Pennsylvania businesses have been focused on PECO's 15% rate increase this month, but a separate change is taking effect on July 1 that's gotten less attention. PPL Electric Utilities is implementing a new large load tariff for commercial customers with demand of 50 MW or more at a single facility, or 75 MW or more in aggregate across facilities within a 10-mile radius.
If your business operates in central or eastern Pennsylvania and you're in that range, here's what you need to know before the calendar flips.
Approved as part of PPL's rate case settlement, the tariff creates a distinct rate structure for high-demand commercial and industrial customers. Large load service agreements carry an initial term of not less than 10 years and include minimum load guarantees and exit fees. Additionally, each customer is required to have an agreement stating its interconnection and provide proof of funds in an amount equal to the cost of upgrades.
PPL Electric's proposed tariff would have large loads contribute $11 million annually to the company's residential low-income program. The settlement notes it doesn't resolve every outstanding issue, and tariff terms may shift based on the PUC's broader review of large load pricing.
Tariff structure changes aren't just about what you pay today. They affect how suppliers price competitive supply contracts, how your load is measured for capacity obligation purposes and what products make sense for your facility going forward.
A change of this kind can shift the economics of fixed vs. index pricing, alter how demand charges are calculated during peak hours, and affect your exposure to capacity costs.
If you are a large energy user such as manufacturers, distribution centers, data centers, hospitals, universities and multi-site commercial portfolios with aggregated load in PPL service territory, you should audit your strategy.
Before July 1 you should do the following:
This is exactly the kind of change that gets missed until it shows up on a bill three months later. Getting ahead of it now costs nothing. Getting caught off guard can cost significantly more.
