Andrew Savage

Andrew Savage is the Chief Strategy Officer at AllEarth Renewables, manufacturer of the AllSun Tracker, where he oversees public affairs, communications, and strategic business development initiatives. He serves on the Board of Directors of the Solar Energy Industry Association (SEIA) as the vice chair of the Distributed Generation Division. Andrew also serves on Renewable Energy Vermont’s legislative committee (as 2011 and 2014 chair) where he helped develop and pass Vermont’s first-in-the-nation solar registration program, net metering expansions, and statewide solar adder. The registration program was named one of the Interstate Renewable Energy Council’s “Top 10 Notable Policy Developments of 2011” and Vermont's solar deployment has quadrupled in the three years since these policies were enacted. He has presented at PV America, the Department of Energy SunShot summits, NESEA Building Energy Conference, among others. Previously, Andrew was deputy chief of staff and legislative director for Vermont Congressman Peter Welch, a member of the Energy and Commerce Committee, where he managed the Congressman’s legislative team and helped author a U.S. House-passed $6 billion national energy efficiency retrofit program known as "Home Star." He was also part of President Barack Obama’s successful 2008 presidential primary campaign team. Andrew received his bachelor’s degree in political science and environmental studies from Middlebury College graduating summa cum laude.

Making Projects Happen with Group Net Metering Policies

By: Andrew Savage,

Almost every state in the country has net metering laws on the books.

But only a few states allow a lesser-known policy that is critical for the expansion of distributed renewables, particularly community-scale solar — that’s aggregate, virtual, or group net metering.  And there are a lot of good reasons to want to see its expansion.

The basic premise is that the output of a renewable system can be shared among accounts.  An extension of this policy is allowing multiple electric customers to share in a net metered system’s output.  This is often referred to as “community net metering,” “aggregated net metering,” “virtual net metering,” or “group net metering.”

However, whatever you want to call the policy, looking at the small number of states that permit such net metering reveals a myriad of unnecessary exclusions and caveats which limit their effectiveness — and the amount of net-metered solar.

For example, New Jersey’s policy adopted this month is restricted only to public projects.  Pennsylvania’s version is called “aggregate virtual net metering” and is limited to individual customers who own multiple meters within a two mile radius.  California allows for sharing of credits for multi-tenant properties and also for local governments, but only if all participating accounts receive a time-of-use rate. 

But for something shared so virtually as an electron, one needs to ask why these policies include so many unnecessarily restrictive caveats based on things like geographic distance and customer class.

It’s an important enough issue that the net metering report, Freeing the Grid, recognizes aggregate and group net metering policies as key ranking indicator when evaluating states.

Vermont has the most advanced and solar-conducive policy.  It started with the concept of allowing multiple farm buildings to join a “group” for on-site generation, Vermont’s expanded “group net metering” law allows offsite generation up to 500 kW (2.2 MW for military). The only requirement is that members be in the same electric utility.  That’s it.  Groups may be mixed among residential, commercial, and government customers.  Local utilities must reward credits and bill net metering customers within a group directly.  And, notably, Vermont’s law recently provided time-of-use customers a consistent method for crediting their net metered production.  The system has proven efficient, easy, and most importantly encourages net metering.

Why is getting this policy right so important?  The expansion of policies like group net metering help dissolve the traditional boundaries of distributed electric generation and are critical for facilitating the expansion of solar net metering. 

Choosing the most productive sites:  Group net metering allows installers, investors, and customers to choose the best possible site for a renewable energy system.  Rather than being boxed in to a less-than-adequate roof or a geographic space too small or too shaded for the most cost-effective net metered projects, group net metering allows for ideal siting, making for a better investment with higher financial returns.  Further, group net metering allows for greater flexibility when considering local planning, zoning, or historical requirements.  Take for example two homeowners with inadequate roofs for solar.  Under Vermont’s group net metering law, those two homeowners could easily join with a third neighbor or businesses and share the energy from a solar tracker installed at a more productive, economical site.

Achieving economies of scale: While traditional net-metered solar often makes a lot of financial sense, group net metering laws allow for economies of scale in larger project development.  According to the Department of Energy, the average residential cost of solar is approximately $6/watt nationally.  Meanwhile, larger scale distributed solar projects cost $3/watt (for fixed solar) or even below.  Consider also that land values vary dramatically even within the same electric utilities, and you see how installing a site a little way down the road can also have a significant impact on financials of a project.

Creative solar finance:  Group net-metering policies facilitate community solar projects and third-party ownership models, expanding opportunities for customers.  As SunRun, Sungevity and other third-party ownership models have demonstrated, innovative solar financing has proven widely successful in deploying residential net metered solar.  This innovation continues with companies like Solar Mosaic who are creating mechanisms for “crowdfunding” projects, where individuals can directly make renewable energy investments.  Promising new initiatives are enhanced by conducive local policies. 

Reduced default risk:  For states that allow third party or Power Purchase Agreement (PPA) investors to offer group net metering, these policies reduce the risk to an investor because should a net metering customer suddenly not have an electric load (a school closes, for example) or not be able to pay (in the case of a bankruptcy), the PPA agreement could be fashioned so that the energy output from the project could simply be transferred to a new customer within the utility if allowed under group net metering law. 

More solar for more customers:  Group net-metering policies help enable non-homeowners to invest in solar and have also facilitated the proliferation of solar programs for affordable housing tenants.  For example, California’s Multifamily Affordable Solar Housing (MASH) Program, was designed in 2008 specifically for low income affordable housing and the California Public Utility Commission reported earlier this month that virtual net metering has allowed thousands of low income tenants to receive the direct benefits of solar as reductions in their monthly electric bills.

In sum, aggregate, virtual, and group net metering polices allow for the expansion more efficient, economical projects to provide renewable energy to an increasingly diverse customer.  It key, though, to get the policies right.

State policies and individual utilities should look hard at how to dissolve the traditional, unnecessary boundaries in the industry. Such a policy shift could quickly usher in a brighter distributed renewable energy future.
