Ameren Missouri to Acquire 400-MW Wind Farm

LCG, May 23, 2018--Ameren Missouri, a subsidiary of Ameren Corporation, Monday announced that it has entered into an agreement to acquire, after construction, a 400-MW wind farm in northeast Missouri. The project will include 175 wind turbines to be installed by an affiliate of Terra-Gen, LLC. Construction is expected to commence in summer 2019.

Impacts of High Variable Renewable Energy Futures on Wholesale Electricity Prices, and on Electric-Sector Decision Making

May 23, 2018 -- Lawrence Berkeley Lab partnered with LCG Consulting to develop a large number of variable renewable energy (VRE) scenarios to derive future generator portfolios and hourly price and emissions series. The main objective of this exercise is to offer policymakers, utilities and grid authorities a long-range view of how current choices could impact their future ability to cope with changes in the electric sector.

ERCOT Forecasts Record-breaking Summer Peak Demand

LCG, May 2, 2018--The Electric Reliability Council of Texas (ERCOT) Monday released its final Seasonal Assessment of Resource Adequacy (SARA) report for this summer season (June - September). ERCOT, the grid operator for most of Texas, continues to predict record-breaking peak usage this summer season.

The report includes a 72,756 MW summer peak load forecast based on expectations for normal weather, and remains unchanged from the forecast used for the preliminary summer SARA report issued March 1. The Texas economy continues to drive demand, and the anticipated peak demand is expected to be over 1,600 MW higher than the all-time peak demand record of 71,110 MW set in August 2016.

The forecast peak demand, combined with recent plant retirements and delays in some planned resources, is expected to result in tight reserves that could trigger the need for ERCOT to deploy such resources as Ancillary Services and contracted Emergency Response Service capacity to maintain sufficient operating reserve levels. ERCOT may also request that Transmission and/or Distribution Service Providers (TDSPs) implement load control measures established through Standard Offer contracts with their customers. There is approximately 2,300 MW of such additional capacity available to ERCOT for addressing reserve deficiency situations.

Total generation resource capacity for the summer season is now estimated at 78,184 MW, which is up by 525 MW relative to the amount reported in the preliminary summer SARA report. The increase is due primarily to the change in status of a mothballed unit (300 MW) from unavailable to available for the summer season, a planned gas-fired resource (226 MW) that is now expected to be available in mid-June, and a formerly unavailable Switchable Generation Resource (54.6 MW) that is planned to be available to the ERCOT grid. The change in total capacity also reflects some minor decreases such as a smaller Private Use Network capacity contribution and the postponement of the projected in-service date for a small planned gas-fired unit to the fall of 2018. The total amount of planned additions for the summer now stands at 728 MW, constituting 345 MW of thermal sources and 383 MW of renewables based on the expected summer peak capacity contributions.

The final summer unit outage forecast of 4,349 MW remains unchanged from the preliminary summer SARA report. ERCOT developed this forecast from outage data for the last three summer seasons.
