Public Building Requirements List All
New construction shall, in good faith, be designed with the intention of meeting or exceeding the high-performance green building standard that was in effect when the construction was registered with the rating system. Before construction begins, the Office of the State Engineer, architect, and building owner shall identify, in good faith, all components of the new construction.
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 $1,000,000 or occupying more than 10,000 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.
South Dakota no longer requires a specific level of LEED or Green Globes rating, although LEED Silver or a Green Globes - 2 Globe rating are still the goal. The Office of the State Engineer reviews and approves projects to strive to meet these goals, without adding significant cost to chase ineffiecent points. This only applies to state government buildings.

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, however most jurisdictions have adopted codes based on the 2015 IECC. Local jurisdictions also have authority to adopt various residential building and energy codes, including IRC and IECC.

Commercial Code List All
South Dakota has no mandatory statewide energy codes for commercial construction, however most jurisdictions have adopted codes based on the 2015 IECC. 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
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 2018.
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 out of 29
Utilities Summary List All
South Dakota’s regulated investor-owned utilities have been implementing ratepayer-funded energy efficiency programs since the mid-2000s, but the levels of efficiency program spending and associated energy savings have been lower than the national average and have not increased significantly. These programs do include a lost revenue adjustment mechanism that is calculated as a certain percentage of actual energy efficiency spending or approved energy efficiency program budgets, whichever is lesser. Many non-regulated utilities (e.g. municipals and cooperatives) in South Dakota also have energy 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.

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.

Utility Business Model List All
All investor-owned utilities in South Dakota recover lost revenues. In 2010, the South Dakota Public Utilities Commission authorized 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 Utilities, Northwestern 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
- Primary cost-effectiveness test(s) used: total resource cost test
- Secondary cost-effectiveness test(s) used: ratepayer impact measure test, utility cost test, participant cost test, societal cost test
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.
According to the Database of State Efficiency Screening Practices (DSESP), South Dakota specifies a Total Resource Cost model (TRC) as its primary cost effectiveness test for decision making. In addition, South Dakota uses the Ratepayer Impact Measure test (RIM), the Utility Cost Test (UCT), the Participant Cost Test (PCT) and the Societal Cost Test (SCT) as secondary tests. The benefit-cost tests are required for total program, customer projects, and individual measure level screenings, with some exceptions for low-income programs, pilots, and new technologies. No rules for benefit-cost tests are specified.
Further information on cost-effectiveness screening practices for South Dakota is available in the Database of State Efficiency Screening Practices (DSESP), a resource of the National Efficiency Screening Project (NESP).
