Capital Electric Bismarck, ND Central Power Electric Cooperative is a wholesale power supply and transmission cooperative organized in 1949 to generate power for its member rural electric distribution cooperatives. Ordean (Lars) Nygren – Manager Dwight Wrangham – President Rodney Eckroth Sheri Haugen-Hoffart Kyle Hilken Kyle Hilken Director Central Power today continues to supply the bulk power needs of its members through a backbone system of transmission and subtransmission facilities. The six member cooperatives that make up Central Power combine to serve over 65,281 farms, homes and businesses located in a service area of 25 counties across the central and southeastern third of North Dakota. Dakota Valley Electric Milnor, ND Bruce Garber – Manager Richard Schlosser – President Connie Bitz Arden Fuher John Hauschild Central Power’s facilities required to serve the members include 167 delivery points, 25 wholly owned and 10 jointly owned high-voltage transmission stations, and 1,381 miles of transmission line interconnected with the Western Area Power Administration, Basin Electric Power Cooperative, and three investor-owned utilities. In all, Central Power has a $248.5 million investment in utility plant 2 Central Power Electric Cooperative, Inc. Josh Kramer David Liuska Arlene Olson Bill Patrie Deon Vilhauer Arden Fuher 2015 Annual Report Richard Johnson Blaine Lundgren David Paulson Kim Rasmussen Matt Thompson Director 3 Message from the President To say that 2015 was a good year for Central Power Electric Cooperative would be an understatement. Indeed, 2015 was a very remarkable year at your G&T and a year filled with significant achievements in which we can all feel a major sense of pride Mark Brehm and accomplishment. President This success did not come about by happenstance and luck; rather, it was the culmination of considerable strategic thinking, foresight, critical decisions, and hard work. As a board, we have a responsibility to provide the necessary policy direction and budgetary approvals for the cooperative and then turn our management team loose to carry out our objectives. This is rather easy to do when you have complete confidence in your staff and it is easy to have this confidence when they have a record of delivering. We have what I would consider to be one of the finest management teams in the industry and rest assured they have laser-like focus on delivering value to the members. Your G&T’s Board of Directors could not be more pleased with their dedication and motivation to do just that. A purported ancient Chinese curse reads “May you live in interesting times” and clearly we are operating in “interesting times” in the electric utility industry. It would be fair to say the intended characterization of “interesting times” is indeed “challenging times” and these times demand a lot of commitment, effort, and vision from our organizations’ leaders and employees. I for one feel strongly we can rest assured that we have the resources to not only respond to the challenges, but also to be proactive in addressing them and seeking out, creating, and capitalizing on opportunities; in a way, “Charting a Course for a Powerful Future”! 4 What is challenging in today’s utility environment? Just about every aspect that comes to mind; government regulations and compliance requirements, including environmental issues like the Clean Power Plan, Waters of the US, the recent Federal Coal Lease Moratorium, Regional Haze, Coal Combustion Residuals (Ash), Cross-State Air Pollution, Endangered Species Act and the seemingly endless march of reliability compliance requirements under the North American Reliability Corporation, NERC, and Midwest Reliability Organization, MRO; permitting; right-of-way and site acquisition; rate pressures; and Regional Transmission Organization, RTO, integration and the Federal Energy Regulatory Commission, FERC, approval process to name a few. A prime example of “Charting a Course for a Powerful Future” would certainly include our vision turned into action to move toward having as much of an independent transmission system as we could plan, design, and construct in the past ten years to address system deficiencies, and in so doing, positioning ourselves extremely well for the future. Conjoined to the previous example of “Charting a Course for a Powerful Future”, it would have been possible for our management team to continue our significant discussions with Otter Tail Power to extend our Integrated Transmission Agreement, ITA, beyond its stated termination date of December 31st, 2015 and stay in our comfort zone with a familiar agreement that we have operated with for 43 years. But that would have been the easy course, which would have required significant compromise on Central Power’s part, and one which would not have moved us fully forward into the RTO environment or afforded us the opportunity to take advantage of many of the benefits associated with that transition. So we decided, after extensive deliberation, to join and integrate into Southwest Power Pool, SPP, as a Transmission Owner, TO, in the Upper Missouri Zone, UMZ, and to let the ITA expire under its own terms. Central Power Electric Cooperative, Inc. Last October we applied for membership in SPP with a request for several cooperative minded governance amendments and submitted our Annual Transmission Revenue Requirement, ATRR. We are also in the process of mutually cancelling most of our Basin IS Leases; and Basin is in the process of applying for facility credits on our behalf for our qualifying facilities in the Midcontinent Independent System