Community Solar On The Rise | Earth Wise

By Leave a Comment

Community solar is a way for people who can’t put solar on their own roofs to still take advantage of its benefits.  Whether they can’t afford to install their own panels, have too much shade on their roof, or don’t even own a home, community solar is another way to participate in green energy.

Community solar – also called “shared solar” or “solar gardens” – is a kind of development in which consumers can subscribe to a large solar installation in their area and receive credits on their monthly utility bills for their share of the solar electricity produced.

The large majority of community solar installations are in six states:  Colorado, Illinois, Massachusetts, Minnesota, New Jersey, and New York.  After substantial growth in community solar in 2022, New York now is the national leader, thanks to initiatives by the state government and the nonprofit sector.  Some programs focus on giving low-income households access to solar.  As of last fall, New York had over 728 community solar projects online.

One should understand that electrons are indistinguishable.  The power generated by a community solar installation is not piped directly to subscribers’ homes.  It just goes into the grid.  Subscribers get credit for their share of the power, but that is essentially a matter of bookkeeping, not physics.

The federal government now has $7 billion that can be used for community solar as part of the Greenhouse Gas Reduction Fund within the Inflation Reduction Act enacted last August.  The EPA plans to award up to 60 grants to assist projects deploying residential and community solar.  Research firm Wood Mackenzie forecasts the community solar market will double by 2027.

Community Solar In New York | Earth Wise

By Leave a Comment

New York has now installed 1 GW of community solar capacity, which is more than any other state.

Community solar is a solar energy project within a geographic area for which the benefits flow to multiple customers such as individuals, businesses, nonprofits, or other groups.  For the most part, the customers benefit from energy being generated by solar panels located at an off-site array.  Customers typically buy or lease a portion of the solar panels in the array and then receive an electric bill credit for the electricity generated by their share of the community solar system.  It is a great option for people who can’t install their own solar panels because they don’t own their home, don’t have a suitable location for various reasons, or have financial constraints.

Community solar in New York now generates enough electricity to power 209,000 homes.  Community solar installations accounted for 70% of New York’s solar additions in 2021 and the state has a pipeline of 708 more projects totaling 2.3 gigawatts.

The NY-Sun program run by NYSERDA since 2011 has directed over $200 million to low-to-moderate income households as part of its Solar Energy Equity Framework. 

Growing community solar depends strongly on policy expansion.  At this point, 19 states and D.C. have established policies and programs to support community solar adoption.  The federal government set a goal of powering 5 million American homes with community solar over the next five years.  With 30% of the country’s current community solar capacity, New York is leading the way.

Clean Energy In Rochester | Earth Wise

By Leave a Comment

New York’s largest community choice clean energy program has been activated in the City of Rochester.   The program, offered by Rochester Community Power, offers 57,000 residences and small businesses access to clean energy from hydropower and wind sources.  It requires customers to opt out rather than enroll in order to provide clean energy to the greatest number of people.

Rochester Community Power is the city’s local community choice aggregation (CCA) program that leverages the collective buying power of participating residents to purchase renewable electricity and negotiate better terms for energy supply contracts.

The program will supply customers with more than 300 million kWh of renewable energy each year, which will avoid the emission of about 250,000 tons of carbon dioxide.  Rochester plans to add a community solar program next year which will provide additional clean energy opportunities, including offering guaranteed savings to thousands of participants in its Home Energy Assistance Program.

The project will be managed by Joule Assets, which is a provider of energy reduction market analysis, tools, and financing. Joule Assets, as program administrator for the Rochester program, managed the competitive bidding process that secured a fixed rate for electricity for the next two years, shielding participating residences and businesses from volatile market prices.

Community choice aggregation programs are local, not-for-profit public agencies that are an alternative to investor-owned utilities.  They give municipalities the ability to make decisions about the procurement, sourcing, and rates for energy for its residents.

30 Million Solar Homes | Earth Wise

By Leave a Comment

A national coalition made up of more than 230 organizations has launched an initiative called the 30 Million Solar Homes campaign.  The goal is to add enough rooftop and community solar energy to power 30 million homes across the U.S. over the next five years.  That would be the equivalent of one in four American households.

The major focus of the 30 Million Solar Homes initiative is to rapidly and massively scale programs that help low-income families benefit from solar power.  The coalition lists 15 federal policy initiatives including making solar tax incentives more equitable, providing more reliable low-income energy assistance through solar energy, supplementing low-income weatherization assistance with solar energy, and specifically funding solar projects in marginalized communities.

The federal government spends billions of dollars every year to help families to pay their energy costs, but these efforts only serve less than a fifth of the eligible population.  Funding rooftop and community solar access for these households would provide long-term financial relief and reduce the need for annual energy bill assistance.

The more than 230 organizations in the coalition represent organizations focused on energy equity, climate, business, environment, faith, and public health.  The coalition estimates that executing the plan would create three million good-paying jobs, lower energy bills by at least $20 billion a year, and reduce total annual greenhouse gas emissions by 1.5%.

Over the coming months, the campaign will seek to educate lawmakers and the Biden-Harris Administration about the benefits of distributed solar energy.  The vision outlined by the coalition is an ambitious one to say the least.

