Solar Hedging Power Generation

What is a hedge ratio if a buyer sells 300 MWh?

buyer sells 300 MWh in a forward contract, this would correspond to a hedge ratio of 0.3. Using this definition, suppose a buyer of a baseload PPA decides to hedge his settlement amounts in a particular month by selling a swap at a price for some ratio of his guaranteed hourly generation quantity.

What is the optimal hedge ratio for a P50 hourly shaped PPA?

The optimal hedge ratio for each P50 hourly shaped PPA is the value that corresponds to the lowest point on the blue curve in each of the plots. Interestingly, the optimal hedge quantity is actually greater than one for the solar PPA. This means that the optimal hedge is to sell more than the monthly guaranteed generation under the contract.

Are long-term wind and solar energy generation forecasts suitable for PPAs?

We propose a long-term wind and solar energy generation forecasts suitable for PPAs with cost optimisation in energy generation scenarios. We use Markov Chain Monte Carlo simulations with suitable models of wind and solar generation and optimise long-term energy contracts with purchase of renewable energy. 1. Introduction

Is solar energy a viable option for energy-demanding industries?

With development of more efficient solar power technologies, this type of renewable energy supply becomes a viable option, economically and environmentally, for development of energy-demanding industries, such as crypto-currency mining (Nikzad and Mehregan, 2022) and field irrigation ( Nikzad et al., 2019).

Are PPAs a hedging tool?

PPAs are seen as a hedging tool by many organisations, as they offer an opportunity for energy buyers to achieve price certainty beyond 3–5 years, and at the same time meet their sustainability objectives. Mature renewable technologies were price-competitive in 2020 and could offer prices for their intermittent output at all-time lows.

Does residual energy contribute to a seller's position in a shaped PPA?

The amount of residual (or deficit) energy between the contracted shape and the realized generation volume contributes risk to the seller’s position in a shaped PPA and should be valued within this context.
