An alternate way to deal with shielding green power clients from energy cost changes is to substitute a particular green age Electricity Plans rate for the traditional energy age rate. Under this methodology, green power clients pay the entirety of similar charges as base rate clients, including transmission, dispersion, charging, and regulatory costs. In any case, rather than paying the standard age costs, they pay the expense of the renewable energy age and any supplemental expenses (auxiliary administrations and program execution costs.
Austin Energy has utilized this methodology in valuing its Greenhouse item, which is provided basically with wind energy. A critical trait of the Greenhouse item is the foundation of a different green charge, which substitutes straightforwardly for the utility’s fuel charge. The fuel charge is a detail on the client’s bill, comprising anticipated yearly fuel and bought power costs, and assessed expenses and charges from the Electric Reliability Council of Texas brought about to meet help region obligations.24 The green charge, then again, is controlled by the expense of the renewable energy power buy contracts Austin Energy signs to supply the program, in addition to extra expenses, for example, auxiliary administrations and item advertising, and is at present fixed for a very long time.
The key factor that permits Austin Energy to offer a fixed-rate green power item is that the renewable energy supply is secured at a proper rate for 10 to 20 years, contingent upon the related inventory contracts. In like manner, business clients, who are the essential objective of the program, should focus on the Greenhouse program for 15 years,25 diminishing the danger for the utility that interest for the renewable energy venture will vary. The utility additionally has an unbundled rate structure, permitting the green charge to straightforwardly fill in for the fuel charge on client bills. At the point when Greenhouse was dispatched in 2000, Austin Energy went into an agreement for 40 MW of wind energy to supply the program. From that point forward, the utility has extended the program multiple times, each time going into an agreement for extra renewable energy creating a limit concerning the program. With each new agreement (“cluster”) of renewable energy for the program, purchasers lock in the cost of the most recent bunch of age for as long as 15 years, contingent upon the term of the assets obtained.
An elective methodology is to absolve green power clients from petroleum product cost changes. Be that as it may, because FCA’s are a broken measure for tending to fuel-cost changes between rate cases, this methodology possibly gives longer-term fuel-value security if appropriately organized. For the time being, the FCA(Fuel Cost Adjustments) exception gives a steady value advantage to green power clients, yet the advantage is nullified if higher fuel costs become inserted in base rates without a practically identical descending change of the green power premium.
At last, utilities can return to the green power value premium when critical fuel value changes happen or when base rates are changed, and consider whether the green power premium ought to likewise be changed, therefore. This is the most well-known methodology utilized by utilities throughout the long term. What’s more, there is an open inquiry in regard to whether green power clients ought to likewise be excluded from rate changes coming about because of utility uses to lessen air emanations from petroleum product burning or state renewable portfolio standard prerequisites.
