1 LMUD District Boundaries
LMUD STATS • Service territory is approximately 1,933 square miles. • 80 miles of 60kV transmission and 425 miles of distribution. • 2008 peak is approximately 30 MW. • Summer and winter peaks are within 1 MW of each other and remained relatively flat for the past several years. • We operate 9 substations – all served by a 60kV transmission system. 1
LMUD Transmission • LMUD has no internal generation of its own. • LMUD has a wholesale PPA with Western Area Power • The main power flow is through the 60kV PG&E Caribou Sub to LMUD’s Westwood Sub. • The is an alternate 60kV feed from PG&E’s Hat Creek Sub. • Westwood Sub have two 60kV circuits running from Westwood to the Milwood Sub in Susanville. • The line runs in the same ROW about 50% 0f the route. 1
The two circuit are run in parallel with two breakers in the Westwood Sub and two at Milwood. • Out of Milwood there is a 60kV circuit that runs to our Janesville and Standish Substations. • The line continues south to the backside of the Sierra Army Depot the line from Standish to the depot is de-energized. • The second 60kV circuit runs to Wendel were the Honey Lake Power Bio-mass Plant is located. • The plant wheels through our 60kV system to PG&E. 1

We have in our service area 3 co-generation plants. • 1 Biomass Plant – Honey Lake Power (HLP) • 35 MW nameplate (Generally runs at 27 to 28 MW) • 2 Small Geothermal Plants • 2 MW – Amedee (with planned expansion to 10MW) • 1 MW – Wineagle (New drilling is planned for the area for a 23.5MW goethermal Plant) • Generation from these plants is exported to PG&E through our Westwood meter point. 1
The capacity of LMUD’s transmission system is approximately 110MW. LMUD’s peak load is approximately 30MW which leaves 80MW for future growth in our system. • If we were to reserve 10MW for growth we could provide 70MW for renewable export with our existing 60kV transmission with some minor upgrades. • There are more constraints with the PG&E transmission systems from Westwood to Caribou with only 42MW of available capacity left at this point. • There are several developers who have requested capacity in our system which, at this point, cannot be provided. • The interest in Renewable Transmission excess is evident when we review the results of a meeting hosted by LMUD. 1
Proposed Renewable Projects • Also in attendance at the Renewable Transmission Planning Meeting were: • Fred Nagel (President, Lassen Municipal Utility District) • Jack Hansen (Lassen County Board of Supervisors) • John Ketelsen (Lassen County Administrative Officer) • Steve Thompson (Sr. Field Rep for Dan Logue) • Rocky Deal 1
There were additional developers who were unable to attend our meeting who are also interested in accessing transmission with another couple of hundred megawatts each. • We continue to this day to get calls from renewable developers asking about access to transmission through our system. • We meant this month with a geothermal developer interested in and interconnect for a 30MW plant in the Wendel area. Drilling may be started as early as March. 1

Line Upgrades? • Can LMUD provide additional capacity? • We have existing transmission rights of way (“ROW's) from Honey Lake Power in Wendel, through Susanville to our Westwood Substation. • This line could possibly be upgraded to a higher transmission voltage in the same corridor we presently have. • The voltage would be the determining factor in the width of the ROW. • At the higher voltages there may be need for a wider corridor which would require new easements and or acquisitions of additional ROWs. 1
LMUD’s 230kV Proposal • Lassen’s proposal is to build a double-circuit 230kV transmission line using a bundled conductor design to result in the maximum capacity for a 230kV system. • This would provide an east / west interconnection via the proposed 230kV line which could pick up various proposed renewable energy generation projects (“Projects”) within Lassen’s service territory. • A narrow profile, single pole transmission structure would be used in Lassen’s existing right-of-way and would wheel power from Viewland to a PG&E interconnection point near Westwood, CA. 1
Lassen believes that such a design is the best fit for Lassen County and this existing corridor. • The envisioned build-out of these facilities would allow Lassen the ability to draw on the most affordable sources of electricity to serve its customers and improve reliability provided by a stronger transmission grid. • The proposed line would also support local community economic development, address future energy demand growth, and support the region’s renewable energy goals, customer expectations and environmental priorities. 1

Phase I • Viewland Substation interconnection to Reno-Alturas Transmission Line 345/230kV • 230/60kV Build out 25.5 miles to Milwood Substation in Susanville. • Milwood Substation, build out 23 miles of 230kV line to Westwood Substation and Meter Point. Phase II • Westwood 230kV Substation Switchyard. • Permit and construct approximately 44 miles of 230kV double-circuit transmission line from the Westwood Substation, Westwood, CA, to the Round Mountain area northwest of the Burney area. 1
The ROW from Westwood to Round Mountain is a 60kV PG&E ROW and LMUD would need access to this ROW to build the line. 1
Miscellaneous • Additional Rights of Way • Scoping Meetings • Permitting – directed by Fed & State to streamline • Existing corridors (power lines already exist) • EIR & CEQA • Helps the State of California aggressively pursue 33% by 2020 RPS goal • Regional cooperation (IOUs and POUs) • LMUD’s primary contribution lies in the value of the ROWs • LMUD is pursuing available federal stimulus funding to assist with cost of project 1
Benefits for LMUD Consumers • Increases reliability for LMUD’s system • Revenues help LMUD stabilize rates. • Stable rates (energy costs, important for business—both existing and those looking to relocate). • Large potential for renewable energy development. • Construction jobs • Et Cetera 1