Operator, MISO, RTO in the Otter Tail Power zone. On December 30th, 2015, our SPP ATRR was conditionally accepted by FERC with an effective date of January 1, 2016. Following is the language from the order in Docket ER16-209: 1. In this order, we accept Southwest Power Pool, Inc.’s (SPP) proposed revisions to its Open Access Transmission Tariff (Tariff ) to add a formula rate template and implementation protocols to accommodate the recovery of an annual transmission revenue requirement for SPP member Central Power Electric Cooperative, Inc. (Central Power), effective January 1, 2016, subject to refund, and establish hearing and settlement judge procedures. Our requested membership agreement amendments were accepted by FERC on February 8th, with an effective date of February 14th, as requested by SPP. This was the most significant foundational change Central Power has undergone since the ITA was formed in 1972 and it is a very positive step. However, we did not get to where we are alone. Basin Electric’s RTO team has been an incredible resource to us and we wish to sincerely thank them for all they have done to assist Central Power and the other Basin members with this entire proposition. We also recognized we would need outside legal and engineering assistance so we engaged the engineering firm Guernsey, Engineers, Architects, Consultants from Oklahoma City, OK; the legal firm of Schiff Hardin, LLP from Washington, DC, and GDS Associates, Inc. from Marietta, GA, bringing some of the best and brightest industry experts onboard to assist us getting this right and this is also part of “Charting a Course for a Powerful Future”. Basin is taking SPP and/or MISO transmission tariff service for service to our loads. The MISO transmission tariff service costs to serve Central Power’s load is substantial but under Basin’s Transmission Policy approved by their board in July of 2014, the impact to Central Power is substantially reduced. Under this policy change, all but the WAPA portion of the MISO transmission costs are borne by Basin, which leaves us to pay an estimated $750k annually. This policy change was the result of a very concerted effort on Central Power’s part to bring comparability to the Basin membership and to put Basin in a place to properly evaluate which RTO to join, and what resources to build and where, by having all the relevant cost considerations as their responsibility. This was the single biggest policy change in the history of Basin Electric and is a shining example of what can be accomplished by “Charting a Course for a Powerful Future!” 2015 Annual Report 5 Report from the General Manager This policy change moved Basin to providing comparable transmission service to all of its members regardless of direct physical access to the Basin/WAPA Integrated System and will save Central Power and its members millions of dollars annually. We were also confronted with a very serious issue with the portion of our WAPA hydropower allocation that is delivered to our loads in the MISO footprint. MISO’s rules and procedures did not appropriately recognize our monthly peak demand allocation and the unrecognized demand would have had to be made up by Basin at their Class A demand rate. This represented over a million dollar a year impact to Central Power. We worked alongside Basin and other similarly affected Basin members to come up with a fix. Ultimately, Basin senior staff came up with a very good compromise solution that was palatable to WAPA and we cannot thank Basin enough for developing this solution. The compromise is not as good as the solution put forward by Central of redirecting our WAPA allocation to our deliveries in only the SPP footprint which would have helped Central avoid the estimated $750,000 per year in MISO transmission tariff expense. We were pleased to be able to reciprocate some of Basin’s assistance in these RTO matters and we like to think we helped with some level of assistance to SPP, Basin, and WAPA in dealing with their SPP Integration with regards to their October 1, 2015 integration and Otter Tail’s intervention and protest. Why all of this explanation of “Charting a Course for a Powerful Future” you may ask. Well, all of these actions allowed us to dampen the Basin’s roughly 7.8% rate increase for 2016 to a much more modest 2.65% from Central to its members. That is a very big deal when one considers that Basin represents about 81% of our total costs (Central Power’s cost of operation is roughly 10% so it takes a lot of reduction to effect that kind of dampening). At the end of 2015, we provided the first ever Central Power Bill Credit from operations of 6 $1.5M in addition to passing on the roughly $305k in Renewable Energy Credits from Basin that we budgeted to keep in 2015 in order to provide a lower mill rate and in addition to these bill credits, the Central Power board passed through Basin’s $2.642M Bill Credit. All told, Central Power bill credited the members $4.447M at the end of 2015 which should further assist the members mitigate the 2.65% increase - “Charting a Course for a Powerful Future”. Another example of “Charting a Course for a Powerful Future!” would certainly include extending our Wholesale Power Contract with Basin Electric from 2050 to 2075 and entering into a Scheduling Agreement & and a Power Services Agreement. This was done subsequent to Central Power’s members extending their All-Requirements Wholesale Power Contracts with Central Power until 2075 which we thank the members for executing so quickly and without ado. Many thanks to our engineers and craftsmen for all the tremendous amount of