Energy Resilience: Supporting Grid Resilience and our Communities

In July 2024, Generac began the second phase of the energy resiliency project awarded in 2023 known as Programa Accesso Solar (Solar Access Program), funded through the Puerto Rico Energy Resilience Fund (ERF).

This initiative brings clean, grid-resilient energy storage to low-income communities prone to frequent and prolonged power outages, as well as to homes with residents reliant on energy for medical needs.

Powering Resilience in Puerto Rico

Our Massachusetts initiative leverages federal funding to bolster grid resilience through advanced energy solutions.

The project involves installing energy technologies such as Wi-Fi thermostats, batteries and optimized electric heat pumps in disadvantaged communities across the Commonwealth.

These systems not only improve reliability for residents but also demonstrate Generac's ability to integrate energy technologies into cohesive solutions. The initiative provides resiliency and incentives for low-to middle-income residents and creates a model for sustainable energy transitions for the broader grid in other regions.

Enhancing Grid Stability in Massachusetts

Generac was awarded new federal funding in 2024 to support California's water utilities and Disadvantaged Communities (DACs) through advanced microgrid technology.

These microgrids, managed by Distributed Energy Resource Management systems (DERMs) will be capable of delivering reliable load

reductions during periods of grid stress.

Beyond reducing strain on the electric grid, this project is expected to improve air and water quality, enhance reliability and create operational cost savings.

for our customers. We believe that improving energy sustainability includes three key elements: decarbonization; digitalization, and decentralization. In order to proactively address energy resiliency within our business, we engage our leaders annually through the strategic planning process to identify sustainability risks and opportunities that may affect business groups and strategic initiatives in the short (0-3 year), medium (3 to 10 year), and long-term (10 - 25 year).

We recognize that addressing climate change isn't merely an environmental responsibility - it's also essential for our long-term business success. That's why Generac includes climate-related risks and opportunities in our strategic planning and risk management processes.

Risk Management

Generac manages its climate-related risks and opportunities through our annual enterprise risk assessment process, business continuity plans and annual strategic planning process.

To aid in this effort, we're pleased to include a summary of climate-related reporting in accordance with the recommendations of the Task Force on Climate-Related Financial Disclosure (TCFD).

For details, please refer to the appendix.

Metrics & Targets

In 2022, Generac launched a greenhouse gas inventory plan, prioritizing Scope 1 and 2 emissions calculations in alignment with the Greenhouse Gas Protocol Corporate Standard.

RISKS

OPPORTUNITIES

Generac's product mix promotes resource efficiency and lower-carbon options for our customers and communities while improving overall grid resiliency.

Providing Climate Resiliency to Our Customers

As a leading provider of home standby power in the US, Generac helps customers manage power outages after significant climate events.

Before a storm strikes, we alert customers of potential weather impacts. After the storm, we take our expertise on the road, deploying our Storm Response Team to the areas impacted by the disaster.

Outage Preparedness

Generac offers free guides to empower our customers in preparing for hurricane season, high winds, tornadoes and thunderstorms.

Plus, our free Power Outage Central link consolidates utility outage data from across the nation into a user-friendly interface. This tool enables users to easily visualize the impact of power outages at both local and statewide levels in near real-time.

Storm Response Dispatch

Our Storm Response Team consists of trained Generac employee volunteers who travel to areas affected by a disaster to help residents and communities restore access to power as quickly as possible.

In 2024,

there were:

27 confirmed weather/ climate disaster events

5 major hurricanes made landfall in 2024...

...with losses exceeding

$1 billion each

The Storm Team was dispatched three times in 2024 for Hurricanes Beryl, Helene and Milton, providing support to over 350 families and small businesses.

"

We will continue seeing increased severe weather activity result in power outages - which pose immense risk to safety and security. Backup power is the cornerstone of a well thought out preparedness plan."
