What distinguishes a 'green tariff' program offered by a utility from a standard Renewable Energy Certificate purchase?
Answer: Green tariffs provide utility-administered renewable electricity supply paired with RECs under a regulated rate structure
Green tariffs are utility-offered programs that bundle renewable energy supply and RECs under a regulated rate, simplifying renewable procurement for commercial customers.
An energy manager calculates a simple payback period of 4 years for a $200,000 efficiency project. What annual savings does this project generate?
Answer: $50,000
Simple payback = Investment ÷ Annual Savings; $200,000 ÷ 4 years = $50,000 annual savings.
What is the primary purpose of an Energy Performance Contract (EPC) with an Energy Service Company (ESCO)?
Answer: The ESCO finances and implements efficiency improvements, with repayment guaranteed from the resulting energy savings
In an EPC, the ESCO guarantees that efficiency improvements will generate enough savings to cover the project investment and its financing.
Which building rating system is most specifically focused on energy performance and commonly used for commercial real estate benchmarking in the US?
Answer: ENERGY STAR Portfolio Manager
EPA's ENERGY STAR Portfolio Manager is the primary US benchmarking tool for commercial building energy performance, generating a 1-100 score.
A company wants to demonstrate '24/7 carbon-free energy' matching. What does this commitment require beyond standard annual REC matching?
Answer: Matching renewable energy consumption hour-by-hour in the same grid region where electricity is consumed
24/7 CFE requires temporal and locational matching of renewable generation to consumption every hour, not just annual aggregation.
Which demand response program type compensates customers for reducing load when called upon by the grid operator during high-demand events?
Answer: Interruptible load programs
Interruptible load programs pay customers a capacity or curtailment payment in exchange for committing to reduce load when the grid operator issues a curtailment event.
When evaluating the environmental attributes of a Power Purchase Agreement (PPA), which factor most directly determines the 'deliverability' of the renewable energy?
Answer: Whether the project is in the same or an electrically connected grid region as the buyer's load
Deliverability depends on the renewable generator being within the same grid region or having a transmission path that allows the power to reach the buyer's location.