design and permitting and construction they completed in 2015. Some of this work was on an extremely fast track and our personnel didn’t miss a beat. Our staff is also heavily engaged in reliability compliance with the Midwest Reliability Organization, MRO, working hard to keep us in compliance and avoid any potentially significant financial penalties. The board is certainly pleased to report that our employees worked safely this past year in that they have driven 7,126,897 miles without a chargeable accident since January 24, 1996 and worked 88,568 hours without a lost time accident since September 6, 2013. This is a remarkable accomplishment. Today we have many challenges but with the continued dedicated service and efforts from our Board of Directors, our employees, our members, and our affiliated organizations, we will be able to continue “Charting a Course for Powerful Future!” Central Power Electric Cooperative, Inc. It is my pleasure to report on 2015’s operations at Central Power Electric Cooperative. While the challenges and issues we dealt with this past year were numerous and significant, I am very pleased to report that the state of Central Power Electric Cooperative is Tom Meland, P.E. strong and we continue General Manager to be intensely focused on “Charting a Course for a Power Future”! What motivates us to continue pressing for solutions to these new and significant challenges and issues? Our strong desire to assist our members in their efforts to provide safe, reliable electric service at the lowest practical cost to their member-owners. As we close the books on 2015, it is an appropriate time to pause, catch our breath, and reflect back on the past year. There should be no doubt that we were fully engaged in the second most significant transformation Central Power has undertaken in its vibrant history. As the President stated, the Integrated Transmission Agreement, ITA, we shared with Otter Tail Power since 1973 reached the end of its term at year’s end. While we have struggled at times with that relationship given our very different business models and priorities, it did assist us in keeping our transmission costs reasonable. However, the future of transmission arrangements was moving front and center with our power suppliers concluding their analysis of Southwest Power Pool, SPP, membership and integrating into SPP on October 1, 2015, at nearly the same time as our ITA was set to expire. Central Power was deeply involved with Basin and WAPA’s consideration of SPP membership and we take great satisfaction in our belief that we were the prime mover and most influential member at the Basin Managers Advisory Committee and at the Basin board level with regard to Basin passing what is the most significant policy change in Basin Electric’s history – its updated Transmission Service Policy. This past year Central Power’s average member mill rate (delivered at the substation low side) was 58.42 mills per kilowatt hour, not including the year-end bill credits the Central Power Board of Directors approved. The member average mill rate includes the members’ Central Power Base Rate (Blended Rate), Electric Heat Rate, and Interruptible Rate purchases. As the President mentioned, Central Power was facing a nearly 7.8% effective rate increase from Basin going into 2016 and given that Basin represents approximately 81% of our total cost of service, this was a formidable concern. However, Central Power was able to moderate that increase to our members down to approximately 2.65% by seizing opportunities afforded to us through our support of Basin and WAPA joining SPP and through lobbying Basin for the Transmission Service Policy change. It is also important to remember Central Power provided an extremely significant buffer to the members for 2016 in the form of $4.447 million in yearend bill credits. So how did we accomplish this dampening when our total power costs from 2015 to 2016 are budgeted to go from 50.25 to 53.78 mills per kilowatt-hour, or a 3.53 mill increase? Our internal cost of service, less other revenues including Basin IS Lease Payments, is projected to go down from 5.31 mills per kilowatt-hour to 3.96, or a 25% reduction. The 3.96 is the lowest level it has been in the 21 years that I have been at Central Power. Most remarkable is the fact that while our non-power cost of operations is projected to drop 25% on a mills per kilowatt-hour basis, our Total Utility Plant at the end of 2015 was up from 2014’s $226 million to nearly $250 million, or an 11% increase. Additionally, we are working to obtain appropriate credits for our facilities in the MISO OTP zone and should be able to take advantage of the opportunity to reduce our system losses, potentially saving an estimated $2 to $3 million annually in total. These 2015 Annual Report 7 savings were not budgeted for 2016 as there was some uncertainty associated with them. Also, we will avoid future ITA deficiency payments of approximately $200 thousand per year. There are some increased costs as well, primarily due to MISO transmission service costs on power supplied by WAPA to our load in MISO. Basin will serve as the Market Participant to handle the transactions required to serve our load in MISO, but they are not responsible for the charges applicable to the portion of our power supply that comes from WAPA. At one point, we were looking at additional annual costs as high as $2.5 million that would be incurred due to WAPA power delivered to our load in MISO but it now appears that we will avoid the bulk of this additional expense and our costs will probably be in the $750 thousand per year range. We did not budget the original amount of $2.5 million for 2016 as it appeared to be a reasonable offset to the unbudgeted positive amounts listed in the previous paragraph. 8 Central Power has moderated relatively significant rate increases all while making significant improvements to our system. Most remarkably and rewarding, after quite a few years of strategizing and negotiating and with the crucial help of U.S. Senator Hoeven, we completed and energized the 35 mile Bottineau – Dunning 115kV line with the final approval and completion of the one mile J. Clark Salyer National Wildlife Refuge Crossing this past year. This was critical to placing this important reliability enhancing facility into service and to have it qualify under our SPP Annual Transmission Revenue Requirement, ATRR, so as to achieve cost recovery for it. substation and we expect to take delivery of this new mobile around the time of our 2016 Annual Meeting. More recently the Board approved writing a specification and requesting proposals to provide a replacement for our existing 5MVA mobile substation with a 69x60x43.8-25x12.5kV, 10MVA unit. We expect to present proposal information to the Board during the first half of 2016 in order to provide the Board with information necessary for them to determine if we should replace our existing 1968 unit. The Board is also considering a new storage building at our Minot yard to store the new mobile substation as well as other equipment. We have worked extensively this past year reinforcing our system in the Dunning (Westhope) area as outlined in detail in the Engineering and Operations Department report later in this report booklet. The Dunning projects also included an in-line 60kV power circuit breaker which allowed us to bring these facilities on-line in a closed loop method of operation which will improve reliability and allow us to put these 60kV facilities into our SPP ATRR as well. In 2015 we recognized the need for our three breaker 115kV Towner switching station, built in the early 1960’s, to be completely rebuilt. We looked to turn the rebuilding and future ownership of this station over to WAPA as it makes more sense in the RTO environment and they will begin construction of the new station in 2017. This past year we also completed work to operate our newer 69kV lines between Bottineau SE and Thorne as well as between Thorne and Rolla in a closed loop configuration with the addition of in-line power circuit breakers, which also improve reliability. We also made system modifications on our Rugby area facilities that will have the effect of moving more of our load into the SPP Balancing Area and Energy Market. Our engineers and craftsman made extensive improvements in the Capital Electric area including establishing distribution substation low-side metering to meter Capital at the same point we meter all the other members’ loads, rather than relying on upstream metering and contractual loss factors as we have done the last two years. We also initiated and completed thorough transmission studies of the Bismarck and Minot areas which identified several needed projects. I would also note that we met Basin’s Load Monitoring Incentive Credit requirements in all 12 months of 2015 and received $152 thousand in credits from them. In fact, we have received approximately $1.3 million in these credits dating back to 2003. Basin recognizes the value of this information and they are increasing the credit from 7 cents per MWh to 10 cents for 2016 so our credits should increase. Central Power also provides incentive credits to our members that perform this function and has issued $2.4 million in Load Monitoring Credits to those members since 2004. Our staff was hard at work this past year with Midwest Reliability Organization reliability compliance requirements. We continue adding new facilities and the standards are continuously updated which creates a challenge in keeping our programs and procedures up to date. In closing, I would like to take this opportunity to recognize several long serving managers for their notable careers in light of their upcoming retirements. Bruce Carlson, General Manager of Verendrye Electric Cooperative, having worked there for 33 years, with 7 years at Sheyenne Valley EC in between; Lars Nygren, General Manager of Capital Electric Cooperative, having worked there for 32 years after his initial 8 years at Verendrye; and Central Power’s long-time friend and supporter Dennis Hill, Executive V.P. & GM of the NDAREC, is retiring with 35 years at Statewide. Thank you gentlemen for your dedicated service. Your wise counsel will be missed. We are pleased to see that our two member cooperatives have selected their replacement managers and that the new managers are experienced individuals with whom we already have experience and relationships. Congratulations to Paul Fitterer, new General Manager at Capital Electric, and Randy Hauck, new General Manager at Verendrye Electric. They will do a great job in their new positions. We have an extremely busy year ahead getting into full swing with SPP operations and with completing the project load we have lined up. With steadfast direction and support from the Central Power Board of Directors, input from the Managers Advisory Committee, and outstanding employee effort, we will continue “Charting a Course for a Powerful Future”! I also want to thank Basin Electric and the Western Area Power Administration for our excellent working relationship and for their major role and significant participation in working together “Charting a Course for a Powerful Future”.

