The rates don’t apply to a residence used for commercial, professional or business activities. But if the domestic use can be separately metered from the business activities, then these rates would apply to the domestic part.
We consider a single-family dwelling one in which four sleeping rooms or more are rented or are available for rent as non-domestic, and the applicable general service rate applies.
Black Hills Colorado Electric files Advice Letter No. 817 to Amend the Energy Payment Rate Effective Jan. 1, 2022
On November 30, 2021, the company filed an advice letter with revised tariff to amend the Energy Payment Rate (Avoided Cost Rate or Average Hourly Incremental Cost of Electricity) in the company’s Colorado P.U.C. No. 11 Tariff for Co-generation and Small Power Production Facilities. The proposed effective date is January 1, 2022. The revised tariff will increase the Energy Payment rate by 31.6% from $0.02757/kWh to $0.03326/kWh.
This tariff affects any customers serviced under the Co-generation and Small Power Production rate. The company currently has no customers serviced under this rate.
Some customers served under the Company’s net metering service are affected by the rate amendment. Net metering customers can elect to receive payment at this filed rate at the end of the calendar year for any excess generation produced from their systems that is above the amount of their energy consumption. They can also choose to roll any excess kWh over as a usage bill credit to the next calendar year rather than take the cash payment. The amendment increases the payment that Black Hills makes to net metering customers for excess energy produced from a customer’s energy production system.

Black Hills Energy filed its annual Transmission Cost Adjustment (“TCA”)
What you need to know about the annual Transmission Cost Adjustment (TCA)
On November 1, 2021, Black Hills Energy filed its annual Transmission Cost Adjustment (“TCA”). The TCA is a monthly surcharge on all customers’ bills to pay for the costs of maintaining and improving the high-voltage transmission system that ensures the safe, reliable delivery of energy across our southern Colorado service territory.
The TCA is updated on an annual basis to allow Black Hills to recover construction costs incurred the previous year for projects related to our transmission towers and structures, high-voltage transmission lines, and substations – critical infrastructure necessary for carrying high-voltage electricity quickly and efficiently to the lower voltage distribution system that serves homes and businesses.
The 2022 TCA rate will be $0.005072 per kilowatt-hour (kWh). Based on this rate, the average residential customer monthly bill would see an increase of 89 cents, going from $104.78 per month to $105.67 per month. The average small commercial customer monthly bill would see an increase of $3.42, from $341.48 per month to $344.90 per month. The 2022 TCA rate will be in effect from Jan. 1, 2022 through Dec. 31, 2022.
Energy cost adjustment (ECA) adjusts on July 1, 2022
Black Hills Energy has filed to adjust its ECA rate on July 1, 2022, pending approval by the Colorado Public Utilities Commission in Proceeding No. 22AL-0234E. The new rate will increase to $0.06088 per kWh, passing along $19M of additional costs incurred by the company. The current rate is $0.05101 per kWh. The new rate will increase a typical residential bill by $6.21, or 5.52%, and increase a typical small commercial bill by $10.47, or 2.76%.

ReadyEV
On May 8, 2020, we filed an application at the Colorado Public Utilities Commission for the approval of our first Transportation Electrification Plan, or TEP. This was our first TEP required by Colorado Senate Bill 19-077, and if approved, will be effective for three years until the end of 2024.
We designed our TEP to encourage transportation electrification while minimizing costs and giving our customers the power to shape what the electric vehicle industry in southern Colorado. The TEP consists of 4 major parts: 1) customer education and outreach, 2) rebates on EV charging equipment, 3) new rates for EV charging, and 4) classifying EV charging equipment as permanent load for the purposes of line extensions. To avoid customer confusion with a new line on customer bills, we have proposed to streamline the cost-recovery of the TEP by combining it with our Demand Side Management Cost Adjustment. We estimate that an average residential customer will see their monthly bill increase approximately 0.24%, or $0.19 in 2022, $0.21 in 2023, and $0.24 in 2024. We estimate that an average Small General Service customer will see their monthly bill increase 0.24%, or $0.71 in 2022, $0.77 in 2023, and $0.87 in 2024.

Black Hills Colorado Electric files Advice Letter No, 815 to Amend the PCCA Rates Effective Jan. 1, 2022
On November 15, 2021, Black Hills Colorado Electric filed Advice Letter No. 815 at the Colorado Public Utilities Commission.
The principal purpose of this annual filing is to amend the Company’s PCCA tariff sheets to reflect the incremental purchased capacity-related costs. The PCCA recovers the incremental cost of purchased capacity above the level of purchased capacity costs included in base rates. This PCCA filing represents the incremental purchased capacity costs for the period January 1, 2016 through December 31, 2021. The proposed PCCA rate is $0.00145/kWh for Residential and Energy Only Customers, $0.00130/kWh for Small General Service customers, $0.36983/kW for Large General Service customers, and $0.44670/kW for Large Power Service customers.
If permitted to go into effect on January 1, 2021, the tariff revisions will result in increased annualized revenues of approximately $460,792, as compared to the 2021 PCCA rates that are currently in effect. Based on the proposed PCCA rates, the average residential customer monthly bill, under Rate Schedule RS-1 with an average usage of 600 kWh per month, will increase $0.23, from $104.78 to $105.01, or 0.22%. The average small commercial customer monthly bill, under Rate Schedule SGS-N with an average usage of 2,300 kWh per month, will increase $0.72, from $341.48 to $342.21, or 0.21%.
