Evaluating the Capabilities of Behind-the-Meter Solar+Storage for Providing Backup Power during Long-Duration Power Interruptions

<<REGISTER HERE>>

Customer-sited solar+storage can help homes and businesses maintain essential activities during grid outages. A new report by Berkeley Lab estimates the performance of commercially available solar+storage systems in providing behind-the-meter critical-load or whole-building backup power during long-duration outages. Researchers modeled scenarios across a wide range of geographies, building types, and power interruption conditions. The study also considers a set of 10 historical long-duration power outage events and evaluates how solar+storage could have performed in providing backup power during those specific events. In this webinar, hosted by Clean Energy Group, report co-author Galen Barbose will present the findings.

State Leadership in Solar+Storage, Featuring Maryland and Oregon

<<REGISTER HERE>>

Solar+storage programs provide a multitude of customer benefits, from cost savings to energy resilience. This webinar will highlight two well-designed and impactful programs that are supporting the development of solar+storage projects in their state.

The Maryland Energy Administration’s Resilient Maryland / Resiliency Hubs Grant Program are helping local organizations develop resilient energy system projects that bolster their operations, protect communities, enhance sustainability, and achieve energy affordability. Resilient Maryland provides funds to local organizations to help pay for feasibility analyses, preliminary modeling, and other important preconstruction activities in the development of microgrids, resilient facility power systems, and resiliency hubs for Maryland communities, businesses, and critical infrastructure. The Resiliency Hub Program provides capital funds for the installation of solar PV and battery storage systems that enable them to become “resiliency hubs,” which are sited in local, community-serving locations where residents can access electricity during grid outages to power their essential electrical devices, to refrigerate temperature-sensitive items, and to shelter in safety.

The Oregon Department of Energy’s Solar+Storage Rebate Program offers rebates to residential customers and low-income service providers that install solar or solar paired with battery storage systems. At least 25 percent of rebate funds each year are reserved for low- or moderate-income residential customers and low-income service providers, with higher rebate amounts available to these groups. ODOE collaborated with Oregon Housing and Community Services, the solar industry, and other energy partners to develop a streamlined, stackable, and cost-effective process to determine income eligibility for program participants and maximize incentives for project cost savings. The 352 completed projects that received a rebate in the first round of funding represent solar electric generation that is estimated to displace 2,193 metric tons of carbon dioxide equivalent per year.

In this webinar, representatives from the Maryland Energy Administration and the Oregon Department of Energy will present their programs and answer questions from the audience. CESA’s Todd Olinsky-Paul will moderate.

Innovative Avenues to Public Participation in Clean Energy Development, Featuring Connecticut and Washington

<<REGISTER HERE>>

This webinar will highlight two impressive and impactful state programs that are accelerating the development of clean energy while increasing public participation in the process.

The Connecticut Green Bank’s Green Liberty Bonds program, which is modelled after the war bonds of the 1940s, allows individual investors to purchase bonds in low-dollar denominations, enabling people to directly participate in the green economy and earn a return on their investment. The proceeds of Green Liberty Bonds are invested in projects that confront climate change in Connecticut. The first issuance of the Green Liberty Bonds in July 2020 sold nearly $17 million, and the second issuance in May 2021 sold nearly $25 million.

In Washington, the 2021 State Energy Strategy provides a roadmap for the state to meet its critical and ambitious energy and climate goals: transitioning to 100% clean electricity by 2045 and reducing greenhouse gas emissions. The strategy puts equity and climate justice upfront because climate change will inflict greatest harm on overburdened communities and low-income households. This work was guided by a 27-member advisory committee representing a broad set of governmental, Tribal, environmental, consumer, and industry interests. The advisory committee meetings were professionally facilitated to ensure meaningful and equitable engagement. The state also actively engaged political leaders and offered multiple opportunities for public input and review.

In this webinar, representatives from the CT Green Bank and the Washington Department of Commerce will present their programs and answer questions from the audience. CESA’s Vero Bourg-Meyer will moderate.

State Leadership in Decarbonizing the Building Sector, Featuring California and New York

<<REGISTER HERE>>

The building sector is a substantial contributor to greenhouse gas emissions. This webinar will highlight two state initiatives that are making a big impact in decarbonizing this sector.

The California Energy Commission’s 2022 Building Energy Efficiency Standards for newly constructed buildings and renovated buildings blazes a trail for states seeking to decarbonize aggressively and cost-effectively. This update to the state energy code includes electric heat pumps as the performance standard baseline for single-family homes, multifamily homes, and select commercial buildings. It also includes a first-in-the-nation standard for solar-electric systems plus battery storage for select nonresidential building types, including high-rise multifamily, hotel/motels, medical clinics, retail stores, restaurants, and schools. Over the next 30 years, this code is estimated to provide the state with $1.5 billion in environmental benefits, equivalent to taking nearly 2.2 million cars off the road for a year.

