Duke Energy Sustainable Solutions Announces 207-MW Ledyard Windpower Project in Iowa

LCG, September 23, 2021--Duke Energy Sustainable Solutions, a nonregulated commercial brand of Duke Energy, earlier this week announced the construction of the 207-MW Ledyard Windpower project in Kossuth County, Iowa. Verizon Communications entered into a 15-year virtual power purchase agreement (VPPA) for 180 MW of the wind energy for 15 years to meet its net-zero goals.

Illinois Governor Signs Energy Bill to Transform the Electric Sector

LCG, September 16, 2021--The Governor of Illinois yesterday signed into law SB 2408, a wide-ranging bill that will significantly impact the electric sector, along with impacts on the transportation sector, jobs and communities. The legislation requires 100 percent carbon free energy by 2045 and targets a path to achieve 100 percent renewables by 2050.

Summer 2021 Resource Adequacy Scenarios- Revised Report

LCG June 11, 2021--LCG Consulting (LCG) has released its analysis of resource adequacy in ERCOT for summer 2021, as we do each spring.

Under expected conditions, in agreement with ERCOT’s expectations, our model shows the ERCOT region will have enough installed generating capacity to serve peak loading condition. ERCOT projects peak load as 77,144 MW with a total resource capacity of 86,862 MW.

However, more challenging conditions are always possible. This summer follows what may have been the most extreme weather event to ever test the modern Texas grid, February’s storm that is described as a 1-in-a-100 event. The state is still reeling from its effects, and electricity market participants are facing much stronger public scrutiny of reliability, as well as new legislation, some still pending resolution.

Resource adequacy analysis for the region is critical during extreme summer loading conditions. Reserves have tightened because of recent retirements. The ERCOT landscape is rapidly evolving, with significant transmission changes and unprecedented growth of renewables, particularly wind.

Beside using the conditions that ERCOT itself expects to model this upcoming summer, LCG chose three other scenarios to model: reduced wind output, increased generator outages, and higher-than-expected load.

Each scenario sheds light on where issues might arise and what magnitude of effects might occur.
