SANTA BARBARA, Calif.–(BUSINESS WIRE)–Cementing its role as an industry trailblazer, Canndescent™ has completed the cannabis industry’s first, commercial-scale solar project, powering its indoor production facility in Desert Hot Springs, CA. Delivering onsite, renewable energy, the 282.6 kilowatt system uses 734 solar modules on seven different carport structures to energize the company’s historic cannabis production facility, which also earned attention in 2016 as California’s first municipally permitted operation. The state-of-the-art, clean energy system offsets as much carbon annually as a 430-acre forest and reduces annual atmospheric carbon emissions by 365 metric tons (per NREL and EPA estimates).

The BuildingEnergy Boston Conference + Trade Show is the region's leading event for professionals and practitioners in the fields of high-performance building, energy efficiency, and renewable energy. It brings more than 1,500 industry leaders and emerging professionals together to learn from and share ideas with each other. This year's event will be Thursday and Friday, March 14-15, 2019 at the Westin Boston Waterfront.
The theme of BuildingEnergy Boston 2019 is Know-How. This year's Conference Chairs are developing a session line-up that focuses on practical skills and immediately applicable knowledge—the innovations we're working on now, our recent lessons learned, the skills we wish all our colleagues had.
Throughout the country, we have seen rapid growth in the residential solar space supported by a wide range of industry players and solar offerings. However, growth has been slow in our low and moderate-income communities where the benefits of solar and energy efficiency services are more impactful. The goal of this session is to showcase various state approaches to bringing solar and energy efficiency resources to underserved communities and educate attendees about how these innovative solutions have been effective in doing so. We will highlight programs that offer a solar lease, solar loan, and community solar offerings.
This article is an excerpt from the new whitepaper published by Microgrid Knowledge and Enel X North America, California’s Changing Time-of-Use Rates: Calculating the Impact on Behind-the-Meter Solar PV and Energy Storage.
For utilities, electricity is generally more expensive and complex to deliver when demand is high. To help cover these costs, California’s utilities have traditionally imposed time-of-use (TOU) rates, which created a daily schedule that applies different prices for power based on demand trends on the grid. When demand is highest, prices are highest under TOU rates.
Developers have applied to build 139 GWac of large-scale solar projects in the territory of six grid operators – around five times what is currently online across the country – and that figure doesn’t even cover the entire United States. By any metric, we are looking at an unprecedented boom in solar development over the next five years.

Some of it is the pending drop-down of the Investment Tax Credit from the end of 2019 through the end of 2023. Some of it is a series of decisions by states, cities and corporations to decarbonize their electricity supply, and to use solar as a main means of doing this. And some of it is the continual decline in PV system prices, which makes large-scale solar the cheapest form of new generation in much of the United States.
But whatever the cause, there is an unprecedented, massive volume of solar projects that is underway in the United States. Research conducted by pv magazine USA has uncovered more than 139 GWac of solar projects which have applied for interconnection with six grid operators (CAISO, NYISO, ISO-NE, MISO, PJM, ERCOT) by the end of December 2018, spanning the Northeast, Midwest, California and Texas.
For perspective, Wood Mackenzie estimates that there was only 34 GWdc of large-scale solar online at the end in the third quarter of 2018. When you convert that figure to AC power, it means that the new capacity being considered is around five times as large.
There are other reports looking at upcoming capacity, and they do vary greatly – which ought remind us all that much of what is in a queue won’t move forward. ISO New England estimates that 70% of the projects in its queue never see the light of day.
However, more than 15 GWac of solar projects in these six grids either already hold interconnection agreements, or have entered the engineering and procurement phase.* The largest portion of these is in California, but there are also more than 4 GWac of projects in Texas that hold interconnection agreements.
Our investigation showed solar project development going truly national. In fact, the California Independent System Operator (CAISO) grid has a smaller volume of solar projects in its interconnection queue than the Midcontinent System Operator (MISO), Electricity Reliability Council of Texas (ERCOT) or PJM Interconnection, each of which have more than 32 GWac of solar projects in their queue. Unlike California, the large majority of project volume in all three has been proposed in 2017 and 2018 and these regions had all seen limited large-scale solar market development until a few years ago.
Even more to come
It is important to remember that these grids don’t cover the entire United States, and as such this 139 GWac does not include projects in the majority of the South, Mountain West, Pacific Northwest and Plains States. And we aren’t seeing these massive projects only in databases, either. As documented in pv magazine USA’s year-end coverage, we have found large solar projects either planned or under construction in 17 states that have not had substantial solar markets to date.
The signals of a boom to come in the U.S. solar market is reinforced by other data sources. The Federal Energy Regulatory Commission’s (FERC) monthly Energy Infrastructure Update(located under Energy Infrastructure tab) gives estimates of future capacity, and the latest report shows 63 GWac of proposed solar project additions before the end of 2021.
A quarterly report by Stephanie Tsao and Ellen Meyers of S&P Global Market Intelligenceestimates that the U.S. utility scale solar project pipeline through 2022 has expanded to 33.9 GWac.
In these estimates by S&P, grid operators reports and FERC, we are only talking about large utility-scale projects. These numbers do not include smaller systems such as rooftop solar either on the homes or businesses of utility customers. Data from other projections suggest that another 4-5 GWdc is coming from residential and commercial solar combined. Adding that volume to the S&P projections with a DC:AC ratio of 1.25:1 applied, suggests that the United States might build 18 GWdc of solar power in 2019, and just over 19 GWdc in 2020.
Energy storage boom
The six grid operator queues we investigated also showed more than 16 GW of battery projects which have filed for interconnection. And this number should not be too surprising to anyone who is watching the meteoric growth of energy storage.
Per the US Energy Storage Monitor, from Wood Mackenzie Renewables & Power along with the Energy Storage Association (ESA), total energy storage deployed expanded by 60% in terms of energy and 300% on a power basis in the third quarter of 2018 versus the prior year. Going out mostly until 2023, the report noted that the front of the meter pipeline expanded to approximately 33 GW of power.
The next five years are going to be truly massive for solar and energy storage. Hold on to your seats.
*Editor’s note: PJM Interconnection did not have a list of projects with interconnection agreements, but did list projects which had entered the engineering & procurement stage of development.

According to reporting from WBUR, the town council of Watertown, Massachusetts unanimously voted to approve a zoning ordinance requiring commercial real estate developers to put solar on new buildings.