Community Solar With Storage In New York | Earth Wise

By Leave a Comment

Community solar allows members of a community to share the benefits of solar power even if they cannot or prefer not to install solar panels on their own property.  There are several models for how community solar works, but all of them allow members to benefit from solar power being generated by an offsite solar array by effectively allocating a portion of its output to them.  In any event, community solar can save money on electric bills and allow people to make use of renewable energy for their needs.

A next step in the evolution of a decentralized energy system is incorporating energy storage into community solar projects.  The first one of these in New York State has now been completed in Yorktown Heights in Westchester County.  The project consists of 557kW of rooftop solar in the form of nearly 1,500 solar panels paired with 490kW of four-hour Tesla Powerpack battery energy storage.  The system is expected to provide 150 participants with approximately 10% savings on their monthly electric bills over 25 years, as well as providing power to 12 Tesla electric vehicle charging stations.

The project was funded by NYSERDA, under its Retail Energy Storage Incentive program, which currently includes 50 community solar-storage paired projects across New York State that are expected to be installed in the next two to three years.

New York has been actively promoting community projects in support of goals announced by Governor Andrew Cuomo to install 6,000MW of solar in the state by 2025 and 3,000MW of energy storage by 2030.

The Largest Community Solar Program

By Leave a Comment

Community solar projects allow customers to benefit from the economic and environmental attributes of solar energy when they don’t have the ability to invest in their own system for any number of reasons.

Florida Power & Light company is proposing to build the largest community solar program in the United States, pending regulatory review.  The planned installation of 1,490 MW of new solar capacity at 20 new power plants distributed across FPL’s service territory is expected to generate an estimated $249 million in net savings for all FPL customers over the long term.

In addition to becoming the largest community solar program in the country, the new program would also be the largest voluntary low-income solar offering in the country.  Low-income households are typically unable to benefit from solar energy because of not having the means to invest in the technology.  The new SolarTogether program will have more than 35 megawatts of capacity dedicated to low-income Florida families.  Solar energy is a critical tool for enabling low-income families to tap into energy savings. 

The SolarTogether program would provide direct savings in the form of bill credits, making solar an affordable option for any customer.  The Southern Alliance for Clean Energy and Vote Solar joined with FPL to help design the program to include a low-income component and request Florida Public Service Commission approval. There is broad support for the program from universities, county and city governments, and private companies.  In addition, more than 90,000 residential and small business customers have already signed up to receive more information.  The utility hopes to receive regulatory approval in time to launch during the first quarter of 2020.

Capital Region Community Solar

By Leave a Comment

New York’s Capital Region is getting a major new community solar farm.  A community solar farm is a solar power installation whose output is shared by multiple community subscribers who receive credit on their electricity bills for their share of the power produced.  The primary purpose of community solar is to allow members of a community to have the benefits of solar power even if they cannot or prefer not to install solar panels on their own property.

US Light Energy has broken ground on the Sugar Hill Solar Farm, to be located on 40 acres of land on the Sugar-Hill/Sugar-View Farm in Clifton Park.  The 7-megawatt, ground-mounted solar project will include nearly 20,000 solar modules.  When fully operational later this year, the facility is expected to produce more than 8.6 million kilowatt-hours of energy a year.

The farm will be part of New York state’s Community Solar Program, and the electricity it generates can be supplied to customers anywhere in National Grid’s existing distribution system.  Residential and commercial properties in Clifton Park will have 30 days to subscribe before the solar energy generated by the farm is opened to the general public.  Subscribers of community solar farms typically save 10% on their electricity bills.

There are already community solar programs in operation in several Capital Region communities, but this is the first one in the Clifton Park Area.  Apart from providing savings on utility bills, community solar allows consumers to support clean, locally generated power with little or no upfront costs.  Not everyone is in a position to put solar panels on their roof, but community solar is increasingly an option for New York residents.

Solar Equity for Low-Income Communities

By Leave a Comment

A couple of years ago, the number of American roofs covered with solar panels passed the one million mark and the numbers keep growing.  But nearly half of U.S. households – accounting for more than 154 million people – aren’t able to host their own solar arrays because they lack suitable rooftop space, or they rent their homes.  But millions more simply can’t afford to spend tens of thousands of dollars to buy or lease solar panels.

In recent years, community solar has become popular.  These are projects where multiple participants own or lease shares in a mid-sized solar facility and receive credits that lower their monthly utility bills.  Community solar in the U.S. has more than quadrupled just since 2016.

However, the majority of community solar subscribers to date have been businesses, universities, government agencies, and higher-earning households.  These users can generally pay steep project enrollment fees or meet various financial requirements.  Meanwhile, those who could benefit most from access to renewable energy and lower utility bills – low-income residents – have largely been left out.

Low-income households on average spend over 8% of their income on utility bills, about three times more than moderate- to high-income households.  So, reducing electricity bills with community solar power is a big deal for them.

Given this situation, there are now a growing number of programs that make use of community solar to reduce living expenses for low-income households.  In a dozen states, new programs include a variety of mandates, financial incentives, and pilot programs targeting benefits for people with low incomes.  These programs will allow them to participate in both the environmental and economic benefits of renewable energy.

Capital Region Community Solar

By

Community solar is a cooperative enterprise in which customers can make use of the output of a large local array of solar panels when they are not able to install a solar power system on their own property.  The customers of a community solar system can offset as little or as much of their electrical usage as they want by participating in a community solar program.
