NEMS and the Duck Issue

Posted by OnLocation on May 25, 2016 11:23:20 AM

As part of our ongoing support for EIA and other government agencies, OnLocation has been studying the potential impact of large amounts of solar generation on grid stability as it relates to the National Energy Modeling System (NEMS).  The issues stem from the timing of solar generation during the day, particularly in months when electricity demand is relatively low such as early spring before air conditioning is needed.  The potential impact on the grid from the high solar generation on days with low electricity demand and the steep reduction in solar in the evening has been dubbed the “duck” issue by the California ISO and was described in a recent post by the Energy Institute at Haas (

Our Complex Electric System

Posted by OnLocation on Mar 17, 2016 11:00:00 AM

A recent article posted on The Energy Collective titled “The U.S. Electricity System in 15 Maps” uses a series of maps to illustrate the diversity and complexity of the U.S. electric system as a foundation for understanding some of the conditions impacting the power industry. The maps highlight the regional variety that exists in the current generation mix, electricity prices, and the energy resources available, including wind, solar, natural gas and coal. Region-specific regulations such as renewable portfolio standards (RPS), the Regional Greenhouse Gas Initiative (RGGI) and others add to the complexity of these markets and the difficulty of projecting how these markets will change in the next 10-20 years.

For example, the client might be a non-governmental organization aiming to release a report at the beginning of a new administration or a session of Congressional activity.

How Much Does It Cost to Run the NEMS Model?

Posted by OnLocation on Aug 28, 2015 11:35:00 AM

Many of our clients - especially in government or non-profit organizations - work within a tight budget. It’s understandable, then, that cost is one of their biggest concerns as they seek to have their questions answered.
