Welcome to Integrating-Renewables.org
We have launched this site to coincide with the publication of the report Integrating Renewables into the Generation Mix: Challenges and Unknowns.
> Wind Potential
Most of the material in this special report by the editors of Las Vegas-based PSI Media Inc, content developers for print and electronic publications focusing on energy technologies and markets, came from presentations and discussions at “Integrating Renewables Into the Generation Mix: Challenges and Unknowns,” a one-day workshop, September 13, developed by CTOTF in cooperation with NV Energy.
The goal of the meeting, presented and managed by Wickey Elmo, president, Goose Creek Systems Inc, Indian Trail, NC, respected in the electric power industry for forward-looking technical conferences and companion exhibitions, was to explore how state-mandated Renewable Portfolio Standards (RPS) may impact operation of the nation’s electric power system. Experience to date indicates that wind—the preferred renewable resource based on installed capacity and planned additions—often does not blow when power is needed most. In fact, wind generation maybe at its peak in the evening, when demand is lowest.
To meet the RPS, utilities without bulk energy-storage assets must send out renewable power as it is produced. At night or during the shoulder months, kilowatt-hours from renewables can be as much as 50% of the total energy supplied—possibly more. Mother Nature may be somewhat predictable, but not entirely so. This dictates the need for back-up generation resources, energy from neighbors via the grid, load shedding, and/or other immediate solutions to compensate for the shortfalls in energy production from intermittent renewables. Where fast-start/rapid-ramp assets are optimal for backing up renewables, or at least part of the solution, gas turbines are the likely generation option and the reason CTOTF hosted the workshop.
The report begins with an executive summary that captures the meeting’s highlights. It is followed by in-depth coverage of 14 selected presentations discussing the challenges renewables present to grid operators and the wear and tear wind and solar assets can cause conventional generating units. A couple of presentations profiled discuss the promise of the smart grid and demand-side management (DSM) solutions for mitigating renewables impacts; two case studies illustrate real-world experience.
Finally, this report’s companion website at www.integrating-renewables.org, scheduled to go live December 1, is designed to enable the free flow of information and ideas, share experiences, identify best practices, etc, to facilitate the transition to an electricity supply system with a large renewables component. Discussion forums include grid operations, smart grid/DSM, O&M impacts on conventional generation, and energy storage. Sign up today and join the dialogue.
