Lake Elsinore Advanced Pump Storage (LEAPS) Benefit to Cost Analysis

In support of Affidavit of Ziad Alaywan on behalf of the Nevada Hydro Company, performed with ZG team an economic benefit analysis to calculate the net benefit of the LEAPS project for two sample years, 2026 and 2030, utilizing the CAISO’s TEAM approach and PLEXOS software. The economic benefit analysis for the LEAPS project included determination of the consumer economic benefits of the LEAPS pump storage project based on an assessment of 2026 and 2030 study years for multiple economic benefit categories including:

• Energy cost savings to consumers,

• Load following capability benefits,

• Reduced renewable energy curtailments due to overgeneration, and

• Reduced overbuild of RPS capacity to meet 50% objectives.

 

The assessment considered California’s policy objectives of 50% RPS by 2030 as well as lower Greenhouse Gas emissions targets. The ZG team provided technical expertise and support to LEAPS project development and legal team. This included discussion with CAISO staff regarding analysis they have performed or are currently performing. Provided project coordination and technical support of related submissions to ISO’s TP process.

Valuation Assessment for the Enhanced Gas Turbine (EGT) System

Wellhead Power Solutions LLC retained ZGlobal to perform an independent assessment and quantification of the potential economic benefits of its proposed Enhanced Gas Turbine (EGTTM) System. The objective of ZGlobal’s assessment was to quantify potential economic benefits provided by the EGTTM system:

1. Energy cost savings,

2. Ancillary Services cost savings with primary focus on benefit from spin and regulation, and

3. Emissions reduction impact.

 

Economic benefits were quantified by running 8760-hour production cost simulations for a near term study year to determine the least cost dispatch for the California grid.

Developed independent Regulation and Mileage Price Forecasts for ARES Corporation

Utilizing historical prices, forward curves, expectations of changes to the energy sector and grid, and production cost modeling simulations under various market scenarios, developed price forecasts for three periods, short-term (1-2 years), mid-term (3-5 years), and long-term (beyond 5-years). Prepared observations and summary to Client regarding the drivers of prices in an Executive presentation, and also provided price forecast data in MS Excel and PowerPoint slide deck describing results.

Assessment of Drivers of Potential for Curtailment for Solar Projects

ZGlobal provided a technical assessment utilizing results from 8760-production cost modeling to determine driving factors that have significant impact to prices at Pnodes associated with multiple solar projects, the likelihood of realizing those drivers over the term of the PPA and resultant risk of curtailment.

Christine and her team have performed settlements with CAISO and other bilateral counterparties for the resources under ZG management for over $2 Billion since 2012.  The graph below shows the annual volume of settled transactions:
