State Government Summary List All

The state does not offer financial incentives for energy efficiency. South Dakota is one of the few states to require residential energy use disclosure. The state government leads by example by requiring the benchmarking of energy use in public buildings. There are no major research centers focused on energy efficiency in the state.

Financial Incentives List All

Financial Incentive information for South Dakota is provided by the Database of State Incentives for Renewables and Efficiency (DSIRE South Dakota).

Building Energy Disclosure List All
  • Building type(s) affected: residential

SB 64 established certain energy efficiency disclosure requirements for new residential buildings. This policy is triggered at the time of sale.

Public Building Requirements List All

In 2008, the South Dakota legislature passed a bill (SB 188) requiring use of high performance building standards for new state construction and renovation. The new standard must be at least as stringent as the LEED-Silver standard, the two-globe standard on the Green Globes rating system, or a comparable standard. There is no specific energy efficiency requirement in the building standard. The state standard applies to all new state-funded construction projects costing more than $500,000 or occupying more than 5,000 square feet of space. 

The State of South Dakota Energy Conservation Loan Fund uses over $8 million dollars of funds to provide no-interest loans to State Government of South Dakota projects. The loan repayment is based on energy costs savings. 

South Dakota tracks and benchmarks building energy use with Energy Cap.

Fleets List All

While South Dakota utilizes flex fuel vehicles and promotes the use of ethanol blends in fleet vehicles, the state does not have a statewide energy-efficient fleet requirement. 

Note: For state efficient fleet initiatives, policies listed must make a specific, mandatory requirement for increasing state fleet efficiency. State alternative-fuel vehicle procurement requirements that give a voluntary option to count efficient vehicles are thus not included.

Energy Savings Performance Contracting List All

South Dakota enables ESPCs throughout the state and is currently conducting a study through the Department of Transportation to identify which state facilities provide opportunities for energy savings. The Board of Regents is investigating the usage of ESPC for improvements at the higher education campuses. In 2016 the Governor signed House Bill 1032 to revise certain provisions regarding guaranteed energy savings contracts, clarifying the procurement process for EPCs.

There is no mandatory statewide energy code, but the 2009 IECC is a voluntary residential standard. Local jurisdictions may opt out of the state's commercial code. South Dakota completed a gap analysis in 2011.

Residential Codes List All

South Dakota has no mandatory statewide energy codes for residential construction. Codes are adopted by jurisdiction voluntarily. As of July 2011, state law established the 2009 IECC as a voluntary residential standard. Local jurisdictions also have authority to adopt various residential building and energy codes, including IRC and IECC.

Last Updated: July 2016

Commercial Code List All

South Dakota has no mandatory statewide energy codes for commercial construction. Codes are adopted by jurisdiction voluntarily. For commercial construction, ASHRAE 90.1 or IECC compliance is required by reference in the 2012 IBC, which is the mandatory statewide commercial building standard in state law unless local jurisdictions have either opted out of it or specifically adopted another code.

CHP
Score: 0.5 out of 4
CHP Summary List All

The state has an interconnection standard that applies to CHP, but does not otherwise have policies in place that encourage CHP deployment. No new CHP systems were installed in South Dakota in 2015.

Interconnection StandardsList All

Policy: South Dakota Public Utilities Commission Rule 20:10:36

Description: The South Dakota Public Utilities Commission adopted its interconnection standards in May 2009. The standards, which apply to customers of investor-owned utilities, delineate four levels of interconnection for systems up to 10 MW in capacity. All interconnections use the IEEE 1547 standards, and South Dakota’s standards call for reasonable timeframes for application and approval. The requirement of external disconnect switches is authorized, limited interconnection to area networks is permitted, and general liability insurance is required

Utilities
Score: 2.5 out of 20
Utilities Summary List All

South Dakota’s utilities have been implementing ratepayer funded energy efficiency programs since the mid-2000s, however the levels of efficiency program spending and associated energy savings have been lower than the national average and have not increased significantly. Only one utility does not currently have a program in place but it is currently requesting permission from the Commission to do so. In addition, South Dakota instituted an electric utility performance incentive program. In 2010 the South Dakota Public Utilities Commission authorized a lost revenue adjustment mechanism for Northwestern Energy for both gas and electric efficiency programs. 

The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Customer Energy Efficiency Programs List All

South Dakota's utilities run limited energy efficiency programs. Several utilities offer commercial and residential rebate programs, and Otter Tail Power also runs a financing program for commercial and residential customers.

The South Dakota Energy Smart Initiative brings together utility partners to pledge their support of improving energy efficiency in South Dakota. Partners include both investor-owned and publicly owned utilities, which report numerous plans and new efforts to offer energy efficiency programs and services to their customers. 

The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Energy Efficiency as a Resource List All

Utilities in South Dakota are vertically integrated and generally adhere to traditional ratemaking principles. All utilities perform integrated resource planning (IRP), which considers energy efficiency as a potential resource to meet demands.

There is currently no EERS in place.

Utilities may voluntarily participate in the state's Renewable, Recycled, and Conserved Energy Objective (ARSD 20:10:38). Energy efficiency counts toward this objective.

Utility Business Model List All

All investor-owned utilities in South Dakota recover lost revenues. In 2010 the South Dakota Public Utilities Commission authorized a the first lost revenue adjustment mechanism  for Montana-Dakota Utilities in docket NG09-001. Lost revenues are negotiated as a percentage of approved budget spend. Any over/under collection for the first year (including interest), plus forecasted DSM program costs and lost revenues for the second year are added together to compute rates for the second year.

South Dakota has approved performance incentives through various mechanisms. In 2008, OtterTail Power received approval for its energy efficiency programs, with a flat-rate bonus if the utility met its efficiency goals. In 2009, the Commission approved a similar mechanism for MidAmerican Energy. In 2010, MidAmerican’s incentive was amended to a straight return based on a percentage of the program budget. Montana-Dakota UtilitiesNorthwestern Energy, Black Hills Power, Xcel Energy and Otter Tail Power have similar mechanisms. The fixed percentage, as settled upon between the utility and the Commission, is intended to cover lost revenues due to EE programs.

Evaluation, Measurement, & Verification List All
  • Cost-effectiveness test(s) used: TRC, RIM
  • Uses a deemed savings database: no

The evaluation of ratepayer-funded energy efficiency programs in South Dakota relies on both regulatory orders and legislative mandates. Evaluations are mainly administered by the utilities. There are no specific legal requirements for these evaluations in South Dakota. South Dakota uses two of the five classic benefit-cost tests identified in the California Standard Practice Manual. These are the Total Resource Cost (TRC) and Ratepayer Impact Measure (RIM) test. South Dakota specifies the TRC to be its primary test for decision making. The benefit-cost tests are required for total program, customer project, and individual measure level screening, with some exceptions for low-income programs, pilots, and new technologies. No rules for benefit-cost tests are specified.
