VDER revisions provide a boon for solar-plus-storage
Greater certainty of value stack revenues good news for financiers and developers
• In April 2019, NYSERDA announced changes to the Value of Distributed Energy Resources (VDER) value stack. Overall, these changes create
greater certainty around the payment from different aspects of the value stack. Highlighted changes to the value stack include:
• Capacity (ICAP): Windows for alternative narrowed, fewer hours each summer but potential revenue remains.
• Demand Reduction Value (DRV): now paid on performance over a known peak window, varying by utility, which provides greater revenue
certainty. Each utility includes five-hour window during summer weekdays, aligning with ICAP model. DRV rates and time periods are locked in for
10 years, providing further certainty.
• Locational System Relief Value (LSRV): shifts to a call system where utility will now have at least 10 call events per year with 21 hours prior
notice and occur during the DRV window. Calls will last 1-4 hours with compensation based on lowest net kW output during the call window. A
project that fails to respond to a call shall not be subject to any penalty. LSRV value and time period will be locked in for 10 years.
• Lining up windows for ICAP Alternative 2 and the DRV creates a significant opportunity for solar-plus-storage
• Extending LSRV and DRV values to 10 years will allow that portion of the value stack to become more financeable thanks to greater revenue certainty
over project lifetime.
• Movement towards “smart” targeting of hourly needs incentivizes storage by recognizing its value.

Demand response capacity from utility operated programs continues to decline
DRAM resources comprise 23% of total demand response capacity in 2019
• Price-responsive programs are transitioning to Proxy Demand
Resources (PDRs) in day-ahead and day-of markets.
• Reliability-based programs are only triggered when CAISO declares an
emergency; these utility programs are transitioning to Reliability
Demand Response Resources (RDRRs) in the CAISO.
• RDRRs can only enter the bid stack when an emergency condition is
declared, at prices between $950/MWh to $1,000/MWh. RDRRs were
implemented in 2014.
• Decline in utility programs can be attributed to:
o The CPUC has mandate that the three investor owned utilities
switch customers to time-of-use rates starting in 2019, hence the
heavy decline in utility price-based program capacity.
o The demand response auction mechanism (DRAM) pilot total 203
MW in 2019. DRAM has taken customers away from utility
programs and into those of third parties since customers cannot
participate in both utility and DRAM demand response.

For the first time CAISO devotes a section to energy storage resources in the annual report
• As illustrated on the left, battery energy storage
capacity has been steadily increasing since 2015,
totaling 136 MW by the end of 2018.
• CAISO points out that “the majority of batteries
participating in ISO markets are located in locally
constrained areas.”
• Batteries are primarily receiving awards in ancillary
services providing including regulation (up and down)
and spin reserves.
• When providing energy, schedules are concentrated
during the ramping hours (evenings and mornings);
batteries are often charging at night and in the middle
of the day when production from renewables is the
highest.

payments
• In January 2018 the Annual Report Evaluating Demand Response
Participation in the CAISO for 2017 was released, covering the
period from January 1 through November 30, 2018.
• The report summarizes the payments made for the provision of
nonspinning reserves capacity and real-time energy. Year-over-year
there is an observed significant uptick in demand response activity. In
2016 demand response providers earned just under $0.5 million while
in 2017 payments increased nearly nine-fold to $4.2 million; in 2018
payments increased to $5.05 million.
*See California Independent System Operator Corp. 119 FERC ¶ 61,313, at P 226 (2007). The CAISO has filed annual reports on

• In February 2017 Sunrun announced that it had won a contract for 20 MW of
solar-plus-storage capacity through ISO-NE’s capacity market, competing directly
against conventional generation for the 2022 delivery year.
• The most critical takeaway here is that aggregation is happening today*.
• Success begets success, and DER and hybrid participation models will continue
to grow and evolve as cheap solar, storage, and other distributed assets explore
every avenue to provide value.
*The actual announcement was 5 months ago and the capacity will not be due until 2022 but these details make this statement much less impactful so using my analyst
discretion I have chosen to confine them to this footnote.
Sunrun’s bid in ISO-NE’s forward capacity market

The future of DERs in wholesale markets
FERC Order 841 provides a signpost for how FERC
may set the bar for DER aggregation

