Energy Price Calculator

Whether you want to sell electricity (SELL CONTRACT) or buy electricity (BUY CONTRACT)

EnergyCalc calculates the value of your Contract against the Forecasted WESM Spot  Price, on a Base Case Scenario, for the entire contract duration.

 

EnergyCalc helps you: 

  • Quantify the risk and reward of entering into a contract 

  • Determine the optimal contract price

  • Leverage in negotiating energy price

  • Make quantitative decision in buying and selling energy

SELL CONTRACT

If SELL, EnergyCalc evaluates the REVENUE of SELLING the Hourly Demand at Contract Price for the entire contract duration.

Definition:

  1. Revenue:

    • At Selling Price – Revenue gained from selling the Hourly Demand at the Contract Price

    • At Spot Price (Average) – Revenue from selling the Hourly Demand to the WESM at the most probable spot price

    • At Spot Price (95th) – High-side Revenue from selling the Hourly Demand to the WESM. It means revenue from selling to WESM has a 5% probability to be equal or higher this amount

    • At Spot Price (5th) – Downside Revenue from selling the Hourly Demand to the WESM. It means revenue from selling to WESM has a 5% probability to be equal or lower this amount

  2. Additional/Loss Revenue of Contracting:

    • Versus Spot Price (Average) – positive value means selling the Hourly Demand at Contract Price is more profitable than selling to WESM. 

    • Versus Spot Price (95th) - positive value means selling the Hourly Demand at Contract price has a 95% probability of profitability 

    • Versus Spot Price (5th) - negative value means selling the Hourly Demand to the WESM is more profitable than selling at the Contract Price 

BUY CONTRACT

If BUY, the EnergyCalc Evaluates the COST of BUYING the Hourly Demand at Contract Price  for the entire contract duration:

Definition:

  1. Cost:

    • At Buying Price – Cost of Buying the Hourly Demand at the Contract Price

    • At Spot Price (Average) – Cost of Buying the Hourly Demand from the WESM at average spot price

    • At Spot Price (95th) – High-side Cost of buying the Hourly Demand from the WESM. There is a 95% probability the Cost may get lower than this amount  

    • At Spot Price (5th) – Downside Cost of buying the Hourly Demand from the WESM.  There is a 95% probability the Cost may get higher than this amount

  2. Addt’l Savings/Cost of Buying from Spot Market:

    • Versus Spot Price (Average) – positive value means, at the average, buying from WESM is more profitable than buying at Contract Price

    • Versus Spot Price (95th) -  positive value means buying at Contract Price is way costlier than buying from WESM

    • Versus Spot Price (5th) - negative value means buying at Contract Price is more profitable than Buying from WESM
