According to the 2022 Solar Generation Index, Underperformance is an Ongoing Issue for U.S. Solar Energy Projects Larger Than 1 MW

SAN FRANCISCO – February 9, 2023 (Updated July 31, 2023) – Based on the most comprehensive data set on the performance of U.S. solar energy assets, ForeFront Power’s U.S. solar energy asset management portfolio is performing 7% above the nationwide industry average. ForeFront Power’s Asset Management subsidiary helps commercial and industrial solar producers carefully balance costs with production, maximizing both energy output and financial results.

The 2022 Solar Generation Index reports that in 2021, U.S. solar energy projects larger than 1 MW performed at 92% to Weather Adjusted (WA) P50, which is the weather-adjusted probability that a solar asset is at least 50% likely to achieve the minimum estimate for its performance. Meanwhile the U.S.-based solar assets managed by ForeFront Power ranging in size from 60 kW to 5 MW performed at 99% WA P50 within the past 12 months.

Produced by kWh Analytics, the 2022 Solar Generation Index assesses 10 years of operational data from 500 U.S. solar energy projects larger than 1 MW. According to the report, the performance of these assets ranges from 5-10% below their initial WA P50 estimates. The report indicates that underperformance is an ongoing issue that affects solar projects regardless of capacity, region and mount type.

“The Solar Generation Index is a reminder that comprehensive energy asset management is integral to the clean energy future,” said Yumi Furukawa, interim CEO of ForeFront Power. “With the strong performance of ForeFront Power’s operating portfolio, we are pleased to also provide comprehensive diagnostic, monitoring and operational expertise on third party-owned projects, balancing both project yields and financial savings as we would for our own assets.”

Beyond optimizing system performance and attending to routine operations and maintenance issues, ForeFront Power helps project owners and investors track and leverage public incentives, conduct ongoing energy consumption assessments and participate in sustainability reporting.

Case Study: Los Altos School District, California


Los Altos School District (LASD) is a top-rated school district in California, operating seven elementary and two junior high schools. As part of the district’s broader efforts to go zero net energy, LASD tapped ForeFront Power, a leading North American developer of solar and energy storage solutions, to develop a 1.4 MW solar energy portfolio comprising nine projects across LASD school campuses.

A third-party vendor was responsible for managing the District’s solar energy portfolio in its first year of operation. Recognizing inefficiencies in system performance, ForeFront Power took the asset management in-house in 2020, delivering remote diagnostics, monitoring and financial reporting.

By the end of 2021, LASD and ForeFront Power were able to drastically decrease the solar portfolio’s maintenance events (known as “truck rolls”) compared to the period of time under the previous vendor’s management. All project sites receive annual inspections involving checking and tuning all equipment, resulting in only two production-impacting maintenance events in 2021 – a reduction of 90% in just 2 years. To date, the portfolio has achieved an average performance ratio of 103.9% of the contracted production guarantee (101% of the WA P50), in large part due to updated panel cleaning procedures resulting in cleaner panels than originally modeled.

Benefiting from ForeFront Power’s ongoing asset management, the 1.4 MW solar portfolio has already helped LASD save nearly $1.4 million in 4 years and is expected to save nearly $3 million in 10 years of operation.

“The cost savings are crucial and a great benefit for our students and teachers,” said Randy Kenyon, LASD Chief Business Official.

In addition to the financial benefits, the solar portfolio is helping LASD avoid the emission of 1,754 tons of CO2 annually. This is equivalent to avoiding the annual CO2 output of 336 cars on local roads, which is a net positive for the region’s air quality. By significantly reducing District energy costs, the solar portfolio is also redirecting school funds to classrooms, teachers and educational programs for students.

LASD’s solar project was named a 2022 “Project of Year” by Environment + Energy Leader.

Including the LASD portfolio, ForeFront Power’s California-based solar assets ranging in size from 60 kW to 2 MW performed at 99% WA P50 in 2022.

Case Study: City of Ames, Iowa

In response to overwhelming community feedback, the City of Ames set out to develop SunSmart Ames, the City’s first community solar project. This project allows any municipal electric customer unable to install solar panels on their own property to opt for locally generated solar energy by purchasing shares of the facility’s production, called “Power Packs.”

Ames City Council selected ForeFront Power to develop and operate the community solar project. Despite the challenges of COVID-19, SunSmart Ames was constructed and completed in 2020, representing 2 MW of solar energy dedicated to the local Ames community, including the Iowa State University campus. Each Power Pack represents 175 W of generating capacity and entitles customers to a monthly bill credit for 20 years, through a one-time investment of $300. Ames Electric customers who bought Power Packs received their first utility bill credits in February 2021.

ForeFront Power’s Asset Management team has since helped the City of Ames maintain its community solar project at a lifetime performance ratio of 108% of the contracted guarantee (and 95% of the WA P50). Over the next 20 years, the SunSmart community solar program is expected to produce enough electricity to power 440 Ames homes each year, offset 113 million gas-powered car miles, and reduce the city’s CO2 emissions by about 57,000 tons.

The City of Ames’ community solar project was named a 2021 “Project of Year” by Environment + Energy Leader.