FERC Order 841: Timeline from NOPR to implementation
In November 2016, FERC released a
notice of proposed rulemaking
(NOPR) on integration of energy
storage and aggregation of distributed
energy resources into wholesale
electricity markets.
In February 2018 FERC unanimously
approved Order 841, which had few
substantive changes from the
proposed rules issued under the
earlier NOPR, with the exception that
the second part of the order, involving
aggregation of distributed energy
storage resources, was tabled for
future discussion.
In May 2019 FERC denied rehearing
requests and upheld the December
2019 time frame.
21. woodmac.com
FERC Order 841 compliance requirements
The foundational elements of the order were designed to ensure a level playing field for storage
FERC Order 841 requires ISOs and regional transmission organizations (RTOs) to modify their participation rules to ensure
energy storage is eligible to participate in all organized electricity markets. The new rules, comprising the four key areas
highlighted below, ensure that storage will be competing without a market handicap, as was identified by FERC.
22. woodmac.com
Strategies for resource definitions, the pathway to participation, vary dramatically
Multiple participation models remain the norm, creating a complicated and varied array of rules
Approaches vary in creating, changing, combining or splitting resource types to accommodate energy storage
Single resource definition:
• NYISO: Created Energy Storage Resource as a participation model, but some resources may be forced
to use the existing Energy Limited Resource (ELR) model, which is not directly in compliance with 841.
• MISO: Electric Storage Resource (ESR) will be created.
Multiple resource types:
• CAISO: Made a handful of compliance changes to its existing models
• PJM: Expanded on its Energy Storage Resource (ESR) and Capacity Storage Resource (CSR)
participation models.
• SPP: Created Energy Storage Resource (ESR) and Market Storage Resource (MSR)
On the fence:
• ISO-NE: Use cases are split into Binary and Continuous storage types, along with the existing Alternative
Technology Regulation Resource (ATRR), but the newly defined Electric Storage Facility is designed to
be able to participate as both.
23. woodmac.com
Eligibility for aggregated resources
• FERC’s initial notice of proposed rulemaking included aggregation, but tabled
• Initial interest suggests eligibility and “level playing field” a priority.
A technology agnostic approach
• FERC has repeatedly shown a desire to not “pick winners”
• Diversity of offerings may make this difficult
Hard pressure on ISOs for complete and timely implementation
A range of approaches varying by ISO
• FERC is comfortably with top-down mandates but bottom-up implementation
• Regulatory variety will be the name of the DER aggregation game
What lessons can we learn from FERC order 841?
If the aggregation question plays out similarly to storage it will be good news for DERs

• CAISO’s unique price curve presents an opportunity for multiple
arbitrage charge/discharge cycles per day.
• CAISO’s morning peak is significantly smaller than its evening
peak, but the additional peak and trough can be captured by
systems up to 4 hours in size.
• Capturing both peaks raises potential daily arbitrage revenue for a
4-hour system to $150.84/MW, up from $131.53/MW when
discharging to meet only the afternoon peak, a difference of
$19.31/MW.
• If the cost of the additional cycle – which would vary based on the
system’s lifetime and degradation rate – is below this $19.31/MW
value, then it may make economic sense for systems already
participating in CAISO’s market to attempt to capture this
secondary peak

In April 2019, NYSERDA announced changes to the Value of Distributed Energy Resources (VDER) value stack. Overall, these changes create greater certainty around the payment from different aspects of the value stack, which in turn will give financiers and investors greater confidence in solar-plus-storage or standalone storage projects taking the value stack, creating greater upside in the New York market.
Value stack changes apply to any projects that qualified after July 26, 2018. Changes to the value stack include:
Capacity (ICAP): Alternative 1 capacity values now based on published NYISO monthly prices using PV load curves to estimate expected ICAP contribution from fleet of distributed intermittent generation to determine number of kWh value should be spread over. Time window for Alternative 2 shifted to non-holiday weekdays from 2-7 PM from June 24 through August 31; this leads to a period of roughly 240 hours, a decrease from the previous 460 hours while in turn raising the compensation received in each hour. This new period is expected to better align with system peaks.
Demand Reduction Value (DRV): now paid on performance over a known peak window which provides greater revenue certainty. This portion of the value stack is based on an individual utility’s peak, and thus the window varies by utility, though every utility includes at least 5 afternoon hours from June 24 through August 31, thus aligning with ICAP Alternative 2. DRV rates and time periods are locked in for 10 years. Projects with dispatchable DER can opt out of the DRV and instead participate in a utility’s Commercial System Relief Program (CSRP), demand response programs that compensate based on response to an event call.
Locational System Relief Value (LSRV): shifts to a call system where utility will now have at least 10 call events per year with 21 hours prior notice and occur during the DRV window. Calls will last 1-4 hours with compensation based on lowest net kW output during the call window. A project that fails to respond to a call shall not be subject to any penalty. LSRV value and time period will be locked in for 10 years.
Market Transition Credit (MTC)/Community Credit (CC): paid to community DG projects, moving forward the MTC will be replaced by the CC. The CC is paid based on entire grid injection of a project regardless of the offtaker makeup (previously were stipulations requiring a certain proportion of small offtakers).
No changes were made to the Energy Location Based Marginal Price (LBMP) and Environmental value (E) portions of the value stack
Lining up windows for ICAP Alternative 2 and the DRV creates a significant opportunity for solar-plus-storage, as dispatchable resources will be able to maximize value stack remuneration for both of these options by aligning electricity injections to these periods. Furthermore, extending LSRV and DRV values to 10 years will allow that portion of the value stack to become more financeable thanks to greater revenue certainty over project lifetime. All told, these changes improve the case for solar-plus-storage under the value stack and create further upside in the New York market.
