Making this project happen –Thank You!

• Department of Energy Office of Electricity & Sandia National Laboratories is providing technical guidance and funding ($250,000)

• Iowa Economic Development Authority is providing funding ($200,000)

• Iowa State University is a research partner

• City of Decorah / Parks Department is providing leased space for the project

Why Decorah?

• Northeastern Iowa community with an abundance of wind and solar distributed generation (DG)

• Over 3 MW of customer-owned DG installed on targeted circuit with a normal peak load between 2.5 and 3 MW (inclusive of DG production)

• Our staff saw that the hosting capacitywould soon be depleted. Rather than restrict future DG or rebuild the circuit, this is a customer-focused solution that meets this challenge and may lower customer costs.

Hosting Capacity and DG

• Process for a customer installing DG begins with an “Interconnect Application”

• Our staff look at the proposed DG system and the circuit it feeds to determine if any upgrades are needed to maintain quality and safety on the circuit

• If upgrades are needed, the customer is presented with options on how to get their DG approved (options can include limiting size of DG, or paying for upgrades)

7

Can we solve it differently with a battery?

• Instead of being reactive and sticking with traditional line upgrades – or limiting customer installations – what alternatives could we try?

• How can we proactively improve hosting capacity and pave the way for more renewable DG?

• What are the capabilities that need to be engineered into the system to make it all work?

• How do our local Decorah crews support the system once it is installed?

8

Decorah Battery System Design•Traditional Line and Substation Upgrades to improve

hosting capacity could range from $1M to $10M,

depending on where DG is proposed in the future

•At about $2.5M, we predict the Decorah Battery

Project will prove to allow more DG to be added for a

lower total cost.

➢There are some hosting capacity issues that simply

cannot be solved by traditional line upgrades

Decorah Battery System Design•2.5 MW, 2.9 MWH system

•Larger power rating → more flexibility

‒Voltage managed with reactive power (Vars)

‒Power Flows managed with real power (Watts)

•Samsung / Sungrow Integrated Solution from EnelX

‒ Lithium Ion (NMC Chemistry)

Power (flow rate) Energy (size of tank)

2.9 MWH ÷ 2.5 MW

= 1.16 HRS

Duration

Decorah Battery System Operation

•To Increase Hosting Capacity and maximize the benefit

of DG, the battery will manage voltage and real power

flows on the circuit

• In Future Phases, we will explore other use cases and

revenue streams for the battery

Alliant-ISU collaboration: voltage stability• ISU has major research effort led by Professor V. Ajjarapu, on sensor-

based analytics for power systems.

• Decorah is valuable example to help develop better models to predict short term and long term voltage stability, with increasing DER integration and storage integration.

• Alliant is providing feeder models to support ISU’s research: the Decorah distribution system, with significant DER and storage, provides a new opportunity to test our models using operating data.

• µpmu data will be used to validate ISU’s data-driven control methods

7

Alliant-ISU collaboration: battery health

• ISU team led by Professor Chao Hu is developing new techniques to predict battery degradation and life under different operating conditions (e.g. peak shaving, or frequency response).

• ISU is proposing to test these techniques using Alliant’s Decorah battery performance data

• Research currently proposed to the Iowa Energy Center will leverage the Decorah data into a larger framework of battery health monitoring, as well as development of machine-learning techniques to accelerate the evaluation of battery lifetime.

Energy infrastructure is transforming and Iowa is on the cutting edge of this transformation:

• Investments in wind, solar, biofuels, storage and transmission by EPRC industry partners

• ISU power group integral to this transformation, through teaching, research and industry outreach. The students we train are the future of this transformation.
