Open Market Plan
Direct exposure to the wholesale market for customers who can manage the volatility.
How it works
Open Market passes the wholesale market clearing price through to the customer with an agreed retail adder. Where the customer prefers, the supply contract can include caps, collars, or partial hedges to bound the downside. The plan provides the most direct exposure to market dynamics among Rockport’s offerings.
When it’s the right fit
Best for organisations with procurement teams that already monitor wholesale electricity markets, or operations that can shift load to align with price signals. It is the highest-risk, highest-potential-reward plan structure on our menu.
Best for
- Sophisticated procurement teams
- Customers with operational load flexibility
- Buyers comfortable with monthly variance in unit cost
Frequently asked questions
What is the Open Market Plan?
The Open Market Plan passes the Wholesale Electricity Spot Market (WESM) clearing price through to your invoice with an agreed retail adder. It is Rockport Power’s most direct market exposure: unit costs move with the market, downward as well as upward, from month to month.
Who should consider WESM-indexed pricing?
Organisations with procurement teams that already monitor wholesale electricity markets, and operations that can shift load in response to price signals. It is the highest-risk, highest-potential-reward structure on Rockport Power’s menu, so it suits buyers comfortable with monthly variance in unit cost.
Can I limit my exposure under Open Market?
Yes. The supply contract can include caps, collars, or partial hedges that bound the downside while retaining most of the market upside. Rockport Power structures these protections to your risk appetite, and settlement remains monthly with interval-level transparency into how prices flowed through.
What is WESM?
The Wholesale Electricity Spot Market is the centralised venue where generators and suppliers in the Philippines trade electricity, with prices clearing at regular intervals based on supply and demand. Under the Open Market Plan, those clearing prices form the basis of your monthly supply charge.
How long is an Open Market contract?
Typical terms run twelve months with evergreen renewal, so the arrangement continues unless either party gives notice. Settlement is monthly, with interval-level transparency showing how each period’s WESM prices translated into your invoice — useful for teams actively managing consumption against the market.
