Selling SRECs from Solar Hot Water Systems

Posted May 18th, 2012 by SRECTrade.

It’s been a while since we last updated our readers on the fundamentals of SRECs for solar hot water (SHW) systems. Currently two markets, Washington DC and Maryland, allow for SRECs sold from solar hot water systems. There have been proposals to create SREC markets for SHW in other markets, but no other states have concrete plans to do so.

Key concepts:

SRECs from SHW systems are calculated by using the annual energy estimate provided by the Solar Rating and Certification Corporation (SRCC) OG- 300 Water Heating System Rating or by converting BTUs to kW-hr equivalents from BTU meters.  BTU meter readings are provided directly to the tracking registry (PJM GATS) in BTU’s and PJM GATS converts the BTUs into kilowatts.  Calculate kW-hr equivalents by multiplying system BTUs by .000293 and 1,000 kW-hrs = 1 SREC.

Maryland SHW Registration Rules

    • Must be located in MD
    • Only systems commissioned with passing plumbing inspections issued after June 1, 2011 or later are eligible
    • Single dwelling residential systems are capped at 5 SRECs per year
    • Commercial systems are not capped
    • SHW systems cannot be used for heating a pool or hot tub
    • Systems must be certified by the SRCC OG-300 reporting protocol or have an International Organization of Metrology (OIML) compliant meter
    • SHW modules must be SRCC OG-100 compliant

District of Columbia SHW Registration Rules

    • Must be located in DC
    • Residential system must be SRCC OG-300 certified
    • Commercial systems producing >10,000 kW-hr equivalents must be SRCC OG-100 certified and have an OIML compliant meter
    • Commercial systems producing <10,000 kW-hr equivalents must be SRCC OG-100 certified, have an OIML meter or be certified to the SRCC OG-300 reporting protocol

If you’d like to utilize SRECTrade to monetize SRECs produced from SHW systems in either MD of DC please fill out this application and follow the directions on the form.

Solar Thermal SRECs in DC – Update

Posted April 12th, 2011 by SRECTrade.

Recent legislation passed by the council of the District of Columbia now allows non-residential solar thermal systems to be registered to produce DC SRECs. Under the new legislation non-residential systems must be SRCC OG-100 certified. The legislation went into effect on March 12, 2011 and will expire on October 23, 2011. Previously the District only accepted SRECs from residential SRCC OG-300 certified solar thermal systems.

The new legislation has the following requirements for solar thermal systems:

Solar thermal non-residential systems producing or displacing more than 10,000 kW-hrs per year must be SRCC OG-100 certified and the annual energy output must be determined by an onsite OIML compliant meter.

Solar thermal non-residential systems producing or displacing 10,000 kW-hrs or less per year must be SRCC OG-100 certified and their annual energy output can be determined by the SRCC OG-300 performance rating protocol OR by an onsite OIML compliant meter.

Residential SRCC OG-300 certified solar thermal systems are not affected by this legislation and can continue to be registered in DC.

Given the current supply dynamics of the DC SREC market, this legislation will continue to provide more supply to the oversubscribed program. While SREC prices could continue to decline in the near term, it may be beneficial for solar thermal system owners, previously not eligible for the DC market, to register and receive certification as an option for potential SREC liquidity.

For an update on the current capacity certified to produce DC SRECs see the SRECTrade SREC Markets Report: March 2011.

Additionally, the Distributed Generation Amendment Act of 2011, could have a positive impact on the oversupplied DC SREC market. The legislation is still pending and details associated with the cut off date for grandfathering in out of state DC registered systems are still unknown. SRECTrade will continue to monitor this piece of legislation and provide additional information as it becomes available. For more background on the proposed amendment see these blog posts:

Solar Thermal SRECs in DC – Update

Posted November 12th, 2010 by SRECTrade.

The Washington D.C. Public Services Commission has recently clarified the requirements associated with registering Solar Thermal facilities to be eligible for the D.C. SREC market.

Moving forward, all eligible systems must be certified by the Solar Rating and Certification Corporation (SRCC). Specifically, the system has to be SRCC OG-300 certified.

The Washington D.C. Public Services Commission has indicated that any changes to the eligibility requirements would have to be made by the legislature, not the public services commission.

Solar Thermal SRECs in DC

Posted May 13th, 2010 by SRECTrade.

SRECTrade recently began registering solar thermal facilities in Washington DC and North Carolina.  The North Carolina program is in the final stages of being setup and we will provide more information when it is available.  Meanwhile, we’ve already sold our first solar thermal SRECs in the DC market at $290.  Here are some guidelines and information in regards to the requirements to register solar thermal systems in Washington DC:

Are solar thermal SRECs valued the same as solar photovoltaic SRECs sold in auction?
Yes, in DC and NC, solar thermal facilities can be approved to generate SRECs that have the same value to buyers purchasing to meet state compliance requirements.  Any auction for SRECs in DC will include solar PV and solar thermal SRECs sold at the same price.

What if my facility is not eligible in Washington, DC or North Carolina?
Both DC and NC allow out-of-state facilities to qualify, so many states are eligible to sell into these markets.  If your state is not eligible to sell into DC or NC, then the RECs produced by your facility have no value to buyers in the state compliance markets (i.e. our buyers).  You may still however be able to find ways to sell the RECs in voluntary or non-solar compliance markets – also known as generic REC markets.  There are companies out there that may help.

What else should I know about selling SRECs as a solar thermal facility?
Keep in mind the DC SREC market is a relatively small market and could someday be oversubscribed.  We are hopeful that the market for solar thermal SRECs will grow beyond DC as other states follow suit, however, as with any markets, there are risks associated with the market value of SRECs in DC.

What are the requirements for reporting production and generating SRECs?

Residential:
System must be SRCC-300 rated.  Here’s the link to the approved systems if you don’t already have it: http://securedb.fsec.ucf.edu/srcc/annual_search.  DC will used the energy saved in kWh as your generation for the year.  For example, a 2400 kWh system would receive 200 kWh per month and once the accumulation hits 1000kWh an SREC will be credited to their account

Commercial:
1.  Displaces < 10,000 kWh per year – can use SRCC 300 rating, SRCC-100 panel rating, or use an OIML meter
2.  Displaces > 10,000 kWh per year – must use OIML approved meter

Here are the exact details of the requirements from the Clean and Affordable Energy Act of 2008:

(1) For nonresidential solar heating, cooling, or process heat property systems producing or displacing greater than 10,000 kilowatt hours per year, the solar systems shall be rated and certified by the SRCC and the energy output shall be determined by an onsite energy meter that meets performance standards established by OIML.
(2) For nonresidential solar heating, cooling, or process heat property systems producing or displacing 10,000 or less than 10,000 kilowatt hours per year, the solar systems shall be rated and certified by the SRCC and the energy output shall be determined by the SRCC OG-300 annual system performance rating protocol applicable to the property, by the SRCC OG-100 solar collector rating protocol, or by an onsite energy meter that meets performance standards established by OIML; and
(3) For residential solar thermal systems, the system shall be certified by the SRCC and the energy output shall be determined by the SRCC OG-300 annual rating protocol or by an onsite energy meter that meets performance standards established by OIML.”.

Hopefully this clarifies the solar thermal process in Washington DC.
