Formulate investor case:
  • 20 year outlook -> asset value
  • Curtailment risks
 
Negotiate offtake
  • Market strategy: PPA vs merchant
  • Regulated strategy: rate benefit -> PUC approval
DESIGN -> INTERCONNECT
DESIGN -> INTERCONNECT
Identify tech risks:
  • Voltage/thermal risk: dynamic, transient
  • Harmonic assessment
  • Controls interaction: multi-plant, HVDC
 
Design system/mitigate risk:
  • Interconnect design: AC or DC
  • Tune equipment: controls, converter
  • Network: synchronous condensers, statcom
OPERATE PROFITABLY
OPERATE PROFITABLY
Analyze performance: curtailment, upgrades
Schedule maintenance: market-based
Maintain compliance: NERC model validation, and protection coordination

GE MAPS* Database: Generation

The four technology types parameterized

Thermal (coal, gas) (CC/CT)
THERMAL
  1. Capacity: min/max MW, heat rate curve, duct firing
  2. Fuel: type, emissions rates
  3. Economics: capex, startup, variable O&M, fuel price forecast
  4. Operation: min up/down, must-run, outages (planned/random)
Renewable (wind, utility PV)
RENEWABLE
  1. Capacity: MW nameplate
  2. Resource: day ahead + real time hourly forecast … historical data
  3. Economics: PTC-based bids, capex outlook
  4. Operation:  curtailment, outages
Hydro (reservoir, run of river)
HYDRO
  1. Capacity: Min / max
  2. Resource: monthly energy forecast … typically 10 yr hist avg
  3. Economics: min bid price
  4. Operation: intraday cycling possible 
Storage (battery, pumped)
STORAGE
  1. Capacity: MW + MWH 
  2. Tech: charging losses 
  3. Economics: capex outlook, bid floors/caps
  4. Operation: weekly or daily charge/discharge cycle

Transmission model

Transmission can have a significant influence on price.

Standard Approach
Standard Approach
Zonal price scenarios
~200MB
Power flows between zones
GE MAPS* Approach
GE MAPS* Approach
Nodal price scenarios
~2,000,000MB
Power flows within & between zones

The transmission model:
bringing physics into financial modeling

The ideal grid: how the circuit directs power
RTO-sourced: annual update, CEII access req’d
Four main elements: gen, loads, nodes, lines … GE PSLF* model
Specs: Node #’s, MW ratings, impedances
vs. the real grid
The real grid: reliability rules/exceptions
GE EC intel: decades of RTO research, NDAs req’d
  1. Contingencies: grid balance w/ outages (N-1)
  2. Interface limits across multiple lines (MW & V)
  3. Operational exceptions: Must-run units, underground line exceptions, local req’ts
vs. the ideal grid
