Curtailment Mitigation Strategies

Curtailment Mitigation Strategies

Curtailments and energy imbalances can be costly for any generator, whether you are a new market entrant, such as solar PV, or an industry veteran, such as hydro. Generators used to be able to set it and forget it when it comes to scheduling and operations. There may have been a rare occurrence when the CAISO instructed your generator to curtail through an exceptional dispatch. And the occasional forced outage was inevitable, but nothing to fret over. However, more recently, generators are experiencing frequent instances of curtailment, and greater imbalance uncertainty due to the more intermittent profile of the generation fleet and higher market price volatility.

GridSME Works to Enhance the Energy Storage Movement

GridSME is excited to work with many of the industry’s leading developers in the emerging energy storage space. Our team collaborates with clients on detailed analyses of standalone storage installations and combined “generation + storage” projects.

From a feasibility analysis perspective, GridSME evaluates the technical characteristics of an existing generation facility or proposed new facility to determine the optimal configuration and operation of integrating an energy storage resource. Additionally, GridSME evaluates the economic considerations and constraints associated with the facility, such as the PPA terms, interconnection requirements, and go-to-market considerations. We emphasize the need for developers to be cognizant of the technical and economic aspects of integrating energy storage with existing or new generation facilities (e.g., Solar/Wind + Storage).

Eric Whitley Speaks at Solar O&M: North America


This morning, Eric Whitley is speaking at the Solar O&M: North America conference in San Francisco. His two sessions are “Curtailment for PV Plants” and a panel on “Grid Integration Issues,” specifically addressing the following:

  • Criteria and situations where curtailment is obliged
  • How do utilities create a market environment that is more conducive to economic renewables curtailment
  • When day-time economic curtailment of solar resources becomes an issue
  • Future outlook: how will curtailment (regulation) change and what will be the impact of this
  • Power, voltage, and frequency regulation
  • Outage scheduling and downtime minimization
  • NERC compliance rules that apply
  • What can be learned from pilot projects on PV integration and large-scale storage

Wind and Solar Installations Soar as Production Tax Credit Winds Down

Wind and Solar Installations Soar as Production Tax Credit Winds Down



It has been another banner year for the wind and solar industries. Wind capacity additions for 2012 will hit a record high (near 12 GW) as total installed capacity hit 50 GW in August. Additionally, the Solar Energy Industries Association forecasts that 3.2 GW of solar will be installed in 2012.  All of these additions, however, may be the grand finale of a spectacular 10 year run for the renewable power industry.

This is due to the expiration at year’s end of the Production Tax Credit (PTC). According to a recent article in AOL Energy, the last three times the PTC has expired installation rates plunged 94%.

Leaving the politics of whether or not the PTC should or should not be renewed, we can all agree that a significant amount of renewables will be coming online in the next few months. Even with the end of the PTC states with renewable 29 states, Washington D.C., and two U.S. territories renewable portfolio standards (RPS) and another eight states and two territories have renewable goals. This means there will still be lots of renewables coming down the pike.

This large increase in variable generation continues to present challenges to system operators especially during windy nights when load is low. Operators must be prepared to meet their schedules and remain in balance 24/7/365.

Is your organization ready to integrate more variable generation? GridSME’s experts are experienced in system integration and optimization. Give us a call – maybe we can help.
