “in order to meet current and future customer electric needs at the lowest cost to the utility and its customers.”
This year, PacifiCorp failed to meet that criterion.
Utah’s Division of Public Utilities reviewed the IRP and found that PacifiCorp has failed to conduct a proper analysis of generating capacity and energy demand. The mandated economic analysis failed to include a cost/benefit comparison of wind and solar projects with existing coal plants. Pacificorp also assumed unrealistically high costs for solar power and battery storage. In future, PacifiCorp needs to update its modeling assumptions for solar and wind power and battery storage.
The IRP also hides important information from regulators and consumers. The Sierra Club, assisted by Synapse Energy Economics, reviewed the IRP and found its coal unit valuations grossly lack transparency when compared to plans from other coal-dependent states such as Idaho and New Mexico. As a result, it is difficult to accurately evaluate ongoing costs of the value, risks and tradeoffs of existing coal plants as compared to possible clean energy substitutes.
In the 2011 IRP, PacifiCorp acknowledged that low natural gas prices could make coal power uneconomic. That forecast has come true. Today, natural gas prices are even lower than envisioned, resulting in the closure of many coal-powered plants throughout the U.S.