The New York Clean Energy Initiative, a joint effort of the New York State Energy Research and Development Authority (NYSERDA) and New York State Homes and Community Renewal (HCR), provides incentives and technical assistance for electrification and high-performance envelope improvements in new and existing multifamily affordable housing developments. The program offers a replicable and scalable model to accelerate decarbonization of affordable housing, a notoriously hard-to-reach sector. Through this program, more New York families will benefit from healthy, clean energy homes, and housing developers have streamlined access to technical assistance and clean energy incentives to support decarbonization.

In this webinar, representatives from the California Energy Commission and NYSERDA will present their programs and answer questions from the audience. CESA’s Warren Leon will moderate.

Introduction to Floating Wind Technology and Markets

<<REGISTER HERE>>

Offshore wind is a rapidly accelerating industry in the United States, but many challenges lie ahead. Some coastal waters, including those off the West Coast of the US, are too deep to install traditional, fixed-bottom wind turbines. Around the world, renewable energy developers are turning to floating turbines as a solution. This promising technology will revolutionize where and how we generate offshore wind power, but states and developers must work together to determine how best to deploy it.

In this webinar, hosted by the from Clean Energy States Alliance (CESA) and World Forum Offshore Wind (WFO), Adrienne Downey with offshore wind project developer Hexicon Group will present the current state of floating offshore wind technology around the world and will chat with California Energy Commissioner Kourtney Vaccaro about the potential of floating offshore wind in the US and the obstacles to its adoption.

Behind-the-Meter Energy Storage: Comparing State Policies

<<REGISTER HERE>>

A variety of studies and disparate datasets track state energy storage polices, but these datasets do not cover all behind-the-meter (BTM) related storage policy. Moreover, these databases do not align these policies with the policy stacking framework. Thus, it is unclear what BTM storage policies are adopted across the country, what should comprise a complete storage policy framework or stack, and how states policies compare against that stack.

A new report by the National Renewable Energy Laboratory (NREL) addresses this gap in the literature by developing a state policy stack for BTM battery storage compared across all fifty states. This first-of-its-kind BTM storage policy stack includes 11 parent policy categories, and 31 associated policies divided across the market preparation, creation, and expansion policy components.

Speakers:

  • Jeff Cook, NREL
  • Todd Olinsky-Paul, Clean Energy States Alliance (moderator)

This webinar is a presentation of the Energy Storage Technology Advancement Partnership (ESTAP). ESTAP is a federal-state funding and information sharing project that aims to accelerate the deployment of electrical energy storage technologies in the U.S. ESTAP is funded by the U.S. Department of Energy Office of Electricity, managed by Sandia National Laboratories, and administered by the Clean Energy States Alliance.

Solving the Grid Connection Problem

Slides from this webinar are available as a pdf here.


As the energy transition accelerates, an unprecedented number of clean energy projects have applied to connect to the power grid. Even before new incentives provided by the Inflation Reduction Act (IRA), there were enough renewable energy generators waiting to connect to meet 80% of US demand, if they were all built. This flood of proposed projects has created unprecedented delays, with the average wait time for a permit now exceeding three years. In response, the Federal Energy Regulatory Commission (FERC) has opened a rulemaking to revamp the grid connection process.

In this Clean Energy States Alliance webinar, a panel of experts discussed the problem and what can be done about it. The webinar was moderated by CESA Senior Research Associate Ben Paulos. Speakers included:
• Joe Rand, Lawrence Berkeley National Lab
• Beth Soholt, Clean Grid Alliance
• Jeff Dennis, Advanced Energy Economy (AEE)

This webinar is presented by the Clean Energy States Alliance on behalf of the 100% Clean Energy Collaborative.

Advancing Solar for Manufactured Homes through Community Solar

Slides from this webinar are available as a pdf here


Manufactured homes, formerly known as mobile homes, comprise over 6% of the country’s housing stock and represent an even larger share of housing for low-and-moderate-income (LMI) families. Community solar projects have seen success across the country in bringing the benefits of solar to LMI homeowners, including those living in manufactured housing. However, because of cost and trust issues, it can be difficult for developers to deploy community solar – even with free subscriptions – to LMI households living in manufactured homes.

In this Clean Energy States Alliance webinar, panelists shared more information about how community solar can be used to bring the benefits of solar to manufactured homes; how to engage with the U.S. Department of Energy’s National Community Solar Partnership (NCSP); and successful examples of community solar projects that have benefitted manufactured homes and communities.

Panelists:
