Couple statements about reliability and cost
Author: Northern Indiana Public Service Company
Indiana Utility Regulatory Commission: Cause 45159 [link] – Verified Direct Testimony of Andrew S. Campbell, Director of Regulatory Support & Planning, Northern Indiana Public Service Company (NIPSCO) [link] Q18. How will reliability be maintained when the wind isn’t blowing? A18. NIPSCO will continue to dispatch its steam and gas fleet and other available wind generation, as well as purchase power from MISO, to meet customer demand and reliability needs throughout the term of the Roaming Bison Wind Energy PPA. This . . .

Author: Greenstone, Michael; McDowell, Richard; and Nath, Ishan
[Abstract] Renewable Portfolio Standards (RPS) are the largest and perhaps most popular climate policy in the US, having been enacted by 29 states and the District of Columbia. Using the most comprehensive panel data set ever compiled on program characteristics and key outcomes, we compare states that did and did not adopt RPS policies, exploiting the substantial differences in timing of adoption. The estimates indicate that 7 years after passage of an RPS program, the required renewable share of generation . . .

Author: Linneman, Thomas; and Vallana, Guido
In Germany the installed nominal capacity of all wind turbines has increased eightfold over the last 16 years to 50,000 megawatts today. In the 18 most important European countries using wind energy today, the nominal capacity rose by twelve times to more than 150,000 megawatts. One essential physical property of wind energy is its large spatiotemporal variation due to wind speed fluctuations. From a meteorological point of view, the electrical power output of wind turbines is determined by weather conditions . . .

Author: Thind, Maninder; et al.
Abstract. Environmental consequences of electricity generation are often determined using average emission factors. However, as different interventions are incrementally pursued in electricity systems, the resulting marginal change in emissions may differ from what one would predict based on system-average conditions. Here, we estimate average emission factors and marginal emission factors for CO₂, SO₂, and NOx from fossil and nonfossil generators in the Midcontinent Independent System Operator (MISO) region during years 2007–2016. We analyze multiple spatial scales (all MISO; each of . . .
