Along the 150 mile Sunrise Powerlink route underground power lines can provide for:

Considerably higher electrical transmission capacities by using much heavier copper cables which do not require support structures and operate at lower temperatures than AC.
Total costs are several times less for underground DC than overhead AC when environmental restoration and property losses are included.
Underground DC cables can be continuously installed considerably faster than overhead power lines, at rates of up to 1 KM per day.
Underground DC can eliminate aircraft power line hazards, fires, falls and electrocution accidents.
Considerably greater security if provided against intentional harm with underground cables.
Underground lines are far more reliable in all storm conditions.
150 miles of underground cables protect over 350,000 acres, saving over $6 billion in property losses and environmental damages.
Underground cables can protect over 500,000 acres of viewshed along a 150 mile route.
Underground power lines significantly helps protect California's $90 billion per year tourist industry.
Underground power lines do not inflict losses of life to cancer at rates estimated to equal automotive fatalities, consequently saving billions of dollars per year in losses to families.
DC Power lines are not phase synchronized consequently help protect against network failures.
Homeland Security paid 60% of New York's underground power line installation costs to help create a more secure electric power network.
500kV DC can deliver over 3,000 megawatts on two 6 inch cables in one 5 foot deep trench.
Underground DC cable maintenance is extremely low, with vastly longer cable life than overhead AC, better heat dissipation and lower working temperatures.
A pair of 6 inch underground DC power lines can transmit 3,000 to 10,000 megawatts and save over $2 billion to $10 billion in future upgrade costs.
A 5% DC efficiency improvement compared to long haul AC can save over $2 billion in 2 - 4 decades.
Underground DC eliminates electro-magnetic fields and ionized pollutants which adhere to our lungs as carcinogens, both significant sources of cancer which are being denied by the power industry in spite of large scale medical studies.
Overhead high power lines across wilderness and rural areas damage California's $90 billion per year recreation and tourism industry, because Sempra engineers are more familiar with AC transformers and not particularly familiar with DC converters.
The California Environmental Quality Act (CEQA) requires that alternatives be provided to avoid environmental damages.
Overhead power lines cost $1.4 billion only if eminent domain and force are used to rob over $6 billion in immediate property losses, and the victims are not reimbursed for their full property losses.
If east San Diego County business, environmental and receration losses are included, along with restoration expenses, property replacement costs and losses due to cancer, over the life-span of the overhead power line then the total losses can easily exceed 10's of billions.
Sempra Energy could begin by paying for the full replacement cost of equivalent property based on access and setting, which they forcably build on, or within 2 miles, or which they damage, or negatively impact, including all environmental restoration costs at $75 per square foot plus irrigation system and well installation costs, over several decades. Damages are millions of times easier to create than to fully restore.

The people of California have made it clear in testimony and in writing that the Sunrise Powerlink being proposed by SDG&E does not represent their interests, nor address our sustainable energy needs, particularly through the degradation of over 500,000 acres of California’s scenic wilderness regions; nor by confiscating, damaging, inflicting losses or denying property uses on 10's of thousands of acres without equivalent, full and complete replacement of all property and losses incurred; and by initiating cancer through EMF or air born ionized pollutants.