Central Power’s WAPA/Basin resource mix is 10/90 without the Minot Air Force Base’s WAPA allocation and respective load. Member Energy Purchases Member energy purchases of 2,418.9 GWH in 2015 demonstrated a 3.0 % decrease from 2014. Central Power’s peak Mick Kossan, C.P.A. demand for 2015 was set Manager of Accounting & Finance in January at 463.7 MW. This is the second highest peak recorded over the past two years of having six fully consolidated members, trailing only the 477.6 MW realized in January of 2014. Looking ahead to 2016, Central Power’s peak in January was 438.2 MW, well below both 2014 & 2015. In 2015, Central Power paid an average power supply cost of 50.46 mills per kWh, up from 49.46 mills per kWh in 2014, an increase of 2.0%. Rates In 2015, Central Power on behalf of its members spent Western Area Power Administration The 13 percent federal hydropower resource is secured through a firm Contract Rate of Delivery (CROD) contract with WAPA. The conditions from 2011 where the main-stem reservoir system was at unprecedented levels above the Corps of Engineers preferred storage levels has declined in the years following, but capacity remains close to average. Because of this, WAPA has not made any modifications to the 2010 rate for the years 2011-2015. While the composite rate on a mills per kWh basis remains the same for 2015 at 33.25 mills, the $125,881,214 on wholesale power purchases. This amounts to over 88 percent of Central Power’s annual operating expense. Adding in Central Power’s cost of operation, including $190,666 in wheeling payments to Otter Tail Power for use of their transmission facilities and accounting for system losses, Central Power’s members paid an all-inclusive average of 57.80 mills per kWh in 2015, up from 56.71 mills in 2014, which is an increase of approximately 1.9%. Power Supply Central Power’s two power supply resources, the Western Area Power Administration (WAPA) and Basin Electric Power Cooperative (Basin), comprise over 88 percent of Central Power’s operating expenses. Approximately 13 percent of Central Power’s power supply is federal hydropower produced from the mainstem Missouri River system and marketed by WAPA. The balance, or 87 percent, of our power is supplied rate incorporates a 4.84 mill decrease in the drought adder, to 11.83 mills, and an offsetting increase in the base rate The base rate will continue to be subject to the Federal Register process, but WAPA can recalculate the drought adder each year as additional revenue is needed to cover additional purchased power to meet its contracts or if above median water conditions should occur and the adder liability goes down. WAPA has the ability to adjust the drought adder up or down 2 mills a year without having to facilitate the public hearing process.

This is up from 52.01 mills per kWh, or 2.5%, in 2015. After holding the rate increase that Basin implemented in 2013, which incorporated a base demand rate of $16.74/ kW and an energy charge of 27.51 mills/kWh, through 2015, Basin’s power rates are increasing significantly in 2016. The base demand rate for 2016 is $18.06/kW, a 7.8% increase, while the energy rate is 29.55 mills/kWh, a 7.4% increase. Basin’s budgeted composite rate for 2016 to Central Power is 57.13 mills/kWh, an increase of 4.11 mills from 2015. The IS Lease Program, whereby Basin “leases” qualifying member-owned components of high voltage transmission facilities, was not modified. Under this lease arrangement, Basin has contracted rights to these facilities and they are included in the Integrated System (IS) and are therefore included in the tariff that is charged to all users of the Upper Missouri Zone (UMZ) in SPP.

All of these issues as well as the completion of the integration into SPP is shaping 2016 into being an unique and challenging year. Southwest Power Pool In October of 2015, the Central Power Board of Directors voted to have Central Power join the Southwest Power Pool(SPP) as a Transmission Owner. SPP is the regional transmission organization that both WAPA and Basin Electric had joined earlier. With this decision, Central Power was able to submit qualifying high voltage transmission facilities for inclusion into the tariff of the UMZ, the new zone created in SPP for the integration of WAPA and Basin into the RTO, and receive revenue requirements from SPP for providing those qualifying facilities. While the integration of Central Power into SPP is still on-going with negotiations and hearings in front of the Federal Energy Regulatory Commission, the revenues anticipated to be received from becoming a Transmission Owner in SPP are estimated to be $6.4 million. On a related note, the Integrated Transmission Agreement (ITA) between Central Power and Ottertail Power Company (OTP) expired on December 31, 2015. With no extension or carry-forward arrangement in place, both Central Power and OTP loads that were 12 Central Power Electric Cooperative, Inc.
