Pdf of presentation from the American Solar Energy Society Solar 2022 conference in June.
Abstract from the proceedings paper referenced:
One critical component of a sustainable “Community Solar” * model in Texas is making it attractive enough to customers that projects can be developed without subsidies or grants.
To address energy poverty issues, TRCSS’ goal is to generate
enough revenue that a portion of each project group can be offered to local Low to Moderate Income residents with reduced cost participation options.
TRCSS was awarded a National Community Solar Partnership Technical Assistance grant in 2020 and has continued to investigate the potential for adapt ing energy trading concepts to Community Solar at three levels:
1) Wholesale markets: Smaller
projects aggregated to sufficient size that power can be sold through the ERCOT real time, day ahead, and long term markets using tools and practices already in use for some large merchant projects;
2) Commercial and industrial retail (C&I) markets: Smaller projects and some large single site
installations might be managed using tools and practices already in use by energy managers and Sustainable Energy as a Service contractors or directly by Retail Electric Providers, Municipal Utilities, and Cooperative Electric Utilities;
3) Smaller C&I projects might use
emerging tools and practices
leveraging “Blockchain Transactive Energy” standards.
*“ Community Solar” has a component of own ership by the local community.

Agenda
5. Section 1: Overview of Texas
Energy Deregulated Market
5
May 2022
• 1,800+ market participators
• 1,030+ generating units
• 92,000+ MW summer peak
demand
• 11,462 MW installed solar 14.6%
6. Texas Community Solar Projects
6
One of TRCSS’ goals is to update this
map with data from the National
Renewable Energy Lab (NREL)
Community Solar database
7. Overview Summary
7
• Texas Deregulated Energy Market is COMPLEX.
• Community Energy Trading is in its infancy of trial &
error with Commercial / Industrial /Municipal markets.
• Blockchain energy transactional management tools are
in development but not widely used.
• Success to date has only been in municipal or Co-Op
operations.
• Research by TRCSS continues
8. Section 2: Wholesale Markets in the
Electric Reliability Council Of Texas
(ERCOT) Region
8
• Wholesale markets in ERCOT are
important for adding to the value stack
for Community Solar in Texas
TRCSS will continue
to investigate.
9. Section 3: Commercial, Industrial, &
Municipal Markets (CIM):
Energy Brokers
9
• CIM markets in ERCOT are important
for adding to the value stack for
Community Solar in Texas
TRCSS will continue to investigate.
10. Section 4: Small Projects & Blockchain
Transactive Energy
10
• For projects too small for wholesale markets or traditional CIM energy
brokers, one path TRCSS is investigating is aggregation of DERs
“Distributed Energy Resource Aggregations in
Wholesale Markets”
• Another technology for small project energy trading uses peer-to-peer
(P2P) transactions
“Peer-to-Peer Electricity Trading Innovation
Landscape Brief”
• The term “transactive energy” is used to refer to a range of digital
technologies including both “cloud computing” and “Blockchain
Transactive Energy” (BCTE).
• TRCSS is focusing on BCTE.
11. 4.1 – IEEE Blockchain In Energy
11
• TRCSS has been participating in the IEEE
P2418.5 Blockchain In Energy Proposed
Standard Working Group and Use Cases
Task Force as part of TRCSS’ efforts to
stay current with developments in
standardization.
• The IEEE Transactive Energy Systems
Conference (TESC) held in 2022, which
TRCSS attended (virtually) had a number
of relevant sessions.
• Another useful recent IEEE reference is
from the Innovative Smart Grid
Technologies (ISGT) 2022 Conference:
“Blockchain in Energy As A Venue for
Electricity Grid Modernization” panel
session, 2022/04/25.
• The IEEE Blockchain Initiative has an
Energy Focus section.
12. 4.2 - Existing Blockchain Transactive
Energy (BCTE) Organizations
12
• Powerledger:
• LO3 Energy:
• Electron:
• Energy Web:
• WePower:
Examples of leaders in BCTE are listed in the Executive Summary from a
Guidehouse Report *
* “Analyst Insight: Top 5 Energy Blockchain Vendors” website
14. 4.4 - Texas Implementation Strategies
14
• TRCSS is exploring unique implementation opportunities for
Community Solar that the ERCOT deregulated operating
region provides.
• Many of them are already in use with utility scale projects.
• The challenge for TRCSS is how to develop and implement
local Community Solar projects without the overhead
expenses making them prohibitively costly compared to utility
scale options.
• For example, it is relatively easy to register as a Retail Electric
Provider (REP) in Texas and then be able to buy electricity
from generation entities and sell that power at competitive
rates to residential, commercial & industrial (C&I), &
municipal customers.
15. 4.5 – Other Technologies
15
• Cloud Computing is an approach to managing energy data
that may compete with Blockchain and Web 3.0
applications.
• This was discussed by Astrid Atkinson, CEO & co-founder,
Camus Energy, who presented this approach at a recent
Energy Systems Integration Group (ESIG) presentation on
DER Modeling & Distribution Systems Operations:
• Energy Systems Integration Group
(ESIG) webinar “DER Modeling and
Distribution System Operations”
16. 4.6 - Small Projects & Transactive Energy
Misc
16
• Yale openlab open-solar is
an interesting and
innovative approach to
democratizing energy using
Blockchain for financing
Community Solar:
• Raise Green is a climate
action investment platform
that includes Community
Solar in its project types:
17. Section 5: Conclusions & Next Steps
17
• Community Solar is difficult to develop in the Texas
deregulated market.
• Blockchain transactive energy is being successfully used in
other energy markets but not yet in Community Solar in
Texas.
• TRCSS will continue to investigate opportunities in
wholesale markets.
• TRCSS will continue to investigate opportunities in CIM
markets
