FirstEnergy Corp. wants to deactivate the Pleasants Power Station, a 1.3-GW coal power plant near Belmont, West Virginia, by January 2019. The plant began operations in 1979. During construction of the plant, cooling tower #2 collapsed, killing 51 workers. The construction accident in April 1978 is still considered one of the worst in U.S. history. Courtesy: FirstEnergy

Swift (and Angry) Reaction to Trump Move to Save Coal, Nuclear Plants

Reactions from U.S. energy and legal and regulatory groups began pouring in minutes after the White House confirmed on June 1 that President Trump has directed the Department of Energy (DOE) to act immediately to stop the loss of uneconomic coal and nuclear plants.  White House Press Secretary Sarah Sanders said in a June 1 […]

Renewable Growth Soars, Buoyed by Distributed Generation

Nameplate renewable capacity surged to more than 2,000 GW worldwide at the end of 2016, constituting more than 28% of total generating capacity (Figure 6). Most (56%) was hydropower, followed by wind (23%), and then solar, mostly from photovoltaic (PV) at about 15%. According to the International Renewable Energy Agency (IRENA) the expansion was fueled […]

Case Study: Monitoring Health and Performance of Grid-Scale Battery Installations

UniEnergy’s Technologies (UET) manufactures and installs large-scale energy storage solutions for utility, commercial, and microgrid applications. Their battery systems enable customers to address power needs, such as “frequency regulation” as well as “transmission generation deferral” and “peak shaving. This case study details how OSIsoft’s Connected Services enabled UET to offer capacity guarantees for their technology.
