Connecticut | Connected Solutions Flashcards
market intelligence, incentive program
Connected Solutions (CS):
- Based on __ energy consumption during ___ compared to __ (discharge during CS hours on non-event days will * decrease baseline and thereby decrease potential revenue from this program)
- No penalty if event-day load exceeds baseline load during CS hours
Decreasing, event days, baseline load
* Basically if one uses less electricity during low-demand hours it will decrease the baseline
* no penalty if you end up using more than usual during CS hours, the program is focused on encouraging saving not higher use
CT ESS
CT’s program other than CS, cannot co-participate in both
CT ESS reqs: (there are 3)
CT ESS is both an ___ and a ___ incentive.
- 10 year warranty (manufacturers must guarantee their ESS works for 10 years for people who purchase or install the ESS)
- must be able to island: “island” bc ESS must be able to operate independently during outage (ESS can disconnect, supply independently when main grid fails, sort of acting like a mini grid)
3.No co-participation with CT CS: prevent double-dipping in both programs.
Both an upfront and performance-based incentive
ISO-NE Forward capacity market
- which CT program is this under?
literally just future-electricity-provided market, where future electricity bough and sold in new england (NE)
CT ESS, it’s a constraint for performance-based section of incentive
“Qcells does not take a cut from the upfront incentive of CT ESS”
- where did this appear?
CT ESS
when a customer install ESS, Qcells doesn’t take a cut from the incentive given to customer; so customer gets to keep full amount
How does CT ESS”s performance-based side incentive work?
- based on active dispatch windows instead of passive dispatch
- based on ave power during events (peak demand) (kW)
***This means the performance incentive is calculated based on how much power (in kilowatts, kW) your energy storage system discharges during these active dispatch events. It’s not just about using less power during peaks; it’s about how much power your system can provide to the grid (or offset from the grid) during these critical times.
- based on ave power during events (peak demand) (kW)
- Only when ISO-NE forecasts grid capacity constraints (notifies customers 24 hours in advance)
How does CT ESS’s upfront incentive works?
- Upfront incentive $100-300/kwh with adders for critical facilities, circuits with frequent outages, C&I customers replacing fossil fuel generators, and small businesses
– if you install like 10kwh capacity ESS, you get like 1000-3000 bucks upfront
— Adder = additional money given beyond upfront incentives, like bonus
— Critical facilities = crucial facilities that have to remain powered during outage, like hospitals
– so if critical facilities install an ESS (remember they can island), installer get extra money
Active Dispatch window vs. passive dipatch
AD: refers to specific times when the energy storage system (like a battery) is actively used or ‘dispatched’ to either provide power or reduce power consumption from the grid. These windows are usually determined by the program administrators and are based on when they predict the grid will need extra support (like during peak demand times).
PD: This is when the energy storage system operates automatically based on pre-set rules or conditions, without specific instructions from the program administrators. It’s like setting your home thermostat to lower the temperature at night automatically.
how does NRES distinct from ESS and CT?
hint: while ESS and CT focuses on ___ and ___, respectively, NERS focuses on ___
energy storage, demand reduction, generating electricity using solar panels
!! In one sentence, say how the 3 CT incentive programs are different
ESS is about STORING energy at specific times, CS is about reducing demand at peaks (it’s about dispatching), and NERS is about rewarding actual production of renewable energy.
AS Market
Ancillary Services Market
*a market where services necessary for supporting transmission and maintaining grid stability are bought and sold, such as— frequency regulation, spinning reserve. Usually only provided to FTM standalones. no BTM has AS market in their value stack, and no FTM PV has this in their value stack- only FTM standalones (because renewable energy distribution/transmission with AS is complex)
Frequency Regulation:
refers to ESS being paid for their rapid response to adjust output to grid’s required level when needed, so grid stability and safety is maintained. – part of AS market, applies to FTM standalones only
Spinning Reserve
ESS offers a backup supply of power that can be bought and sold quickly if a generator goes down or if there’s sudden demand decrease , part of AS market, applies to FTM standalones only
TOU
Time of Use: a pricing mechanism that depends on when the peak hits.
CT Energy Optimization Objective
Energy Optimization Objectives: DCM and TOU: both are “proportional to the % of the passive dispatch period overlap with TOU period” for energy saving
